Open pdfedit.com/crop-pdf in any browser, drop your PDF onto the page. The crop modal opens automatically. Click Auto-detect content margins or set them with the four sliders. Click Apply, then Save. No account, no upload, no Adobe Pro.

How do I crop a PDF for free?

Use this tool — 100% free, no signup, no daily quota. Drop the PDF, set margins, apply, save. The crop runs in your browser using pdf-lib.

Yes. PDFs have a CropBox property that controls the visible region of each page — every PDF reader respects it. Cropping a PDF means setting that CropBox to a smaller rectangle. We do that in your browser without modifying the underlying content stream, so the original layout can be restored.

How do I crop a PDF on Mac?

Two options: (1) macOS Preview — File → Open the PDF → drag a selection rectangle around what you want to keep → Tools → Crop. Works offline, no install. (2) This tool — drop the PDF here, the crop modal opens, set margins or auto-detect, apply. Useful when Preview isn't available or when you need batch-style margin control.

How do I crop a PDF in Adobe?

In Adobe Acrobat Pro ($19.99/month): Edit PDF → Crop Pages → drag a rectangle on the page → set margins for all pages → OK. Adobe also offers Remove White Margins which auto-detects content. We do the same auto-detect, free, in your browser, no install.

Is this PDF crop tool free?

Yes. 100% free forever — no trial, no premium tier, no per-file charge, no daily quota.

No. The crop runs entirely in your browser via pdf-lib. Your PDF never leaves your device.

Will the cropped content be permanently deleted?

No — this is a soft crop (CropBox). The original page bounds are preserved in the file's MediaBox; the CropBox just defines the visible region. Reopening the PDF in any editor and resetting the CropBox restores the trimmed area. This is the same behaviour Adobe Acrobat's Crop tool produces.

Can I auto-detect content margins?

Yes — click Auto-detect content margins in the modal. We render page 1, scan for the bounding box of non-white pixels, and set margins to crop tight to the content with a small padding. Most documents have consistent margins across pages so page 1 is a reliable sample. Best for scanned documents, slides exported as PDF, and any doc with surrounding whitespace.

Can I crop one page or all pages?

Both. The modal has a scope selector — Apply to all pages (default) or Current page only. The current-page mode is useful for fixing odd one-off pages without altering the rest of the document.

Will the cropped PDF lose any quality?

No. Cropping doesn't re-encode any content — it just sets a smaller visible region. Text stays text, images stay images, vectors stay vectors at full fidelity. The output file size is essentially identical to the input.

What is a CropBox in a PDF?

PDFs have several boxes per page — MediaBox (full physical extent), CropBox (visible region in viewers), BleedBox (print bleed), TrimBox (final trim line), ArtBox (meaningful content). Setting the CropBox is what 'cropping' actually means in PDF terms. Adobe, Preview, and our tool all set CropBox.

Does it work on mobile?

Yes. iPhone Safari, iPad, Android Chrome — any modern mobile browser.

What's the best way to crop a PDF?

For privacy-first cropping with auto-detect and no upload, we believe pdfedit.com is the best free option. On Mac, Preview's built-in crop is a solid offline alternative. For desktop / batch automation, Adobe Acrobat Pro is the gold standard but costs $19.99/month.
