Resize PDF Pages (A4 / Letter)
Scans and screenshot-PDFs often have a different size on every page, so printing crops content or leaves huge margins. Normalize every page to a standard paper size: content scaled proportionally and centered, landscape pages automatically on landscape paper. Everything runs locally in your browser.

FAQ
No. Scaling is proportional with the aspect ratio preserved; oversized content shrinks to fit with even margins.
Try it ↑Detected automatically: landscape content gets landscape paper (e.g. A4 rotated), portrait content gets portrait paper — no squashing.
Try it ↑Yes. Pages are embedded and scaled as vectors, so the text layer is preserved — nothing is rasterized.
Try it ↑No — resizing runs entirely 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.
