Convert Images to WebP

Q: Will my images be uploaded?

Never. All decoding and encoding for images to WebP runs inside your browser via WebAssembly. This site has no image upload endpoint at all, and it works offline.

Q: Is it free? Any limits on file count or size?

Completely free — no sign-up, no watermark. images to WebP has no file-count or per-file size limits. Since images are processed on your device, server costs are zero and this can stay free forever.

Q: Will quality drop?

Default quality is 85 (adjustable 0–100). WebP is lossy; repeated conversions accumulate artifacts, so convert once from the original.

Q: Does it support batch processing?

Yes. Drop dozens or even hundreds of images at once; the memory-budget scheduler processes them locally in a queue. Download individually or as a single ZIP.

Q: Is EXIF metadata or GPS kept in the output?

No, metadata is stripped by default. EXIF and GPS data are removed from the output, so shared files never leak where photos were taken — a privacy feature by itself.

Whatever you have — PNG, JPG, HEIC or AVIF — drop it in and get WebP out: supported everywhere modern, smaller, with alpha. The universal answer for web pages and mini-programs.
