After much searching, this is the only FREE tool that exports a PDF with copyable text that worked for me. CopyDoc Text Kit also works, but it costs around 30 dollar/euro per month after the first 15 uses.
Free PDF Image Compressor
Note: If you have any links in your PDF, they will be exported with border around them. This is also a problem with the native Figma PDF export. It can be solved by doing the following:
Removing strokes from invisible links:
· Export PDF from Figma.
· Open PDF with TextEdit (free app on mac)
· Cmd-F to search for “/Link” (don’t include quotes)
· Check box in upper right “replace”
· In the replace field paste “/Link /Border [0 0 0]” without quotes.
· Click on the “all” button on the right side.
· Click on the “done” button.
· Save.
· Open file in acrobat to verify it still opens (it should)
· All links are now invisible but still present.
Alternatively this can be done programatically in the terminal
I successfully used the following script:
LC_CTYPE=C LANG=C sed ‘s|/Link|/Link /Border [0 0 0]|’ “FILENAME.PDF" > “FILENAME_NOBORDERS.PDF"

Let me know if anything is unclear. I really hope that helps and that it works for you too!
