How to convert multiple XCF files to PNG?

Question

I have a folder with a lot of xcf files which I want all to be converted to png files, at best via a one-liner from bash.

How can I achieve such a task?

Solution 1

One-liner from bash:

for i in *.xcf; do xcf2png -f $i -o $i.png; done

Solution 2

You can use GIMP Image editor and use Export to tool. Use Ctrl-Shift-E as shortcut.
Or you could use convert from imagemagick:

convert filename.xcf filename.png

You could also use xcftools (sudo apt-get install xcftools), which has a utility called xcf2png that does this job perfectly.

xcf2png image.xcf -o image.png

Solution 3

same of @k0pernikus, but remove xcf extension from output filename

for i in *.xcf; do xcf2png -f $i -o "${i%.*}.png"; done

Solution 4

My one-liner using convert from imagemagik:

for i in Amplicon*.xcf; do convert $i ${i/xcf/png}; done

I had to keep my 'Amplicon' name because otherwise, it finds hidden xcf files in the directory and exports all the layers as individual PNGs haha. But it works! And the variant not using a loop (and could be parallelized)

find . -name "Amplicon*xcf" | xargs -I {} convert {} {}.png

But... I coudn't remove the '.xcf" from the filename. Still works!

Solution 5

Based on J. Auger's solution:

find . -name "Amplicon*xcf" | parallel convert {} {.}.png

With xcf2png...

@jasonwryan Thanks, worked like a charm.

You may want to give a try to convert tool from ImageMagick. Supports a lot of formats and operations, might be useful in future.

does not work for xcf created by new gimp2, this tool is too old
