How to convert PNG to JPG
- Choose your PNG images, or drop them on the box.
- Pick the quality you want. Medium is a good balance of size and sharpness.
- Tap Convert to JPG, then save each file or all of them as a ZIP.
About this tool
PNG keeps every detail and supports transparent backgrounds, which makes the files large. Screenshots and photos saved as PNG are often several times bigger than the same picture saved as JPG. Many websites, forms and email limits ask for JPG, so converting is the quickest fix.
JPG does not support transparency, so any see-through area in your PNG is filled with white. If you need to keep a transparent logo, keep the PNG and use the JPG only where a white background is fine.
The conversion happens inside your browser, so your pictures are never uploaded to any server.
Tips and common problems
- Screenshots and photos shrink the most. A PNG screenshot can drop to a fraction of its size as a JPG.
- Logos and text with sharp edges can look slightly softer as JPG. Choose High quality for those, or keep the PNG.
- Transparent background? It will turn white. If you need transparency, do not convert.
- A form still says the file is too big? Choose Low, or make it smaller with the Image Resizer.
- Converting many files on a phone? Do 10 to 20 at a time so the browser does not run out of memory.
Common questions
Why convert PNG to JPG?
JPG files are much smaller for photos and screenshots, and almost every website, app and form accepts them.
Will I lose quality?
JPG is a lossy format, so a small amount of detail is lost. At High quality the difference is hard to see for photos.
What happens to a transparent background?
JPG cannot be transparent, so transparent areas become white.
Can I convert many PNG files at once?
Yes. Add as many as you like, tap Convert to JPG, then save them one by one or all together as a ZIP.
Are my images uploaded?
No. Everything runs on your own device and your images are not sent to us.
PNG to JPG in detail
PNG versus JPG
PNG stores every pixel exactly, which is perfect for logos, screenshots, diagrams and images with sharp text, but it makes photographs very large. JPG uses lossy compression designed for photos and usually produces files that are a fraction of the size. That difference is the main reason to convert a heavy PNG to JPG.
When converting makes sense
Convert when a form or website rejects PNG, when a photo saved as PNG is too big to email, when you want to save phone storage, or when a printing service only takes JPG. Screenshots of a game or a photo from a camera are good candidates because they contain smooth colours where JPG compression works well.
When to keep the PNG
If the image has a transparent background, a very small logo, thin lines or crisp text, JPG may blur the edges slightly and will replace transparency with a solid colour. In those cases keep the PNG, or at least keep a copy before converting.
Choosing quality
High is almost indistinguishable from the original for photos and still saves a lot of space. Medium is the sensible default for sharing. Low produces the smallest files and is fine for previews, but you may notice blocky areas around edges. You can convert many images together and save them as one ZIP.
Privacy
All conversion is done inside your browser. Nothing is uploaded, so you can safely convert private screenshots and documents.
