Smaller files, wider support
PNG is a great format for screenshots, logos and graphics, but photos saved as PNG are often very large. Many online forms, job portals and older programs also accept only JPG. This converter turns PNG images into JPG files in your browser, one at a time or in a batch.
Transparent backgrounds
PNG images can have transparent areas: a logo with no background, or a product photo cut out from its surroundings. JPG has no way to store transparency, so those areas must be filled with a solid color. You choose the color before converting. White suits most documents and websites; choose black or a brand color if the image will sit on a dark or colored background.
If you need to keep transparency, stay with PNG or use WebP, which supports it too.
Choosing the quality
JPG compression lets you trade file size for detail:
- 90 and above: almost indistinguishable from the original. A good default.
- 70 to 85: noticeably smaller files, still very good for photos.
- Below 70: small files, but blur and blocky patches start to show, especially around text.
The result list shows the original and new size of every image, so you can see how much space you saved. For a precise size limit such as 50 KB, use Compress Image with a target size instead.
When to convert PNG to JPG
- Uploading to a form that rejects PNG or has a strict size limit.
- Emailing photos that were saved as PNG by a screenshot tool or an editing app.
- Making a website faster by serving photos as JPG rather than heavy PNGs.
- Freeing up storage on your phone or computer.
Keep PNG for logos, icons, diagrams and screenshots of text, where its sharp edges matter more than file size. To go the other way, use JPG to PNG.
Why PNG photos are so large
PNG saves every pixel exactly, with no loss. That is perfect for flat colors and text, where it compresses well, but a photograph contains millions of slightly different colors, which PNG cannot squeeze much. JPG instead keeps the parts of the picture your eye notices and simplifies fine detail, which is why the same photo is often many times smaller as a JPG. Screenshot apps and some editors save everything as PNG, so photos end up far larger than they need to be.

Private by design
Your PNG files are converted inside your browser. They never leave your device and are not stored anywhere. Converting also drops hidden metadata, such as the software that created the image or the location where a photo was taken.
Works on phones and computers
The converter works in any up-to-date browser on iPhone, Android, Windows and Mac, with no app to install and no sign-up. You can add many files at once and download them together as a ZIP. On a computer, drag files onto the drop area or paste a copied image with Ctrl+V or Cmd+V. Large images take longer on older phones because the work is done on the device itself, and a progress bar shows each file as it is converted.
Whichever way you convert, the result list shows the size of every file, so you can confirm it meets any upload limit before you submit it.
Tips
- Keep the original PNG until you have checked the JPG looks right.
- Screenshots of text stay clearer at quality 90 or above.
- Batch conversion keeps file names, so photo-1.png becomes photo-1.jpg.
