Instant browser-based conversion — no upload, no server, no account. WebP is 25–35% smaller than JPEG at the same visual quality.
Convert JPG to WebP Now →Drag your JPG or JPEG onto the upload area, or click to select. Supports batch conversion — up to 10 images at once. Your files never leave your browser.
Open Advanced Settings → set Format to WebP. For most web images, quality 80% gives the best size-to-quality ratio. Use 85–90% for photography, 70–75% for thumbnails.
Click Compress. ImgMin converts locally and offers the WebP file for download instantly. Batch conversions can be downloaded as a single ZIP file.
These figures are based on real-world image tests. Results vary by image content — photos with complex texture compress differently than flat graphics or illustrations.
| Image Type | JPG Size | WebP Size (q80) | Savings |
|---|---|---|---|
| Portrait photo (3MP) | 820 KB | 560 KB | 32% smaller |
| Landscape photo (4K) | 4.2 MB | 2.7 MB | 36% smaller |
| Product photo (white bg) | 290 KB | 180 KB | 38% smaller |
| Screenshot / UI | 450 KB | 310 KB | 31% smaller |
| Highly compressed JPG | 95 KB | 88 KB | 7% smaller |
💡 Already-compressed JPGs (under 100KB) show minimal WebP gains because they've already lost most compressible data. Convert original, high-quality source files for best results.
WebP is now supported across all modern browsers. The only exception is Internet Explorer, which accounts for less than 1% of global traffic.
| Browser | WebP Support | Since Version |
|---|---|---|
| Chrome | Full | v32 (2014) |
| Firefox | Full | v65 (2019) |
| Safari | Full | v14 (2020) |
| Edge | Full | v18 (2018) |
| iOS Safari | Full | iOS 14 (2020) |
| Android Chrome | Full | v32 (2014) |
| Internet Explorer | Not supported | — |
Best use case. Smaller files → faster page loads → better Core Web Vitals scores and lower bandwidth costs.
30–40% smaller product images load faster on mobile, directly improving add-to-cart conversion rates.
Upload WebP to avoid double-compression. Platforms that accept WebP (Twitter, Facebook) will recompress less aggressively.
Stick to JPEG or TIFF for print workflows. Most print services don't accept WebP, and some editing software has limited WebP support.
Outlook and most email clients don't render WebP inline. Use JPG for email images to ensure compatibility.
Converting a low-quality JPG to WebP degrades it further without meaningful size reduction. Always convert from high-quality originals.
No upload. No server. Your images stay in your browser. Convert up to 10 JPGs to WebP at once.
Start Converting Free →WebP is typically 25–35% smaller than JPEG at equivalent visual quality. Google's original research found 25–34% average file size reduction for lossy WebP vs JPEG at the same SSIM score. For a 1 MB JPEG, expect a 650–750 KB WebP at quality 80.
At quality 80% and above, the difference is imperceptible to the human eye under normal viewing conditions. WebP uses a more efficient compression algorithm, so it achieves better quality at the same file size — not worse quality. Only re-encoding an already-compressed JPG will degrade it.
Yes. Chrome, Firefox, Safari (since iOS 14 / macOS Big Sur), Edge, and all modern mobile browsers fully support WebP. Global support exceeds 97%. Internet Explorer is the only exception at under 1% global usage share.
With ImgMin — yes. All conversion happens in your browser using the Canvas API. Your images are never uploaded to any server. You can verify this by opening DevTools → Network tab while converting and seeing zero upload requests.
Yes, but with caveats. Converting WebP → JPG → WebP introduces cumulative quality loss from double-encoding. If you need the original JPG, always keep it before converting. ImgMin can also compress WebP files directly without converting formats.
