Prefer selectable text
A scanned image-only PDF is harder to search, copy, translate, and read with assistive technology. Use OCR when the document is meant to be searched or archived.
After OCR, search for a few words from the file to confirm the text layer is usable.
Use structure when possible
Headings, lists, table headers, and logical reading order make long documents easier to navigate.
For exported documents, prepare the source file with real headings and clear tables before converting to PDF.
Check visual clarity
Use enough contrast, avoid tiny text, and make sure rotated pages are corrected. Accessibility starts with basic readability.
For official accessibility requirements, use the standards and tools required by the organization receiving the file.
Practical example workflow
Prepare a separate sharing copy before editing a PDF. Keep the original file private, then create a review copy for compression, merging, redaction, OCR, or upload-size adjustments.
Open the final PDF in a different viewer from the one that created it. Check page order, rotated pages, missing fonts, links, signatures, stamps, metadata, bookmarks, and whether text can be searched or copied when that matters.
Quality checks before sending a PDF
If the PDF contains personal, financial, medical, school, or client information, remove unnecessary pages and use real redaction instead of covering text visually. Search for redacted words after saving to confirm they are gone.
For official submissions, keep a full-quality archive copy and a smaller upload copy with clear filenames. If a portal has file-size or format rules, check those rules before the deadline rather than compressing repeatedly at the last minute.
