A PDF page can be any size its maker chose, and plenty are not a paper size at all: slides are 254 by 143 millimetres, exports from design tools come out at whatever the artboard was, and a document built in one country arrives in a letter-sized office that only stocks A4. Printers then shrink, stretch or clip the page in ways nobody asked for. This tool settles it in advance by redrawing every page onto the sheet you name, scaled to fit whole.
How to use Resize PDF Pages
- Add the PDF.
- Choose the paper size. A4 and Letter cover most needs; A3, A5, Legal and Tabloid are there too, and Custom size takes any width and height in millimetres.
- Choose the orientation. Follow each page keeps a landscape chart landscape inside a portrait report. Portrait or Landscape forces every page the same way.
- If the file is password protected, enter its password in the PDF password field.
- Select Resize Pages and download the result.
Fitted, not cropped
The whole of every page ends up on the new sheet, which is the part most resizing goes wrong.
- Scaled to fit: Each page is shrunk or grown until it fits inside the new sheet in both directions, so nothing at the edges is lost. A page that was already the right shape simply changes scale.
- Proportions are kept: Width and height are scaled by the same amount, so circles stay round and type keeps its proportions. Nothing is squashed to fill the sheet.
- Centred on the sheet: Whatever space is left over is shared evenly around the page rather than piling up on one side, which is what you want for something that will be printed and bound.
- Drawn, not rasterised: The page is redrawn at the new scale rather than photographed, so text stays selectable and vector lines stay sharp however far you zoom in.
Choosing a size and an orientation
- A4 or Letter: A4 is the standard almost everywhere outside North America; Letter is slightly wider and shorter and is the standard in the United States and Canada. Pick the one the printer at the other end stocks.
- Follow each page: The default orientation looks at each page and gives it a portrait or landscape sheet to match. That is right for a report with a few landscape tables in it.
- Forcing one orientation: Choosing Portrait or Landscape puts every page on the same sheet. A landscape page forced onto a portrait sheet is scaled down to fit, which is sometimes exactly what a binding requires.
- Custom sizes: Custom takes a width and height in millimetres, for photo paper, labels, book blocks and anything else that is not an office standard.
What resizing does and does not change
- Type gets smaller or larger: Scaling a page scales the words on it. Going from A3 down to A4 makes ten-point type read as about seven, which is worth checking before sending it to be printed.
- Margins grow: Fitting a squarer page onto a longer sheet leaves bands of white at the top and bottom. Crop PDF beforehand tightens the content so less space is wasted.
- Links and fields move: Interactive links and form fields are not rescaled with the page, so add them after resizing rather than before.
- File size barely changes: Nothing is re-encoded, so the result weighs about what the original did. Use Compress PDF if size is the actual problem.
When people use Resize PDF Pages
Slides for an A4 printer
A deck exported at slide proportions becomes a set of A4 landscape pages that print one to a sheet without the printer guessing.
A document from another country
A Letter-sized contract resized to A4 prints on European paper without the shrink-to-fit warning and the uneven margins that follow it.
Mixed pages made uniform
A merged bundle where every source used a different page size becomes one consistent document, which binds and reads far better.
Limitations to know
Resizing scales the content, so text on a page made much smaller becomes correspondingly harder to read; check a page at full size before printing a long document. Pages are fitted whole and centred, which means a page whose proportions differ from the new sheet gains white bands rather than being cropped. Links, form fields and annotations keep their original coordinates and will no longer line up with the content, so add them afterwards.
Resize PDF Pages: common questions
Will resizing cut anything off my pages?
No. Each page is scaled until it fits inside the new sheet in both directions, so the whole page is always there. If the proportions do not match, you get bands of white space rather than a crop. If you want a tighter result, crop the pages first and then resize.
What is the difference between resizing and cropping?
Cropping trims away the outside of a page and keeps what is left at its original scale. Resizing keeps the whole page and changes its scale to match a new sheet. Use Crop PDF to remove scanner edges or wide margins, and this tool to make pages a standard paper size.
Why are there white bands on my resized pages?
Because the original page is a different shape from the sheet you chose. Fitting a wide page onto a tall sheet leaves space above and below. That is the price of not cropping anything; cropping the pages first reduces it.
Does resizing make the file smaller?
Not meaningfully. The content is redrawn at a new scale but nothing is re-encoded, so images carry the same data whether they are displayed large or small. Compress PDF is the tool for reducing size.
Can I resize to a size that is not on the list?
Yes. Choose Custom size and type the width and height in millimetres. Anything from 10 mm to 2000 mm works, which covers labels and photo paper at one end and posters at the other.
