Gonna be honest, never used ffmpeg for images lol. I often take images from PDFs that have transparency (rpg books to import into my vtt) and they come out of pdfimages with an opaque greyscale alpha mask and an opaque image. I found it easy to apply the mask with imagemagick, though. Ffmpeg can probably do it but just never had a use case. I just use cwebp to convert because that’s my primary use-case: converting pngs to lossy webp files and cwebp is good enough for me for that:)
Usually what i do is look for any converter and look for open source alternatives to it on alternativeto.net and hopefully one of the top 3 alternatives fits your use case
Psst the URL is:
https://alternativeto.net/
I always stop here first to research what software options there are available and also learning what other people are using. Extremely useful and trustworthy site!
Yes this can also happen. I should have written open source offline converter
What you recommend in terms of offline open-source converters?
Pandoc for documents, ffmpeg for video , imagemagick for images
What image types are you using that ffmpeg can’t convert? To my knowledge it works for almost anything.

Images from PDFs, wasn’t thinking about that. I normally work with just image files. Cool!
