Open .WEBP files online
A .webp file is an image in WebP, a modern format introduced by Google in 2010 that supports both lossy and lossless compression, transparency, and animation. WebP files are typically much smaller than equivalent JPEG or PNG files, which is why it has become a default web image format.
WebP is now supported by all major browsers, so it can replace JPEG (for photos), PNG (for lossless graphics and transparency), and GIF (for animation) with a single, more efficient format.
What is a `.webp` file?
WebP is based on the VP8 (lossy) and VP8L (lossless) codecs originally developed for video. A single .webp can be lossy or lossless, can include an alpha channel for transparency, and can hold multiple frames for animation.
MIME type: image/webp. Because it beats older formats on size for comparable quality, most CDNs and build tools now auto-convert images to WebP for delivery.
- Web images optimized for faster page loads
- Photographs (lossy WebP replaces JPEG)
- Graphics with transparency (lossless WebP replaces PNG)
- Animations (animated WebP replaces GIF)
How to open a `.webp` online
Open the zip viewer in a new tab, then drop your .webp onto the page — or click to browse for it, or paste a URL. The file opens in the image viewer, read entirely on your device.
- Drag your
.webponto the page — or click to browse, or paste a URL. - It opens immediately in the image viewer. No install, no sign-up.
- Read, search, or copy it. Your file never leaves your browser.
Open `.webp` without uploading
Most "open webp online" sites work by uploading your file to a server and processing it there. ZipTool does the opposite: it loads its parser once, then reads your .webp locally in the browser tab. The contents stay on your device.
You can prove that in seconds. Open the page, press F12 for DevTools, switch to the Network tab, and open your file — no request carrying the file's contents is sent. You can also turn off Wi-Fi after the page loads and the file still opens. See security and privacy for the full picture.
Frequently asked questions
How do I open a .webp online?
Drag the .webp onto the page (or click to browse, or paste a URL). It opens in the image viewer immediately. The file is decoded entirely in your browser and never uploaded.
Can I view a .webp without uploading it?
Yes. ZipTool decodes the image locally in your browser tab — no upload, no server-side copy. Confirm it with DevTools (F12, Network tab) while opening the file, or by disabling Wi-Fi after the page loads and verifying the image still displays.
Is WebP better than JPEG and PNG?
For most web uses, yes: lossy WebP is typically 25-35% smaller than JPEG at similar quality, and lossless WebP is smaller than PNG while also supporting transparency and animation. The main historical caveat — older browser support — is no longer an issue in modern browsers.
Can a WebP be animated?
Yes. Animated WebP sequences frames like an animated GIF but at far smaller file sizes and with full color, making it a modern replacement for GIF animations.
