Scanner beds leave grey borders. Presentations saved as PDF carry speaker-note margins. Cropping standardizes the viewport.

Search engines are full of “crop pdf” results, but most tools share the same hidden cost: your files leave your computer. BrainyPDF’s Crop PDF utility is a privacy-first alternative — free, unlimited, and 100% client-side.
Uniform crop across all pages
BrainyPDF crops every page by the same margin values — ideal for consistent scan cleanup. Set points or use presets, preview on thumbnails, export.
| Border type | Crop strategy | Workflow order |
|---|---|---|
| Grey scanner bed | Uniform margin trim | Crop → Compress |
| Speaker notes gutter | Wider bottom crop | Crop after final layout |
| Uneven mobile scan | Preview each thumbnail | Crop → Rotate if needed |
