Good to know
Can I open a password-protected PDF?
Use Unlock PDF with a password you know before using the other tools. Only modify documents you own or have permission to use.
Will every PDF feature be preserved?
Review results before sharing. Forms, bookmarks, accessibility tags, attachments and existing digital signatures may not survive document transformations. Image-based compression and image exports flatten the page’s appearance.
What if processing fails?
Your browser’s available memory affects the documents it can process. Try fewer pages or a smaller file if a document cannot open or export. Keep your original file as a backup.
