How to open a .wdp file
OpenAnyFile routes .wdp files to its image decoder, which shows the picture if your browser has this codec, otherwise a full inspection of the file.
- Drop your .wdp file on the box above, click it to choose the file, or paste it with Ctrl+V.
- The real format is detected from the file's first bytes — not just its name.
- The file opens in the image decoder.
- Use fullscreen for a closer look, check its checksums, or download it back unchanged.
What works — and what does not
Works
Viewing and inspecting: the picture if your browser has this codec, otherwise a full inspection of the file. Size, type, signature and checksums are always shown.
Does not work
Guaranteed playback. It depends on your browser shipping this codec; if it doesn't, you still get the full inspection.
Is it safe to open a .wdp file online?
Here, yes — because nothing is uploaded. Most "online viewers" send your file to their server. OpenAnyFile reads it with your browser's File API and decodes it on your own device, so there is no copy anywhere else. You can check: open your browser's network tab while opening a file — no upload appears.
Questions about .wdp files
Can I open a .wdp file without installing software?
Yes. OpenAnyFile opens .wdp files in your browser using its image decoder. You get the picture if your browser has this codec, otherwise a full inspection of the file, with nothing installed and no account.
How do I know a file is really a .wdp file?
Check its first bytes instead of its name. A genuine WDP file begins with 49 49 BC 01. OpenAnyFile shows the detected type, so a renamed file is easy to spot.
Is my .wdp file uploaded anywhere?
No. The file is read locally by your browser and never sent to a server — it even works offline once the page has loaded.
Does it work on phones?
Yes — on Android and iPhone, in any modern browser. You can also install OpenAnyFile as an app.
