OCR PDF, free in your browser
You can make a scanned PDF searchable here in your browser: open the document and the tool reads the text with on-device OCR, then adds an invisible, selectable text layer over each page - so the file looks identical but you can now search, select, and copy its text. The scan is processed on your own device, never uploaded, with no sign-up.
How to OCR a scanned PDF
- Open your scanned PDF.
- Click “Make searchable” - OCR runs on each page in your browser.
- Download the searchable PDF; its text is now selectable and searchable.
Limits & good to know
- OCR adds a searchable, selectable text layer over each page and keeps the original exactly as it looks - it does not rebuild the scan into editable fonts, tables, or form fields.
- Recognition accuracy depends on the scan: clear, straight, high-contrast text works best, while faint, skewed, or handwritten text may be missed.
- English text is supported; the recognition engine (about 6 MB) downloads to your browser once on first use, then works offline.
- It runs on your device, so a long document can take a few seconds per page and is limited by available memory, not an upload.
- A password-protected PDF must be unlocked before OCR.
Frequently asked questions
- Are my files uploaded to a server?
- No. TrulyFreePDF runs entirely in your browser - your file is opened and processed on your own device and is never uploaded, stored, or shared.
- Does OCR change how my PDF looks?
- No. Each page keeps its exact original appearance; OCR only adds an invisible text layer on top, so you can select and search the text while the scan looks identical.
- Can I edit the text after OCR?
- OCR makes text searchable and selectable, not reflowable. To change wording, use the Edit PDF tool, which can retype text on a scanned page. OCR does not convert a scan into fully editable fonts or tables.
- Is this really free, or free "until you hit a limit"?
- Really free. Unlike most "free" PDF sites there is no task-per-day cap, no locked Pro features, no watermark stamped on your file, and no payment step before download. Every tool is the full tool.
