# Crop PDF Pages

> Trim white margins and excess space from PDF pages with draggable handles or exact numeric inputs — apply one crop everywhere, or switch to per-page mode for scanned books with mixed odd/even margins. The visible page box gets rewritten via pdf-lib; bookmarks, hyperlinks, form fields, and PDF/A or PDF/X compliance flags survive unchanged. Runs locally.

## How it works

1. **Select PDF** — Drop the PDF you want to trim, or click to choose a file
2. **Set crop area** — Drag the crop handles or enter exact margin values
3. **Download** — Download your cropped PDF instantly

## FAQ

### Can I crop different pages differently?

Yes. You can apply the same crop to all pages or set individual crop areas per page.

### Does this preserve bookmarks and form fields?

Yes. Cropping changes the visible page box; bookmarks, hyperlinks, form fields, and annotations all keep their anchors.

### What PDF versions are supported?

PDF 1.0 through 2.0 (including PDF/A-1, A-2, A-3 and PDF/X). Cropping does not change the version flag.

## Tips

- **Same crop everywhere, or per-page** — Apply one crop to all pages with the handles, or switch to per-page mode when scanned books mix even and odd margins.
- **PDF/A and PDF/X flags survive** — Cropping rewrites the visible page box without touching the version flag, so archival PDFs stay compliant downstream.
- **Drag handles or type exact margins** — Visual handles for eyeballing, numeric inputs for repeatable jobs — pick whichever matches your tolerance.

## Privacy — what we do not do

This tool runs entirely in the browser via WebAssembly. Your file never reaches a Loft Tools server. Specifically:

- **No upload.** The file bytes load into the browser tab's memory and process on your own CPU. Open DevTools → Network and observe zero outbound requests carrying file data while Crop PDF Pages runs.
- **No AI training on your file.** Loft does not train models. We could not train on a file we cannot see.
- **No content scanning.** No virus, copyright, or content-moderation pass against your file. The bytes are not accessible to us.
- **No server-side log of file contents, filenames, or EXIF metadata.** Cloudflare edge captures URL and truncated IP for abuse defense (standard CDN behaviour). Cloudflare Web Analytics records anonymous page hits, no cookies, no PII. Nothing about your file content reaches any log.
- **No retention.** Close the tab and the file leaves browser memory. No backups exist on our side because no copy ever existed on our side.
- **No account.** No email, no signup, no auth, no telemetry tied to you.
- **Offline-capable after first visit** (PWA). Once you've loaded a tool, it caches; later sessions work without internet. For high-sensitivity files, run the tool once online to warm the cache, then disconnect before processing.

Compare with upload-based services: each transmits your file to a processing server. Even over HTTPS, each has logs, retention windows, and subpoena exposure. Loft has none of these because the server architecture does not include your file.
