Extract Region (Lossless)
Draw a box on a PDF page and extract just that region — vector text and lines preserved, outside images removed.
Cut a Region Out of a PDF Without Losing Quality
More than a crop
A normal PDF crop only changes what viewers display — the content outside the box is still in the file, still selectable, still leaking into text extraction. This tool goes further: it copies the pages you pick into a new document, shrinks each page's MediaBox and CropBox to the region you drew, wraps the content in a clip path, and deletes images painted entirely outside the box.
The result is a genuinely smaller document, not a masked one. And because nothing is rasterized, the kept region stays a real PDF — text selectable and searchable, vector lines sharp at any zoom, fonts embedded as before.
How the purge works
With 'Remove outside content' on, the tool parses each page's content stream, tracks the graphics-state transform through q/Q/cm operators, and computes where every image actually lands. An image whose bounding box lies entirely outside your region is deleted outright; anything touching the region is kept and clipped to the boundary.
Text and vector operators are never deleted — they're clipped instead. That's the honest trade-off: a paragraph that straddles the boundary keeps its outside half in the file (invisible, but still selectable), while a photo fully outside is gone for good. For most documents the purge removes the bulk of the outside weight without touching a single glyph.
What you can do
Region extraction that produces a real PDF.
Draw the region
Drag a box on the live page preview — move it, resize it from the corners.
Pick the pages
Apply the region to all pages, a range like 1-5, odd/even, or a comma list.
Text stays text
No rasterization — the output is selectable, searchable, and screen-reader friendly.
Private by design
Everything runs in your browser. The file never leaves your device.
When to use this vs. Crop PDF
Use Crop PDF when you want to change what a page looks like — trim scanner borders, tighten margins — while keeping the whole document. Use this tool when you want a new document containing only the region: one chart out of a report, one column out of a two-column scan, one panel out of a drawing. The output is a fresh PDF with just those pages, each sized to the box.
