| | | Google tool for converting gifs to webp format. Handles animated gif to animated webp conversion--I needed a good way to do this after tumblr stopped auto-converting animated gifs to webp 'p', and the free online converters and even downloadable ones like XnView produce LARGER files rather than smaller ones.
gif2webp produces webp files smaller than the animated gifs you give them. Not sure how the free converters messed this up so bad.
Download (in a bundle with other webp utilities): https://developers.google.com/speed/webp/download
Usage: https://developers.google.com/speed/webp/docs/gif2webp
I made a bat file to convert any gifs in the folder (and subfolders, that's the /r switch I think) with it when it's double-clicked:
for /r %%i in (*.gif) do gif2webp -min_size "%%i" -o "%%~ni.webp"
(Supposedly the default compression level is 4 out of 6 but when I added -m 6 to switch to the highest compression level, the test file came out 1 KB larger. 'p') |

| | | | Hah you can't even upload animated webps to tumblr anymore. 'p' |
|
|
| | | | Okay with -m 6 a STATIC gif comes out as a VERY slightly smaller webp file than what I was getting with IrfanView (see entry 1991), so I'll use that setting for static conversions. |
|
|
| | | | Oops nope I misread it, IrfanView's conversion is very VERY slightly more efficient in terms of file size. |
|
|
| | | ^ To clarify, IrfanView has tended to give verrrry slightly (like, 0.01K or so) more compact file sizes (although not always; sometimes gif2webp wins--they also tie a lot) for STATIC webps; Irfanview still can't make/convert ANIMATED webps.

tumblr is allowing animated webps again. ; ) |
