If you are tired of typing a password every time you open a PDF, such as a bank statement, a utility bill or an internal company file, and you know that password, this tool exports a copy that opens without one. Drop the PDF onto the upload area; if it has an open password, your browser asks for it. A wrong password lets you try again, and Cancel stops. Once the file opens, the panel shows the page count and encryption status, and Remove Password & Export PDF downloads alpa_unlocked.pdf.
Some PDFs open without a password but block printing, copying text or editing. Those limits come from a permissions (owner) password. Such files load directly without asking for anything, and the exported copy carries no permission settings, so you can print it normally. In that case the status reads Not Encrypted, because it only reports whether an open password is required.
Under the hood, every page is rendered to a high-quality JPEG at roughly 130 DPI and placed into a brand-new PDF with the original page size, which is why the result has no password or restrictions at all. The trade-off is that the new file is image-based: text cannot be selected, copied or searched, hyperlinks, bookmarks and form fields are not kept, and the file may be larger than the original. Keep the original if you need searchable text, or run OCR on the new copy.
This is not a password cracker. Without the open password the content cannot be read, and the tool never tries to guess it. It also does not add passwords to PDFs. Everything runs in your browser, so neither the PDF nor the password is uploaded. Only use it on documents that are yours or that you are authorized to use.
