How to use Compress WebP
- 1. Load the WebP to shrink. Drop or browse for the WebP file you want to make smaller. The tool measures its original size right away so it can report the savings afterward.
- 2. Set the Quality. Drag Quality (%) down to trade some visual fidelity for a smaller file. A range around 60 to 75% often shrinks a photo noticeably while still looking sharp at normal viewing sizes.
- 3. Download the compressed WebP. Download the result, shown alongside the input size, output size and percent saved. Use those figures to confirm the compression actually met your size target.
When to use Compress WebP
Compress WebP re-encodes an image at a lower quality specifically to cut its file size, and reports exactly how much space was saved. It is for the practical task of making an image lighter to load or transfer.
- Fitting under an upload size limit. A form or CMS caps uploads at a fixed number of megabytes, and compressing an oversized WebP before submitting gets it under the limit without cropping the image.
- Speeding up a slow-loading page. A page audit flags a hero image as the largest asset on the page, so compressing it before the next deploy trims load time for visitors on slower connections.
- Preparing images for email. An email newsletter platform charges by total attachment size, and compressing each embedded WebP keeps a batch of product photos under the sending limit.
Examples

Input

About the Compress WebP tool
Compress WebP does its work locally, right in the browser. Re-encode a WebP at lower quality to cut its file size. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the WebP Tools collection on EditSafely, a set of 57 small, focused WebP utilities that share the same instant, private workspace.
You can shape the output with the Quality (%) setting, and the result refreshes the moment you change it. The finished file is put together in browser memory and saved with the Download button, so it never touches a server on the way to your disk. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
