Everything Resize PDF can do

Put every page of a document onto a standard sheet: A4, A3, A5, Letter or Legal.

Page size

A4, A3, A5, Letter or Legal
Portrait or landscape, chosen separately from the size
Every page in the document set to the same sheet

How the content fits

Keep proportions: content scaled to fit and centred on the sheet
Stretch to fill: content drawn right across the new sheet
Keeping proportions leaves the spare space evenly on all four sides

What survives the change

Text stays selectable text at its new size
Images and vector drawings scale along with the page
Pages stay in their original order
Your original file is left untouched

Before and after

The whole document shown on screen before you resize
The result screen names the size and orientation you chose

Several PDFs resized at once, all to the same size, in one ZIP
Done in your browser, so your file is never uploaded

How it works

Resize PDF in three steps

Add your PDF

Drag your PDF onto the panel, or click it to pick one from your device. You can add several PDFs at once: they all get the same settings and download together in one ZIP. Everything happens in your browser, so your files stay on your device and are never uploaded.

Pick the new page size

Choose the target size. Keep proportions, the default, scales the content to fit without stretching or cropping it; Stretch to fill covers the whole page instead.

Resize and download

Every page is rewritten at the new size, ready to print on the paper you actually have.

Frequently asked questions about Resize PDF

How do I change a PDF from Letter to A4?

Open it here, choose A4 and Portrait, and leave "Keep proportions" selected. Each Letter page is scaled down slightly to fit the A4 sheet and centred on it, so a thin margin appears at the top and bottom instead of anything being cut off.

Which page sizes are supported?

A4, A3, A5, Letter and Legal, in portrait or landscape.

Can I change a PDF from Oficio or Legal size to Letter or A4?

Yes. Open the file, choose Letter or A4, and keep Keep proportions selected. Every page, whatever size it is now, is scaled to fit the new sheet and centred, so a longer Oficio or Legal page comes out complete, a little smaller, with a margin on the left and right. Oficio itself is not offered as a target size.

Will my content get stretched?

Not unless you choose to. With "Keep proportions", the default, the content is scaled evenly to fit the new page and centred, so nothing is distorted or cropped. "Stretch to fill" scales the width and the height separately so the content covers the whole page, which changes its proportions when the two page shapes differ.

Does resizing a PDF make the file smaller?

No. Resize changes the paper size the pages are set on, not how many megabytes the file takes. To reduce the file size, use Compress PDF.

Can I set a custom page size?

No. The choice is A4, A3, A5, Letter or Legal, in portrait or landscape, and every page in the document is set to the size you pick. There is no per-page setting.

Will resizing make the text blurry?

No. The page content is scaled as it is rather than redrawn as a picture, so text and line art stay sharp and selectable, and images are not re-compressed.

Can I do many files at once?

Yes. Add up to 10 PDFs at once, or up to 50 when you are signed in (an account is free). Every page of every file is set to the size you pick, and you download them together in one ZIP. The whole set counts as one task. If one file cannot be resized, for example because it has a password, the others still finish, and the result screen says which file it was and why.

What happens to my file?

It stays on your device. Your browser does the work and makes the download, so the file is never uploaded. We keep a record that the tool was used, but not the file name or what is in the file.

Is it free?

Yes. Every tool works without paying and without an account. Files can be up to 200 pages and 50 MB, and a run that fails costs you nothing. Pro removes the limits.

Do I need to create an account?

No. All tools work without signing in. An account raises your allowance and lets you see what you have processed.
