Convert JPG and PNG to WebP for smaller, faster images, or convert WebP back to PNG or JPG. Everything runs in your browser.
How it works
Drop in your images, choose the target format (WebP, PNG, or JPG) and a quality, and each file is re-encoded in your browser with its before/after size shown. Converting to WebP usually cuts file size noticeably with no visible quality loss at sensible settings.
Everything runs locally. Your images are never uploaded, and there is no signup.
Frequently asked questions
What is WebP and why convert to it?
WebP is a modern image format from Google that typically produces files 25-35% smaller than JPG or PNG at similar quality. Smaller images mean faster pages, which helps both visitors and SEO. Every current browser supports WebP.
How do I convert an image to WebP?
Drop in your JPG or PNG files, leave the format on WebP, set a quality, and download. Each file is converted in your browser and shows the size saved.
Can I convert WebP back to PNG or JPG?
Yes. Drop in your WebP files and choose PNG or JPG as the output format. PNG keeps transparency; JPG is best for photos and flattens transparency onto white.
Does converting lose quality?
WebP and JPG are lossy, so very low quality settings soften detail. Around 80% is a good balance. Converting to PNG is lossless. Converting a lossy file to another lossy format always recompresses, so avoid repeated round-trips.
Can I convert several images at once?
Yes. Add multiple files and they all convert with the same settings, each with its own download button plus a Download all option.
Are my images uploaded?
No. Conversion happens entirely in your browser, so your images never leave your device. There is no signup and no practical file limit beyond your browser.
