Add Blank Page is built for private, in-browser work. Upload-based PDF sites often store temporary copies on someone else’s disk; SortMyFile’s default is the opposite — processing stays on your device for this utility. Blank pages are created on-device. Your PDF contents stay in the tab. If a step needs a one-time language pack or WASM library from a CDN, that is asset delivery — not your document contents being sent to SortMyFile for server-side processing. Close the tab when you are done if you want memory cleared.
Insert blank pages at the end of a PDF. Before you run Add Blank Page, keep an original copy of every source file. Spot-check the download on the same device you will use for the portal or email. Large scans and phone photos are limited by browser RAM — if a run stalls, shrink the input first or split the job. SortMyFile browser tools stay free forever with no daily caps.
Add a signature sheet after a contract, or pad a booklet so chapters start on a right-hand page before print. People reach for Add Blank Page when a form, HR desk, or messaging app rejects the current file shape, size, or format and installing desktop software is overkill. Pair it with delete-blank-pages, merge-pdf, compress-pdf when you need a short pipeline (for example compress then OCR, or HEIC to JPG then JPG to PDF). Results are not a substitute for official portal rules — always re-read the receiving site’s instructions before a deadline.
Add Blank Page trades convenience for honesty about browser limits. Extremely large files, corrupted inputs, or DRM-protected media can fail. Password-protected PDFs need a password you already know — SortMyFile does not crack encryption. Free use does not require an account; Pro (when checkout ships) is planned to raise limits and reduce ads. Until then, the free tier is enough for most one-off private jobs.
