Free or inexpensice photo editor

[gwpriester]

I have used Photoshop for at least 20 years simply to convert a PNG with Alpha transparency to TIFF with the same transparency.

And to convert an image to grayscale.

Two things I have given up hope of ever seeing in Xara in my lifetime.

Photoshop CSS 5 however does not support 4K resolution. So my relationship with Photoshop has come to an end.

Any recommendations for a simple image editing app that can do these things?

Simple is better.

affinity photo has greyscale and will open a transparent PNG and export it as a 16bit greyscale TIFF with transparency

PNG created in xara:



imported into affinity and then exported as 16bit greyscale TIFF [zipped as TG does not like the format for upload]:

boxgs.zip

affinity is a one time purchase; you don't need affinity designer as well to do this, and has a free trial

[this is alpha-channel transparency, but I think that is all you get with TIFF ?]

Gary, maybe the free for personal use, installable/portable program XNviewMP , is something to look at.

haakoo - Perfect. Grayscale and TIFF with transparency. That's all I need.

Steve - Affinity would be perfect as well except I just need a simple straightforward way to do these two functions.

How do you save to your computer from Photopea? Oh, never mind, it seems to have saved to my desktop. Better solution because it can also do RGB to CMYK conversion.

sure gary, if xnview does the one task you need

when you install it though, be careful it does not take over image management tasks you use other programs for

don't know photopea; there are a lot of online converters though to choose from

Photopea does what photoshop does for general use which I think is fab.
