PNG to WebP Conversion FAQ
What does the PNG to WEBP converter do?
+
PNG is a lossless image format; WEBP uses lossy compression. The converter re-encodes pixel data into WEBP, trading some fine detail for a smaller file. For photographs this is usually invisible; for sharp graphics it can introduce halos around edges.
How much smaller will the WEBP be than my PNG?
+
Typically 5-10x smaller for images, 5-15x smaller for audio. Exact ratio depends on the chosen quality level and the content — flat solid-colour images and silent audio compress far more than detailed photos or busy soundtracks.
Is there a file-size limit when converting PNG to WEBP?
+
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 PNG files to WEBP 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 PNG 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.
Where can I open a WEBP file?
+
WEBP opens natively in every modern browser, every image viewer, and every photo-editing app. No additional software is needed.
Do I need to install software to convert PNG to WEBP?
+
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 PNG to WEBP?
+
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 PNG to WEBP conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. PNG to WEBP is one of the supported pairs.
What if my PNG fails to convert to WEBP?
+
Failures are usually caused by corrupted source files or unsupported PNG 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.
