I have a bunch of ~200k tiff files. I open them in Photoshop, crop them so they are about 20% of the original size, do a save, and the resulting file is about 2Mb - nothing done to the file except cropping. How can they grow so much?

Hi

May be your problem in cropping.

If you put only number it will be crop in cm. So, you have to put number with px. Example 1169px

You can try this.

As I said previously, if I just open the file and do a "save as" (no cropping) and save compressed (exactly like you show) it still DOUBLES the size and takes way, way longer to do each file then just going to file>save

When you save a Tiff you have a choices of using data compression or not and if you want the file compressed which compression method should be used. What options did you use?

None - I just did file>save. No options came up.

So I just opened a file and did save as tiff. With either compression it still comes out to be twice as big doing nothing to the file except saving it in the exact same format.

When I cropped the pic so that it is about 20% of the original and save using compression, it is about the same size as the original.

Then what happened is you open a compressed Tif files cropped the image ans then saved an uncompressed tif file.
