Viewing, inspecting and verifying. You get the full image on a zoomable canvas, with pixel dimensions read from the file header. File details, exact byte size and the detected signature are always shown.
How to open a .webp file
If double-clicking a WEBP file did nothing useful, that is normal: the format is fine, your operating system just has no default application registered for it. This page explains the format and gives you a way to read one immediately.
What is a .webp file?
WebP Image is an image format developed by Google, first appearing in 2010. It is normally produced by Chrome, modern CMS image pipelines.
A RIFF container wrapping VP8 (lossy) or VP8L (lossless) — one extension, two completely different codecs, plus optional animation and alpha.

Open a .webp file in your browser
OpenAnyFile routes .webp to its native image decoder, which renders the full image on a zoomable canvas, with pixel dimensions read from the file header.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .webp file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
- The extension is detected and the file is handed to the native image decoder.
- Your WEBP opens on its own viewer page: the full image on a zoomable canvas, with pixel dimensions read from the file header.
- Use fullscreen for a closer look, or download the file back out unchanged. Nothing is transmitted anywhere — the parsing happens in your own browser process.
What you can and cannot do with it here
Does not work
Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.
No upload, and here is why that matters for {E}
Handing a .webp file to a random conversion site means handing over a copy you cannot get back. OpenAnyFile parses the file locally instead — the same way special software reads it off your disk, except the reader happens to be a web page. Nothing is transmitted, so there is nothing to leak, log or subpoena. It also means it keeps working with your Wi-Fi switched off.
Frequently asked questions about WEBP files
Can I open a .webp file without installing special software?
Yes. OpenAnyFile's native image decoder runs in your browser, so you can read a WEBP file with nothing installed. You get the full image on a zoomable canvas, with pixel dimensions read from the file header. For full editing you still need the original application — this is a viewer, not an editor.
How can I check a file really is a WEBP file?
Look at the first bytes rather than the extension. A genuine WEBP begins with 52 49 46 46 .. 57 45 42 50. Opening the file in OpenAnyFile shows that signature in the file-details panel, so a file renamed to .webp by mistake is easy to spot.
Is it safe to open a WEBP file online?
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.
What is a .webp file, exactly?
WebP Image — an image/webp format created by Google since 2010. A RIFF container wrapping VP8 (lossy) or VP8L (lossless) — one extension, two completely different codecs, plus optional animation and alpha.
Does the same viewer handle formats related to WEBP?
Yes — the same engine also opens .gif, .jpeg, .jpg, so you can compare related files without switching tools.
