Convert PDF to A4 (Standardize Page Size)
PDFs built from scans and screenshots come in wildly different page sizes, so printing clips content or shrinks it into a corner. The target size is preset to A4 here: each page is scaled proportionally into an A4 sheet and centered, landscape pages automatically use landscape A4, and text stays vector and selectable. Everything runs locally in your browser.

Try it ↑No. Any change to a signed PDF (merging, compressing, watermarking…) invalidates the existing digital signature — that is the tamper-proof design of PDF signatures, not a limit of this site. Process first, then sign.
Try it ↑Yes — and you can verify it: the tool runs on open-source in-browser engines (pdf-lib, pdf.js, Tesseract OCR…) on your own device. Open DevTools → Network while processing and you will see no file upload requests.

Resize PDF Pages to A4
Scans and screenshot-PDFs often have a different size on every page, so printing crops content or leaves huge margins
