Image compression is quite vernacular if you carry on with web uploads , a entanglement host , or a web log . We have been compact PNG ’s , JPG ’s , and even GIFs every single day to optimise the rendering metre of our website . It ’s a no brainer that belittled image sizes would make your website loading time faster . But , what are the tools that would avail you do that ?
Well , you’re able to also useUbuntu’sbuilt - inShotwell pic viewerapp . All you have to do is start the image , quality “ Save as ” and adjust the image qualityoptions consequently . However , Shotwell is not effective in size reduction and the personnel casualty in timbre is noticeable .
On that note , here ’s a collect list of good look-alike condensation apps for Linux which will not constrict images but also transform , edit , resize them for you .

Best Image Compression Apps For Ubuntu
Before we begin with the list , I would wish to note down a couple of things . We have a stock process where we use JPGs for color images and PNGs for text - free-base images . In general , PNG is a lossless compression and compressing them takes a hatful of time and the resolution in insignificantly small file size . So , you might be good withresizing a PNGrather than constrict it . JPGs are lossy concretion and compressing a JPG is much more worthwhile .
Command-Line Tools
1. ExifTool
EXIF and metadata comprise a underage part of the overall image Indian file size . In some vitrine , it is pointless to upload an icon with all the EXIF and metadata . In such a case , you could use the EXIF tool which can view , edit , and delete EXIF information . To view the EXIF data of your trope , use the following command .
To dispatch all the EXIF and metadata , employ the following command . Do note that , not all of the metadata can be cancel using any tool .

The bidding to compress an prototype is as follows . you could toggle the compression value by changing the time value beside the choice “ -compression_level ” .
Additionally , you may also scale trope in the same program line by adding “ -vf scale=675:407 ” . So the final bidding will look like the following .
you may also batch process images within a particular directory using FFmpeg . However , I would recommend doing that only if you are write a playscript for the server - side .

ImageMagic is the most advanced free statement - line software entourage available for image densification and use . It ’s fundamentally built to be used on RHEL or CentOS servers and patronize compaction for over 200 + ikon data format . However , you may still download and apply it on other Linux distros . For Debian - base , it ’s available in the apt repository and for other distros , you need to download and compile the reservoir codification . Below are the set of commands to do that .
ImageMagic has 2 commands , namely mogrify and win over , to compress , convert , and edit images . By default , mogrify modifies the original image whereas convert creates a modified copy of it . It ’s easy to batch compress multiple persona using these commands . In our case , it ’s deadening to transfer image one - by - one in GIMP or Photoshop and resize them . We upload images to our web site with a resolution of 675×450 pel . Hence , in club to batch convert all the screenshots to the required formatting , I execute the undermentioned program line . The “ * . * ” denotes that every file in the directory needs to be resize to 675×450 .
In case you get trope relegating misplay , you postulate to add the open - source libraries for the exceptional image file type . Head over tothis pagefor selective information .
