GIF (Graphics Interchange Format) and APNG (Animated Portable Network Graphics) are built for different jobs. GIF is typically used for short loops, memes, reactions, while APNG is best for high-quality animated stickers. Converting lets you open, share or upload your files wherever APNG is expected.

Frequently asked questions
How do I convert GIF to APNG?
Add your GIF files above, make sure APNG is selected and press Convert. The APNG files are ready to download a few seconds later — no installation or account required.
Why does the first conversion take a little longer?
The video engine (FFmpeg compiled to WebAssembly, about 30 MB) is downloaded once and then cached by your browser. After that, conversions start immediately — even offline.
Is there a file size limit?
There is no artificial limit. Because the conversion runs in your browser, the practical limit is your device memory — files up to around 1–2 GB work on most computers. Long videos take longer on phones.
Are my GIF files uploaded to a server?
No. ConvertMathly converts files entirely inside your web browser using JavaScript and WebAssembly. Your files never leave your computer or phone, which makes it safe for private photos and documents.
Can I convert multiple GIF files at once?
Yes — add as many files as you like. They are converted one after another and you can download everything in a single ZIP.
