Resize Page Size
Put every page of a PDF onto A4, Letter, Legal or a custom size — text stays sharp, because pages are scaled, not re-rendered.

PDFs arrive in whatever size their author used. Printers, forms and archives expect standard sizes — resizing bridges that gap without rebuilding the document.
Printing on standard paper
A US Letter document headed for an A4 printer, or vice versa, prints at the wrong scale until its pages match the paper.
Form and archive rules
Submissions and archives often mandate A4 or Letter. Resizing is the compliant step before filing.
Consistent documents
Merging files of mixed sizes leaves a ragged document. Normalising page size first keeps the merged result uniform.
How it works
Upload
Add the PDF. Its current page sizes are read locally.
Choose
Pick A4, Letter, Legal or a custom size, an orientation, and how pages fit the new box.
Download
Every page is re-placed at the new size in one PDF.
Key features
Standard presets
A4, US Letter and US Legal in one click, plus fully custom width and height.
Four fit modes
Fit, fill, stretch or centre — choose whether proportions, coverage or position wins.
Lossless text
Pages are embedded and scaled, not rasterised, so text stays selectable and sharp.
Orientation control
Force portrait or landscape independently of the chosen size.
Who uses Resize Page Size?
Preparing to print
Match a document to the paper size actually loaded in the printer.

Bring mixed-size sources to one size before or after merging.
Meeting a submission spec
Deliver a PDF at exactly the page size a form or archive requires.
Frequently asked questions
Is my PDF uploaded to resize its pages?
No. Pages are re-laid out locally in your browser with pdf-lib — nothing leaves your device.
Does resizing reduce quality?
Text and vector graphics scale losslessly. Only embedded raster images resample visually, as they must at a new size.
Can I resize only some pages?
This tool applies one size to all pages. For mixed sizes, split the file first, resize each part, and merge them back.
