Need to Crop PDF Online without installing software? This free online PDF crop tool lets you visually draw crop zones directly on your PDF pages, preview changes in real-time, and export a perfectly trimmed PDF in seconds. Easy, quick, and operates directly in your browser
Visual Drag-to-Crop System – Draw crop areas directly on an interactive canvas. Every PDF page renders at high resolution so cropping stays pixel-precise.
Per-Page or All-Pages Mode – Toggle between “All Pages” and “Only This Page” using the switch control. Apply the same crop zone across every page or customize individual pages.
Live Crop Dimensions Label – A floating badge shows the exact crop size in points (pt) as you draw or resize, helping you hit exact dimensions for printing or layouts.
Sidebar Thumbnail Navigator – Scroll through all PDF pages as thumbnails. Pages with confirmed crops display a “Cropped” badge, and clicking any thumbnail jumps straight to that page.
Zoom & Pan Controls – Use plus/minus buttons, a fit-to-view option, or Ctrl+scroll to zoom. Pan freely by dragging with Alt held or using normal scroll, letting you crop small details effortlessly.
Instant Cancel & Redo – Each page has a dedicated delete button that removes the current crop area. Confirming a crop shows a green flash confirmation, and you can re-crop anytime before downloading.
A clean drop zone welcomes you to upload any PDF file. Once loaded, all pages appear as clickable thumbnails in a sidebar, while the existing page occupies a zoomable canvas display. You create a crop rectangle by clicking and dragging on the page, adjust its position with the center move handle, or refine the edges with the four corner grips. Confirming applies the crop immediately, and the download button exports your trimmed PDF with cropped pages maintained at original quality
Drop your PDF file onto the upload area or click anywhere in the box to browse files. The tool accepts standard PDF documents from any source.
Use the toggle switch to select "All Pages" for uniform cropping or "Only This Page" for selective trimming. The sidebar label updates to reflect your choice.
Click and drag anywhere on the canvas viewport to create a crop rectangle. Resize using corner handles or drag the center move icon to reposition the entire zone.
Click the green checkmark button to apply. The page thumbnail instantly shows a "Cropped" badge, and a green border flash confirms the action visually.
Hit the "Download" button. The tool processes all confirmed crop zones, sets precise PDF crop boxes, and delivers a neatly trimmed PDF file named after your original.
Toggle carefully: When”All Pages” is active, confirming a crop on any page applies to every page with existing crop data during download.
Use Fit zoom first: Click the “Fit” button to see the full page before drawing, then zoom in for precise edge adjustments.
Escape to cancel: Press the Escape key anytime to discard an active crop rectangle without confirming or deleting.
Check the dimension label: The floating pt size helps match exact print dimensions when cropping scanned documents or certificates.
Re-crop anytime: Confirmed crops are editable. Draw a new rectangle and confirm again – the old crop gets replaced instantly.
Your PDF never leaves your device. All cropping happens locally in the browser using JavaScript — no server uploads, keeping documents fully confidential.
A scrollable sidebar shows all pages with "Cropped" badges on modified ones. Click any thumbnail to jump instantly and verify or adjust individual crop zones.
A floating label shows exact crop size in points while you draw or resize, helping match print-ready dimensions without guesswork.
The canvas renders pages at double resolution, so every crop boundary snaps cleanly even on detailed layouts, blueprints, or tightly formatted documents.
Toggle between applying the same crop across all pages or customizing each page individually — no repetitive manual work required.
No signup forms, no watermarks on output, no page limits — upload, crop, and download your trimmed PDF immediately.
When you confirm a crop area on the canvas and click download, the tool calculates the exact coordinates relative to the original PDF page dimensions. It converts the visual crop rectangle into a PDF CropBox and MediaBox operation using the pdf-lib library. Each cropped page gets its visible area reset to only the selected zone, while the underlying content remains intact. The final PDF contains only the trimmed viewports, so file size decreases naturally when white margins or unwanted borders are removed. This crop pdf online approach preserves vector quality because it operates at the PDF specification level rather than rasterizing pages.
Yes. Switch the toggle to “Only This Page,” navigate to each page via thumbnails, and confirm separate crop zones individually.
It can. Removing large margins or whitespace trims visible page area, which may reduce output file size since less content area is rendered.
Yes. All features including unlimited pages, zoom, and download work without any payment or subscription.
They remain in the PDF data but become invisible in standard viewers since the crop box hides them. The trimmed view shows only your selected area.
Yes. Click the delete button (X icon near the crop area) to remove the crop from the current page, or draw a new rectangle and confirm to replace it.
Yes. You can switch between Medium, High, and Low at any point before clicking “Compress PDF.”
