WebP is Google's modern image format that delivers the same visual quality as JPG and PNG at dramatically smaller file sizes — typically 25–35% smaller than JPG and up to 30% smaller than PNG. Smaller images mean faster websites, lower bandwidth bills and better Core Web Vitals scores. This free WebP converter runs entirely in your browser: your images are never uploaded to any server, so conversion is instant and completely private.
Stay on the Image → WebP tab, drop in one or more JPG, PNG, GIF or BMP files, then drag the quality slider to balance file size against visual fidelity — 80–90% looks identical to the original for most photos. Click Download for a single image or Download All (ZIP) for the whole batch. To go the other way, switch to the WebP → JPG / PNG tab, upload your .webp files, pick the output format and download.
• Convert JPG, PNG, GIF & BMP to WebP with adjustable quality (10–100%)
• Convert WebP back to JPG or PNG in one click
• Batch conversion with per-file download and ZIP export
• Live size-savings stats and before / after preview
• Transparency preserved when converting PNG to WebP
• No upload required — fully client-side & private, works on any device
What is WebP?
WebP is an image format developed by Google that uses both lossy and lossless compression. It produces files 25–35% smaller than equivalent-quality JPGs, supports transparency like PNG, and even animation like GIF — making it the best all-round format for the web.
Will converting JPG to WebP reduce image quality?
WebP uses smarter compression, so at the default 85% quality the result is visually identical to the original JPG while being much smaller. Drop below 70% and you may start noticing artefacts in smooth gradients; stay at 80–90% for photos.
Does WebP support transparency?
Yes. Unlike JPG, WebP supports an alpha channel just like PNG — transparent areas of a PNG stay transparent after conversion, and the file gets smaller too.
Can I convert WebP back to JPG or PNG?
Yes — switch to the "WebP → JPG / PNG" tab above. Choose JPG for the smallest files (note: JPG cannot store transparency, so transparent areas become white) or PNG for a lossless result.
Are my images uploaded anywhere?
No. All conversion happens locally in your browser using the Canvas API. Your files never leave your device, so it's safe for private or sensitive images.
Which browsers support WebP?
All modern browsers — Chrome, Edge, Firefox, Safari (14+) and Opera — display WebP natively, covering over 97% of web users. That's why Google recommends it for site speed.
