Why OCR documents need compression
Phone photos of documents and flatbed scans often produce 3–10 MB files that exceed government portal upload limits. OCR systems (optical character recognition) need sufficient resolution for text detection — typically 200–300 DPI — but not full camera resolution. Compressing document images to target KB limits while preserving text sharpness is essential for successful portal submissions and OCR accuracy.
Compress document images for OCR
Photograph documents flat with even lighting and minimal shadow. Upload to our Image Compressor with quality 85–90 to preserve text edges. For strict KB caps, use target-size mode. Convert PNG scans to JPG for smaller files. Avoid over-compression that makes text blurry — preview before download. For multi-page documents, compress each page individually.

Will compression affect OCR accuracy?
Moderate compression does not affect OCR. Avoid aggressive compression that blurs text edges.
What format for document uploads?
JPG for photos of documents; PNG for high-contrast scans with fine text.
