About JPG to PNG
Where JPG files come from
Cameras, phones, and most websites give you JPG. Each time a JPG is edited and saved, it loses a little more detail, and some design tools, game engines, and upload forms only take PNG. Converting once to PNG gives a copy that never degrades further.
What changes
- The PNG is a lossless copy of the decoded JPG. Further edits and saves lose nothing.
- The picture is turned upright for good, so apps that ignore orientation still show it correctly.
- The date, camera, and location stored in the JPG are not carried over.
- The file is several times larger.
Measured
Our 12-megapixel sample photo as JPG and a 1024 by 1024 pixel logo as JPG, converted in Chrome on a laptop. Phone timings are still to be measured.
| Photo, JPG to PNG | 2.1 MB to 13 MB |
|---|---|
| Logo, JPG to PNG | 48 KB to 179 KB |
| Time for the photo in Chrome (laptop) | 0.4 seconds |
In your browser
Every current browser reads JPG and writes PNG itself, so nothing extra is downloaded.
Limits
- The PNG can't recover detail the JPG already lost.
- PNGs of photos are large, about six times the JPG for our sample.
- Very large images may be reduced to about 16 megapixels on iPhones. The result says so.
Other options
- JPG to WebP: a smaller file for websites.
- Compress image: make the PNG smaller by reducing its colours.
- Image to PDF on Open PDF Toolkit: put the images into one PDF.
Questions
Does JPG to PNG improve quality?
No. The PNG is an exact copy of what the JPG shows, including any blockiness the JPG already has. What PNG adds is that editing and saving again loses nothing more.
Are my images uploaded?
No. Your files are processed on your device. We never upload them.
Will the PNG have a transparent background?
No. JPG has no transparency, so the background stays as it is, usually white. Removing a background is a different job.
Why is the PNG so much bigger?
PNG stores every pixel without loss, and JPG throws away detail to stay small. Our 2.1 MB sample photo became a 13 MB PNG.
Will my photo stay the right way up?
Yes. Phone photos record how the phone was held. The converter turns the picture upright, so the PNG looks right in every app.
Can I convert many images at once?
Yes. Choose or drop as many as you like and download them all as one zip.
