JPG to WebP converter
WebP typically produces smaller files than JPG at similar visual quality — a good choice for websites, portfolios, and anywhere load speed matters. If you have a folder of JPEG photos and want leaner assets without sending them to a cloud service, this tool converts them locally.
Everything runs in your browser using the Canvas API. Add your JPG files, select WebP as the output format, tune quality, and download. No upload, no account, no server in the middle — your images never leave your device.

FAQ
Why convert JPG to WebP?
WebP typically produces smaller files than JPG at similar visual quality, which helps websites load faster and saves storage space. It is a good choice when you need lean image assets for the web.
Does WebP work in all browsers?
WebP is supported in all major modern browsers including Chrome, Firefox, Safari, and Edge. If you need maximum compatibility with very old software, JPG may still be the safer choice.
Are my photos uploaded to a server?
No. This converter runs entirely in your browser. Your JPG files are decoded and re-encoded locally using the Canvas API — they never leave your device.
Can I adjust WebP quality?
Yes. Use the quality slider to balance file size and visual fidelity. Lower values produce smaller files; higher values preserve more detail.
