How to deal with PDFs when you only have a phone

Full PDF kit, screen the size of your hand.

Your laptop is at home, you're at the airport, the recruiter wants a signed contract by 3pm. Phones can do almost everything PDFs need now — the trick is knowing where to look.

Signing on the move

Open the PDF in Flint's sign-pdf via your phone browser. Draw your signature with a finger — it usually looks better than mouse-drawn. Drop it where it needs to go, save, share. Send via email or messaging app directly from your phone. Two minutes start to finish. Works on iPhone and Android equally well.

Editing and filling forms

Flint's editor works on touchscreens — tap to add text, drag to position. Mobile keyboards make typing slower than desktop, so this is fine for short fills (name, date, signature) but tiring for long forms. For multi-page form-filling, find a tablet or laptop. For one box on one page, phone is faster than getting a laptop out.

Compressing and sending

Phone photos of documents are massive. Compress PDF before sending — typical phone-scanned receipts shrink 80%. For multiple receipts, scan all of them with your phone's scanner app, then merge into one PDF and compress. The whole expense report from a coffee shop, ready to send. Phone storage thanks you too.

FAQ

Should I use an app or the browser?

Browser is fine for one-off tasks — nothing to install, works on any phone. Apps add convenience for frequent use (notifications, offline). For most people, browser is enough.

Will my signature look professional?

Finger signatures look surprisingly good — often better than mouse-drawn. Practise on a blank page once; once you've got a tidy version, it'll be consistent across documents.

Can I receive a signed PDF back to my phone?

Yes — most email clients and messaging apps preview PDFs and let you save or forward. Save important ones to a cloud folder so they don't disappear when you delete the email.

Your phone is a perfectly capable PDF tool. Open Flint in your browser and finish the job before boarding.
