Convert WebP to JPEG in your browser

Convert WebP files to JPEG in your browser. WebP is a modern image format from Google that combines efficient compression with broad browser support. It can deliver smaller files than JPEG or PNG for many visuals, making it a strong default for performance-focused publishing. JPEG is the classic photographic format for the web. It uses lossy compression to keep files small while preserving smooth color transitions, which makes it ideal for camera photos, product shots and other imagery with many gradients. Local Optimizer keeps the process local, fast and private with no uploads.

Frequently asked questions

Why use a local image compressor?⌄

Which formats are supported?⌄

Local Optimizer accepts JPEG, PNG and WebP images as input, as well as SVG vector files. Images can be converted to JPEG, PNG or WebP with a quality setting from 10% to 100%. SVG files are minified: comments, editor metadata and unnecessary whitespace are removed without changing the visual output.

Does compression degrade my images?⌄

JPEG and WebP use lossy compression: the lower the quality you pick, the smaller the file, at the cost of visual detail. A quality of 75–85% usually offers an excellent trade-off that is often imperceptible to the naked eye. PNG remains lossless. Try several settings: the comparison table instantly shows how much space you saved.

Is there a limit on file size or count?⌄

No server-imposed limits, because there is no server! The only limit is your device's memory. You can process several files at once and download them individually or as a single ZIP archive.
