Steps
- Open /tools/jpg-to-webp.
- Choose a .jpg or .jpeg file within the 25 MB and 8,192 px limits.
- Adjust WebP quality if needed (default 90%).
- Select Convert & download and save the .webp.
Browser WebP encoding is required
The tool checks canvas WebP encoding support before creating a download. If encoding is unavailable, you see a clear compatibility error. It never saves a PNG or JPEG mislabeled as WebP.
Quality versus restored detail
Raising WebP quality keeps more of the decoded pixels, but it cannot restore detail JPEG already discarded. Dimensions stay the same.
