Take the password off a file you can open.
Self-check
Nothing unlocked yet
Type the password the file opens with, and the tool writes a copy that has none. Before offering it, it re-opens that copy from its own bytes with no password — which must succeed — and checks that every page and its content came across.
No. This tool removes a password you can already open the file with; it does not find, guess or reset one. Nothing you type reaches Steady PDF and no copy of your file exists here, so there is no account or support path that could recover it either. If the password is genuinely lost, the person or system that created the document is the only route back.
Gone. The pages are copied into a document that was never encrypted, so the finished file has no encryption dictionary to hide anything behind. The tool then opens that finished file from its own bytes with no password at all — the way anybody you send it to would — and will not offer it for download unless that succeeds.
No, and the tool says so rather than quietly trying. A file like that carries owner-password restrictions rather than a password to open it. Removing those is taking off a restriction whoever made the document chose to set, which is a different thing from opening a file you are locked out of, and this tool does not do it.
No. This is a static page with no endpoint to upload to: the decryption, the page copy and the checks all run in this browser tab. Open your browser's network panel while you use it, or disconnect from the internet once the page has loaded and watch it keep working.
Because the pages are copied into a new document, and a PDF's fillable fields are registered on the document rather than on the page. The field's appearance and any value already in it come across as page content; the field itself does not. The tool reports when the document you chose had form fields, so this is never a surprise found later.
Yes — that is the pair these two tools make. Remove the old password here, then use the protection tool on the unlocked copy to encrypt it with the password you want. Each step checks its own result before handing you a file.
