How to convert PNG to JPG
- Drop a PNG into the box above, choose a file, or paste a screenshot.
- JPEG is already selected. Leave the quality at 85, or lower it for an even smaller file.
- Check the size saving in the result panel, then select Download.
PNG vs JPG at a glance
| PNG | JPG | |
|---|---|---|
| Compression | Lossless: every pixel kept | Lossy: tiny details dropped to save space |
| Photos | Very large files | Small files, looks the same |
| Text, logos, screenshots | Crisp edges | Can blur edges and add faint smudges |
| Transparency | Yes | No: filled with white |
How it works
This is where most of the size saving happens. PNG stores every pixel exactly, while MozJPEG, at the default quality of 85, throws away detail the eye barely notices, which is why a PNG photo shrinks so much. Anything transparent is composited onto white before encoding. Sharp-edged graphics are where JPG struggles: around text and thin lines it leaves faint speckles. If a screenshot looks smudged, raise the quality towards 95, or keep it as PNG.
Common uses
- Photo exported as PNG. Editors, phone apps and screen tools sometimes save photos as PNG, which makes them very large. Convert to JPG for a copy that's a small fraction of the size.
- A portal's upload limit. Job and visa portals often cap uploads at a few hundred kilobytes. Convert the PNG to JPG, and lower the quality if it still needs to be smaller.
- Emailing several photos. PNG photos add up quickly in an email. Converting them to JPG lets more of them fit under your mail provider's attachment limit.
