Crop & Trim PDF Margins

Crop margins, exactly right — top, bottom, left, and right, in millimeters. Crop & Trim PDF Margins is a PDF app built around exactly one thing: cropping margins. When a scanned document has margins that are too wide, or leftover white space from a print layout, this fixes it right there, right now.

Pricing (In-App Purchase) The app is free to download, and cropping margins and previewing the result are free for everyone. Saving and sharing your processed PDF requires a one-time unlock (¥400, non-consumable). This is not a subscription — pay once, with no recurring charges.

Three modes

• All pages: apply the same margins (top/bottom/left/right, in mm) to every page
• Odd/Even: set different margins for odd and even pages — handy for double-sided scans
• Page range: specify target pages using a format like "1-3,5,7-9"

Simple by design Open the app, pick a PDF, enter your margins. No manual needed. We stripped away the extras and focused on one thing: cropping margins.

Text and links stay intact OCR text, hyperlinks, and bookmarks are all preserved. The app only changes each page's visible area (the CropBox) — it does not regenerate the page content itself. It also handles rotated pages (e.g. scanned PDFs) correctly, cropping margins according to the orientation you actually see on screen.

Built to trust

• Fully offline: your files never leave your device. Your privacy stays yours
• No ads, no account required
• Unlocking save and share is a one-time purchase (¥400). No subscription

Great for when you want to:

• Trim down oversized margins on a scanned document to make it easier to read
• Fix mismatched margins on odd/even pages from a double-sided scan
• Crop margins on specific pages to make a document look consistent
