Question

Hello, I try to download the thumbnails files in png/jpg format but they are always downloaded by default in webp format. I’m inserting this code in cmd:

youtube-dl --write-thumbnail [URL playlist]

The files are downloaded directly to the computer in webp format

I tried to add -f:

youtube-dl -f --write-thumbnail [URL playlist] But it still wouldn’t let me choose the format I wanted.

I know there’s an commend called:

--write-all-thumbnails But I don’t understand why you can’t choose to download in jpg/png format At the end of the day, it’s the same quality.

For example: https://i.ytimg.com/vi_webp/HOYDj769s6k/maxresdefault.webp

https://i.ytimg.com/vi/HOYDj769s6k/maxresdefault.jpg

It’s the same picture with a different extension.

I’ve seen a report on it before and it’s closed, but I didn’t understand the solution.

Can someone explain to me where I’m wrong?

you can always use dWebP from the Google’s WebM project #1 #2, or ffmpeg (which I think is already used in ytdl anyway…), to convert the thumbnail to whatever format that works best for you.

With FFmpeg (Unix commands):

To .jpg: for i in *.webp; do ffmpeg -i "${i}" -q:v 1 -bsf:v mjpeg2jpeg "${i%.webp}.jpg"; done

To .png: for i in *.webp; do ffmpeg -i "${i}" "${i%.webp}.png"; done

Thanks guys!

I’ll check it out. Suggestion I Considered an Increase: Add an option to choose which format to download thumbnails as can be done with video I mean it: youtube-dl -f 'bestvideo + bestaudio / bestvideo + bestaudio' --merge-output-format mp4 [URL]

And turn it into something like this:

youtube-dl.exe --write-thumbnail [ext = jpg/png] --skip-download --output "%(title)s.%(ext)s" [URL HERE]

yt-dlp.exe --skip-download --write-thumbnail --convert-thumbnails jpg

Thank you very much bro you helped me! I did not even know that yt-dlp exists. Thanks
