Guide & FAQ

Why Choose Dely PDF

Standard Presets or an Exact Custom Size

Resize to common paper sizes like A4, Letter, or Legal, or set an exact custom width and height in millimeters, centimeters, inches, or points.

Scale to Fit, or Keep Your Content As-Is

Let your content scale to fill the new page size automatically, or keep it at its original size and place it anywhere on the new canvas with the alignment control.

Resize Only the Pages You Choose

Apply the new size to every page, only odd or even ones, a specific range, or skip the first page, handy for leaving a cover page untouched.

Your Privacy Stays Protected

Pages are resized right in your browser. Nothing is sent to a server, so your documents never leave your device.

What Is This Tool For?

Standardize Scanned or Mixed-Size Pages

Merged a document with pages scanned at different sizes or orientations? Resize every page to one consistent standard like A4 so it reads cleanly.

Match Your Printer's Paper

Resize a PDF to Letter, A4, or Legal so it prints correctly on the paper you actually have loaded, without your printer scaling it unexpectedly.

Convert Between Paper Standards

Switch a document between A4 and Letter (or any other standard) when sharing across regions that use different default paper sizes.

Create Custom-Sized Documents

Set an exact width and height for non-standard formats like booklets, certificates, or labels, and even resize a JPG or PNG image straight onto that size.

How It Works

Add Your File

Add or drag a PDF (or an image) from your device. Everything runs in your browser, never sent to a server.

Choose a Size and Scaling

Pick a standard paper size or set a custom width and height, then decide whether content should scale to fit or stay original size with an alignment.

Save the Result

Download your resized PDF, ready to share or print.
