I'm desparately trying to convert PDF to JPG by Imagemagick (convert command) preserving trimbox.
I run following command (convert only first page).
convert -verbose -define pdf:use-trimbox=true "test_org.pdf[0]" cropped.jpg
Here is an output. Looks like imagemagick doesn't pass use-trimbox parameter to the ghostscript. May that be a reason? As at the moment converted image is mediabox size, not trimbox. Version of ImageMagick is 6.0.7, ghostscript GPL Ghostscript 8.64.
convert: **"gs" -q -dBATCH -dSAFER -dMaxBitmap=500000000 -dNOPAUSE -dAlignToPixels=0 "-sDEVICE=bmpsep8" -dTextAlphaBits=4 -dGraphicsAlphaBits=4 "-g652x935" "-r72x72" -dFirstPage=1 -dLastPage=1 "-sOutputFile=/tmp/magick-XXgTtZZG" "-f/tmp/magick-XXs4Kjq2" "-ftest_org.pdf".**

You possibly have too old ImageMagick. Works fine in my case.
Version: ImageMagick 6.6.0-4 2010-11-16 Q16 http://www.imagemagick.org
-define pdf:use-trimbox=true makes convert invoke gs with -dUseTrimBox option, which I don't see in output provided by you. Consider updating ImageMagick.
Your ImageMagick 6.0.7 is more than 6 years old (dozens of releases back). Current is 6.7.0-9.
Your Ghostscript 8.64 is also more than 2 years old already (5 releases back). Current is 9.02.
My recommendation is to upgrade.
On my (Windows) system I have IM 6.7.0-8 and GS 9.02. Running -define pdf:use-trimbox=true works fine here and translates to a Ghostscript commandline parameter of -dUseTrimBox=true.
However (and this is important!): one should take into account, that for many practical example PDFs out there, TrimBox is undefined, or explicitely set to the same values as MediaBox. Both have the same effect: a -dUseTrimBox=true will not make any difference in the output to a -dUseTrimBox=false.

I am using Ubuntu 18.04.1 LTS (Bionic Beaver) on Windows Subsystem for Linux. I installed ImageMagick according to these instructions, the only exception being ImageMagick version is currently 7.0.10-34, not 7.0.4-5: https://www.tutorialspoint.com/how-to-install-imagemagick-on-ubuntu.
I've downloaded a test .gif and successfully run commands like convert giphy.gif -flip new.gif and magick giphy.gif giphy.tif and identify giphy.gif, but when I try to run the same commands with "panda.jpg" or "15k4881.tif", I get the following errors:
$ identify panda.jpg
identify: no decode delegate for this image format `JPG' # error/constitute.c/ReadImage/562.
$ convert 15k4881.tif -flip 15k4881.tif
convert: no decode delegate for this image format `TIF' # error/constitute.c/ReadImage/562. convert: no images defined `15k4881.tif' # error/convert.c/ConvertImageCommand/3285.
I'm very, very new to all this but I can tell from the following outputs that .jpg, .tif, and .png are not supported nor have the proper delegates. What do I do to be able to modify these file types?

If you install ImageMagick from source, ensure you have the needed delegates.
Do something like the following: e.g. these steps are required in order to Install ImageMagick with JPG, PNG and TIFF delegates for example.
Update apt index:
sudo apt-get update
Install Build-Essential in order to configure and make the final Install:
sudo apt-get install build-essential
libjpg62-dev required in order to work with basic JPG files:
sudo apt-get install -y libjpeg62-dev
libtiff-dev is required in order to work with TIFF file format:
sudo apt-get install -y libtiff-dev
libpng-dev required in order to work with basic PNG files:
sudo apt-get install -y libpng-dev
Download ImageMagick:
wget https://www.imagemagick.org/download/ImageMagick.tar.gz
Untar Imagemagick:
tar xvzf ImageMagick.tar.gz
Access the working directory:
cd ImageMagick-*
Configure disabling the "shared" option and prefix installed source files with the stow dir path:
./configure --disable-shared --prefix=/usr/local/stow/ImageMagick
Compile, install and check:
sudo make && sudo make install && sudo make check
Stow the ImageMagick package:
cd /usr/local/stow/
stow ImageMagick
Ensure the above delegates are present:
identify --version

Gnu Stow will make easier uninstalling the package if you need to re-install it from scratch:

stow -D ImageMagick #it will remove the symlinked soruce files inside ../lib, ../bin, etc.
rm -rf ImageMagick/
You've built your own imagemagick from source.
This is not an easy thing to do -- you need a lot of other packages for it to all work correctly (for example, you must install the headers for libjpeg and libexif if you want to process jpeg images), you'll need quite deep knowledge of file formats and file format libraries, you'll need to think carefully about security and which delegates you need, and then once you've built it, you'll need to maintain it.
Instead, it's almost always better to just use Ubuntu's built-in imagemagick. Simply enter:
apt install imagemagick
And it'll download and install a tested and working copy of imagemagick, and it'll automatically keep it up to date as bugfixes are issued. You should probably remove the imagemagick that you built to reduce confusion.
I would only build from source if I absolutely had to have a more recent version of a package than was in the package repository, and even then I'd think twice. Or even three times.
FFmpeg now support librsvg support for SVG rasterization.
I have tried the following command:
ffmpeg -i test.svg test.png
But I get the following error:
Decoder (codec svg) not found for input stream #0:0
I have search the doc but there is no examples given. Can someone tell me how to a command line using ffmpeg to generate a PNG from a SVG file?
Your ffmpeg needs to be compiled with --enable-librsvg. If you're compiling ffmpeg then you need to install whatever package provides the librsvg header files. For example, in Arch Linux it is librsvg, and in Ubuntu it is librsvg2-dev.
Series of images
Usage is similar to using raster images as inputs with the image demuxer. For example, a series of images named vector-001.svg, vector-002.svg, vector-003.svg, etc:
ffmpeg -i vector-%03d.svg -vf format=yuv420p output.mp4
Single image
ffmpeg -i input.svg output.png
With custom size:
ffmpeg -width 600 -i input.svg output.png
-keep_ar true is the default, so it will automatically calculate height in this example to preserve the aspect ratio.
Decoder specific options
The decoder librsvg has a few input options:
$ ffmpeg -h decoder=librsvg
[…]
-width <int> .D.V...... Custom width to render to (0 for default) (from 0 to INT_MAX) (default 0)
-height <int> .D.V...... Custom height to render to (0 for default) (from 0 to INT_MAX) (default 0)
-keep_ar <boolean> .D.V...... Keep aspect ratio with custom width/height (default true)
I am facing an issue with time taken by imagemagic to execute the commands on my server. I also tried to make thread control from 20(default) to 1 but, no improvements.
Here are some of the commands we fire and time took for them on server. Is there any way to reduce this execution time?

Does this get you any faster?
convert input.png -quality 80% -resize 4518x3013! \
\( +clone -crop 2408x3010+1053+0 +repage \) \
-geometry +564+564 -composite output.png
For really fast PNG writing, use -quality 10 for drawings, -quality 11 for photos. This should cut your PNG-writing time by a factor of five.
The "quality" number doesn't affect image quality when writing a PNG. It only affects the compression effectiveness.
I have a two-page PDF I'm trying to convert to a PNG file. When I run:
gs -sDevice=pngalpha -o=gs-output-%d.png -r400 test1-0.pdf
I get:
GPL Ghostscript 9.07 (2013-02-14)

And then... nothing. No output files at all. Where am I going wrong?
You're so close you'll be mad ;-)
After a bit of manpage reading here's what worked for me:
gs -sDEVICE=pngalpha -ogs-output-%d.png -r400 test1-0.pdf
i.e. DEVICE instead of Device, and -o instead of -o=
In case it matters, my gs version is:
GPL Ghostscript 9.05 (2012-02-08)
try this which works perfectly with me and it get a very good results:
-sDEVICE=pngalpha -o "$OUTPUTIMAGEFILE" -dFirstPage=1 -dLastPage=2 -dNOPAUSE -dGraphicsAlphaBits=4 -dTextAlphaBits=4 "$INPUTPDFFILE"
However i guess that using -r400 is for JPEG images not PNGS
Is Ghostscript the best option if you want to optimize a PDF file and reduce the file size?
I need to store alot of PDF files and therefore I need to optimize and reduce the file size as much as possible
Does anyone have any experience with Ghostscript and/or other?
command line
exec('gs -dNOPAUSE -dBATCH -sDEVICE=pdfwrite -dCompatibilityLevel=1.4
-dPDFSETTINGS=/screen -sOutputFile='.$file_new.' '.$file);
If you looking for a Free (as in 'libre') Software, Ghostscript is surely your best choice. However, it is not always easy to use -- some of its (very powerful) processing options are not easy to find documented.
Have a look at this answer, which explains how to execute a more detailed control over image resolution downsampling than what the generic -dPDFSETTINGS=/screen does (that defines a few overall defaults, which you may want to override):
How to downsample images within pdf file?
Basically, it tells you how to make Ghostscript downsample all images to a resolution of 72dpi (this value is what -dPDFSETTINGS=/screen uses -- you may want to go even lower):
-dDownsampleColorImages=true \
-dDownsampleGrayImages=true \
-dDownsampleMonoImages=true \
-dColorImageResolution=72 \
-dGrayImageResolution=72 \
-dMonoImageResolution=72 \
If you want to try if Ghostscript is able to also 'un-embed' the fonts used (sometimes it works, sometimes not -- depending on the complexity of the embedded font, and also on the font type used), you can try to add the following to your gs command:
gs \
-o output.pdf \
[...other options...] \
-dEmbedAllFonts=false \
-dSubsetFonts=true \
-dConvertCMYKImagesToRGB=true \
-dCompressFonts=true \
-c ".setpdfwrite <</AlwaysEmbed [ ]>> setdistillerparams" \
-c ".setpdfwrite <</NeverEmbed [/Courier /Courier-Bold /Courier-Oblique /Courier-BoldOblique /Helvetica /Helvetica-Bold /Helvetica-Oblique /Helvetica-BoldOblique /Times-Roman /Times-Bold /Times-Italic /Times-BoldItalic /Symbol /ZapfDingbats /Arial]>> setdistillerparams" \
-f input.pdf
Note: Be aware that downsampling image resolution will surely reduce quality (irreversibly), and dis-embedding fonts will make it difficult or impossible to display and print the PDFs unless the same fonts are installed on the machine....
Update
One option which I had overlooked in my original answer is to add
-dDetectDuplicateImages=true
to the command line. This parameter leads Ghostscript to try and detect any images which are embedded in the PDF multiple times. This can happen if you use an image as a logo or page background, and if the PDF-generating software is not optimized for this situation. This used to be the case with older versions of OpenOffice/LibreOffice (I tested the latest release of LibreOffice, v4.3.5.2, and it does no longer do such stupid things).
It also happens if you concatenate PDF files with the help of pdftk. To show you the effect, and how you can discover it, let's look at a sample PDF file:
pdfinfo p1.pdf
Producer: libtiff / tiff2pdf - 20120922

Recent versions of Poppler's pdfimages utility have added support for a -list parameter, which can list all images included in a PDF file:
pdfimages -list p1.pdf
page num type width height color comp bpc enc interp objectID x-ppi y-ppi size ratio
--------------------------------------------------------------------------------------
1 0 image 423 600 rgb 3 8 jpeg no 7 0 52 52 19.2K 2.6%
This sample PDF is a 1-page document, containing an image, which is compressed with JPEG-compression, has a width of 423 pixels and a height of 600 pixels and renders at a resolution of 52 PPI on the page.
If we concatenate 3 copies of this file with the help of pdftk like so:
pdftk p1.pdf p1.pdf p1.pdf cat output p3.pdf
then the result shows these image properties via pdfimages -list:
pdfimages -list p3.pdf
page num type width height color comp bpc enc interp objectID x-ppi y-ppi size ratio
--------------------------------------------------------------------------------------
1 0 image 423 600 rgb 3 8 jpeg no 4 0 52 52 19.2K 2.6%
2 1 image 423 600 rgb 3 8 jpeg no 8 0 52 52 19.2K 2.6%
3 2 image 423 600 rgb 3 8 jpeg no 12 0 52 52 19.2K 2.6%
This shows that there are 3 identical PDF objects (with the IDs 4, 8 and 12) which are embedded in p3.pdf now. p3.pdf consists of 3 pages:
pdfinfo p3.pdf | grep Pages:
Pages: 3
Optimize PDF by replacing duplicate images with references
Now we can apply the above mentioned optimization with the help of Ghostscript
gs -o p3-optim.pdf -sDEVICE=pdfwrite -dDetectDuplicateImages=true p3.pdf
Checking:
pdfimages -list p3-optim.pdf
page num type width height color comp bpc enc interp objectID x-ppi y-ppi size ratio
--------------------------------------------------------------------------------------
1 0 image 423 600 rgb 3 8 jpeg no 10 0 52 52 19.2K 2.6%
2 1 image 423 600 rgb 3 8 jpeg no 10 0 52 52 19.2K 2.6%
3 2 image 423 600 rgb 3 8 jpeg no 10 0 52 52 19.2K 2.6%
There is still one image listed per page -- but the PDF object ID is always the same now: 10.
ls -ltrh p1.pdf p3.pdf p3-optim.pdf
-rw-r--r--# 1 kp staff 20K Jan 6 19:36 p1.pdf
-rw-r--r-- 1 kp staff 60K Jan 6 19:37 p3.pdf
-rw-r--r-- 1 kp staff 16K Jan 6 19:40 p3-optim.pdf
As you can see, the "dumb" concatentation made with pdftk increased the original file size to three times the original one. The optimization by Ghostscript brought it down by a considerable amount.
The most recent versions of Ghostscript may even apply the -dDetectDuplicateImages by default. (AFAIR, v9.02, which introduced it for the first time, didn't use it by default.)
You can obtain good results by converting from PDF to Postscript, then back to PDF using
pdf2ps file.pdf file.ps
ps2pdf -dPDFSETTINGS=/ebook file.ps file-optimized.pdf
The value of argument -dPDFSETTINGS defines the quality of the images in the resulting PDF. Options are, from low to high quality: /screen, /default, /ebook, /printer, /prepress, see http://milan.kupcevic.net/ghostscript-ps-pdf/ for a reference.
The Postscript file can become quite large, but the results are worth it. I went from a 60 MB PDF to a 140 MB Postscript file, but ended up with a 1.1 MB optimized PDF.
I use Ghostscript with following options taken from here.
gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/screen \
-dNOPAUSE -dQUIET -dBATCH -sOutputFile=output.pdf input.pdf
You may find that pdftocairo (from Poppler) can make smaller PDFs but beware that it will strip some features (such as hyperlinks) away.
This worked for me
Convert your PDF to PS (this creates a large file
pdf2ps large.pdf very_large.ps
Convert the new PS back to a PDF
ps2pdf very_large.ps small.pdf

You will lose in quality but if it's not an issue then ImageMagick's convert may proves helpful :
convert original.pdf reduced.pdf
Note that it doesn't always work : I once converted a 126 MB file into a 14 MB one using this command, but another time it doubled the size of a 350 Ko file.
Anyway it's worth giving it a try…
As mentioned in comments, of course there is no point in applying this command on a vector-based PDF, it will only be useful on rasterized images.
See also this post for related options.
Ghostscript comes with ps2pdf14 utility which can be used to optimise PDF file(s) but on some occasions size of "optimised" file may be bigger than original.
For the PDF which size is mainly due to embedded images (pdfimages -list is your friend), typically scanned documents, I would recommend the use of ocrmypdf which is quite good at optimizing, with optional OCR layer as a bonus.
