Pro Tips & Best Practices for Getting Optimal Results

Actionable advice to maximize document quality and processing speed.

To achieve the best possible result when using our online tools, consider these helpful guidelines:

  • Check page orientation (portrait vs. landscape) before finalizing conversions or file merging.
  • If sending output files via email, compress the final document using Compress PDF to keep file sizes small.
  • For image-only scanned PDFs, run OCR PDF first so text becomes selectable and copyable.

💡 Pro Tip: Always keep a backup copy of your original source files. If your document is password-protected, unlock it first using Unlock PDF before performing multi-file operations.
