WebP to JPG Converter
Convert a WebP image to a JPG that opens everywhere — right in your browser, with adjustable quality, no upload and no watermark.
Short answer
To convert WebP to JPG, drop your WebP below, pick a quality, and download the JPG. WebP is a modern web format some older apps won’t open; JPG works everywhere. It all runs in your browser — your image is never uploaded, and it works offline. Transparent areas are filled with white, since JPG has no transparency.
Why won’t my WebP open?
WebP is a format Google created to make web images smaller, and it’s now common on websites. But some desktop apps, older photo editors, and upload forms still don’t accept it — which is why a WebP you saved from the web sometimes won’t open or upload. Converting it to JPG, the most universally supported photo format, fixes that instantly.
WebP vs. JPG
WebP usually produces a smaller file than JPG at the same quality and can store transparency, which is why the web loves it. JPG is older, larger for the same quality, and has no transparency — but it opens in everything. Convert to JPG when compatibility matters more than file size; keep WebP when you control where the image is used.
How we calculate this
Conversion happens locally in your browser — here's exactly how:
- Decode. your WebP is decoded to a bitmap in the browser (via createImageBitmap) — never uploaded to any server.
- Flatten transparency. because JPG has no alpha channel, transparent pixels are painted onto a solid background (white by default) first.
- Draw. the bitmap is drawn to an HTML canvas at its original dimensions.
- Encode. the canvas is exported with canvas.toBlob('image/jpeg') at your chosen quality, producing the downloadable JPG.
Assumptions
- Everything runs client-side; large images are limited only by your device's memory.
- JPG is lossy — some detail is re-encoded; keep quality high to minimize it.
- Transparency cannot be preserved in JPG; convert to PNG if you need it.

Frequently asked questions
How do I convert a WebP to JPG?+
Drop your WebP file in above, pick a quality, and download the JPG. The conversion runs entirely in your browser, so your image is never uploaded, and it works offline once the page has loaded. WebP images downloaded from the web often won't open in older apps — converting to JPG fixes that.
Are my images uploaded to a server?+
No. The converter runs 100% in your browser using the HTML canvas, so your WebP never leaves your device. Nothing is stored or sent anywhere — private and fast, with no signup or watermark.
Why won't my WebP image open, and why convert to JPG?+
WebP is a modern format many websites use to save bandwidth, but some older apps, editors, and platforms don't accept it. Converting to JPG makes the image open and upload everywhere. JPG is also great for photos and usually a small file.
What happens to a transparent WebP?+
WebP can store transparency, but JPG can't — so any transparent areas are filled with a solid background (white by default) during conversion. If you need to keep the transparent background, convert to PNG instead of JPG.
Will converting reduce the image quality?+
JPG uses lossy compression, so some detail is re-encoded — but at a high quality setting (around 85–95%) the difference is usually invisible. Because your WebP was likely already compressed, keep the quality high to avoid stacking losses; lower it only if you need a smaller file.
Can I convert several WebP files at once?+
This tool converts one image at a time so you can set the quality and preview each result. Convert and download one, then drop in the next — no page reload needed.
