PNG to JPEGon iPhone and iPad.
PNG is great for screenshots and graphics, but the files are big. Fileroom shrinks them to JPEG with adjustable quality, right on your phone — often 80–90% smaller, with no compression website involved.
Free to download — no account, no uploads.
Why convert PNG to JPEG?
- JPEG files are typically many times smaller at the same visual quality.
- Upload forms with size limits accept JPEG where a PNG is too big.
- Photos and most screenshots look just as good as JPEG.
- It all happens on your device.
How to convert PNG to JPEG
- 01
Choose the image

- 03
Convert
Tap Convert. The result screen shows how much smaller the JPEG is.
Frequently asked
- Will the JPEG lose detail?
- JPEG is lossy, so some fine detail is dropped. At quality 90 or higher you won't notice. For graphics with sharp edges, like icons, PNG may still be better.
- What happens to transparency?
- JPEG doesn't support transparency, so transparent areas become white. Keep PNG if you need transparency.
