💡 Pro Tip

Use Sharpen conservatively on documents with small print — pushed too high, it can introduce noise around text edges instead of making the text more legible.

📖Document Enhancer Guide

Cleans up a phone photo of a document — crop it to just the page, straighten it, reduce uneven shadows/lighting, and sharpen it for a proper scan look.

When to use this

Use this right after photographing a document with your phone, before you need it to look like an actual scan — especially when the lighting was uneven or the shot wasn't perfectly straight.

Step-by-step workflow

  1. 1Upload your photo Choose the document photo you want to clean up.
  2. 2Crop to just the document Drag the corner handles to select just the page — this is a manual crop, so position it carefully rather than expecting automatic edge detection.
  3. 3Straighten and reduce shadows Use the Straighten slider for a crooked shot, and Reduce Shadows to flatten uneven lighting — this genuinely corrects the lighting gradient, not just a brightness bump.
  4. 4Choose a mode and fine-tune Color, Grayscale, or Black & White (with its own threshold slider); adjust Brightness, Contrast, and Sharpen as needed. Or just click "✨ Auto-Enhance" for a sensible one-click starting point.
  5. 5Download Your enhanced image downloads as enhanced-document.png, processed at up to 1800px on the longest side.

Tips for best results

  • ✓Reduce Shadows works especially well before switching to Black & White mode — flattening the lighting first makes the threshold conversion far more reliable on unevenly-lit photos.
  • ✓"✨ Auto-Enhance" is a genuinely good starting point (grayscale, moderate brightness/contrast/sharpen, and shadow reduction) — apply it first, then fine-tune from there rather than starting from scratch.
  • ✓Crop as tightly as possible to just the document — background clutter left in the frame won't benefit from the color/lighting corrections meant for the page itself.
  • ✓If you arrived here from Sign Documents's "try Document Enhancer" link, your photo is already loaded — enhance it, then use the "Continue to Sign Documents" button to go straight back and retry automatic extraction, no re-upload needed.

Common mistakes to avoid

  • ⚠Skipping the crop step on a photo with a lot of background visible — the enhancement adjustments are tuned for the document itself, not whatever surface it was photographed on.
  • ⚠Using Straighten to fix a photo that's sideways rather than slightly crooked — this is a fine-angle slider (±15°), not a 90°/180° rotation; use Rotate PDF's rotation for that instead if your file is a PDF, or re-crop and re-shoot for a badly sideways photo.
  • ⚠Expecting automatic shadow/edge detection for the crop and straighten steps — those two remain manual by design, so take a moment to position them carefully.
