Overview
Searchable PDFs make it easier to find words inside scanned notes, documents, and printed pages. OCR, or Optical Character Recognition, reads visible text and adds a searchable text layer to the PDF.
Why this matters
Students can locate topics faster in long notes, but OCR accuracy depends heavily on clear handwriting, scan quality, language, and page layout.
Start with clear scans
OCR works best when pages are straight, bright, focused, and written in clear dark ink. Avoid shadows, folded pages, decorative backgrounds, and very small handwriting.
For handwritten notes, print-like handwriting is usually recognised better than joined cursive writing.
Use OCR carefully
Upload the scanned PDF to OCR PDF and create a searchable version. The visible page image remains, while searchable text is added behind it.
OCR may misread unusual handwriting, formulas, tables, diagrams, names, and mixed languages. Treat the result as a study aid, not proof that every word is perfect.
Keep the original scan
Always keep the original PDF. If OCR makes an error, the original visible handwriting remains the reliable reference.
Use meaningful names such as Physics-Notes-Chapter-4-Searchable.pdf so the file is easy to find later.

Important note
Always review downloaded documents before submitting, printing, signing, or sharing important files. Complex formatting, scanned pages, images, fonts, or document protection can affect processing results.
