You right-click an image, hit "Save image as…," and instead of a familiar JPG or PNG you get a file ending in .webp — which your photo editor rejects, your CMS won't accept, or Photoshop’s older version refuses to open. If this keeps happening to you, you're not doing anything wrong. The web itself changed.
WebP is an image format Google introduced to make websites faster, and by 2026 it's what a huge share of sites actually serve. This article explains exactly why your downloads come out as WebP, whether you lose anything by converting, and three free ways to turn a WebP back into a PNG — including one that works on any device with a browser.
Why Are Images Saving as WebP?
WebP typically compresses images 25–35% smaller than an equivalent JPEG and dramatically smaller than PNG, while also supporting transparency and animation. Smaller images mean faster page loads, lower bandwidth bills, and better Core Web Vitals scores — so websites have overwhelming incentive to serve WebP.
Here's the key detail: many sites don't even store a WebP file. Their servers and CDNs detect that your browser supports WebP (every modern browser does) and convert images on the fly before sending them. The page's code might reference photo.jpg, but what actually arrives in Chrome is WebP — and "Save image as…" saves what arrived, not what the filename suggested. That's why the same image might save as JPG on an old browser and WebP on yours.
So the WebP downloads aren't a bug or a setting you broke. They're the modern web working as designed — it's just inconvenient when the software you paste images into hasn't caught up.
The Easiest Fix: Convert WebP to PNG in Your Browser
The most universal solution works on Windows, Mac, Linux, ChromeOS, and phones alike: a free online converter. Toolyfied's WebP to PNG converter converts the file right in your browser — free, no sign-up, no watermark, files up to 50 MB — and PNG output preserves any transparency the WebP contained.
- Step 1: Open the WebP to PNG tool in any browser.
- Step 2: Upload the .webp file you downloaded (or drag and drop it).
- Step 3: The tool converts it to a standard PNG in seconds.
- Step 4: Download the PNG and use it anywhere — every app on earth opens PNG.
Offline Fixes: Paint on Windows, Preview on Mac
On Windows 10 and 11, Microsoft Paint opens WebP natively. Open the file in Paint, choose File → Save As → PNG, and you're done. It's quick for a single image, though tedious if you have a folder full of them.
On a Mac, Preview does the same job: open the WebP, choose File → Export, and pick PNG from the format dropdown. Both routes are lossless in the sense that they decode the WebP exactly as your screen displays it and re-save those pixels as PNG.
A third trick worth knowing: some sites only serve WebP conditionally. Copying the image and pasting directly into your editor sometimes bypasses the file format question entirely, since the clipboard carries raw pixels rather than an encoded file.
Is PNG Better Quality Than WebP?
Not inherently — and this surprises people. PNG is always lossless, while WebP comes in both lossy and lossless flavors. A lossy WebP has already discarded some detail to hit its small file size, and converting it to PNG cannot bring that detail back. The PNG you get is a pixel-perfect copy of the WebP as it exists, wrapped in a more compatible container.
That's exactly why converting is safe: you lose nothing in the conversion itself. The reason to convert is compatibility, not quality — PNG opens in legacy design tools, government upload portals, old CMS platforms, email clients, and anything else that predates WebP support.
One caution for the other direction: if you're publishing images on your own website, don't convert your WebP files to PNG for upload. You'd be trading away the exact performance benefit the format exists for. Instead, keep formats web-friendly and shrink your files with a free Image Compressor so your pages load fast for everyone.
Can You Stop Chrome From Saving Images as WebP?
There's no Chrome setting for it, because the format decision is made by the website's server, not your browser. Extensions exist that rewrite the request to ask for JPEG or PNG, but they only work on sites that actually keep those alternate versions, and they slow down your browsing on every other site.
The pragmatic 2026 answer: let sites serve you WebP (your pages load faster for it), and keep a converter bookmarked for the handful of times a downloaded image needs to be a PNG. Two clicks in the WebP to PNG converter beats fighting the entire direction of the web.
