JPG to WebP
Convert a JPG to WebP for faster web pages, right in your browser with nothing uploaded.
Your image is converted inside this page. It is never uploaded.
What this tool does
To convert JPG to WebP, choose the JPEG image and download the WebP. WebP is designed to give smaller files than JPEG at similar visual quality, which helps pages load faster. The conversion happens in your browser and the result depends on the image.
Decodes your JPEG in the browser and encodes it as a WebP image.
Shows the original and new file sizes so you can see whether the conversion is worth it for that picture.
How to use it
- Choose a JPG file, or drop it into the box.
- Wait for the conversion - it takes a moment.
- Compare the original and new sizes.
- Press Download.
- Upload the WebP to your site, using the original as a fallback if you need older-browser support.
Why use this converter
Converts JPG to WebP in your browser so you can compare the file size before you commit to using it. Images are usually the heaviest part of a web page, and a smaller image file means a faster page. WebP is supported by all current browsers and is designed to be more efficient than JPEG.
Why we built it
We built the JPG to WebP converter so you can compare the new file size before you commit. Convert back with WebP to JPG and compress further with the image compressor.

Who this tool is for
- Web developers and bloggers speeding up pages
- Sellers on image-heavy sites
- SEO staff improving page weight
When to use it
- Speeding up a website or blog by shrinking images.
- Preparing images for a CMS or shop that accepts WebP.
- Checking how much a photo would shrink.
- Converting a batch of images, one by one, before upload.
How it works
The JPEG is decoded to pixels and re-encoded with the WebP encoder built into your browser. WebP uses more modern compression techniques than JPEG, which is where the savings come from.
This is a second lossy encode, so it is best done from the original source image where possible, not from a JPEG that has been saved several times already.
The saving varies by image. Detailed photographs often shrink noticeably, while already-small or very simple images may not.
Tips for the best result
WebP usually gives the same visual quality as JPG at a smaller size, which makes pages load faster.
- Compare the sizes shown and keep whichever you prefer; very small or very simple images may not shrink.
- Check the image in the browser or app you will use it in - old software may not display WebP.
- Converting from JPG does not add detail; the result is a re-encoding of the same pixels.
- Keep your JPG original as an archive.
What you give it, and what you get back
| Item | Details |
|---|---|
| Input | A JPG or JPEG image. |
| Output | A WebP image. |
| Report | Original and converted file size. |
| Where it goes | Your Downloads folder. Nothing is uploaded. |
Issues you may run into
| What you see | Why it happens | What to do |
|---|---|---|
| WebP is not smaller | The JPG was already well compressed. | Keep the original in that case. |
| Old software cannot open it | Some older programs do not support WebP. | Keep a JPG copy for those. |
| EXIF data is gone | Metadata is not carried over. | Keep the original if you need it. |
| Slight visual change | Lossy re-encoding. | Convert from the highest-quality original available. |
Assumptions and limitations
- Metadata such as EXIF is not carried over.
- Re-encoding a JPG is lossy, so work from the original if you can.
- Some older programs and print services do not accept WebP.
- One file at a time.
