![]() The setup takes only minimal effort on your part, freeing you up to focus on developing websites and apps. To recap, applying lossy compression to animated GIFs yields two major benefits: the flexibility of displaying those lively GIFs and the bandwidth savings from smaller yet still-visually-pleasing images, not to mention an enhanced user experience. Voila! The optimized GIF size is only 765 KB, 60 percent less than the original size of 1.9 MB. Apply lossy compression with a quantity value of 50 percent.Resize the overlay to a width of 40 pixels, positioned 5 pixels from the top-right corner of the animated GIF and make the overlay 40 percent semitransparent. Add an uploaded PNG image named cloudinary_icon as an overlay.Crop the GIF to a width of 50 percent and a height of 80 percent.So, instead of optimizing the original, large animated GIF, you can optimize a transformed or cropped version for display.įor example, these steps generate and deliver a calibrated version of the kitten GIF: Lossy compression can also optimize generated images. You can apply lossy compression on Cloudinary with any of the platform’s rich set of image optimization and transformation capabilities to match any graphic design, dimension, device, browser, responsive layout, and such. Enabling lossy compression and setting the quality parameter to 50 for the kitten GIF produces a 2.1-MB image, approximately 30 percent of the original size: The optimized GIF, as shown below, looks just as sharp as the original.Īn excellent tip on GIF compression: to fine-tune the level of lossy compression in compressed animated GIFs, add the quality parameter ( q in URLs), whose default value is 80. For example, this animated GIF named kitten_fighting, already uploaded to Cloudinary, is 6.3 MB in size.Īdding the fl_lossy parameter to the delivery URL reduces that size by 40 percent to 2.5 MB. Why? Because the compression process takes place in the cloud.Īll you need to do is set the flag parameter to lossy ( fl_lossy in URLs). With Cloudinary, you apply lossy compression through the platform’s on-the-fly, dynamic URLs with no need for any software or additional computational power. Optimizing animated GIFs with a lossy-compression technique yields smaller yet visually appealing images, a win-win. 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.Applying Lossy Compression to Animated GIFs 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. ![]()
