Resize PDF Pages to a New Paper Size
or drop files here
Move every page onto A4, Letter or a size you type, and decide whether the content shrinks to fit or keeps its exact size. Text stays vector, links follow their words, and the work happens in this tab.
Same pages, new paper.
Drop in the PDF
Choose the document that arrived in the wrong paper size. Files mixing several sizes and orientations are fine.
Choose the new sheet
Pick A4, Letter, Legal, A3, A5, Tabloid or your own width and height, then Scale to fit or Keep 100%. A small drawing shows page 1 on its new paper.
Save the resized file
Click Resize PDF and save it. Every chosen page now reports exactly the size you asked for.
Why a PDF ends up on the wrong paper.
Paper sizes split the world in two, and plenty of offices, printers and upload forms accept only one of them. These are the situations that bring people here.
A4 documents for US printers
An A4 contract sent to an office in the United States meets Letter trays. Converting it first means it prints at a size you chose, not one a printer driver guessed.
Letter files for everywhere else
Reports written in the US reach Europe, India and Australia on Letter pages. Resize them to A4 before filing with an agency or university that works in metric paper.
Portals that check page size
Court e-filing systems, grant portals and thesis offices sometimes refuse anything that is not A4 or Letter. Resize the file so the size check passes before you submit.
Mixed sizes in one bundle
Scanned receipts, a Letter invoice and an A4 statement make an untidy pack. Resize each file before merging them, or merge first and bring every page to one size in a single pass.
Larger prints from vector files
Plans, charts and posters built from vector drawing can go from A4 to A3 without any blur. Photos inside are enlarged too, with the same pixels spread over more paper.
Room for notes or binding
Put an A5 handout on A4 with Keep 100% and it gains 31 mm of blank paper at each side and 43.5 mm at the top and bottom, space for handwritten notes or a hole punch.
Scale to fit or Keep 100%: a worked example.
Take an A4 page, 595 × 842 points (210 × 297 mm), and put it on Letter, 612 × 792 points (215.9 × 279.4 mm). Letter is a little wider but noticeably shorter, and the two options handle that mismatch in opposite ways.
Scale to fit compares both directions. Across, the page could grow by 612 ÷ 595 = 1.03; down, it has to shrink by 792 ÷ 842 = 0.94. The smaller number wins, so the whole page is drawn at 94%. It fills the height exactly, ends up 560 points wide and sits centred with 26 points (about 9.2 mm, or 0.36 in) of white at the left and right. Nothing is lost, and 11 pt body text prints at roughly 10.3 pt.
Keep 100% centres the A4 content on the Letter sheet untouched. Across, that leaves about 8 points (3 mm) of new white space on each side. Down, the page is 50 points taller than the sheet, so roughly 25 points (8.8 mm) at the top and the same at the bottom fall outside the page and are neither shown nor printed. That is harmless when those bands are blank margin, and a problem when a header or page number sits near the edge.
In both cases nothing is redrawn. The page's existing drawing instructions are wrapped in one scale-and-shift instruction, so fonts stay fonts, lines stay lines and photos keep every pixel, and the file barely grows. Links, form fields and comments receive the same scale and shift, which keeps each link sitting on the words it belongs to.
Scale to fit, common conversions
| Conversion | Scale | White space added |
|---|---|---|
| A4 → Letter | 94.1% | 9.2 mm left and right |
| Letter → A4 | 97.3% | 12.6 mm top and bottom |
| Legal → Letter | 78.6% | 23.1 mm left and right |
| Letter → Legal | 100% | 38.1 mm top and bottom |
| A4 → A5 | 70.5% | Almost none |
| A4 → A3 | 141.4% | None |
Portrait pages with Match each page. The A sizes all share one shape, which is why A4 to A5 or A3 needs essentially no extra white space.
