What stays local, and what goes online.
What stays on your device
Your PDF file and the information you add to it stay in your browser while you edit. Just Fill PDF does not send your PDF, form entries, dates, checkmarks, initials, or signatures to its servers for editing.
Your PDF filename is not sent for analytics or license validation.
What goes online
Just Fill PDF sends limited product-usage events, such as opening the editor, adding a field, attempting a download, or clicking checkout. These events do not include your PDF or the information entered into it.
Payment is handled by Lemon Squeezy. License activation and validation send your license key and a browser license instance, not your PDF or form entries. Feedback is sent through Formspree only when you submit the feedback form.
Just Fill PDF does not currently use a separate error-reporting service.
Honest fit
When the $9 unlock makes sense
Just Fill PDF is for simple, private PDF form filling — not full PDF editing.
Pay once if
- The PDF has sensitive information
- You do not want to upload it to a cloud PDF editor
- You only need to add text, dates, checkmarks, initials, or a typed signature
- You want unlimited downloads and prints without a subscription
Don't pay if
- A free tool like Mac Preview already works for you
- OCR
- Merging, splitting, compressing, or converting PDFs
- Legal e-signature workflows with identity verification
- You need to edit original PDF text
Some free tools may already be enough. On Mac, Preview can handle many simple PDF tasks. If you need a full PDF suite, tools like PDF24, PDFgear, PDF-XChange, or LibreOffice Draw may be a better fit. Just Fill PDF is intentionally focused on private browser-based form filling.
