Useful answers, clear tradeoffs, and sources you can check.
GoodLinks

Both decisions remain conditional on capturing your real sources and producing the output you need; neither is declared a tested winner here.

PDF Expert
Adobe Acrobat ReaderChoose PDF Expert for an Apple-focused document workspace with annotation and paid editing. Choose Acrobat Reader for basic reading, commenting and signing within the Adobe ecosystem, with paid mobile tools available separately. Match the exact platform and plan before paying.
PDF Extractor
iLovePDFPDF Extractor 1.01 returned four PNGs; iLovePDF 4.1.0 successfully returned three JPGs in the follow-up. The fixture contains three unique raster assets placed four times, so three outputs are consistent with resource deduplication, not a missing unique picture. Both retained the sample dimensions; neither returned transparency. PDF Extractor matched the RGB/scan reference pixels, while iLovePDF JPG pixels differed. This limited sample is not an overall ranking; no comparative winner is established.
TinyStudio
MacWhisperChoose TinyStudio for a focused Mac subtitle workflow. Choose MacWhisper when reviewing, reusing and exporting transcripts is a larger part of your work. TinyStudio’s Mac listing is free; MacWhisper offers Free and Pro editions. Neither positioning establishes an accuracy or speed winner.
