Features & benefits

  • Smaller files

    WebP files are typically 25–35% smaller than equivalent JPEGs, reducing bandwidth and page weight.

  • Side-by-side savings

    See the original and converted file sizes before you download.

  • Accepts PNG too

    Convert PNG graphics as well; WebP even supports transparency.

  • SEO friendly

    Lighter images help pages load faster, which supports better search rankings.

Is WebP right for you?

All modern browsers — Chrome, Edge, Firefox, Safari and their mobile versions — display WebP images, so it is a safe default for websites. WordPress, Shopify and most other platforms accept WebP uploads.

WebP is less widely supported by older desktop software and some print services. Keep your original JPEG for archiving and printing, and use the WebP copy online.

Frequently asked questions

Do all browsers support WebP?

Every current major browser supports WebP. Only very old versions such as Internet Explorer cannot display it.

Why is my WebP bigger than the JPEG?

If the original JPEG was already heavily compressed, re-encoding at a high quality can increase size. Lower the quality slider a little and convert again.

Can I convert WebP back to JPG or PNG?

Yes — use our WebP to PNG converter, then the PNG to JPG converter if you need a JPEG.
