Best image settings for OCR

Supported types and limits, plus quick capture tips.

Which image types work best?

Use clear JPEG, PNG, WebP, HEIC/HEIF, AVIF, TIFF. JPEG is a safe default; HEIC/HEIF are supported.

What size and dimensions are allowed?

Up to 10MB and 8,192×8,192 pixels per image. We may shrink very large photos to up to 2,560 pixels to speed things up.

How many images can I upload at once?

Up to 12 photos at once.

Any capture tips?

Good light, no glare, fill the frame, avoid skew. Printed, high‑contrast text works best.

Can I upload PDFs?

No. Please export a page as an image (JPEG/PNG) or take a clear photo.

My phone saves HEIC; how do I convert to JPEG?

On iPhone: Photos → Share → Save as JPEG. On Android/Windows: use “Export” or “Save As” to JPEG in your gallery/photos app.

We delete uploaded images after processing.
