JPG to WebP

Why convert JPG to WebP?

WebP is Google's image format for the web. For photos it typically produces files 25–35% smaller than JPEG at the same visual quality, and browsers have supported it everywhere since 2020 (Chrome, Edge, Firefox, Safari 14+, and all mobile browsers).

What you get

• Smaller files, same look — the quality slider (default 0.90) controls the trade-off; 0.80–0.85 is a good balance for large photo libraries.
• Batch conversion — drop a whole folder worth of JPGs and download each result.
• Before/after size and total savings — see exactly how much bandwidth you saved.
• Originals untouched — nothing is uploaded, so your photos stay on your machine.

Where WebP pays off

• Blog and shop images where LCP and mobile data matter
• Reducing storage for large photo libraries
• Serving responsive images (`<picture>` with JPEG fallback)

Notes and limits

• Convert to PNG instead if you need an alpha channel? Not here — WebP also supports transparency, but this tool reads JPG input which has none.
• Already-compressed JPG pixels cannot be recovered; WebP re-encodes what is there, it does not add detail.
• Max 30 MB per file, processed locally with the Canvas API.

FAQ

Is WebP smaller than JPG?

For photos, yes — typically 25–35% smaller at matched visual quality. Savings vary with image content and chosen quality.

Which quality should I pick?

0.90 keeps photos looking identical to the eye. Use 0.80–0.85 for big galleries or web pages where a few KB matter; use 1.0 only if you plan to re-edit the file.

Can I convert many files at once?

Yes. Select or drop multiple JPG files; each is converted in order and listed with its own download link.
