A practical starting point
For a scanned file, run OCR before extracting text. For a damaged or encrypted file, repair or decrypt it before another operation. For a large document, test a short page range first.
Browse the complete AmrrkPDF library by task. Start with the smallest operation that solves the problem, then verify the downloaded result.
Use conversion tools when the output format must change, editing tools for visible page changes, merge and split tools for page structure, and security tools for passwords or metadata.

Memory use depends on page count, image resolution, fonts, and document complexity. Close unused tabs and keep the original file before processing a large document.
Keep the source file, open the output, and review its pages, text, images, links, and forms before sharing it.
