Convert WebP to JPG online: why you can't open those images and how to fix it

Learn what the WebP format is, why your computer can't open it, and how to convert it to JPG in seconds without uploading your images to any server.

It has happened to you: you save an image from a website, try to open it in Word, PowerPoint, or your computer's photo viewer, and it does not work. The file ends in .webp and your program has no idea what to do with it. It is not a broken file or a virus: it is a relatively new image format that the web loves but many desktop programs still do not understand. The fix is to convert it to JPG, and you can do it in seconds without installing anything or uploading your images anywhere.

What is WebP and why does it exist

WebP is an image format created by Google in 2010 with a very specific goal: to make web pages load faster. It produces files that are 25 to 35 percent smaller than a JPG of the same visual quality, which is a huge difference when a page has dozens of images. For Google, which wants the web to be fast (and wants users not to leave a page because it takes too long to load), it is the ideal format.

And it has worked: today, most large websites serve their images in WebP. When you browse an online store or a news site, many of the photos you see are WebP, even though you do not notice because the browser displays them without any issue.

The problem: saving an image from the web in 2026

The trouble starts when you right-click an image and select "Save image as." On many sites, what downloads is a .webp file, not the .jpg or .png you expected. And when you try to use that image outside the browser, you run into this:

  • Microsoft Word and PowerPoint (versions before Office 2021) do not recognize the format and will not insert the image.
  • Older editing programs (Paint on Windows 10, third-party photo viewers) cannot open it.
  • Some online submission forms, government portals, and institutional websites only accept JPG or PNG.
  • Certain online printing services reject WebP files.
  • If you send the image by email to someone with an older system, they may not be able to view it.

The browser can read WebP perfectly, but once the file leaves the browser, compatibility depends on the program opening it. And that is where things still break down.

The privacy problem nobody mentions

Most online converters work by uploading your image to a server, converting it there, and sending back the result. For a product photo or a landscape, you might not care. But think about the times you save an image that contains sensitive information: a screenshot with personal data, a picture of a document, a photo with medical or financial information.

Those images end up on third-party servers, processed by companies whose data practices you know nothing about and whose retention policies you have never read. It is an unnecessary risk, because converting from WebP to JPG is an operation your own browser can handle without sending anything anywhere.

How to convert WebP to JPG without uploading anything

With the WebP to JPG conversion tool from SocialShrink, the process is instant:

  1. Open the tool in your browser. You do not need to create an account or install anything.
  2. Drag the .webp file in (or select it from your device). The image loads into your browser's memory and is not uploaded to any server.
  3. The conversion runs automatically using the browser's Canvas API. Your file is re-encoded from WebP to JPG on your own device.
  4. Download the resulting JPG. Ready to insert in Word, send by email, upload to any platform, or print.

Does converting from WebP to JPG lose quality?

Let me be honest here. Both WebP and JPG are lossy compression formats. The original WebP already discarded some visual information when it was compressed, and converting to JPG applies a second round of compression. However, if the conversion is done at high quality (90-95%), the additional loss is practically invisible to the human eye.

For photos you plan to use in documents, presentations, emails, or social media, the difference between the original WebP and the converted JPG is imperceptible. Only in a technical pixel-by-pixel analysis would you detect any difference, but in real-world use nobody is going to notice.

When it makes sense to keep the WebP

You do not always need to convert. If the image is going to be used on a website (for example, on your blog or online store), WebP is the better choice over JPG: it weighs less and all modern browsers support it. Same goes if you are sending the image to someone who uses up-to-date software (Office 2021 or later, macOS, any recent Linux distribution) -- the WebP will open without issues.

Convert to JPG when you need guaranteed compatibility: documents that will be opened in older programs, forms that only accept JPG, files for printing, or when you do not know what software the recipient uses.

If you need the opposite (convert JPG to WebP so it weighs less on your website), there is a reverse WebP conversion tool. To convert PNG to JPG or reduce the size of any image without changing formats, the conversion and compression tools cover those cases. And the multiformat tool lets you adapt a single image to the dimensions of every social media platform at once.

Frequently asked questions

Why do websites save images in WebP instead of JPG?

Because WebP weighs 25 to 35 percent less than JPG at the same visual quality. For a website with hundreds of images, that translates into pages that load noticeably faster, less data consumption for the user, and better Google rankings (since Google penalizes slow pages). It is a logical decision for the web, even if it causes friction outside of it.

Can I convert multiple WebP files at once?

Yes, the tool lets you process files one by one quickly. If you have many files to convert, you can drag them in consecutively. Each conversion takes less than a second because everything happens locally, with no server to wait on.

Will the resulting JPG file be larger than the original WebP?

Generally yes, slightly. WebP is more efficient than JPG at compression, so the same visual content usually weighs a bit more in JPG. The typical difference is between 20 and 35 percent more in file size. For a photo in normal use this barely matters (we are talking about going from, say, 150 KB to 200 KB), but if file size is critical, you can use the compression tool after converting to bring it down to whatever size you need.

Is there a way to make Windows open WebP directly?

Windows 10 (with recent updates) and Windows 11 already support WebP natively in the photo viewer. The problem usually lies with third-party programs or older versions of Office. If you update all your software, the issue will likely disappear. But if you work with programs you cannot update, or you need to send the image to someone whose system you do not control, converting to JPG remains the most reliable solution.
