JPG to WebP Converter
WebP is the modern image format the web runs on: the same picture typically comes out 25–35% smaller than JPG at comparable quality, it supports true transparency, and every current browser renders it natively.
How to use
- Click the upload area or drop a JPG file into it.
- The WebP file is generated immediately — compare the output size in the result panel.
- Click download to save the WebP, or press Start over for the next image.
Frequently asked questions
How much smaller is WebP than JPG?
For photographs, WebP typically saves 25–35% of the file size at visually equivalent quality, and even more for graphics with flat colors. The exact saving for your file is shown in the result panel.
Can WebP replace JPG everywhere?
All current versions of Chrome, Edge, Firefox and Safari display WebP natively. Very old software and some offline tools may still require JPG, so keep the original until you have confirmed your target platform.
Does converting happen on a server?
No. The conversion runs entirely in your browser via the canvas API. Your file never leaves your device — nothing is uploaded, stored or logged.
What if my browser cannot encode WebP?
The page detects this before you start, shows a bilingual notice, and blocks the conversion instead of producing a broken file. It suggests converting to PNG as a fallback route.

About this tool
WebP is the modern image format the web runs on: the same picture typically comes out 25–35% smaller than JPG at comparable quality, it supports true transparency, and every current browser renders it natively. This converter turns your JPG files into WebP in one drop — no software, no queue, no account. It is the fastest way to slim down blog images, store product shots or app assets before uploading them to a site or CMS. Conversion happens entirely inside your browser on your own device: your images are read from disk, converted in memory and handed straight back, never touching a server, so sensitive or licensed material never leaves your machine. If your browser happens to lack WebP encoding support, the page tells you clearly and suggests the JPG to PNG route instead — no silent failures, no broken downloads. Preview the result, check the size saving, and download with one click.
