OCR First: When a Scan Needs a Text Layer
OCR adds a real text layer behind the page image, so a scan can be searched, copied and converted without changing how it looks. It is usually the step before another tool, not the final destination.
Why this comes up
Scans enter a workflow looking complete, then fail at the first search, conversion or filename pattern. Recognising the text early avoids repeating the same job on a file that was never readable to begin with.
Check before you run it
- Confirm the page is actually a scan. If text cannot be selected in a viewer, OCR is needed. If it can, run the text or conversion tool directly and skip the extra pass.
- Match the language and engine. Language is a Tesseract code such as eng, deu or fra. The standard engine runs in the browser; high accuracy uses Paddle models where available and is strongest for English and Chinese, while other languages stay on Tesseract.
- Straighten first and verify afterwards. Deskew a crooked scan before recognition, then search for a name, a date and a total. Proper nouns and figures are where OCR guesses most often.
When to reach for it
- A scanned contract must become editable Word text. OCR the scan first, then convert the searchable PDF; otherwise the .docx arrives as pictures or blank paragraphs.
- A folder of scanned invoices needs meaningful names. OCR gives Rename the text it needs to build a filename from the first page.
One question we get
Does OCR upload my scan?
No — recognition runs inside your browser (Tesseract), so the scanned content never leaves your device. The searchable PDF is built locally too.
Where it fits
The tools people usually open next to OCR:
- Rename — Change document filename based on text from the PDF pages
- Resize — Change PDF page size and add margins/padding.
- PDF to Word — Convert from PDF to DOCX online
Every tool works on a copy, so the original file is never touched. Uploads are stored under an unguessable id and deleted automatically two hours after you last open them; nothing is listed, shared or indexed. More on the security page.
