How to use it
- Add your PNG files.
- Choose the background colour for any transparent areas.
- Set the JPG quality.
- Convert and download.
What it keeps
- Pixel dimensions.
- Appearance of opaque areas, within JPG's lossy limits.
What it removes or changes
- Transparency becomes your chosen colour.
- JPG is lossy. Sharp edges, text and flat colours can show fringes or noise.
- The file is usually much smaller for photos. For simple graphics, it may not be.
- Metadata follows your option.
Limits
- Screenshots with small text and line art are better kept as PNG.
- You cannot go back to transparency after converting.
- A JPG saved at low quality cannot be repaired by raising it later.
Compatibility
JPG is accepted nearly everywhere, including upload portals that cap size or reject PNG. It is the usual way to make a screenshot-heavy photo or a large PNG photo smaller and easier to send.
Privacy
Conversion runs in your browser tab. The PNG is not uploaded, and nothing is kept after you close the page.
PNG vs JPG for this job
PNG keeps every pixel and transparency but is big for photographs. JPG throws away fine detail for a much smaller file. Photos and complex scenes belong in JPG. Graphics with text, sharp lines, flat colour or transparency belong in PNG.
Troubleshooting
Black or white background appeared.
That is the flattening colour. Change it to suit where the image goes.
Text looks fuzzy.
Increase quality, or keep the PNG for text-heavy images.
The JPG is larger than the PNG.
Flat graphics compress well as PNG. Keep the PNG.
