How do I convert JPG to PNG?
- Choose or drop your JPG.
- Select PNG as the output — there is no quality slider, because PNG never discards detail.
- Press Convert, then download your PNG copy.
When should you convert JPG to PNG?
Every time a JPG is edited and saved again, its lossy compression throws away a little more detail, and the blocky artefacts add up. A PNG copy stops that from happening: from this point on, the image is stored exactly, no matter how many times you open, change and save it.
- You plan to annotate or retouch an image over several sessions and do not want it degrading on every save.
- A sticker maker, icon tool or design upload only accepts PNG files.
- You want a lossless starting point before cutting out the background in an image editor.
What do you keep and what do you lose?
You keep
- Every pixel exactly as the JPG decodes it, including any compression artefacts already there.
- The original width and height.
You lose
- The small file size — expect a much bigger file, because lossless storage takes more space.
- Embedded metadata such as camera model and GPS position.
In our test (Chromium 156.0.8078.4, 2026-10-23), converting a landscape photo (a quality-92 JPG copy of the original PNG) from JPG to PNG changed its size: 750 KB → 4.8 MB (6.4× larger).
Do you still have the original?
Before converting a JPG to PNG, check whether the image started life as a PNG: a screenshot, a chart or an export from a design tool that someone later saved as JPG. If it did, go back to that original instead. Turning the JPG back into a PNG does not undo the JPG step; the artefacts it added become part of the picture, and PNG has to store them exactly.
Our website screenshot shows the cost. The original PNG was 78 KB. We made a quality-92 JPG copy of the original PNG and converted it back to PNG, and the result came to 227 KB, because the faint noise JPG leaves around text and edges is exactly the detail lossless compression cannot squeeze. The photo and the logo also ended up larger than their original PNGs, if less dramatically. So use this converter when the JPG is all you have, which is common with images copied from email or chat apps; when the original exists, it is both smaller and sharper.
JPG to PNG questions
Why is the PNG so much bigger than the JPG?
JPG saves space by approximating detail; PNG records every pixel exactly. Storing a photo losslessly therefore costs far more bytes: our test photo, a quality-92 JPG copy of the original PNG, changed size: 750 KB → 4.8 MB (6.4× larger). That is normal, and why PNG suits images you are still editing.
Will the PNG have a transparent background?
No. A JPG has no transparency to carry over, so the PNG keeps the same solid background. PNG can store transparency, but you need to remove the background in an image editor first; converting alone never makes areas see-through.
Can I keep re-saving the PNG without losing quality?
Yes. Because PNG is lossless, opening and saving the file again changes nothing, however many times you do it. A JPG, by contrast, loses a little detail on every save, which is the main reason to switch formats while you edit.
