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.

FAQ

Quick answers to common questions.

Upload a PDF, choose a margin preset or drag a custom crop rectangle on the live preview, select pages, then apply. Dockzio updates each page's CropBox and MediaBox in your browser and downloads the cropped file.
