One editor for filling, creating, signing, and annotating a PDF
The tool above is the same free editor behind every fill, sign, create, and annotate page on fillable.ca — it opens whatever PDF you drop into it and works out what you need. If the file already has interactive form fields, they're detected automatically and listed in a panel on the right, so you can tab through them or use Auto-fill from my profile instead of clicking around the page. If it's a flat or scanned document, pick the text, checkmark, date, or signature tool from the toolbar and place your entries directly on the page, exactly where they belong.
Everything happens in your browser using JavaScript: the PDF is parsed, your edits are drawn onto it, and the finished file is rebuilt locally before you download it. Nothing is uploaded to a server for filling, signing, or annotating, and no account is required to get your document back. When you're done, click Download to save a flattened copy — your text, checkmarks, and signature become a permanent part of the page rather than editable fields someone else could change.

Frequently asked questions
Do I need an account to use the editor?
No. Drop in a PDF and start working — there's no sign-up required to fill, sign, annotate, or download.
Does my PDF get uploaded anywhere?
No. The editor above runs in your browser. Your file is read, edited, and rebuilt on your device, and it is not sent to a server for these operations.
What if my PDF already has form fields?
The editor detects them automatically and shows a Form fields panel on the right, so you can type straight into the real fields instead of placing text manually.
Can I fill a scanned or flat PDF that has no fields?
Yes. Pick the text, checkmark, date, or signature tool from the toolbar and click anywhere on the page to place it.
Is the finished PDF locked once I download it?
Downloading flattens what you've added into the page, so your entries become part of the document rather than remaining separately editable fields.
