For years I saved bitmaps I was working on, in TIFF because it was a lossless-storage format. I avoided PNG at that time because I was under the mistaken idea it had lossy compression, as JPEG does.
But then I learned that the PNG compression parameter just controlled how much compression for the algorithm to apply, trading longer save speed for decreased file size.
Given that PNG is a lossless format, is there any reason to still be using TIFF in this day and age? I still have many many images in TIFF format, but as I work on them I re-save as PNG…
I’ve never seen that the file format used for a pixel image when losslessly saved matters.
If you switch to PNG you’ll probably save disk space for most images, and it becomes obvious if a file is new/recent or old, and since it is a nicely documented format, you get out of the morass of the ambiguity of obscurity of TIFFs and the potential incompatibilities thereof.
The only thing I can think of which would specifically justify TIFF would be a multi-page scan.
I would say no. There might be small practical reasons, but they’re small. The bigger reason is that some tools output a TIFF, so it’s easier to be able to load them directly.
