I have too many images to search at visually, so I cannot open each one of them individually.

What I have to do or install to show DDS images previews on nautilus?

I would like to preview webp too if possible.


create files at /usr/share/thumbnailers with these names and content:

from here:


[Thumbnailer Entry]
Exec=/usr/bin/convert -thumbnail x%s %i png:%o

based on this:


[Thumbnailer Entry]
Exec=/usr/bin/dwebp %i -scale 100 100 -o %o

and restart nautilus after fully quitting it with nautilus -q

Obs.: the problem with this webp approach is that all thumbnails will be 100x100. But this script makes it work properly.

    If you replace the 100 with %s you'll get the appropriate size. Like this: Exec=/usr/bin/dwebp %i -scale %s %s -o %o – Liminal Jun 4 '16 at 11:09
  • @Liminal I had to update it to mime image/webp and I tested -scale %s %s but that was also giving me squared thumbnails of 256x256. On the other hand, the script calculates and gives the right proportional thumbnail size for x or y. ubuntu 16.04 here – Aquarius Power Aug 31 '17 at 1:25
  • There is a missing step here. You have to delete all cached thumbnails for Nautilus to be able to generate them again: rm ~/.cache/thumbnails/fail/gnome-thumbnail-factory/* rm ~/.cache/thumbnails/large/* rm ~/.cache/thumbnails/normal/* killall nautilus – Pere Joan Martorell Nov 29 '18 at 19:34
  • @pj.martorell interesting, I really dont remember having to do that, but apparently I probably did xD, btw, it could also be nautilus -q – Aquarius Power Nov 30 '18 at 20:25
