JPG to WebP Converter

WebP stores a photograph in appreciably less space than JPEG at the same visible quality, which is why almost every fast website has moved to it. This converts your JPGs in the browser, with each result measured against the original rather than saved at a number somebody guessed.

How it works

Three steps to a WebP

  1. 1

    Add your JPG files

    Drag them in, paste from your clipboard, or tap to browse. A whole folder at once is fine.

  2. 2

    Check the settings

    Quality is matched to your original automatically. Set it by hand instead if you have been given a number to hit.

  3. 3

    Download

    Save your WebP files. Nothing was sent anywhere, so there is nothing to delete afterwards.

Why this one

Why convert JPG to WebP here

A newer encoder, doing the same job better

JPEG's design is from 1992 and it has aged well, but WebP simply has better tools: smarter prediction, a more modern entropy coder, and no legacy baggage to preserve. On the same photograph at the same visible quality it usually needs meaningfully fewer bytes. Nothing about the picture changes — only how efficiently it is stored.

  • 02

    It is a second lossy save

    Your JPG already had detail thrown away once. Converting to WebP throws a little more away, because both formats are lossy. It is a small effect and this tool keeps it small by measuring each result against what you gave it — but converting the same file back and forth repeatedly is a bad idea in any format.

  • 03

    Nothing is uploaded

    Your JPG files are read and written inside your own browser. Nothing is sent to us, which is why there is no size cap beyond what your device can hold and no queue to wait in.

  • 04

    A whole folder at once

    Drop in as many JPG files as you like. Each one is converted separately and gets its own result, so one awkward file cannot spoil the rest of the batch.

  • 05

    It shows you the real numbers

    Every file reports what it weighed before and after, and which way it moved. Where another format would have come out meaningfully smaller than WebP, that is offered next to the file instead of being quietly withheld.

Who it's for

When you'd use it

  • Someone with a slow product page

    A shop page carrying twenty photographs is mostly image bytes. Converting them is usually the biggest speed win available, and nothing about the layout has to change.

  • Someone with a folder of them

    A batch that all needs to be WebP before it goes anywhere — dropped in together rather than converted one at a time.

  • Someone on a work laptop

    Software installs are blocked and the files are not theirs to upload to a stranger's server. A browser tab is the only tool available, and it is enough.
