  2. Select grayscale or threshold mode and adjust the threshold if needed.
  3. Review small letters, names, and numbers in the PNG before downloading.

What to know

Designed for text scans. Use the colour certificate enhancer when colour seals matter. An aggressive threshold may erase faint letters, and missing text cannot be recovered. Limits: 20 MB and 20 megapixels. Keep the original image.

Frequently asked questions

What is the difference between grayscale and threshold?

Grayscale keeps shades of grey. Threshold makes strong black and white, which can remove faint letters.

Can it recover blurred text?

No. A clear source image is essential; this cannot reconstruct missing detail.

Is my file uploaded?

No. Processing runs in the browser.
