Free, in your browser — your image never leaves you. Transparent areas become white.

Converting…
RoundCut converts WebP to JPG entirely in your browser. The file is never uploaded — verify in DevTools. JPG is lossy, so some quality is discarded, but at the default setting the difference is visually negligible for photos. Transparent areas become white, since JPG has no alpha channel.
You downloaded an image and it landed as a .webp file. Instagram won't accept it. Your email client refuses to attach it. The upload form on a job site, a school portal, or an old CMS rejects it. WebP is Google's modern format and most browsers display it fine, but a long tail of apps and platforms still only take JPG. Convert it here and the file you get back uploads anywhere a regular photo would — no app install, no extension, no account.
Drop the WebP on the upload area, or click to pick one. The conversion runs the instant the file lands — no Convert button, no queue, no upload wait. When the JPG is ready, the stats line shows the input and output size, and the Download button saves it to your device. The whole round-trip is typically under a second for a phone photo, and the page stays loaded so you can drop the next file straight on top without reloading anything.
The conversion runs in the platform's own image engine, on your device. Nothing is uploaded, nothing is logged, nothing is queued on a server. Every other top-ranked WebP to JPG converter posts your file to their backend — files-deleted-after-X-hours is the giveaway. Ours doesn't, because there is no backend to delete from. Open DevTools, switch to the Network panel, then convert a file — you will see zero outbound image requests anywhere in the trace. The same code path runs on every browser.
JPG is a lossy format — every WebP to JPG conversion permanently discards some color data. At our default encode setting the difference is visually indistinguishable from the source for photographs. For graphics with sharp edges or solid color blocks, the WebP itself is the better keep. WebP can carry transparency; JPG cannot. Transparent pixels are flattened to white on output. If you need transparency, convert to PNG instead — and ignore any tool that claims a lossless WebP to JPG.
Quick answers to the questions people most often have about converting WebP to JPG — quality, transparency, Instagram, metadata, and batches. Each answer below is honest about the trade-offs the format change brings, including the ones competitor tools quietly skip in their marketing copy. If a question you have is missing, the lib documentation in our public repository covers every limit and capability in finer detail. The short version: this tool converts one file at a time, fully on your device, with no upload, no signup, and no watermark on the output — and we will not tell you a lossy format is lossless to make ourselves sound better than the next page in the results.
Instagram does not accept WebP uploads — only JPG and PNG go through. Drop your WebP on the upload area above, wait for the JPG to appear (usually under a second), download it, then upload that file to Instagram normally. No account, no app install, no extension, no browser permission prompt. The conversion runs entirely on your device.
Yes — JPG is a lossy format, so every WebP to JPG conversion discards some color data permanently. At our default encode setting the difference is visually negligible for photographs. For perfect pixel preservation, convert to PNG instead. Any tool that claims a lossless WebP to JPG conversion is incorrect — the JPG format itself makes that impossible by design.
JPG has no alpha channel, so transparent pixels in your WebP become solid white in the JPG. There is no setting that preserves transparency in a JPG, because the format itself does not support it. If you need to keep transparency, convert to PNG instead. If you need a non-white background, paint the color onto the WebP in an editor first.
No. The conversion runs entirely on your device using the platform's native image engine. Open your browser's DevTools, switch to the Network panel, then convert a file — you will see zero outbound image requests during the conversion. There is no server fallback path, no telemetry on file contents, and no account or cookie tied to the file you converted.
WebP is an image format Google built for smaller file sizes on the web. You most likely got it by right-clicking and saving an image from a modern website. WebP is great for the web but a long list of apps, email clients, and upload forms still only accept JPG — which is why this conversion is a normal everyday task, not a problem on your end.
Not yet — this tool converts one file at a time. Batch conversion is planned for a later release. For now, repeat the drop-and-download cycle per file. Each conversion is typically under a second on a phone photo, and the page does not need to reload between files, so working through a folder stays quick.
