How to Scan Documents for Better Text Extraction

Clean scans usually outperform casual photos because the page fills the frame, contrast stays consistent, and the text sits on a flat background.

Use enough resolution

Aim for a clear scan where small text still looks sharp when zoomed in. Tiny letters and low-resolution exports create broken characters and missing words.

• Prefer a document scanner or scanning app instead of a distant photo.
• Crop tightly around the page before uploading.
• Avoid exporting heavily compressed files when you need accurate results.

Keep the page flat and evenly lit

Shadows near the spine, curled paper edges, and uneven lighting make it harder to separate text from the background. Even light and a flat page improve line detection.
