None. PNG and TIFF are both lossless, so the decoded image is identical either side of the conversion.

Does transparency survive?

Yes — TIFF supports an alpha channel, unlike JPG. This is one of the few conversions where transparency is not a concern.

Which will be bigger?

Usually the TIFF, since PNG's compression is generally more effective. Both are lossless, so it is purely a storage question.

Both formats are lossless, so this conversion costs nothing in quality — it is purely about meeting a requirement. Print workflows, archives and professional imaging software expect TIFF, and PhotoTray produces it locally on as many files as you have.

Why convert

Why convert PNG to TIFF

Because something downstream requires TIFF and will not take PNG. Print production, document archives, GIS and medical imaging systems all standardised on TIFF long before PNG existed, and many have never had a reason to change. Since both are lossless, the image comes through exactly as it was.

A print or publishing workflow that specifies TIFF.
Archival systems that mandate a lossless, long-established format.
Professional imaging or GIS software that expects TIFF input.
Converting a folder of exported PNGs to meet a delivery spec.
