What Is a WebP File and How Do You Open or Convert It?
You saved an image from a website, double-clicked it, and your photo editor or an older app threw up its hands: it can't open a .webp file. You're not doing anything wrong, and the file isn't broken. WebP is a real, modern image format that's everywhere on the web right now, but plenty of desktop software, email clients, and design tools still don't recognize it. The good news is that opening or converting a WebP file takes seconds, and you almost never need to install anything.
This guide explains exactly what a WebP file is, why so many images you download turn out to be WebP, and the fastest ways to view or convert one. We'll cover the built-in tools on Windows and Mac, how to open WebP in Photoshop and other editors, and how to convert WebP to a universal format like JPG or PNG entirely in your browser, with no uploads and no signup.
If you just want the image in a format that works everywhere, skip to the conversion section. If you want to understand the format so you can decide whether to keep it, start at the top.
What a WebP file actually is
WebP (the file extension is .webp) is an image format developed by Google in 2010 specifically to make web images smaller and pages faster. It was derived from the VP8 video codec, and it packs everything into a single container based on the RIFF format, the same general structure used by WAV and AVI files. In plain terms: it's a photo or graphic, just compressed with a newer, more efficient method than the JPG and PNG formats most people grew up with.
The reason websites love WebP is size. A lossy WebP image is typically 25 to 35 percent smaller than the equivalent JPG at the same visual quality, and lossless WebP averages about 26 percent smaller than PNG. WebP also pulls off a trick neither JPG nor PNG can do alone: it supports transparency (an alpha channel, like PNG) and animation (like GIF) while still compressing efficiently. That versatility is exactly why content management systems, e-commerce platforms, and image CDNs now serve WebP by default.
The catch is compatibility. Every modern web browser, including Chrome, Firefox, Safari, and Edge, has supported WebP since roughly 2023, so the file opens fine inside a browser. But outside the browser, the picture is patchier: many native operating-system tools, email clients, older editors, and print workflows still don't read WebP. That gap is the single reason you're reading this page.
Why the image you downloaded is a WebP
If you right-clicked an image on a site and chose Save As, your browser often saves it exactly as the server delivered it, and a growing share of sites deliver WebP. So even though the picture looked like an ordinary photo in your browser, the file that landed in your Downloads folder is a .webp. This trips people up constantly because the image displayed perfectly a moment ago, yet now won't open in their usual app.
You'll see this most often with images pulled from blogs, news sites, online stores, and stock-photo previews. Some browsers offer a Copy Image option that hands you PNG data instead of the raw WebP, which is a quick workaround if you only need a single image and don't mind re-saving it. But if you've already got the .webp file and need it in a usable format, converting it directly is cleaner and keeps the original quality.
It's worth knowing that converting away from WebP doesn't 'fix' a damaged file. The WebP is fine. You're simply repackaging the pixels into a container that more of your software understands, which is JPG for photos or PNG when you need transparency.
How to open a WebP file without converting it
The fastest way to view a WebP is the tool you already have open: a web browser. Drag the .webp file directly onto a browser tab, or press Ctrl+O (Cmd+O on Mac) and pick the file. Chrome, Firefox, Edge, and current Safari all render it instantly. This is the zero-effort option when you just need to look at the image and don't need to edit or upload it elsewhere.
On Windows 10 and 11, the built-in Photos app and Paint can open WebP files natively in recent versions, so a double-click may simply work. If it doesn't, your Windows install may be missing the WebP codec; opening the file in a browser sidesteps the problem entirely. On macOS, Preview and Quick Look support WebP on current versions of macOS, so tapping the spacebar on a selected .webp usually shows it right away. The free, cross-platform media player VLC also opens WebP if you want a desktop viewer that isn't a browser.
Viewing is only half the battle, though. The moment you need to upload the image somewhere that rejects WebP, attach it to an email, drop it into an older design tool, or send it to a print shop, you'll need to convert it. That's where having a clean JPG or PNG copy saves you.
How to convert WebP to JPG or PNG free in FileChange (in your browser)
FileChange converts WebP without uploading your file anywhere. The conversion runs entirely in your browser using the Canvas API: the page decodes the WebP, draws it onto an off-screen canvas, and re-encodes it as JPG or PNG right on your device. Your image never leaves your computer, which matters if it's a personal photo, a client asset, or anything you'd rather not hand to a server. It's free, needs no signup, and adds no watermark.
Here's the workflow. To get a universal photo file, open the WebP to JPG converter, drag your .webp onto the drop zone, and download the JPG when it finishes. JPG is the right target for photographs and anything you'll email, upload to a site that rejects WebP, or send to print. If your image has a transparent background, for example a logo or a product cutout, use the WebP to PNG converter instead so the transparency is preserved; saving to JPG would flatten transparent areas onto a solid background.
You can also go the other direction. If you're building a fast-loading website and want to shrink your existing images, the JPG to WebP and PNG to WebP converters compress your originals into WebP the same way, in-browser. There's no hard file-size cap, so large images are fine, though very large files take a moment longer to process since the work happens on your own machine. For a deeper feature-by-feature breakdown, the WebP format guide and the WebP vs JPG comparison walk through the tradeoffs.
Converting WebP with desktop and external tools
If you'd rather stay in software you already use, several desktop options handle WebP. Adobe Photoshop has read and write support for WebP built in since version 23.2 (the 2022 release); older Photoshop versions need a free plugin. The free, open-source editor GIMP opens WebP natively and can export to JPG, PNG, or back to WebP through File then Export As. Figma and Canva also import WebP, so you can place the image and re-export it in another format from there.
On Windows specifically, Microsoft Paint in recent builds can open a WebP and re-save it as JPG or PNG with File then Save As, which is a handy no-download route if you're already on a Windows machine. On a Mac, opening the WebP in Preview and then choosing File then Export lets you pick JPEG or PNG and save a converted copy. These built-in tools are perfectly adequate for a one-off conversion.
The honest tradeoff with desktop tools is friction and consistency. You're depending on your specific software version supporting WebP, you may need to install a plugin or update an app, and batch-converting a folder of files is fiddly. A browser-based converter avoids all of that, works the same on any operating system, and keeps the file local, which is why it's usually the quicker answer for someone who just needs the image converted and moves on.
Should you keep the WebP or convert it?
If the image is destined for the web, keep it as WebP, or convert your JPGs and PNGs to WebP to make your pages faster. The smaller file size directly improves load times and Core Web Vitals, and browser support is now universal among current browsers, so there's little downside online. WebP is genuinely the better format for delivering images on a website.
Convert to JPG or PNG when the image needs to live outside the browser. Email attachments, documents, print workflows, older software, and recipients who might not have up-to-date tools all favor a universal format. JPG is the safe choice for photographs; PNG is the right call when you need transparency or crisp edges on graphics, logos, and screenshots. There's no shame in keeping both: a WebP copy for the web and a JPG or PNG copy for everything else.
One thing to keep in mind about quality: converting lossy WebP to JPG re-compresses the image with a different lossy method, so there's a small, usually invisible quality change. Converting to PNG is lossless and won't degrade the image, but PNG files of photos are much larger. For graphics with transparency, PNG is the natural target; for ordinary photos you'll share widely, JPG keeps file sizes reasonable.
Frequently Asked Questions
Why won't my computer open a .webp file?
Your photo viewer or editor probably predates WebP or is missing the WebP codec. The format is newer than JPG and PNG, and many desktop apps, email clients, and older editors still don't recognize it even though every modern browser does. The quickest fix is to open the file in a web browser to view it, then convert it to JPG or PNG if you need it elsewhere.
Is WebP better than JPG?
For web use, yes. WebP files are typically 25 to 35 percent smaller than JPG at the same visual quality, and WebP also supports transparency and animation, which JPG does not. JPG still wins on universal compatibility outside the browser, so it remains the safer choice for email, print, and older software.
Does converting WebP to JPG lose quality?
There's a small quality change because JPG applies its own lossy compression on top of the image. At a high quality setting the difference is invisible for most photos. If you want zero quality loss and need to preserve transparency, convert to PNG instead, which is lossless but produces larger files for photographic content.
Do I have to upload my WebP file to convert it?
No. FileChange converts WebP entirely in your browser using the Canvas API, so the file is decoded and re-encoded on your own device and never uploaded to a server. It's free, requires no signup, and adds no watermark, which makes it suitable for personal photos and private or client images.
Can I convert a folder of WebP images at once?
Yes. You can drop multiple WebP files onto the converter and process them together, with no fixed limit on how many files you add. Because the work runs locally on your machine, a very large batch or very large individual files may take a little longer than a single small image.
How do I open a WebP file on Windows or Mac without installing anything?
On both systems, the simplest no-install method is to drag the .webp file onto a browser tab, which renders it instantly. On Windows, recent versions of the Photos app and Paint can open WebP directly; on macOS, Preview and Quick Look support it. To save a converted copy, use Paint's Save As on Windows or Preview's Export on Mac.
