What is Resize PDF and how does it work?

Resize PDF is a free online tool from HuntPDF. Resize PDF pages to A4, Letter, Legal, A3 or A5. You upload a file, the work happens on our servers, and you download the result. There is nothing to install and no account to create.

How do I use Resize PDF online?

Upload your file using the box above — drag it in, browse for it, or bring it in from your cloud storage. A preview appears so you can check you've picked the right file. Run Resize PDF, then download the result. You can rename it before you save it.

Is my file secure when I use Resize PDF?

Yes. The file you send to Resize PDF travels over an encrypted HTTPS connection and is processed automatically on our servers. It is never made public, never shared with anyone, and nobody reads it.

Does HuntPDF store my files after Resize PDF has run?

No. Your upload is deleted the moment Resize PDF finishes with it, and the file it produces is removed as soon as you have downloaded it, or when you upload another file, or when you close the page. Nothing is kept, and nothing is used to train anything.

Will the original quality and formatting be maintained?

Yes. Resize PDF is built to leave your content exactly as it is — only the change you asked for is applied. Nothing else about the file is altered or re-compressed.

Can I use Resize PDF on mobile?

Yes. Resize PDF works in any modern browser on phones and tablets — iPhone, iPad or Android — with nothing to install. You can upload straight from your device or from your cloud storage.

Can I rename my file before downloading it from Resize PDF?

Yes. The file Resize PDF gives you back keeps the name of the file you uploaded by default. If you'd rather call it something else, edit the name in the field next to the download button before you save it.

Do I need to install any software to use Resize PDF?

No. There is nothing to download, install or sign up for — Resize PDF is used from your browser and does the work on our servers, so it behaves the same on Windows, macOS, Linux, Android and iOS.

How long does Resize PDF take?

Most files are finished in a few seconds. A large or page-heavy file takes a little longer, because Resize PDF runs on our servers rather than on your device — but you won't be waiting around. You can upload files up to 250MB.

Is Resize PDF free to use?

Yes. Resize PDF is free, with no signup, no watermark on the result and no daily limit for normal use.

Does Resize PDF crop anything?

No. Pages are scaled to fit and centred on the new sheet, so the whole page stays visible. To trim margins away, use Crop PDF instead.

Which paper sizes can I resize a PDF to?

A4, Letter, Legal, A3 and A5. Your file's current size is marked Now.

Can I turn portrait pages into landscape?

Set Orientation to Landscape and every page is laid out on a landscape sheet. Leave it on Follow each page if the document mixes both and you want to keep that mix.

Will text look distorted after resizing?

No. Content is scaled evenly in both directions, so letters keep their shape. Any difference in proportions shows up as extra white space, not as stretched text.

Why does my Letter-size PDF print badly on A4 paper?

Letter is about 216 mm wide and 279 mm tall, while A4 is 210 by 297. Resizing to A4 first gives the printer a page that matches the paper.

Can I use Resize PDF on a file with pages of different sizes?

Yes. Every page is fitted to the size you pick, which is the easy way to make a mixed bundle uniform.

Resize PDF changes the page size of a PDF, for example from US Letter to A4, and scales each page's content to fit the new sheet. It fixes documents that print with clipped margins.

How to use Resize PDF

Add the PDF by dropping it on the page or choosing it from your device, Google Drive, Dropbox or OneDrive (up to 260 MB). The tool shows the current page size first. Pick the new size: A4 (210 × 297 mm), Letter (8.5 × 11 in), Legal (8.5 × 14 in), A3 or A5. Then set the orientation. Follow each page keeps each page's own orientation, while Portrait or Landscape forces every page one way. Press Change to A4 (or your chosen size) and download the new file.

When Resize PDF is the right fix

Paper sizes differ by region. A contract drafted in the US on Letter paper can print with clipped footers on an A4 printer in Dubai or London. Resizing to the local size avoids that. It also helps when a scanned A5 receipt sits among A4 reports and you want every page to match.

What happens to the content

Each page is scaled to fit the new size and centred, so nothing is cut off. When the proportions of the old and new sizes differ (Letter is a little wider and shorter than A4), you get a thin margin on two sides rather than stretched text. Going from A4 to A5 shrinks small print, so check it is still readable.
