Why you keep ending up with WebP files
WebP is an image format from Google that most websites now serve because it is smaller than JPG or PNG at the same visual quality. When you right-click an image in Chrome, Edge or Firefox and choose Save image as, you often get a .webp file even if the site originally uploaded a PNG — the server picked WebP because your browser said it could display it.
The file looks fine in the browser, but then an older photo editor refuses it, a print shop's upload form rejects it, or a slide program shows a blank box. Converting to PNG fixes that: PNG has been supported by practically every program for decades.
What this converter does with your file
- Drop one or several
.webpfiles into the box above. - Each image is decoded by your browser and re-encoded as a PNG on your device — nothing is uploaded.
- Download a single PNG, or all of them in one ZIP when you convert a batch.
Transparency is kept. If the WebP has a transparent background — a logo, a sticker, a product cut-out — the PNG keeps the same alpha channel, pixel for pixel. Nothing is filled with white or black. If you want a white background instead, convert WebP to JPG.
The dimensions stay the same, with one exception: images above roughly 16.7 megapixels are scaled down to fit the browser's canvas limit (iPhone Safari is the strictest), and the page tells you when that happens.
Animated WebP
WebP can hold an animation, like a GIF. PNG as produced here cannot, so you get the first frame only as a still picture. If you need the motion, keep the original WebP or use a video/GIF tool; if you just needed a thumbnail or a sticker preview, the first frame is usually what you want.
PNG or JPG — which should you pick?
| Choose PNG when | Choose JPG when |
|---|---|
| The image has transparency | It's a photo with no transparency |
| It's a logo, icon, screenshot or text-heavy graphic | File size matters (email, upload limits) |
| You will keep editing it | You just need it to open everywhere |
A photo saved as WebP and converted to PNG can come out several times larger than the WebP. That's normal: PNG is lossless, so it stores every pixel exactly, including the fine noise in a photograph. It does not bring back detail that lossy WebP compression already removed — it just stops any further loss.
Opening WebP without converting
- Windows 10/11: the Photos app and Paint open WebP; older Photoshop versions and some Office builds don't.
- Mac: Preview opens WebP on macOS Big Sur and later, and File → Export can save as PNG — handy for one file, slower for twenty.
- Phones: Android and iOS galleries display WebP, but many apps that ask for "a photo" only accept JPG or PNG. Converting in the phone browser here works the same as on desktop.
After converting
- PNG too heavy? Run it through Compress Image, or switch to WebP to JPG if transparency isn't needed.
- Need the background gone? Use Remove Background on the PNG.
- Need a different size? Resize Image keeps the format.
- Going the other way for your own website? PNG to WebP makes files smaller for faster pages.
- Other formats (AVIF, HEIC, GIF)? Try the general image converter.
