Acrobat Troubleshooting: Cannot Edit, Still Too Large, Text Not Selectable, Format Drift

Quick answer: Most Acrobat "problems" are PDF format traits, not software faults. Diagnose by symptom: no text layer, permission restrictions, or image-dominated file size — then pick between the Acrobat fix and a free alternative. Open PDF Edit & Annotate — everything runs locally in your browser, and files never leave your device.

Steps

1. Cannot edit: permission password (enter it or ask the sender), scan without text layer (OCR first), or expired subscription (free paths per task).
2. Still too large after compression: the size lives in already-compressed images — downsample scans, split out needed pages.
3. Text not selectable: no text layer — run OCR (Acrobat Scan & OCR or DocsAll OCR).
4. Format drift after conversion: inherent to coordinate-fixed PDF — verify two-column/table areas, prefer source files when available.

Important notes

• The universal 3-step diagnosis: text layer? permissions? size composition?
• Almost none of these are Acrobat bugs — understanding the format dissolves most complaints.

Common questions

Why does compression barely help? Already-compressed image objects have little left to give; target the scans and the page count instead.

Where do free alternatives actually fit? Everywhere except true in-place text editing, form authoring, batch actions, and certificate signing — stated per task in the alternatives guide.
