Drop APNG (animated PNG) files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab and can take a while for large files.
Save the WebM, or download everything as one ZIP if you converted several files.
The APNG to WebM converter is part of this page and runs inside your browser. Your animations are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so work starts the moment you press Convert. How long it takes depends on your device and the size of the file.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
APNG is lossless and large, and many apps show only its first frame. WebM is royalty-free and well suited to embedding in web pages. APNG is at home in animated stickers and graphics that need real transparency; WebM is the usual choice for royalty-free video on websites.
The defaults suit most files. Under Options you can set the frame rate, set the width and trim the start and end. This is demanding work for a browser: a long or high-resolution file can take several minutes, and your device does all of it, so keep the tab open.
This pair uses the compatibility engine, ffmpeg built for the browser, because APNG is not handled by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB.
APNG extends PNG with animation while staying backwards compatible: a program that knows only PNG shows the first frame. Unlike GIF it has 24-bit colour and a full alpha channel. Firefox pioneered it and every major browser now plays it.

No. The APNG to WebM conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
The content is carried over as faithfully as WebM allows; features that WebM does not have are left out.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the APNG file, press Convert and save the WebM. There is nothing to install.
Yes. APNG to WebM runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
