Convert JPG and PNG images to WebP — and convert WebP back to JPG or PNG — right in your browser. Batch support, quality control, and instant file-size savings. No upload, no watermark, no signup.
WebP is a modern image format from Google that delivers the same visual quality as JPG or PNG at a much smaller file size — usually 25–35% smaller than JPG. Smaller images mean faster page loads, better Core Web Vitals, and higher search rankings. This converter runs entirely in your browser, so nothing is uploaded.
Need to open a WebP in older software that doesn't support it? Drop your WebP files in and choose JPG or PNG as the output to convert them back. Transparency is preserved when converting to or from PNG and WebP.
Are my images uploaded?
No. Conversion runs in your browser via canvas. Files never leave your device.
How much smaller is WebP?
Typically 25–35% smaller than JPG at the same quality, often far smaller than PNG.
Can I convert WebP back?
Yes — choose JPG or PNG as the output to reverse the conversion.
Does WebP keep transparency?
Yes — transparent PNGs convert to transparent WebP.
