WebP to WebM Conversion FAQ
What does the WEBP to WEBM converter do?
+
It converts a WEBP file into WEBM format.
What happens to transparency when converting WEBP to WEBM?
+
WEBM does not support transparency. Transparent regions in the WEBP will be flattened against a solid background — white by default. If you need to keep transparency, convert to PNG, WebP, or TIFF instead.
What output quality should I expect from WEBP to WEBM?
+
Default settings target broadcast / web quality — visually identical to the source for most viewers. For archival use, pick the highest quality option in the converter settings.
Is there a file-size limit when converting WEBP to WEBM?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Can I batch-convert several WEBP files to WEBM at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
What happens to my WEBP files after the conversion?
+
Uploaded files are processed on our own conversion servers, nobody looks at them, and they are not shared. The upload and the converted file are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Will my WEBM play on phones, tablets, and TVs?
+
Yes — WEBM uses modern codecs that play natively on iOS, Android, Smart TVs, game consoles, and every modern browser.
Do I need to install software to convert WEBP to WEBM?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
Do I need an account to convert WEBP to WEBM?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
Is there an API for WEBP to WEBM conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. WEBP to WEBM is one of the supported pairs.
What if my WEBP fails to convert to WEBM?
+
Failures are usually caused by corrupted source files or unsupported WEBP variants. Re-export from the original app and try again; if it still fails, the contact page forwards the file to support so we can diagnose.
