Image to Text (OCR)

Turn screenshots, scans, and photos of print into editable text — free, with the Tesseract OCR engine running as WebAssembly inside your browser. No cloud vision API is involved: the engine downloads to your device, your image never leaves it, and the text arrives with a copy button and a .txt download.

How to extract text from an image with Allypdf

  1. Drop in one or more images containing text.
  2. Pick the document's language — it noticeably improves accuracy.
  3. Run the recognition; progress is shown live while OCR works on your device.
  4. Copy the extracted text straight from the panel, or download it as a .txt file.

Why "no upload" matters here

The images people OCR are dense with sensitive data by definition: receipts, invoices, ID cards, contracts, prescription labels, screenshots of private conversations. Most online OCR tools forward those to a commercial cloud vision API. Allypdf refuses that trade: the recognition engine is downloaded to your browser and the entire read happens on your own hardware — no Google Vision, no Textract, no server ever sees the image.

Common uses

  • Digitize a receipt or invoice so the numbers can be pasted into a spreadsheet.
  • Pull a quote or reference out of a book photo without retyping it.
  • Recover text from a screenshot when the original document is gone.
  • Extract an error message from a screenshot to search or report it.

Frequently asked questions

How do I copy text from an image?

Drop the image onto Allypdf's Image to Text tool, click Extract Text, and press Copy Text on the result panel — the recognized text is on your clipboard. You can also download it as a .txt file. Free, no sign-up, no watermark.

Does this use Google Vision or another cloud OCR API?

No — deliberately. The Tesseract OCR engine runs as WebAssembly inside your browser, so the image is never uploaded to any server or third-party API. The only downloads are the engine and language pack themselves, fetched once and cached.

How accurate is it?

It works best on clear, high-contrast text: crisp screenshots, scans, and well-lit photos of print. Accuracy drops on blurry, skewed, or handwritten images and heavily stylized fonts. Choosing the correct document language makes a noticeable difference.

Which languages can it read?

English, Spanish, French, German, Italian, Portuguese, and Dutch. Select the language before running — the matching recognition model is downloaded on first use and cached for subsequent runs.

Can I extract text from multiple images at once?

Yes. Add several images and they are recognized one after another with live progress. Each gets its own text panel with a copy button, and the .txt files download together as a ZIP.
