Cómo Usar
- Upload Your PDF: Drag any PDF in. Works best with scanned documents that have inconsistent borders — typical when documents come from mixed sources (flatbed scans, phone cameras, faxed forms).
- Pick Trim Mode: Three options: (1) Auto-trim to content — finds the tightest rectangle around all content; (2) Symmetric inset — removes equal margin from all sides; (3) Asymmetric — separate left/right/top/bottom trim amounts. Per-page or all-page modes.
- Preview: See the trim zone overlay before applying. Adjust if the auto-detect caught too much or too little. The preview updates live as you tweak values.
- Save: Click 'Trim' and save the compact PDF. Pages are uniformly tighter, ready for clean printing, email-friendly sharing, or consistent e-reader display.

Preguntas Frecuentes
How do I trim whitespace from a PDF?
Open our PDF Crop tool, drop your PDF, choose 'Auto-trim' (smart whitespace removal) or set specific insets, preview the result, and save. The trimmed PDF has tighter page bounds — no upload, fully local processing.
Will auto-trim accidentally remove content?
Auto-trim only removes whitespace based on visual content boundaries. It identifies the bounding box of all text/images on the page and trims to that edge (with a small configurable safety margin). For documents with content extending close to page edges, set a small symmetric inset to ensure safety. Always preview before saving.
Can I trim scanned PDFs cleanly?
Yes — this is exactly the use case our tool targets. Scanned PDFs often have inconsistent borders due to multi-pass scans, photocopy chains, or different paper sizes. Auto-trim normalizes them all to the content boundary, giving you uniformly tight pages.
Does it preserve annotations and form fields?
Annotations respect the new page bounds (visible only where they fit). Form fields stay in the document but are clipped to the new view if they extend beyond. Preview the trim to spot these issues before saving — adjust to be more conservative if needed.
Will my PDF be uploaded?
No. pdf-lib runs entirely in your browser. Trimming is just page box updates — content, layout, fonts, and images stay exactly where they were. Useful for sensitive scans like medical records or legal exhibits.
