Extract text from TIFF and TIF images from professional scanners, archival records, medical documents, and publishing workflows. TIFF's lossless quality means no artefacts, no blurring, maximum OCR accuracy. Supports 15 languages. All processing happens in your browser — your files are never uploaded.
Upload your TIFF or TIF file
Drag and drop your TIFF image onto the drop zone, or click Browse files to select one. TIFF files from flatbed scanners, document management systems, medical imaging software, and publishing applications are all supported. Note that TIFF files from professional scanners can be large — if your file exceeds 10 MB, reduce the scan resolution and re-export before uploading.
Select the language of the text
Use the language selector to choose the language of the text in the document. Up to 3 languages can be selected simultaneously for multilingual content. For scanned documents with mixed languages — common in archival and legal files — selecting all relevant languages significantly improves accuracy.
Enable Grayscale for colour scans
Professional scanners often produce full-colour TIFF files even for black-and-white documents. Enabling Grayscale under Image Enhancement strips colour information and can improve recognition speed and accuracy, particularly for documents scanned with coloured backgrounds or yellowed paper.
Adjust Contrast for aged or faded documents
Archival TIFF scans of old documents — contracts, books, historical records — often have faded ink or yellowed paper that reduces contrast between text and background. Try Subtle Contrast first; for heavily faded documents use Strong. All enhancements run locally and do not modify your original file.
Wait for recognition to complete
The progress bar shows two phases: downloading the language data file (first time only — cached by your browser afterwards) and running OCR. High-resolution TIFF scans may take slightly longer to process than compressed formats due to their larger pixel count.
Review, edit, and export the result
The extracted text is fully editable — correct any recognition errors directly in the text area. The confidence score is especially useful for archival documents: if it is below 65%, try adjusting Contrast or Grayscale and click Re-run. Use Copy or Download .txt to export the final result.
No — your TIFF file is never sent to any server, even for large high-resolution scans. All OCR processing runs entirely in your browser using Tesseract.js and WebAssembly; your image stays on your device and is never transmitted anywhere. This matters for TIFF files that often contain sensitive archival or medical documents.
The tool supports 15 languages: English, Russian, German, French, Spanish, Portuguese, Italian, Dutch, Polish, Simplified Chinese, Japanese, Korean, Arabic, Turkish, and Ukrainian. You can select up to 3 languages simultaneously — particularly useful for archival and legal TIFF documents that often contain mixed-language content.
TIFF supports lossless compression, high bit depths (up to 32 bits per channel), multiple colour spaces, and embedded metadata — all essential for archival, medical, and publishing workflows. Unlike JPEG, TIFF does not degrade with each save. Unlike PNG, it is natively supported by virtually all professional scanner software and document management systems.
The tool processes only the first page of a multi-page TIFF file. If your document has multiple pages, use a desktop tool such as ImageMagick or a free online TIFF splitter to extract individual pages, then upload each one separately.
Enable Grayscale and Contrast under Image Enhancement. Grayscale removes colour noise from yellowed paper or backgrounds. Contrast amplifies the difference between faded ink and the paper surface, making text edges sharper. For heavily faded documents use Strong Contrast; for slightly aged ones Subtle is usually enough. All enhancements are applied locally and never modify your original file.
For raw scanned documents, TIFF generally gives higher OCR accuracy because it stores uncompressed or losslessly compressed pixel data without the additional layers that PDFs can introduce. PDFs can contain compressed images that reduce quality, or mixed raster and vector content that complicates extraction. If you have a scanned PDF, consider extracting pages as TIFF for the most reliable text extraction.
Professional scanners often produce TIFF files at 300–600 DPI, which can exceed 10 MB for A4 pages. To reduce file size, re-scan at 200–300 DPI (still sufficient for accurate OCR), or open the file in an image editor and export as PNG — PNG compresses the data losslessly and is significantly smaller while preserving the same image quality.
