Your bank, your GP, your council — they all send PDFs now. The instructions are usually 'just sign and return', as if everyone learned this at school. If you didn't, you didn't. Here's the gentle version.
Opening and reading a PDF
A PDF is just a document — like a printed letter, but on screen. Click the file and it should open in your default viewer (often your web browser or a built-in app). If you can't read the text clearly, zoom in using the + button or the mouse wheel. PDFs always look the same wherever you open them, so don't worry about printing to check — what's on screen is what's on paper.
Signing without a printer
Most signing requests don't actually need printing. Use sign PDF in Flint, draw your signature with the mouse (or finger on a phone), drop it where it needs to go, and save. Send the saved file back as an attachment to the original email. No paper, no scanning, no posting. If you'd rather print and sign, that still works — just scan the signed paper back as a PDF before emailing.
Filling in forms
Some PDFs let you click into boxes and type. Some don't. If clicking does nothing, open the file in Flint's editor and you can type anywhere on the page. Click where you want the writing to appear, type your answer, click somewhere else to finish. Save before closing. This works for any form regardless of how it was made.
FAQ
Do I need to buy software?
No. Flint and many other tools work in your web browser for free. You don't need to install anything. If a service asks for payment for basic tasks like signing, look elsewhere first.
How do I know it's safe?
Use websites you've heard of or that came recommended. Don't enter passwords, bank details, or ID numbers into PDFs from senders you weren't expecting. When unsure, ask a family member to look first.
What if my file is too big to email?
Most email systems reject files over about 20 MB. Compress PDF makes them smaller. Or share via a cloud link your email provider offers (Gmail, Outlook both build this in).
PDFs are simpler than they pretend. Open one in Flint — the menus are plain, and there's no rush.
