OCR to Searchable PDF Online Free (Scans You Can Search)

OCR to PDF turns photos or scans of documents into a real searchable PDF. Each image becomes a page, and on-device OCR adds an invisible text layer so you can select words, copy them, and use Find in any PDF reader. Nothing is uploaded - recognition runs in your browser with the same Tesseract engine as OCR Image to Text. Clean, straight, high-contrast scans produce the best accuracy. Up to 15 images and 15 MB per file are supported.

Key benefits

• Produces a searchable PDF, not just pictures of pages.
• Runs entirely on your device - nothing is uploaded.
• Uses the same high-quality Tesseract OCR engine as OCR Image to Text.
• Works offline after the first engine download (~7 MB, cached).
• Free, no account and no watermark.
• Up to 15 images, 15 MB each.

How to use it, step by step

1. Add your images. Drop PNG, JPG or WEBP scans - one image per page, in order. Max 15 images.
2. Create searchable PDF. OCR reads each page, then builds a PDF with the image plus an invisible text layer.
3. Download. Open the PDF in any reader. Text should be selectable and searchable.
4. Proofread if needed. Check numbers and names against the original scan - OCR is excellent on clean print, not perfect on blurry photos.

Common use cases

• Turning phone photos of contracts into a searchable PDF archive.
• Making scanned homework or notes findable later.
• Preparing visa or bank packs that need one searchable file.
• Digitising paper receipts so expenses can be searched.

Pro tips

• Shoot pages flat, well lit, and fill the frame - skew and shadows hurt accuracy.
• Crop margins before converting when possible.
• Prefer 150–300 DPI scans over tiny screenshots.
• For an already-scanned PDF, use PDF to OCR instead of exporting pages first.

Common mistakes to avoid

• Expecting handwriting to OCR perfectly - printed text works best.
• Using a blurry angled photo and blaming the tool.
• Uploading a multi-page PDF here - use PDF to OCR for that.
• Skipping proofreading on numbers and names.

Frequently asked questions

How do I convert OCR / scans to PDF?

Add up to 15 images and create a searchable PDF. Each image becomes a page with an OCR text layer so words are selectable.

Is OCR to PDF free?

Yes. No account, trial limit or watermark. Processing runs in your browser.

Is my image uploaded?

No. OCR and PDF building run entirely on your device.

Will the PDF be searchable?

Yes. Recognised words are placed as an invisible text layer aligned to the scan, so Find and copy work in normal PDF readers.

How accurate is the OCR?

Clean printed scans are typically very accurate. Blurry, skewed or low-contrast photos produce more errors - always proofread important numbers.

What image formats are supported?

PNG, JPG and WEBP. Max 15 MB per image and 15 images per PDF.
