Worker can be disabled by passing false instead of options hash or by setting option :disable to true. :timeout - Maximum time in seconds to spend on one image, note multithreading and cache (defaults to unlimited).:cache_worker_digests - Also cache worker digests along with original file digest and worker options: updating workers invalidates cache.:allow_lossy - Allow lossy workers and optimizations (defaults to false).:skip_missing_workers - Skip workers with missing or problematic binaries (defaults to false).:pack - Require image_optim_pack or disable it, by default image_optim_pack will be used if available, will turn on :skip-missing-workers unless explicitly disabled (defaults to nil).:verbose - Verbose output (defaults to false).:threads - Number of threads or disable (defaults to number of processors).:nice - Nice level, priority of all used tools with higher value meaning lower priority, in range -20.19, negative values can be set only if run by root user (defaults to 10).Temporary directory can be changed using one of TMPDIR, TMP or TEMP environment variables. Image_optim uses standard ruby library for creating temporary files. Nice: 20 pngout: false # disable optipng: Pack doesn't include pngout and svgo binaries, their installation instructions are provided below.
IMAGEOPTIM. MAC OS X
PATH="/Applications/ImageOptim.app/Contents/MacOS:$PATH" image_optim *.jpgĮNV = "/custom/location:#" ImageOptim.optimize_images()Įasiest way to get latest versions of most binaries for image_optim for Linux and Mac OS X is by installing image_optim_pack gem.Ĭheck installation instructions in Gem installation section. PATH="/custom/location:$PATH" image_optim *.jpg Specify custom bin location using XXX_BIN environment variable ( JPEGOPTIM_BIN, OPTIPNG_BIN, …).īesides permanently setting environment variables in ~/.profile, ~/.bash_profile, ~/.bashrc, ~/.zshrc, … they can be set:
IMAGEOPTIM. INSTALL
If you cannot install to common location, then install to custom one and add it to PATH. Simplest way for image_optim to locate binaries is to install them in common location present in PATH (see Binaries installation). See image_optim_pack repository for Dockerfile and instructions.
IMAGEOPTIM. FREE
Compressing images with the website is free for everyone and we like to keep it that way! If you like TinyPNG please contribute by making a donation.Docker run -rm ghcr.io/toy/image_optim -version # image_optim versionĭocker run -rm ghcr.io/toy/image_optim -info # image_optim info including bin versionsĭocker run -rm -v " $PWD ":/here -w /here ghcr.io/toy/image_optim image-in-this-folder.jpg In 2014 we added intelligent compression for JPEG images and in 2016 we added support for animated PNG. We created TinyPNG in our quest to make our own websites faster and more fun to use with the best compression. Why did you create TinyPNG?Įxcellent question! We frequently use PNG images, but were frustrated with the load times. It allows you to scale, preview and save compressed PNG and JPEG images straight from Photoshop. You can also install the TinyPNG Photoshop plugin. We’ll convert them to tiny indexed PNG files. You can use Save for Web to export your images as 24-bit transparent PNG files and upload them to TinyPNG. With other versions it is impossible and Photoshop CS5 cannot even display them properly. What about Photoshop?Įxcellent question! Only Photoshop CC 2015 or newer can save images as indexed PNG files with alpha transparency. If you want to create and compress stickers under 500 KB take a look at the iMessage Panda sticker example on Github. Only Internet Explorer does not support the format yet.Īpple added animated stickers to iMessage with the release of iOS 10. Binary transparency without any workarounds! Is it safe to use animated PNG?Įxcellent question! Chrome, Firefox, Safari and now Microsoft Edge all support APNG. With TinyPNG the background becomes transparent again. Still need to support Internet Explorer 6? It normally ignores PNG transparency and displays a solid background color. Is it supported everywhere?Įxcellent question! The files produced by TinyPNG are displayed perfectly on all modern browsers including mobile devices. I have excellent eyesight but can’t spot the difference either! Use the optimized image to save bandwidth and loading time and your website visitors will thank you. In the above image the file size is reduced by more than 70%. The result better PNG files with 100% support for transparency. All unnecessary metadata is stripped too. By reducing the number of colors, 24-bit PNG files can be converted to much smaller 8-bit indexed color images. File size 57 KB vs Shrunk transparent PNGĮxcellent question! When you upload a PNG (Portable Network Graphics) file, similar colors in your image are combined.
