WebP to JPG

Convert website WebP images into plain JPGs that older software actually opens.

runs entirely in your browser

Why people convert away from a perfectly good format

Websites serve WebP because it packs the same visual quality into files roughly 25 to 35 percent smaller than JPG. All modern browsers handle it fine. The problem lives outside the browser: older photo editors, print services, embroidery and cutting software, and plenty of upload forms were written before WebP existed and reject it outright.

JPG is the interchange format everything agrees on. When a WebP you saved needs to go somewhere that says "JPG or PNG only", converting is faster than arguing with the software. This tool does exactly that one job.

Transparency, quality, and what to expect

Your browser decodes the WebP natively, the tool draws it to a canvas, and re-encodes it as JPG at the quality you set with the slider. One important behavior: JPG has no transparency, so if the WebP has transparent regions they get flattened onto a white background. If you need the transparency kept, use the WebP to PNG converter instead.

Because WebP compresses more efficiently, the JPG that comes out may be about the same size or larger than the WebP that went in; you are paying for compatibility, not saving space. The canvas re-encode also strips any embedded metadata, which is worth knowing if you care about it either way.

fair questions

Do you upload my WebP files?
No. The conversion happens entirely inside your browser and the image never leaves your device. There is no server-side processing, no storage, and no log of what you converted.
What happens to transparent areas of the image?
They are flattened onto a white background, because the JPG format has no alpha channel to store them in. If the transparency matters, convert to PNG instead, which preserves it fully.
Will the JPG be bigger than the WebP?
Often, yes. WebP is roughly 25 to 35 percent smaller than JPG at similar quality, so converting in this direction usually gives up that saving. The exact result depends on the image and the quality slider setting.
What quality setting should I pick?
Keep the slider high if the image will be edited, printed, or viewed large; JPG artifacts appear first around sharp edges and fine detail. Lower it only when file size matters more than fidelity.
