Produce a genuine TIFF file that print shops, publishers and document systems will actually accept.

Print bureaus, journal submission systems, patent offices and document-management platforms still specify TIFF, usually because it is a stable, lossless, decades-old container with no surprises. Converting to it should be trivial, and yet a lot of free converters quietly hand back a PNG with the extension changed — which opens fine in a browser preview and is then rejected by the system you needed it for. This one writes a real baseline TIFF: proper little-endian header, correctly ordered tag directory, 8 bits per channel, single uncompressed strip. Transparency is preserved when the PNG has any, written as RGBA with the ExtraSamples tag set so other software interprets the alpha channel correctly; fully opaque images are written as plain RGB. Since the output is uncompressed, expect it to be substantially larger than the PNG — that is normal and what these workflows expect.
A real one. It writes a proper TIFF header and tag directory with uncompressed 8-bit pixel data, which is why print and archival systems accept it.
Yes. Images with an alpha channel are written as RGBA with the ExtraSamples tag set; fully opaque images are written as RGB.
The output is uncompressed, so it stores every pixel at full size. Archival and print workflows expect this; compress it later if your recipient allows it.
None. Both formats are lossless, so the TIFF holds exactly the pixels the PNG did.
