Convert WebP to JPG Online — Free, 100% Local
100% local processing. The tool runs entirely inside your browser — nothing is uploaded to any server.
WebP has become the default image format that Chrome, Edge and many major sites (Google Images, Pinterest, most modern e-commerce sites) serve to save bandwidth. The catch: when you right-click and 'save image as', you get a .webp file that a lot of older apps, presentation software, print pipelines, older Photoshop versions, government upload forms and legacy CMS platforms refuse to open. Converting WebP to JPG makes the file work everywhere. This page explains how to do that conversion in the browser using ImageMarker's local-only converter, without uploading the file anywhere.
The mechanics: drop a WebP file on the tool, the browser's Canvas API decodes it (WebP support is built into every modern browser) and re-encodes as JPG at your chosen quality level. Default is 90%, which is visually indistinguishable from the source at normal viewing. The output downloads immediately — no upload, no queue, no server round-trip. Batch mode handles a folder of WebP files in one operation, which is common when you have downloaded a set of product photos or reference images from a WebP-serving site.
One thing to note about size. WebP is roughly 25-35% smaller than JPG at the same visible quality, so the converted JPG is usually larger than the source WebP. This is fine when the destination requires JPG — you are trading a smaller file for compatibility, and the destination is where compatibility matters. If you need the smallest possible file and the destination accepts WebP, keep it as WebP. If you specifically need the JPG version smaller, use the compressor's quality slider after conversion to trim the size down.
Transparency, when present, gets flattened to a background color (white by default) because JPG has no alpha channel. This matters for logos or design assets saved as transparent WebP — you either fill with a matching background color or convert to PNG instead. For photographs, the transparency question doesn't come up. As with the other converters here, the entire pipeline runs locally: the WebP never leaves your browser tab, which matters for any file that isn't strictly public.

Frequently asked questions
Why do images from Google Images download as WebP?
Chrome and Edge automatically request WebP versions from sites that offer them, because WebP files are 25-35% smaller than JPG at the same quality. Google Images, Pinterest and most modern CDNs serve WebP by default to Chrome. When you save one, you get the .webp file, which some apps cannot open.
Is my WebP uploaded to a server?
No. ImageMarker uses the browser's built-in WebP decoder and Canvas re-encoder to convert entirely on your device. The source file never leaves your browser tab, which is unusual — many 'free WebP to JPG' converters online run the decode step server-side.
Will the JPG be smaller or larger than the WebP?
Usually slightly larger, because WebP compresses more efficiently than JPG at the same visual quality. If the destination requires JPG (a form, an older app, print output), that is the trade you make — a larger file for compatibility. The compressor's quality slider can then shrink the JPG further.
Does the conversion lose visible quality?
At 85-90% JPG output, the visible difference is essentially zero at normal viewing. WebP is already lossy in most cases, so the re-encode step just re-quantizes the pixels once more; the visible result stays clean.
Can I batch convert a folder of WebP files?
Yes. Select multiple WebP files and the tool processes them locally in one operation, then packages the JPGs together for download. Batch throughput is limited by device memory rather than by the tool.
What happens to transparency in the WebP?
JPG has no alpha channel, so transparent pixels are filled with a background color (white by default). If you need transparency preserved, convert to PNG instead — PNG supports transparency and is universally supported by every app that opens WebP's transparency version.
