Convert JPG to WebP — Faster Web Images

WebP images load faster than JPEG with equivalent visual quality, saving bandwidth and improving Core Web Vitals scores. This converter handles EXIF orientation automatically — portrait photos shot on phones always come out right-side up. Convert your JPEGs to WebP in your browser, no upload required.

How to use this tool

  1. Upload JPEG images

    Drop JPG or JPEG files onto the converter. EXIF orientation data is automatically read and applied, so portrait iPhone photos come out correctly rotated.

  2. Set your quality level

    For most web images, 80–85% produces files that are visually equivalent to JPEG at 90%+ while being significantly smaller. Our default of 82% is a good starting point.

  3. Click Convert

    Your browser decodes each JPEG (applying orientation correction) then re-encodes to WebP using Google's libwebp encoder via WebAssembly.

  4. Replace your old JPG files

    Drop the converted WebP files directly into your website's image folder. All modern browsers support WebP. Use the <picture> element if you need JPG fallbacks for older browsers.

Frequently Asked Questions

How much bandwidth will I save by converting my JPEGs to WebP?

WebP achieves 25–35% better compression than JPEG at the same visual quality. For a website with 100 image requests at 200 KB average, switching to WebP can save 5–7 MB per page load. Google reports that the web serves over 30 trillion images monthly — the cumulative bandwidth savings from WebP adoption are enormous.

Is WebP better than JPEG in all cases?

For photographic content, WebP is better in almost all cases. The exception is extremely high-quality JPEG (95%+) where WebP's quality advantage shrinks. For images you plan to edit, both formats are lossy, so keep an uncompressed format (PNG or RAW) for editing. For the best compression of photos, also consider AVIF which outperforms WebP by another 20–30%.

Will my JPEG photos be right-side up in the WebP output?

Yes. Our engine reads the EXIF orientation tag from your JPEG and rotates/flips the pixel data accordingly before encoding to WebP. This is important because many JPEGs taken in portrait orientation on phones have an orientation tag of 6 (90° rotation), but some apps don't respect EXIF and display them sideways.

Does WebP support animated images?

Yes — WebP supports animation, like GIF but with far better compression and color quality. However, this converter is for static WebP (one frame). To create animated WebP from video, use a dedicated tool like FFmpeg.

Should I convert all my website images to WebP?

Yes, if browser support allows. Use a <picture> element with WebP as the primary source and JPEG as fallback. Better yet, configure your CDN (Cloudflare, AWS CloudFront) to automatically serve WebP when the browser supports it — then you don't need to maintain two sets of files.
