Trim excess margins from every page — remove scan borders, white space, or unwanted edges by setting a percentage to cut from each side. Runs fully in your browser.
Scanned documents often carry excess white space or a dark border from the scanner bed. Cropping removes that margin so the page prints and displays cleanly. This tool adjusts the PDF page's crop box on every page by a percentage you set for each side.
Technically, a PDF page has both a full "media box" and an optional "crop box" that tells viewers what area to actually display. This tool calculates and sets a new crop box based on your percentages — content is not deleted, just the visible boundary is trimmed. All done client-side, no upload.
Choose your PDF, set how much to trim from the top, bottom, left and right as a percentage, and click Crop. Every page is cropped the same way and the file downloads instantly.
Percentage cropping scales correctly regardless of the original page size (A4, Letter, or custom), so the same settings work consistently across documents.
Preview the percentage carefully — cropping too aggressively can clip text or images near the edges. Start with small values like 5-8% and increase if needed.
Cropping changes the visible page area, not the underlying content resolution, so file size stays roughly the same.
No. Cropping happens entirely in your browser using the PDF's crop box property — no server involved.
