Why use Resize PDF?
A4 versus Letter mismatches break printing at the worst times. Resizing changes page dimensions or applies a scale factor so documents fit the paper you actually have. PDFBaba handles common paper targets and numeric scales used in pdfcpu workflows. No account is required, and uploads are deleted after roughly one hour. If you need multiple pages per sheet instead, look at N-up PDF; if you need to remove margins visually, Crop PDF may be the better first step.
Supported files & limits
One PDF; target paper size or scale factor. The default upload limit is 100MB per file; administrators can raise or lower this via server configuration. Fixes wrong page dimensions before printing or PDF/A conversion.
