1Upload the WebP images that came out the wrong way round.
2Pick a quarter turn or a half turn, or type an arbitrary angle and choose a colour for the corners it will expose.
3Apply the rotation; the pixels and the orientation flag are reconciled so every viewer agrees on which way is up.

Rotate WebP FAQ
Can I rotate a whole batch in one go?
+
Yes. The same rotation is applied across every file you upload, which is the practical fix for a folder of scans or camera output that all came in the wrong way round.
Can I rotate by an arbitrary angle, not just 90 degrees?
+
Yes, though the two are different operations underneath. A multiple of 90 degrees rearranges existing data; any other angle has to rebuild the grid and fill the corners, so it costs a resample and usually wants a background colour choosing.
Does the format decide whether rotation is lossless?
+
It does. WebP carries both a lossy VP8 mode and a lossless mode plus full alpha, typically landing 25-35% under a JPG of matching visual quality. That property is exactly what determines whether a quarter turn is free or costs a re-encode.
Anything specific to WebP I should know?
+
Yes — the same .webp extension can hold a lossy VP8 frame, a lossless one, or an animation, so the sensible processing path is decided per file rather than per extension. It is the kind of thing that explains why a file looks right in one application and wrong in another.
Will Rotate WebP lower the quality of my WebP images?
+
A lossy source is already the result of one quantisation pass, and any operation that has to re-encode adds a second. Where the job can be done without touching the pixel data we do that instead, and where it cannot you choose the quality factor yourself rather than getting a fixed default.
Can I run Rotate WebP on several WebP images at once?
+
Yes. Drop the whole set into the upload area and they queue in parallel with identical settings — that is the main reason to do this in a browser rather than one file at a time in an editor. Free accounts run one file per batch; a pass lifts that.
What happens to EXIF and colour profile data?
+
Camera EXIF (ISO, shutter, lens, GPS) and the embedded ICC profile are carried across by default, because dropping the profile is what makes colours shift on re-import. Use the privacy option to strip metadata before download if you are about to publish the file.
Does Rotate WebP cost anything?
+
No. Rotate WebP is free with no account, no watermark on the output and no signup wall in front of the download. Uploads are deleted automatically a short time after the job finishes.
Why does a WebM site host Rotate WebP?
+
WEBM.to is built around the container the open web actually chose — VP9 or AV1 with Opus audio, decoded natively by every modern browser and needing no plugin, licence or player. Video is the case where extra round trips hurt most — the files are large and every upload costs real minutes. Running Rotate WebP on the same pipeline as the conversions means one upload covers the whole job instead of one upload per tool.
What should I do with the result once Rotate WebP is finished?
+
The converter on this site moves video between WebM, MP4, MKV, MOV and the rest, or pulls the soundtrack out entirely, without another upload. Sequencing it that way matters more for video than anywhere else: each re-encode is another generation, so the fewer of them stand between the source and the file you publish, the better it looks.
Is Rotate WebP here the same tool the sibling sites run?
+
The engines are shared — the same ffmpeg build with x264, x265 and libvpx, the same workers, the same limits. What a WebM site adds is a view on containers and codecs: which combinations play everywhere, which need a re-encode and which can simply be copied across. It also starts from one fact about the format this site is named after: WebM is VP9 or AV1 with Opus audio, which browsers decode natively but which most desktop editors still transcode on import.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploaded video is deleted from the workers shortly after the job finishes, nothing is watched and nothing is indexed. Free accounts exist for history and batch size, not for access.
