WebP to JPG Converter

You save a photo from a website, or a sticker from a chat, and the file ends in .webp. It opens in the browser, but the job portal says "JPG, JPEG or PNG only", the old photo editor will not open it, or the print shop's machine does not know it. Converting WebP to JPG solves that. Here is why WebP shows up, what the conversion costs, and how to do it.

How to convert WebP to JPG

1. Choose the WebP files at the top of the page. One or up to 50 at once.
2. Keep the quality at 92% for a JPG that looks like the original. Lower it only if you need smaller files.
3. Download each JPG, or all of them as one ZIP.

The pixel size is kept exactly: a 1,200 × 800 WebP becomes a 1,200 × 800 JPG.

Why so many images are WebP now

WebP is an image format Google released in 2010 to make web pages lighter. Google's own comparison found lossy WebP files 25 to 34% smaller than JPGs of the same visual quality, and lossless WebP about 26% smaller than PNG. Every current browser displays it, so large sites, shopping sites, news sites and image search results serve WebP to save bandwidth.

When you right-click and save, the browser saves the file in the format it received. So the "photo" from a website is a WebP, even when the page looked like it was showing a JPG.

The trouble is everything outside the browser. Many government and exam portals list only JPG and PNG. Older versions of Photoshop, MS Paint, office software and photo kiosks may not open WebP at all. That is when the conversion is needed.

What converting does to the size

The JPG is usually larger than the WebP it came from, because WebP is the more efficient format. We encoded our test images as WebP at 80% quality, then converted them here at the default 92%:

That growth is not lost quality; it is JPG being less efficient. The picture is the one the WebP decoded to, saved in a format that needs more bytes for it. If the size matters, lower the quality slider; around 80% the JPG of a photo is usually close to the WebP's size again. For a form's KB limit, use the Image Resizer in KB after converting, which finds the size for you.

Each conversion took between half a second and 1.3 seconds on a desktop browser.

Does WebP to JPG lose quality?

A little. A lossy WebP has already thrown some detail away; encoding it again as JPG approximates that approximation. At 92% quality the second loss is too small to see at normal size. At 70% and below, faint blocks appear around sharp edges, most visibly around text in screenshots.

Convert once. If you need to edit the picture, convert to JPG, edit, and save once at the end. Or keep an untouched copy of the WebP, edit a lossless PNG of it, and make the JPG last; the JPG to PNG Converter explains why PNG loses nothing on each save.

Transparent WebP and stickers

WebP can store transparency, which is why WhatsApp stickers and many logos are WebP. JPG cannot. The converter fills every transparent pixel with the background colour you choose, white by default, and blends semi-transparent edges so they stay smooth. A note appears beside any file where this happened.

For a sticker, choose a colour that suits where the JPG will be used, or keep the WebP if you need the transparency. For transparency in a format older software understands, use PNG instead.

Animated WebP stickers convert to a still JPG of the first frame, because a JPG holds one picture.

Opening WebP without converting

You may not need to convert at all to look at the picture:

• Any current browser opens WebP: Chrome, Edge, Firefox and Safari. Drag the file into a browser tab.
• Windows 10 and 11 open WebP in the Photos app.
• Most Android galleries open WebP, since Android has read the format for years.

Converting matters when the file has to go into something that refuses it: a form, a print kiosk, an old program.

When a converted JPG is still rejected

Too many KB. Converting keeps the pixel size, so a large WebP gives a large JPG. Set the limit with a KB tool.

A dark sticker background. If the WebP was transparent and you picked black, the JPG background is black. Convert again with white.

The extension was only renamed. Changing .webp to .jpg in a file manager does not change what is inside, and many portals check the contents. A file from this page is a real JPG.

Converting a batch of saved images

Choose up to 50 WebP files at once: in the file dialog, hold Ctrl (Cmd on a Mac) to pick several, or press Ctrl + A to take every file in the folder. They are converted one after another, so even a phone with little memory gets through a large batch. Each file shows its own result as soon as it is ready, with its size before and after, and a Download button.

With two or more converted, Download all as ZIP saves every JPG in one file. Names are kept, with .webp replaced by .jpg; two files with the same name become "name.jpg" and "name (2).jpg" rather than one overwriting the other.

Moving the quality slider or changing the background colour converts every file again with the new setting. Adding files later converts only the new ones, so a long batch is not redone.

WebP to JPG on a phone

On a phone, a picture saved from Chrome or from a shopping app often lands in Downloads as a WebP, and a form then refuses it. Open this page in the same phone's browser, tap the file button, and choose the picture from Downloads or the gallery; Android lets you choose several. The JPG downloads back to the phone, ready for the form. Nothing is installed and nothing is uploaded.

WebP, JPG and PNG side by side

What this tool assumes

• Each WebP is decoded by your browser and saved as a JPG at the quality chosen, 92% by default, at exactly the same pixel size.
• Transparent and semi-transparent pixels are blended over the background colour, white by default. An animated WebP gives its first frame.
• Other image types are accepted too; whatever goes in is saved as JPG.
• Images up to 50 megapixels are converted, up to 50 files at a time, one after another, with a ZIP for several.
• The files stay on your device. The JPGs carry none of the location or camera details of the originals.
