Panda says: Excellent question! When you upload a PNG (Portable Network Graphics) file, similar colors in your image are combined. This technique is called “quantization”. By reducing the number of colors, 24-bit PNG files can be converted to much smaller 8-bit indexed color images. All unnecessary metadata is stripped too. The result better PNG files with 100% support for transparency. Have your cake and eat it too!

In the above image the file size is reduced by more than 70%. 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.

Panda says: Excellent question! The files produced by TinyPNG are displayed perfectly on all modern browsers including mobile devices. Still need to support Internet Explorer 6? It normally ignores PNG transparency and displays a solid background color. With TinyPNG the background becomes transparent again. Binary transparency without any workarounds!

Panda says: Excellent question! Chrome, Firefox, Safari and now Microsoft Edge all support APNG. Only Internet Explorer does not support the format yet.

Apple added animated stickers to iMessage with the release of iOS 10. If you want to create and compress stickers under 500 KB take a look at the iMessage Panda sticker example on Github.

Panda says: Excellent question! We frequently use PNG images, but were frustrated with the load times. We created TinyPNG in our quest to make our own websites faster and more fun to use with the best compression. In 2014 we added intelligent compression for JPEG images and in 2016 we added support for animated PNG. Compressing images with the website is free for everyone and we like to keep it that way!
