JPG to WEBP Converter

Convert JPG to WEBP for free in your browser. WEBP delivers the same visual quality at roughly 25–35% smaller file size, which makes it the better choice for images you serve from a website.

The size difference is real

WEBP's lossy mode uses prediction techniques borrowed from video compression, which JPEG — designed in 1992 — does not have. Across typical photographic content the saving is consistently 25–35% at matched visual quality.

On an image-heavy page that is the difference between a fast site and a slow one, and it applies on every single load.

This is a lossy-to-lossy transcode

Your JPG has already discarded information. Converting to WEBP decodes it and re-encodes with a different lossy codec, discarding a little more. At quality 85 or above this is not visible, but it is worth knowing:

• Convert from the highest-quality source you have, not from an already-compressed copy.
• Use quality 85 for the conversion — the gains from going lower are modest and the risk of visible artifacts rises sharply.
• Keep the JPG as a fallback for browsers and tools that need it.

Serving both

The `<picture>` element lets you offer WEBP with a JPG fallback — the browser picks the first source it understands. That gives you the size saving on modern clients without breaking anything on older ones.

How to convert

1. Drag your JPG file into the box above, or click to browse. Multiple files at once is fine.
2. Confirm WEBP is selected as the output format.
3. Adjust the quality slider if the format is lossy.
4. Click Convert, then download the WEBP files individually or as a single ZIP.

How much smaller is WEBP than JPG?

Typically 25–35% at equivalent visual quality. The exact figure depends on content — images with large smooth areas benefit most.

Will converting lose quality?

A small amount, since both formats are lossy and you are re-encoding. At quality 85 or above it is not perceptible. Always convert from the best source you have rather than from a copy.

Can I upload WEBP to an exam or government form?

No. Those portals require JPEG almost without exception. WEBP is for web publishing, not for form uploads.

Is AVIF better than WEBP?

For compression, yes — often another 20–30% smaller. Support is slightly narrower outside browsers and encoding is slower. Serving AVIF with a WEBP fallback is the current best practice.
