How to use WebP Viewer
- 1. Open your WebP file. Drop or browse for the .webp image you want to inspect, whether it is a downloaded asset or a file whose format you are not sure your default viewer supports.
- 2. Review the rendered preview. The tool decodes the file and displays it at full quality alongside its pixel dimensions, letting you confirm the image looks right and check exactly how large it is.
- 3. Download the file if you need it elsewhere. Save a copy of the WebP straight from the viewer once you have confirmed it opens correctly, useful when your operating system does not natively preview the format.
When to use WebP Viewer
WebP Viewer opens and displays a WebP image directly in the browser, along with its pixel dimensions, for situations where your operating system or a messaging app will not render the format natively. Use it as a quick way to confirm a WebP file actually opens and looks the way you expect.
- Checking a file before sending it. A colleague asks you to confirm a WebP export looks correct before you send it along, but your file manager shows only a generic icon instead of a thumbnail.
- Opening a WebP on an older system. An older photo viewer or operating system does not support the WebP format, so double-clicking the file does nothing useful. Loading it here shows the image immediately.
- Verifying a download completed correctly. A WebP downloaded from a site looks suspicious in size or seems corrupted. Opening it in the viewer confirms whether it renders properly and reports its real dimensions.
- Previewing an asset from a design handoff. A design team shared a batch of WebP assets in a zip file and you want to quickly check each one's dimensions without importing them into a full editing tool.

About the WebP Viewer tool
WebP Viewer runs as plain JavaScript in your browser tab, with no server behind it. Open and view a WebP. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's WebP Tools section, 57 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. 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.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does WebP Viewer cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Are my files uploaded to a server?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
Which files does WebP Viewer accept?
It accepts WebP images. There is no file size cap imposed by a server; very large files are limited only by your device's memory.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I save the output?
Click the Download button once the result is ready. The file is built in your browser's memory and handed straight to your downloads folder, without passing through a server.
