FAQ

  • Is Stirling PDF a replacement for Adobe Acrobat?

    For most operations yes — merge, split, OCR, compress, convert, sign. It doesn't match Acrobat's advanced form editing.

  • Which has better OCR?

    Both use Tesseract OCR. Quality depends on your Tesseract language packs. Stirling PDF makes it easier to configure OCR languages.

  • Can I use these without Docker?

    Yes. Both have Java/Direct binaries available. Docker is the easiest setup method.

  • Are my PDFs safe on these tools?

    Both run locally and process files on your server. No files are sent to external services. Stirling PDF can be configured to delete files after processing.
