Common Image Problems That Hurt Text Extraction and How to Fix Them

If the output is empty or messy, the source image is usually the limiting factor. Fixing the file almost always helps more than retrying the same upload.

Blur

Retake the photo or rescan the page. Sharpening filters rarely restore missing letter detail.

Glare

Move the light source or change the angle. White hotspots on glossy paper can erase letters entirely.

Perspective skew

Capture the page straight-on or deskew it before upload. Heavy perspective distortion breaks line spacing and word shapes.

Busy backgrounds

Crop closely around the text region. Decorative backgrounds add noise that turns into random punctuation and broken words.
