Quick answer
What is OCR PDF used for?
Purpose
What does OCR PDF do?
Expect a new PDF with a text layer when recognition succeeds. Search for a known phrase to check the result.
Who normally uses it?
This guide is useful for people searching, comparing, recognizing, completing, or inspecting document information. The working tool is focused on one outcome: Make a scan searchable. Small jobs stay on your machine.
Prepare
Before you start
- Determine whether the document has a text layer or is an image-only scan.
- Keep the original available while checking extracted text, differences, fields, or metadata.
- Treat uncertain recognition and layout results as items to verify rather than final facts.
Worked example
Make a photographed typed memo searchable.
This example describes a practice task, not a document you need to upload to us. Use your own authorised file and keep the original.
- 01
Prepare the example
Choose a legible English-language scan. The current OCR release recognises English only.
- 02
Make the change
Run OCR and inspect the recognised words against the page image, including names and numeric values.
- 03
Check the result
Expect a new PDF with a text layer when recognition succeeds. Search for a known phrase to check the result.
When the result is not right
Troubleshooting OCR PDF
For poor recognition, start with a sharper, straighter English scan. Use a compatible recognition service for other languages, and verify important values against the image.
Before you rely on the output
Skew, blur, handwriting and language mismatch affect accuracy. Searchability does not imply transcription accuracy.
Open the saved result as well as the preview. Keep the original until you have checked the pages and information that matter for your task.
Better results
Practical tips for OCR PDF
Use OCR first when text search or extraction cannot see words that are visible on the page.
Review warnings and confidence notes before relying on extracted or compared information.
Check names, dates, totals, identifiers, and form answers against the page itself.
Honest expectations
Limitations and important checks
OCR accuracy depends on language, resolution, contrast, page angle, handwriting, and scan quality. Important text must be checked against the page.
Questions and answers
OCR PDF FAQ
Direct answers to the questions people commonly ask before using this tool.
What is OCR PDF used for?
OCR PDF is a browser-based Filozy tool built for this task: Make a scan searchable. Small jobs stay on your machine. It runs on this device, creates a separate result, and does not require an account or document upload.
Can I use OCR PDF on a phone or tablet?
Yes. OCR PDF works in a current mobile browser. Complex PDFs can need more memory, so keep the tab open, avoid switching apps during processing, and inspect the result before closing the page.
Does OCR PDF upload my file?
No. The selected file is opened and processed by code running in this browser tab. Document bytes and filenames are not sent to Filozy.
Will this change my original file?
No. Browsers cannot silently overwrite the file you selected. Filozy creates a separate result for you to save or pass to another local tool.
What should I check after using OCR PDF?
Check the visible preview and the result summary. The OCR engine is downloaded only when requested and processes small jobs locally; recognition quality still depends on the scan. Keep the original until the new output has been opened and verified.
Do I need an account or subscription?
No account is required for this browser-side tool. It runs on the device and does not use a document-upload allowance or daily server quota.
Privacy
Where does my document go?
For this tool, the document stays in the browser tab. Filozy can load same-origin support files such as its PDF engine, fonts, or OCR data, but the selected document bytes and filename are not sent with those requests.
