How it works
- 01
Add your JPG files
Drop, paste or pick any number. The files stay in this tab, and the page sends them nowhere.
- 02
Check the new sizes
PNG keeps every pixel, so most files grow. Each row shows the new size.
- 03
Download
Save one file, or the whole batch as a zip. Your JPG files stay as they are.
Expect a bigger file
Know this before you start. A JPG got small by throwing detail away, and a PNG throws nothing away. So the PNG stores exactly what the JPG kept, including the blocky marks its compression left behind. Photos often come out three to five times bigger.
That is not a fault in either format. They are built for different jobs. JPG is for photographs you want small. PNG is for pictures that must stay exact: screenshots, line art, anything with text, and anything with a see-through part. Converting a photo to PNG gives you a bigger file with the same picture in it. Nothing can put back what the JPG already dropped.
So convert when you need the format. Something you use may only read PNG. You may be about to edit and want no more loss on each save. You may need to cut a see-through area, which a JPG cannot hold. Those are good reasons. Converting will not make the photo look better, and no tool can.
- Size
- Usually larger. PNG keeps every pixel, so nothing is cut.
- Quality
- No setting. PNG has no lossy mode, so there is no dial.
- Batch
- No limit on files. One at a time, so memory stays flat.
- Originals
- Never touched. Converting always writes a new file.
