Image to Text (OCR)
Upload a photo or screenshot and AI extracts all text into editable format.
Image to Text
Upload an image to extract text with AI
Upload image or scanned PDF
Drop in a JPG, PNG, TIFF, or scanned PDF. Supports single and multi-page documents.
AI runs OCR
Our AI recognises printed text, typed content, and even handwritten notes with high accuracy.
Copy or download text
The extracted text appears instantly. Copy to clipboard or download as a .txt file.
Why SynthPDF?
AI-powered OCR
Not just pattern matching — our AI understands document layout, handles mixed text orientations, and recognises text in complex backgrounds.
Handwriting supported
Extracts clear block printing and typed handwritten notes. Accuracy depends on legibility — printed text achieves 98–99% accuracy.
Phone photos work
Take a photo of a document with your phone camera and upload directly. As long as the image is in focus and well-lit, extraction is highly accurate.
Multi-language OCR
Supports all major Latin scripts, Cyrillic, Arabic, Chinese, Japanese, Korean, Hindi, and Greek — with automatic language detection.
Multi-page scanned PDFs
Upload a scanned PDF and every page is processed in sequence — the full extracted text is combined into a single downloadable output.
Free, no account needed
5 AI uses per day on the free plan. Pro gives 15/day, Max gives 100/day, UltraMax is unlimited.
What Is OCR and Why Does It Matter?
OCR (Optical Character Recognition) converts images of text into actual, selectable, searchable, editable text. Before OCR, a scanned document was just a photograph — you couldn't search it, copy from it, or feed it to any text processing system.
AI-powered OCR (what we use) goes further than traditional OCR libraries: it understands document layout, handles multiple text orientations, and recognises text in complex backgrounds and mixed-language documents.
Supported Input Types
- Scanned PDFs — PDFs where every page is an image (no selectable text)
- Photos of documents — taken with a smartphone camera
- Screenshots — from any source (desktop, browser, app)
- JPG, PNG, TIFF, WebP images — single-image files
- Handwritten notes — clear block printing extracts well; cursive is partially supported
Factors That Affect Accuracy
- Resolution (DPI) — 150 DPI minimum, 300 DPI recommended. Phone camera photos at full resolution are typically sufficient.
- Lighting — even lighting with no shadows across text. Glare from glossy pages can reduce accuracy significantly.
- Angle — documents photographed at an angle (keystoning) produce lower accuracy. Photograph straight-on or use automatic perspective correction.
- Font — standard printed fonts: near-perfect accuracy. Decorative, cursive, or heavily stylised fonts: reduced accuracy.
- Background complexity — text on plain backgrounds extracts perfectly. Watermarked, patterned, or coloured backgrounds reduce accuracy.
After Extraction: Recommended Next Steps
- Check grammar — OCR occasionally introduces errors in similar-looking letters (I/l/1, O/0). Run through Grammar Check to catch these.
- Extract structured data — if the image contained tables or forms, useExtract Data for structured CSV/JSON output.
- Translate — extracted text from foreign-language documents can go directly into our Translate PDF tool.
- Create a searchable PDF — use AI Chat with PDFon your original scanned PDF after confirming text quality with the OCR extraction.
Frequently Asked Questions
Yes — AI OCR handles clear handwriting. Heavily stylised or very messy handwriting may have lower accuracy.
JPG, PNG, TIFF, WebP, and PDF (scanned). Multi-page PDFs are processed page by page.
For clean printed text, accuracy is typically 98–99%. Blurry or low-resolution scans will reduce accuracy — use at least 150 DPI for best results.
Yes — as long as the image is in focus and reasonably well-lit, phone photos work well.
The extracted text preserves paragraph breaks and line structure. Complex multi-column layouts may need manual adjustment.
