Redact PDF online by drawing black boxes over sensitive regions, then flattening each page to an image so underlying text cannot be selected or copied. Ideal for sharing contracts and IDs without leaking SSNs — all in your browser, no upload.
PDFPages are rasterized with boxes burned in so text under redactions is not recoverable as a text layer.
Redaction runs locally. We never see the document you redact.

Share a PDF but black out names, account numbers, or faces before it leaves your machine — flattened redaction for screenshots and filings.
Redact PDF 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. Redaction runs locally. We never see the document you redact. 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.
Black-box regions and flatten pages so redacted content is unrecoverable. Before you run Redact PDF, 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.
Share a PDF but black out names, account numbers, or faces before it leaves your machine — flattened redaction for screenshots and filings. People reach for Redact PDF 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 protect-pdf, watermark-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.
Redact PDF 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.
Common questions
We flatten pages to images with black boxes — unlike simple black rectangles over live text.
Yes — switch pages, draw boxes on each, then download once.
Aim under ~50–100 MB depending on device RAM. Very large scans may stall older phones. (Redact PDF.)
Yes — download a new file and keep the source on disk as backup.
After the app shell and libraries are cached by your browser, many PDF tools keep working offline for that session.
