Is my file uploaded when converting WebP to JPEG?

No. The conversion runs entirely in your browser. The file never leaves your device, there is no server to upload to, and the page works offline once loaded.

Is WebP to JPEG conversion free?

Yes, with no account, no watermark and no file limit per day. frogConvert is open source and there is no server cost to recover, because your device does the work.

How large a file can I convert?

Up to 2 GB for a single file, 500 MB total per batch, and 300 files at once. The practical limit is your device's memory, since everything is processed locally.

What to expect

Transparency is flattened, and re-encoding lossy WebP as lossy JPEG loses a little more detail.

Why convert WebP without uploading

Most online converters take your file, send it to their servers, convert it there and hand back a download link. That means your document sits on someone else's disk, subject to their retention policy and their breaches. It also means you cannot use them offline, and cannot use them at all for anything confidential.

frogConvert does the conversion in the page itself, with the browser canvas. There is no upload step because there is no server. You can disconnect from the network and it still works.

About the formats

WebP

Google's image format, with both a lossy mode derived from VP8 and a true lossless mode, plus alpha and animation. It generally beats JPEG and PNG on size at matched quality. More about WebP files.

JPEG

The dominant photographic format, using discrete cosine transform compression that discards detail the eye is least likely to notice. It has no transparency, and every re-save loses a little more. More about JPEG files.
