Convert JPG to WebP and see the size difference
Re-encode JPG photos as WebP, choose a quality, and see how the new size compares with the original JPG. Because JPG is already lossy, expect modest savings at best.

How to use it
- Add your JPG files.
- Set the WebP quality.
- Decide whether to keep metadata.
- Convert, check the size comparison, and download.
What it keeps
- Pixel dimensions.
- Overall appearance at sensible quality settings.
What it removes or changes
- The JPG is decoded to pixels and encoded again as WebP. This is a second lossy generation, and JPG artefacts already in the image are kept and can be re-compressed.
- The WebP may be smaller or, for already-small JPGs, not smaller at all.
- Metadata is dropped unless you keep it.
Limits
- Converting cannot restore detail lost when the JPG was made.
- A JPG has no transparency, so the WebP will not have any either.
- Not every old program opens WebP.
Compatibility
Current browsers display WebP, and most modern CMSs accept it. Older desktop software, some email clients and many government or print upload forms do not. Keep the JPG for those cases.
Privacy
Encoding runs in your browser. Your images are not uploaded.
Is switching from JPG to WebP worth it?
For a website you control, usually yes: WebP often gives smaller files at similar looks. For files other people open, no: JPG works everywhere. If you still have the original camera file or a higher-quality source, convert from that instead of from a JPG, to avoid stacking one lossy step on another.
Troubleshooting
The WebP is larger than the JPG.
The JPG was already compact. Lower the quality or keep the JPG.
The WebP looks blotchy.
Raise the quality. Re-compression compounds earlier artefacts.
A site rejects the WebP.
Send or upload the original JPG instead. WebP is not accepted everywhere.
Frequently asked questions
Will quality drop?
Slightly, since it is a second lossy encode.
Is it always smaller?
No. The size comparison tells you.
Can I keep the EXIF?
Yes. Date, camera and settings can be kept as an option. Location needs its own explicit choice.
