PaperKitResize a PDF to US Letter (8.5 × 11 in) without uploading it
Convert any PDF to US Letter in your browser: every page becomes 612 × 792 points, content scaled to fit. Free, no upload, made for A4 files printed in the US.
Quick answer. US Letter is 8.5 × 11 inches, which is 612 × 792 PDF points or 216 × 279 mm. To convert a PDF to Letter:
- Open Resize PDF with Letter and Fit to page preselected, drop the file, click Resize PDF
- Each page is scaled proportionally and centred on a Letter sheet, so nothing is clipped
- An A4 page shrinks by about 6% and gains a small margin on the left and right
- The file never leaves your browser and downloads as paperkit-resized.pdf
A4 to Letter: what changes on the page
A4 is 595 × 842 points, Letter is 612 × 792. Letter is 17 points wider and 50 points shorter, so an A4 page scaled to fit Letter is reduced to about 94% and sits with roughly 17 points of extra white space on each side. Text stays sharp because the page is scaled as vector content, not rasterised.
When to keep the content size instead
Choose Keep content size if the document has links, bookmarks, or form fields you need to preserve. In that mode nothing is scaled, so the taller A4 page is clipped at the top; check the preview before downloading.
- Fit to page: scales and centres, drops links and form fields
- Keep content size: preserves links and fields, clips the top of A4 pages
- Mixed sizes in one file: every page becomes Letter either way
Printing a European document in the United States or Canada
North American printers and copy shops default to Letter paper. An A4 PDF sent as is either loses its last lines or is shrunk by the driver. Resizing to Letter first gives a predictable print and avoids the fit-to-page guesswork in the print dialog.
Submitting to a venue that requires Letter
US journals, IEEE conferences, and many court and government portals require Letter. Resize the exported PDF, then run Remove PDF Metadata for anonymous review and Compress PDF if the portal has a size limit. The IEEE paper margins page lists the Letter template margins if the layout itself must change.
Other sizes
The same tool resizes to A4, Legal (612x1008), A5, Square, or any custom width x height in points; 72 points make an inch, so a 5 × 7 inch card is 360x504.
