Why convert TIFF to PNG instead of JPG?

PNG is lossless — scans, diagrams, and documents keep every pixel exactly, where JPG would soften text and line art. Choose PNG when fidelity matters and JPG when the content is photographic and file size matters more.

Is any quality lost going from TIFF to PNG?

No — both formats are lossless for standard images, so the PNG is a pixel-exact copy in a far more web-friendly wrapper. Very high bit-depth TIFFs (16-bit channels) are reduced to standard 8-bit, which only matters for professional color grading.

Can browsers display TIFF files directly?

Mostly no — TIFF was never adopted as a web format, and most browsers won't render it inline. Converting to PNG is the standard way to publish scanned material on the web without quality loss.
