About PNG to JPG
Where PNG files come from
Screenshots, exported designs, and photos edited on a computer are often saved as PNG, which keeps every pixel and so makes very large files. Email attachments, upload forms with size limits, and older apps work better with JPG, which is far smaller for photos.
What changes
- See-through parts are filled with the colour you pick, because JPG has no transparency.
- JPG compresses with some loss. Photos look the same at High quality; sharp text and lines may get faint smudges.
- Photos shrink to a fraction of their size. Flat-colour images such as logos shrink much less, and can grow.
- Metadata inside the PNG is not copied.
Measured
Our 12-megapixel sample photo as PNG, a 12-megapixel transparent sticker, and a 1024 by 1024 pixel logo, converted at High quality in Chrome on a laptop. Phone timings are still to be measured.
| Photo, PNG to JPG | 14 MB to 1.5 MB |
|---|---|
| Logo, PNG to JPG | 47 KB to 35 KB |
| Sticker (flat colours), PNG to JPG | 60 KB to 122 KB |
| Time for the photo in Chrome (laptop) | 0.3 seconds |
In your browser
Every current browser reads PNG and writes JPG itself, so nothing extra is downloaded.
Limits
- Transparency is lost. If you need it, use PNG to WebP instead, which keeps it and is still small.
- Images with large flat areas, such as stickers and diagrams, can come out larger as JPG.
- Very large images may be reduced to about 16 megapixels on iPhones. The result says so.
Other options
- PNG to WebP: smaller than PNG and keeps transparency.
- Compress image: keep the PNG format and make it smaller, or reach a target size.
- Image to PDF on Open PDF Toolkit: put the images into one PDF.
Questions
How much smaller is a JPG than a PNG?
For photos, often around ten times smaller. Our 14 MB sample photo became a 1.5 MB JPG at High quality. For logos and screenshots with flat colours the gain is small, and the JPG can even be larger.
Are my images uploaded?
No. Your files are processed on your device. We never upload them.
What happens to the transparent background?
JPG can't store transparency, so see-through parts are filled with a colour. White is the default; you can pick black or any other colour.
Does converting PNG to JPG lose quality?
A little. JPG drops detail the eye barely notices to save space. At High or Best the difference is hard to see in photos. Sharp text and thin lines can get faint smudges around them, so keep screenshots of text as PNG.
Is JPG the same as JPEG?
Yes. JPG and JPEG are two names for the same format. The files this tool makes end in .jpg and open anywhere a .jpeg would.
Can I convert many images at once?
Yes. Choose or drop as many as you like and download them all as one zip.
