4chan’s guide to converting GIF to WebM - https://boards.4chan.org/g/res/41212767
Grab ffmpeg from https://www.ffmpeg.org/download.html
It's a command line tool which means you will have to type things with your keyboard instead of clicking on buttons.
The most trivial operation would be converting gifs:
ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm
-crfvalues can go from 4 to 63. Lower values mean better quality.-b:vis the maximum allowed bitrate. Higher means better quality.

Use this static class to extract Text from Pdf files.
It supports compressed and uncompressed Pdf (version 1.1 to 1.7) : tested
It supports octal encoded (eg : \050) content, but not hexadecimal (eg : <005E>).
In some cases, it works better than "pdftotext" binary tool.
