In case you really want to save storage space, you can do lossy compression on large JPEG pictures. Then it will simply print results without actually performing compression. If you simply check out possible lossless compression ratio without actually compressing it, use -n option to simulate compression.
Then a compressed image will be placed with the same date and time as the original image. If you want to preserve file creation/modification time, use -p option as follows. compressed photo.jpgĪn compressed image will then be placed (with the same name as the input file) in. If you want to preserve an original image, use -d option to specify a target directory. If jpegoptim is not able to further optimize an image losselessly, it will skip overwriting it. Note that the original input image will be overwritten with a compressed impage. To compress a JPG picture losslessly, simply run: $ jpegoptim photo.jpg
Compress jpeg install#
To install jpegoptim on CentOS/RHEL, first enable EPEL repository, and then run: $ sudo yum install jpegoptim To install jpegoptim on Fedora: $ sudo yum install jpegoptim To install jpegoptim on Ubuntu, Debian or Linux Mint: $ sudo apt-get install jpegoptim In case your storage or bandwidth budget is really low, jpegoptim allows you to do lossy compression as well by adjusting image quality.įor those interested in compressing PNG images, refer to this guideline instead. A command-line tool called jpegoptim allows you do lossless optimization on JPEG images, so you can compress JPEG pictures without sacrificing their quality. In fact, there is a way to compress JPEG images easily on Linux. While modern gadgets continue to produce increasingly high resolution images, we may often want to post-process and compress their sizes before uploading them to a storage-limited and bandwidth-restricted cloud. Even 36.3 Megapixel Nikon D800 recently hit the consumer market, and this trend will continue. Image resolution of today's picture taking gadgets (e.g., smartphones, digital cameras) keeps increasing. What is the easiest way to compress JPEG images without losing their quality on Linux? I would like to optimize and compress the JPEG pictures before uploading them to Dropbox. Question: I have several JPEG photo images I have taken using a digital camera.
