How to Convert WebP image to Gif with Python?

Question

I already tried this:

from PIL import Image
im = Image.open('this.webp')
im.save('that.gif', 'gif', save_all=True)

which is giving me this error

TypeError: unsupported operand type(s) for &: 'tuple' and 'int'

I have hundreds of webp images on my site and need to convert them to gif, because Firefox doesn't support it. Thank you.

Which version of pillow are you using: I would suggest you to see this issue: https://github.com/python-pillow/Pillow/issues/2949 — user2906838, Aug 25 '18 at 10:49
I downgraded pillow from 5 to 4.3.0. It fixed the issue. Now the problem is the animations are gone. — Azimjon Pulatov, Aug 25 '18 at 10:53

Please provide a WEP file that doesn't work for us to test with. — Mark Setchell, Aug 25 '18 at 12:14

Set background to None before saving.

from PIL import Image
im = Image.open('this.webp')
im.info.pop('background', None)
im.save('that.gif', 'gif', save_all=True)

is it possible to increase the quality of the resulted gif ? – Feraru Silviu Marian Sep 08 '21 at 16:23
@FeraruSilviuMarian Yes probably. You should check the documentation of the pillow package. – muratgozel Sep 08 '21 at 16:53
Been doing it for hours to no avail – Feraru Silviu Marian Sep 09 '21 at 03:25
the saved file is using less colors it seems – Feraru Silviu Marian Sep 09 '21 at 03:27
@FeraruSilviuMarian i don't remember the process right now but it may be because of the default options. – muratgozel Sep 09 '21 at 10:49

@muratgozel Thanks! Also take into account the possibility of a better transformation quality by setting these extra options: `im.save(str(sys.argv[1]).replace('webp','gif'), 'gif', save_all=True, lossless=True, quality=100, method=6)`.
