PNG is the right landing place for a bitmap that has to stay exact: line art, a screen capture saved by legacy software, a scanned form heading into OCR. It compresses losslessly, so the file usually drops by half or more without a single pixel being altered. The rewrite happens in this tab and the bitmap never travels.
Frequently asked questions
- Does PNG change any of my pixels?
- Not one of them. PNG compression is lossless, so the image that comes out is bit for bit the image that went in, merely stored more sensibly.
- How much space does PNG save over BMP?
- It depends entirely on the content: line art and flat graphics can shrink by ninety percent, while a noisy photograph saved as a bitmap may only halve.
- Should a scanned document be PNG or JPG?
- PNG when the scan will be read by software, archived, or carries fine print. JPG when it simply has to be small enough to email.
