Resize PDF pages to A4, Letter — or any scale
Mixed page sizes become one clean, uniform document.

Scans, exports and merged files often end up with mismatched page sizes. Bindery rebuilds every page at your target size — A4, Letter or Legal, portrait or landscape — with the content scaled proportionally and centered. Or scale the whole document by a percentage instead.
Text stays real text and vector graphics stay sharp — pages are re-laid-out, not rasterized. Bindery runs entirely in your browser — your file is never uploaded, so there is nothing to delete from a server afterwards.

- Pick a page size or a scale percentage
- Download the uniform document
Why page sizes drift
A document assembled from several sources rarely has one page size. Scans come out at the scanner’s sheet size, a Word export uses the author’s locale — A4 in most of the world, Letter in North America — and a slide deck is a wide 16:9 page. Printers, e-filing systems and print shops often insist on one size for the whole file, and a viewer that shows pages “fit to width” hides the difference until someone prints it.
Resize rebuilds every page at the target size — A4, Letter or Legal, portrait or landscape — placing the original content scaled proportionally and centred. Nothing is cropped: a wide page on portrait A4 simply gets margins above and below. Choose a percentage instead to scale the whole document, which is handy for shrinking oversized drawings or enlarging small forms.
Vectors stay vectors
The page is embedded as a drawing and scaled, not rendered to pixels. Text remains selectable and searchable, lines stay crisp at any zoom, and images keep the pixels they had. That also means Resize cannot make a low-resolution scan sharper; if the scan is the problem, Clean scanned PDF improves contrast and skew, and OCR adds the text layer.
Because pages are re-laid-out into a new document, form fields and bookmarks are not carried over. Flatten a filled form first; add bookmarks afterwards with a merge if you need them.
Resizing in the browser versus uploading
| Resize pages | Bindery | Upload-based tools |
|---|---|---|
| Where the file is processed | In your browser tab, on your device | Uploaded to the service’s servers |
| Output quality | Vector content scaled; text stays text | Varies — some tools rasterise pages |
| Sizes | A4, Letter, Legal, portrait or landscape, or any percentage | A fixed list |
| What exists afterwards | The original and the new file, both on your device | A server copy until the retention window ends |
| Works offline | Yes, once the app has loaded | No |

Questions people ask
Does resizing blur the content?
No. The page content is embedded and scaled as vectors and original images — nothing is re-rendered to pixels, so text stays selectable and sharp.
What happens to pages with different orientations?
Every page is fitted proportionally onto the target size and centered, so nothing is cropped — a wide page on portrait A4 simply gets margins above and below.
Is the file uploaded to resize it?
No. The rebuild happens entirely in your browser, and the original file stays untouched on your device.
Can I resize only some pages?
Resize applies one target to the whole document so the output is uniform. To change a few pages, extract them, resize the extract, then merge it back in the right place with Mix pages.
What is the difference between A4 and Letter?
A4 is 210 × 297 mm; US Letter is 8.5 × 11 in (216 × 279 mm). Letter is slightly wider and shorter. Content scaled between them loses a few percent of size, which is invisible for most documents but matters for forms that must print at exact scale.
Will scaling to a percentage change the page size?
Yes. A percentage scales both the page and its content, so 50% halves the page dimensions. Use a named size when the sheet must match a standard.
