What PNG can and can't do for a JPG
A common assumption is that turning a JPG into a PNG makes it "higher quality". It doesn't. JPG compression removes some detail at the moment the file is saved, and that information is gone. The PNG will contain exactly the same pixels as the JPG, including any blockiness or color banding already there, only stored without further loss. The file also becomes larger, often two to five times, because PNG doesn't use the photo-friendly tricks that make JPG compact.
So why convert at all? Because PNG stops the damage from getting worse and opens up things JPG can't do.
Good reasons to convert
- Editing in several rounds. Every time you open a JPG, change it and save it again, it is recompressed and slightly degraded. Working from a PNG copy avoids that generational loss; you can export a final JPG at the very end.
- Adding transparency later. JPG can't store see-through pixels. If you intend to cut out a product or signature and place it on another background, start from a PNG so the editor can save the transparent result.
- Software or platform requirements. Some design tools, game engines, slide templates and printing services ask specifically for PNG.
- Graphics that were wrongly saved as JPG. A logo or screenshot saved as JPG won't get sharper, but saving it as PNG prevents new artifacts if you keep editing it.
Orientation and metadata
Phones often store photos sideways and add an orientation flag to the JPG. Modern browsers apply that flag while decoding, so the PNG comes out upright the way you see it on screen. EXIF details such as GPS location, camera model and capture date are not written into the PNG. If you want to remove that data but keep the JPG format, use Remove EXIF Data instead.
JPG, JPEG and PNG at a glance
| JPG / JPEG | PNG | |
|---|---|---|
| Compression | Lossy, tuned for photos | Lossless |
| Transparency | Not supported | Supported |
| Best for | Photos to share or upload | Editing copies, graphics, screenshots |
| Usual size | Small | Larger |
When the editing is finished and you just want to share the picture, convert it back with PNG to JPG for a compact file.
No servers involved
Everything happens in this tab. The JPGs are decoded and re-encoded by your own browser, which means private photos stay on your computer or phone and large batches don't depend on your upload speed. When the files are ready, you save them like any other download.

Frequently asked questions
Will the PNG look better than my JPG?
No, it will look identical. Converting preserves what is there but cannot restore detail that JPG compression already removed.
Why is the PNG file so large?
PNG is lossless, so it has to store all the fine noise and texture in a photo exactly. JPG discards much of that, which is why it is smaller. For sharing photos, JPG remains the more practical format.
Does the PNG get a transparent background?
No. The background of your photo stays as it is. The PNG is simply able to hold transparency if you remove the background in an editor afterwards.
Can I convert JPEG files too?
Yes. JPG and JPEG are the same format with different extensions. Both are accepted, and so are other image types if you drop them here.
How many images can I convert?
As many as your device can hold in memory. They are processed one at a time, and with more than one you can download everything as a ZIP.
