How to Use OCR PDF
OCR PDF is built for people who need to make scanned PDF text searchable without installing desktop software. It works in the browser and keeps the workflow focused: upload the right file, choose the available options, process the document, and download the result.
This guide walks through the practical steps, explains what files to prepare, and lists the small checks that help you avoid failed uploads or confusing output.
When to use OCR PDF
Use OCR PDF when you have one scanned PDF and need a searchable PDF. It is especially helpful for scanned contracts, receipts, archived documents.
For the best experience, start with the clearest source file you have. If a document is password protected, damaged, scanned at low quality, or very large, fix that issue before processing whenever possible.

Tips for better results
A few seconds of preparation can save time later. Check the source file before uploading, confirm that it opens correctly on your device, and make sure the selected iZipPDF tool matches the file type.
- Use clear scans.
- Straighten pages before OCR.
- OCR works best with readable printed text.
Common problems
If processing fails, try the file again in a fresh browser tab. If it still fails, test a smaller file, clear the browser cache, or use Repair PDF when the source document appears damaged.
- Handwriting is hard to recognize.
- Low-resolution scans reduce accuracy.
- Rotated pages may need correction first.
Before you share the finished file
- Open the downloaded file and review the first and last page.
- Check page order, orientation, text readability, and file size.
- Rename the file clearly so the recipient knows what it contains.
- Use Protect PDF if the document contains private information.
