: What is the easiest way to reduce the file size of a TIFF without losing too much of the image's quality? I have a few high res TIFF files I'd like to reduce in size as they are currently

@Samaraweera207

If you have uncompressed TIFFs and work on a Mac, you can batch compress them in Terminal with tiffcp -c lzw "INPUT_FILE" "OUTPUT_FILE"

I just did this, to compress a big folder of tiffs, with additional commands to preserve the original modification time on the files:

for f in *.tif *.tiff; do out="$f.lzw.tiff"; if tiffcp -c lzw "$f" "$out"; then touch -r "$f" "$out" && mv "$out" "$f"; else echo "ERROR with $f"; fi; done


Or a more readable multi-line version:

for f in *.tif *.tiff; do
out="$f.lzw.tiff";
if tiffcp -c lzw "$f" "$out"; then
touch -r "$f" "$out" && mv "$out" "$f";
else
echo "ERROR with $f";
fi;
done


(tiffcp comes with the libtiff homebrew package. So you need to have homebrew installed, but if you are lazy enough you probably already have it)

I would resave the TIFF file with LZW compression turned on. That should get the size down considerably.



Edit:

If you are using Photoshop, you would simply "Save As", choose .TIF as your format and location.

After that you should get a dialog box (see below) with compression options.
