About PDF resize
Change PDF pages to Letter, A4, and other standard sizes — or a custom width and height — without uploading anything. Preview the new page boundary, then download a resized file from your browser.
How it works
Dockzio embeds each selected page onto a new page at your target size with pdf-lib. Fit keeps aspect ratio and centers; Stretch fills the page; Center keeps the original size.
Supported paper sizes
Letter, Legal, Tabloid, A3, A4, A5, Executive, and B5 — plus custom dimensions in inches or millimeters. Switch portrait or landscape for presets.
When to resize
Use resize when a document must match a printer tray, submission template, or mixed-size export. Prefer Crop when you only need to trim margins without changing the paper size.
Privacy first
Everything is processed locally in your browser. Your documents are never sent to a Dockzio server.
