About PDF crop
Trim margins or isolate a region on PDF pages without uploading anything. Use presets, fine-tune with sliders, or drag the live crop rectangle — then download a new file from your browser.
How it works
Dockzio updates each page's CropBox and MediaBox with pdf-lib. Viewers clip to the cropped region; page content outside the box is hidden, not rasterized.
Presets & manual
Start with Narrow, Normal, or Wide margins, then drag handles or edit left / right / top / bottom insets for a custom crop.
Selected or all pages
Apply the same crop to the pages you select, or crop every page in one step. Preview any page before you download.
Privacy first
Everything is processed locally in your browser. Your documents are never sent to a Dockzio server.
