Photos for a website
Smaller images load faster. A photo as JPG is much lighter than the same photo as PNG.
Convert PNG to JPG in bulk, free
Add up to 10 PNG images and get smaller JPG files back. You pick the quality, and everything is converted inside your browser with nothing uploaded.
Any see-through areas are filled with white, or the colour you pick, because JPG cannot be transparent. Each file can be up to 25 MB.
What you get
- Smaller files
- A photo saved as JPG is usually a fraction of the size of the same photo as PNG.
- You choose the quality
- A slider from 50% to 100%, starting at 95%. Lower is smaller, higher looks better.
- Ten files at once
- Convert a batch in one go and download a ZIP. Each file can be up to 25 MB.
- Nothing uploaded
- The browser converts the images on your own device, so they never reach a server.
- You pick the fill
- See-through areas are filled with white by default, so they do not turn black. Choose black or any other colour if you prefer.
- Free
- No sign-up, no watermark, and no limit on how many batches you convert.
Convert in four steps
Add your PNGs
Choose files or drag them onto the page.
Set the quality
Leave it at 95% for a result that looks the same, or lower it to save more space.
Convert
Each file shows its new JPG name and size, so you can see how much was saved.
Download
Save one JPG, or take the whole batch as a ZIP.
When JPG is the better format
Email and messaging
Get under an attachment size limit without shrinking the picture itself.
Forms that ask for JPG
Many application and upload forms accept only JPG. Convert once and upload.
Removing a see-through background
Converting fills transparent areas with white, or any colour you pick, which is a quick way to get a solid background.
What the quality setting does
| Setting | What to expect |
|---|---|
| 100% | The best JPG can look, and a big file. Rarely worth it over 95%. |
| 95% (default) | Looks the same as the PNG for most photos, with a much smaller file. |
| 80 to 90% | Good for the web. Differences show only when you zoom in. |
| 50 to 75% | Small files, with visible blockiness on detailed areas. |
Sizes depend on the picture, so check the size shown next to each converted file. To go back to a lossless format, use the JPG to PNG converter.
How the conversion works
Your browser opens the PNG, paints a solid background (white unless you chose another colour), draws the image on top, and saves the result as a JPG at the quality you chose. All of this happens on your own computer, and the file is never sent anywhere.
