Convert JPG to WebP
If you're optimizing images for a website, WebP is the easiest win available: at comparable visual quality it's typically 25–35% smaller than JPG, which translates directly into faster page loads.
This converter runs in your browser with WebP preselected. Compare the size readout against your source and keep whichever wins — occasionally an already heavily compressed JPG won't shrink further, and the tool will show you that honestly.

How it works
Select one or more images.
Choose the target format; consequences (like losing transparency in JPEG) are shown before converting.
Pick a background color if converting transparency to JPEG.
Convert and download individually or as a ZIP.
What the tool does
- PNG, JPEG, and WebP output
- Batch conversion with per-file success/failure isolation
- Explicit background selection when alpha meets JPEG
- Quality control for lossy targets
- ZIP download with deterministic file naming
How the result is verified
Every output is re-decoded to confirm it parses as the target format with the expected dimensions; failures are isolated per file.
Frequently asked questions
How much smaller will my file get?
For typical photos, expect 25–35% savings at equivalent quality. The tool shows exact before/after byte counts measured from the real output, not an estimate.
Where can WebP be used safely?
All current browsers, chat apps, and most CMSes handle WebP. The stragglers are older desktop software and some strict upload forms — for those, stick with JPG.
