자주 묻는 질문
Is PDF 잠금 해제 free?
Yes. PDF 잠금 해제 is completely free with no sign-up, no watermark and no daily limit. There is no paid tier — every tool on iAdorePDF is free to use as often as you like.
Is PDF 잠금 해제 safe and private?
Yes. PDF 잠금 해제 runs entirely inside your browser, so your file is never uploaded to any server. Nothing leaves your device, which makes it safe for confidential documents.
Do I need to install any software?
No. PDF 잠금 해제 works in any modern browser — Chrome, Safari, Firefox or Edge. There is nothing to download and no account to create.
Does PDF 잠금 해제 work on a phone?
Yes. PDF 잠금 해제 is built mobile-first and works on iPhone and Android exactly as it does on a computer, straight from the browser.
Which kind of PDF protection can be removed?
This removes owner restrictions that block printing, copying or editing on files you are allowed to use. It cannot break a password you do not know, and you should only unlock documents you own or have permission to modify.
How do I use PDF 잠금 해제?
Open the page, drop your file into the upload box (or tap Select file), choose your options, then press the start button. Your result downloads straight to your device.
Is there a file size limit?
There is no server limit because the work happens on your own device. The practical ceiling is your device memory; files up to about 100 MB are comfortable on most phones and much larger on a computer.
