WebP to JPG Converter
Chrome and other modern browsers save images as WebP because they are smaller. Most people do not notice until they try to open one in Outlook, Word, or PowerPoint and it will not load. Drop your file in here and get a JPG (or PNG) back, with nothing uploaded anywhere.
Explain like I'm 5 (what even is this calculator?)
You drop a WebP picture in. The tool reads it in your browser, paints it onto an invisible canvas, and saves a fresh copy as JPG or PNG. Your old software (Word, Outlook, that ancient photo viewer your dad still uses) can open the new file. The original is untouched, and the file is never sent anywhere.
Convert
Converted files
WebP files are decoded by the browser's native image pipeline, drawn to an HTMLCanvasElement, then re-encoded with canvas.toBlob at the chosen format and quality. JPEG quality is a fraction (slider value ÷ 100); PNG is lossless. JPEG cannot store transparency, so a white background is painted before the image is drawn. Resize uses contain-fit, preserving aspect ratio. Size delta = (1 − new size ÷ original size) × 100, expressed as a percentage.

What is WebP, and why does it keep showing up on your computer?
WebP is Google's image format. It came out in 2010, has been native to Chrome and Edge for years, and finally landed in Safari and Firefox too. Websites use it because the same photo, encoded as WebP, is roughly a third smaller than a JPEG. Smaller files mean faster pages, which means happier users and slightly better Google rankings. Hard to argue with.
The catch is that desktop software has not always kept up. Older Outlook installations, older Word, older PowerPoint, the photo viewer baked into a 2017 laptop, the company image library that still uses ImageMagick from 2014: they will all stare blankly at a WebP file and refuse to open it.
The "Save image as JPG" trick that does not always work
If you right-click an image in Chrome and pick Save image as, the file dialog sometimes offers a JPG option in a dropdown. Sometimes it does not. It depends on the image, the version of Chrome, and the phase of the moon. When the option is missing, this tool is the fix: save the WebP, drop it in, get a JPG out.
Bulk conversion
The dropzone accepts more than one file at a time. Pick a folder of WebPs, drag the lot in, and the tool processes them in order with a download button per file. There is no upload step, so the only ceiling is your device's memory.
Privacy: nothing leaves your browser
Every other "free WebP to JPG" website works by uploading your file, converting it on a server, and sending it back. Even when that is honest, it is an extra hop through the public internet for an image you might be reluctant to share. This tool does the work in your own browser tab, using the Canvas API. Open your developer tools and watch the Network panel: there are no requests when you press Convert.
What this tool does not do
If your WebP is animated (rare, but it happens), the tool takes the first frame and warns you. JPG cannot represent animation, and PNG can only with a lot of fiddling that is out of scope here. Re-encoding to JPG is also lossy by definition: you are throwing some quality away for a smaller, more compatible file. Going from a heavily compressed WebP to a JPG will not magically make it look sharper.

Frequently asked questions
Why does Chrome save images as WebP?
Chrome saves images in whatever format the website served them in. A growing share of sites now serve WebP because it is roughly 25 to 35 percent smaller than the equivalent JPEG, which makes pages load faster. Chrome is just keeping the format the page used. Edge, Firefox and Safari behave the same way.
How do I convert WebP to JPG?
Drop the WebP file onto this page, choose JPG as the output format, and click Convert. The converted file appears with a download button. Nothing is uploaded; the conversion happens in your own browser tab.
Can I open WebP in Word, Outlook, or PowerPoint?
Recent versions of Microsoft 365 (2021 onwards) do support WebP, but many people are still on older builds where WebP simply will not insert. Older Outlook clients are the worst offender. Converting to JPG or PNG fixes it everywhere.
Does this upload my files anywhere?
No. Decoding and re-encoding both happen in your browser, on your device, using the standard Canvas API. You can pull the network cable mid-conversion and the tool will still finish the job.
What is WebP and why is it used?
WebP is a Google-designed image format that compresses photographs and graphics more efficiently than JPEG or PNG. Smaller files mean faster page loads, which is why so many websites have switched to it. Every modern browser can display WebP, but a lot of desktop software still cannot.
How do I stop Chrome saving images as WebP?
Honestly, you cannot, not directly. Chrome saves what the website sends. Some Chrome extensions claim to force JPEG by stripping the Accept header that requests WebP, but they break a lot of sites. The pragmatic fix is to save the file as WebP and run it through a converter like this one when you actually need a JPG.
Will the JPG be the same quality as the WebP?
Close, not identical. JPG is a lossy format, so there is always a small quality cost when re-encoding. The default quality of 92 is high enough that the difference is invisible to almost everyone. Drop the slider lower if you want smaller files at the cost of a bit of fuzz.
