How do I convert a WebP to a JPG?
Add your WebP files, choose a quality (90 works well) and download the JPG versions. JPG is the format nearly every program, printer service, form and email system accepts. If the WebP has transparent areas they are filled with white or black, because JPG cannot store transparency.
Why convert WebP to JPG
WebP is a newer format designed for the web, and browsers handle it well, but older software, some upload forms and some print services still ask for JPG. Saving a picture from a web page often gives a WebP you cannot use elsewhere, and converting it is the quickest fix.
JPG is lossy, so each conversion re-compresses the picture. Use a high quality setting, keep the WebP original, and convert once from it rather than converting a JPG again.
It runs in your browser. Your pictures are never uploaded, and there is no account to make.
How the conversion works in detail
Your browser does the work. When you add a WebP file, the page reads it with the browser's File API (the file is not uploaded), asks the browser to decode it into raw pixels, and draws those pixels on a canvas of the same size. The canvas is then saved as JPG (JPEG) with the browser's own encoder, and the result is offered as a download. A WebP file is a format developed by Google that can be lossy or lossless and supports transparency and animation; a JPG file is the most common photo format: it stores each picture as a compressed, lossy approximation of the original, with no transparency. Because JPG has no transparency, any see-through area is first filled with the background colour you choose (white by default), and the quality slider sets how much detail is traded for a smaller file. Everything is processed one picture at a time, in your browser's memory, which is why several pictures at once work well but pictures over about 100 megapixels are refused.
How to convert, step by step
- Add your WebP files: drop them on the box, press the box to choose them, or paste a picture.
- Choose the background colour and quality (JPG is lossy: 90 is a good balance, 100 is the largest and 70 is noticeably smaller).
- Wait a moment: each picture shows its new size and how much smaller or larger the file became.
- Press Download next to one picture, or Download all to save every converted file in turn.
- Open a converted file to check it before you delete the original WebP file.
What changes in the conversion
What stays the same and what does not when WebP becomes JPG.
| Aspect | What happens |
|---|---|
| Pixels and size in pixels | Kept exactly: the width and height do not change |
| File size | Often larger: WebP compresses better than JPG |
| Quality | A small loss: JPG is lossy, so each conversion discards a little detail. Keep the original |
| Transparency | Lost: JPG has no transparency, so see-through areas are filled with your background colour |
| Animation | Lost: only the first frame is kept, because the canvas holds one picture |
| Camera details, date and GPS location | Removed. A canvas holds only pixels, so the new file carries none of the original's metadata, which also helps privacy |
| Orientation | Applied: a photo that was rotated by a camera setting is turned upright in the new file |
| Colours | Converted to the standard sRGB range. Pictures with a wider colour range (some AVIF, HEIC and WebP files) may look a touch less saturated |
When to use it
- A picture you saved from a web page arrives as WebP and will not open in your program
- A form, email system or print service asks for JPG
- Sharing a picture with someone using older software
- Making a copy that every device can show
Problems you may run into
Most problems come from the formats involved, not from the tool.
| What you see | Likely cause | What to do |
|---|---|---|
| A WebP file will not open or shows an error | The file is damaged, is not really WebP (it was only renamed), or your browser cannot decode it (use a current browser; very old ones lack WebP) | Open the file in another program to check it, or try Chrome, Edge or Firefox |
| The background turned white (or the colour I chose) | JPG cannot store transparency | Choose another background colour, or convert to PNG or WebP to keep it see-through |
| The result looks softer or has fuzzy edges | JPG is lossy, and text or sharp lines show compression most | Raise the quality to 95 to 100, or use PNG for screenshots and text |
| My animation is now a still picture | A converted picture is a single frame | Use the GIF maker or video to GIF tool to make animations |
| Colours look a little different | The picture was converted to the standard sRGB range | Compare at full size; for colour-critical work convert in a colour-managed editor |
| The camera date or GPS location is gone | Metadata is not copied, by design | Keep the original if you need it, or write the details in the file name |
| 'Too large to process' | The picture is above about 100 megapixels | Reduce it first with the image resizer |
| Several downloads are blocked | The browser asks before saving many files at once | Allow multiple downloads for this site, or download the pictures one by one |
Mistakes it helps you avoid
- Converting an animated WebP: only the first frame is kept.
- Expecting transparency to survive: JPG fills it with a solid background.
- Converting a JPG to WebP and back: you lose quality each time, so convert from the original.
- Setting a low quality and then seeing blocky edges.
How the conversion works
Four steps, all inside your browser.
1. The file you choose is read by your browser. It is not sent to a server.2. The picture is decoded to pixels and drawn on a canvas the same size as the original.3. The browser's encoder saves the canvas in the new format, at the quality you set for JPG and WebP.4. The new file is offered as a download. Metadata such as camera details and location is not carried over.
Browsers decode the picture to pixels and re-encode a canvas with the format and quality you choose (MDN: HTMLCanvasElement.toBlob). Because the picture is redrawn, camera details and location data are not copied to the new file, and an animated picture keeps only its first frame. Very large pictures (over about 100 megapixels) are refused, since many phones cannot hold them in memory.
Example: banner.webp to banner.jpg
You have banner.webp and need a JPG file.
- You choosebanner.webp
- You getbanner.jpg
- SettingQuality 90
The JPG is a still picture that opens in almost any program.
Sizes depend on the picture, so this tool shows the before and after size for each file instead of promising a percentage.
Terms on this page
- Lossy
- A format that discards some detail to make the file smaller, such as JPG.
- Lossless
- A format that stores the pixels without losing detail, such as PNG.
Common questions
Why is a downloaded picture a WebP?
Many websites serve WebP because it makes pictures smaller than JPG at similar quality, so saving the picture saves the WebP file.
Does it work with animated WebP?
Only the first frame is converted. The result is a still JPG.
Will quality be lost?
A little, because JPG is lossy. A quality of 90 or higher keeps most detail.
Is anything uploaded?
No. Your browser does the conversion on your own device.
Can I convert several files at once?
Yes. Drop in many WebP pictures and download each result or use Download all.
Where these numbers come from

- MDN Web Docs — Using files from web applications How a page reads a file you choose without uploading it.
- MDN Web Docs — Image file type and format guide Which formats are lossy or lossless, which support transparency, and where they are best used.
- Google for Developers — WebP WebP lossless images are 26% smaller than PNGs and lossy WebP images 25-34% smaller than comparable JPEGs.
