Put your .webp files in the converter above and you get PNGs back, the same size in pixels by default, that open in the apps and upload forms that turn WebP away. It handles one image or a folder's worth at a time and bundles the results in a ZIP. The conversion runs entirely in your browser, so it's free and nothing is uploaded, and JPG is one click away if you'd rather have smaller files.
Why so many images are WebP now
WebP is Google's image format, announced in 2010 to make pictures on the web smaller. Google's own figures put lossless WebP files 26% smaller than PNGs, and lossy ones 25–34% smaller than comparable JPEGs. Smaller images make pages load faster, so sites have good reason to switch:
- Speed tools ask for it. Lighthouse, Google's page-speed report, flags JPEG and PNG images and estimates how much smaller a modern format such as WebP or AVIF would make them.
- Website platforms do it for you. Many platforms have plugins that create a WebP copy of every image a site owner uploads.
- Your browser says it can take one. Browsers tell a server which image formats they accept, and a server can send WebP to browsers that accept it and JPG or PNG to the rest. That's how a picture saved with a right-click can arrive as a .webp even when the site also keeps it as a JPG.
Why an app won't open a WebP
WebP is younger than JPG and PNG, and support outside browsers is patchier. Every major browser displays it now, though Safari added it only in 2020, with version 14. Plenty of other software and many web forms still expect the older formats. YouTube's channel picture uploader, for one, lists JPG, GIF, BMP or PNG. Google's own WebP FAQ suggests the same fix this page offers: to view a WebP in any image viewer, convert it to a lossless format such as PNG. For how the three formats compare, see PNG vs JPG.
PNG or JPG: which to choose
| What's in the WebP | Convert to | Why |
|---|---|---|
| A logo, icon, sticker or cutout with a transparent background | PNG | Keeps the transparency, soft edges included |
| A screenshot, chart or anything with text | PNG | No new compression blur around letters and lines |
| A photo you'll send, post or print | JPG | Far smaller file; transparency doesn't matter |
| An image you'll keep editing | PNG | Lossless, so each save loses nothing |
With JPG selected, a quality slider appears, from 50 to 100% and starting at 92%, along with a choice of white or black for any transparent areas, since a JPG has nowhere to store transparency. Match the fill to where the picture is going: white for a document or a light web page, black for a dark design. PNG output has no lossy quality setting. Keep original size preserves decoded pixels within browser memory limits; optional resizing changes those pixels.
Expect a bigger PNG
WebP was designed to be small. Google says a lossy WebP with transparency typically comes out at a third of the size of the same image as a PNG. So when the converter decodes a WebP and stores every pixel exactly in a PNG, the file grows, often by a lot; it's the same effect you see when you convert a JPG to PNG. Each row in the list shows the size before and after.
For a logo or a screenshot the extra size is worth it. For a photo, where file size matters more than perfect pixels, the JPG option usually gives a much smaller file, with a quality setting you control, so if the new file is too big, try JPG before anything else.
Converting a batch
Saved a whole page of images? Add them all at once. Each is converted as soon as the one before it finishes, and banner.webp comes out as banner.png. You can change your mind halfway: switch Convert to from PNG to JPG, or move the quality slider, and the converter redoes every file in the list with the new setting. The Download all button then packs the results into one ZIP, and Clear the list empties it for the next batch.
The same list takes other formats too, including JPG, PNG, AVIF, BMP, GIFs (GIF to PNG also saves every frame of an animation), and iPhone photos; for those, the HEIC to JPG converter explains what changes. To turn a PNG into a JPG instead, see PNG to JPG. An animated WebP keeps its movement as a GIF with WebP to GIF, or as an animated PNG with the GIF to APNG converter, which reads animated WebP too. To turn a WebP logo into shapes instead of pixels, WebP to SVG traces it into a vector file.
Remove the background from a WebP
When the background is the problem rather than the format, you don't need to convert first: the background remover opens WebP files directly, cuts out the subject and saves a transparent PNG or WebP. Here, each converted file also has a Remove background button. It opens a local AI editor below the converted files, where a model on your device cuts out the subject and saves a transparent PNG. The separate main photo editor makes its free cutouts online from a reduced copy, which is usually quicker on phones.
When the dimensions need changing too
Use Crop, resize and file size to reduce a WebP's dimensions while converting it. A width setting calculates the height automatically; Fit inside a box handles a batch with mixed proportions. The image resizer gives concrete examples. PNG output still preserves transparency after resizing. If the receiving app supports WebP and the goal is a smaller file, keep WebP and use the quality control or an optional KB target instead. The image compressor explains these choices, and Preview shows the result you will actually download.
Frequently asked questions
Does the PNG keep the WebP's transparent background?
Yes. Pixels that are transparent or partly transparent in the WebP stay that way in the PNG, so a logo or icon still sits cleanly on any color. Only a JPG, which can't store transparency, gets a white or black fill.
Can I make a WebP file smaller instead?
Yes. Choose WebP under Convert to and lower the quality slider, and each file is saved again as a lighter WebP, with its new size shown in the list. If your browser can't save WebP files, the list says so, and PNG or JPG still work.
Will converting to PNG make the picture sharper?
No. The PNG stores the WebP's pixels exactly as they are, so any blur or blockiness from the WebP's compression stays. For a sharper picture you need a larger or less compressed original.
Can I convert an animated WebP?
As a PNG, JPG or WebP you get its first frame, and the row also offers every frame as separate PNGs. To keep the movement, convert it to GIF with the WebP to GIF converter; Chrome, Edge and Firefox keep every frame.
Can I use images I saved from a website?
Converting a file doesn't change who owns it. A picture saved from someone else's site still belongs to its owner, so check that you're allowed to reuse it, for example because the owner gave permission or the image's license allows it.
Are my WebP files uploaded to convert them?
No. Each file is decoded and saved as a PNG by your browser, right on your computer or phone, and the page never sends the images anywhere.
