Remove PDF Password

Use a password you already know to make an unprotected local raster copy of a PDF.

Privacy: your files never leave your device. All processing happens locally in your browser.

How to use

  1. 1.Choose the password-protected PDF you are authorized to open.
  2. 2.Enter its current password; the password is used only in this browser tab.
  3. 3.Create the unprotected raster copy, review it, and download it only when flattened pages are acceptable.

About Remove PDF Password

Remove PDF Password makes a new unprotected raster copy when you already know the current password. The file and password stay in the browser. PDF.js uses the supplied password to open the local document, renders the visible pages, and pdf-lib writes those rendered pages into a fresh PDF without carrying forward the encrypted source structure.

This is not a lossless decrypt-and-save tool. Each page is rebuilt from a browser-rendered image at 1.5 scale. The output does not preserve selectable text, links, form controls, annotations, signatures, layers, vector objects, tags, metadata, original image encodings, or the original encryption configuration. It should be treated as a visual copy, not a replacement for a legal, archival, accessible, editable, or signed source document.

The page size is kept, but rendered image quality and output file size can differ from the original. An incorrect password, malformed PDF, oversized page, or any failed verification produces no download. The completed raster copy is reopened without a password and its page count is checked before the download link appears.

For safety, this version accepts up to 25 MB, 40 pages, 12,000 pixels on either rendered page edge, 40 megapixels per page, and 100 megapixels across the job. Use it only for a document you are authorized to open, keep the encrypted original, and inspect the copy before sharing it. Use a trusted PDF editor when you need a lossless password change or removal that preserves document semantics.

Methodology & sources

Validate and open a single bounded local PDF through PDF.js with the user-supplied password, preflight every 1.5-scale page against page, dimension, per-page, and total-pixel budgets, render each page on an opaque canvas, JPEG-encode it locally, place it at the original page dimensions in a new pdf-lib document, reopen the unencrypted result with pdf-lib and PDF.js without a password, verify page count, and release all temporary canvases, worker tasks, and download URLs.

Frequently asked questions

Do I need the current PDF password?
Yes. This tool only opens a local PDF with a password you provide; it does not bypass or guess passwords.
Will text, links, forms, and signatures remain editable?
No. The output is a raster copy of visible pages, so those original document features are not preserved.
Is my password uploaded?
No. The source file, password, rendering, and PDF assembly stay in the current browser tab.
Why can the output size change?
Rendered page images use a different encoding from the original encrypted PDF, so the output may be larger or smaller.
