The problem
Print it, sign it, scan it, send it back
Most forms still arrive as PDFs you can't type into, and the quick online fixes want your personal details on their servers.
The print-and-scan shuffle
Print the form, fill it in by hand, sign it, scan it crooked, then email a blurry copy back.
Your details on someone's server
Online sign tools want the whole form, with your address, date of birth and licence number, uploaded first.
Text that won't sit on the line
On a flat form you get a floating text box, nudged by hand until it almost lines up with the blank.
A subscription to sign your name
Signing services are built for businesses sending contracts, and are priced by the month to match.
Daily caps and sign-ups
Create an account, confirm your email, then find the free plan ran out after one document.
Typing the same details again
Name, address, email, phone, date of birth: every form asks, and every time you type it all from scratch.
Vow PDF Sign & Fill fixes all of it.
How it works
Open. Fill. Sign.
The Fill tool is on when the form opens, the blanks are already found, and Sign here is one click.

Features
Every form, filled in neatly
For tenants, parents, job seekers, contractors and offices that live on paperwork.
Finds the blanks for you
Blank lines, underscores, boxes, table cells, check boxes and letter boxes are found on flat forms and scans alike, and outlined.
Text that sits on the line
Typed text snaps onto the line at the right size, fits its box, and goes one letter per box in postcode and date combs.
Fillable forms too
Text fields, check boxes, radio buttons, drop-downs and lists, with Tab order, required fields marked and read-only fields respected.
Fill my details
Keep your name, address, email, phone and date of birth once, and fill matching fields in one click by their names or printed labels.
Signatures that look like yours
Draw it with ink that thins as you write faster, type it in a handwriting font, or photograph it on paper and the paper is made transparent.
Sign here, found
"Signature", "Sign here", "Initials" and "Date" labels get an orange tag that places your signature, initials or today's date in one click.
Digital ID signatures
Certificate signatures (PKCS #7, SHA-256) with an ID from Windows, a .pfx file or a personal ID made in the app, with an optional time-stamp.
Checks others' signatures
Every digital signature in an opened PDF is checked: unchanged or changed after signing, trusted or self-signed, who signed and when.
A to-do list for every form
Fields, required fields and sign-here places are listed with progress, and Next to do jumps to whatever is still blank.
Light and dark theme
Switch between the light and dark look with one click on the Light / dark button, or let it follow your Windows setting.
Light & dark theme
Easy on the eyes, day or night.
PDF Sign & Fill comes with a crisp light theme and a calm dark theme. Switch with one click, or let it follow your Windows setting by itself. It remembers your choice.

FAQ
Questions about PDF Sign & Fill
Is Vow PDF Sign & Fill free?
Yes. Every fill and sign feature works on 3 documents a day, reset at midnight, with one saved signature and one set of initials. Opening and filling in are always free; only saving, printing or digitally signing a changed document counts. Unlimited, a one-time $4.95 USD payment, removes the limit and adds a signature library, date stamps, flattening and batch signing.
Can I type on a PDF that isn't a fillable form?
Yes. Blank lines, boxes, table cells, check boxes and letter boxes are found on the page, on PDFs from any program and on scans, so you click a blank and your text sits on the line at the right size.
Does it upload my documents?
No. Everything happens on your own PC. There is no account and no cloud. The only optional connection is a digital signature time-stamp, and only when you tick it.
How do I add my signature?
Draw it with the mouse, a pen or your finger, type your name in a handwriting font, or take a photo of your signature on paper and the paper is made transparent. It's kept on your PC for next time.
Is a drawn signature a digital signature?
A drawn or typed signature is a picture of your handwriting on the page. For a certificate-based digital signature, use Digital ID with an ID from Windows, a .pfx file or a personal ID made in the app. Vow also checks the digital signatures already in a PDF.
Will it change my original PDF?
No. By default the signed copy is saved next to the original as "name (signed).pdf" and the original stays blank. You can also save over it, and a backup is kept.
How is it different from Adobe Acrobat Reader or DocuSign?
Acrobat Reader's Fill & Sign is free for filling in and your own signature; Vow adds blanks found on flat and scanned forms, Sign here tags, one-click autofill and batch signing. DocuSign is a subscription for sending documents to others to sign; Vow is for filling and signing yourself, offline, for $4.95 once.
Is it safe to install?
Yes. It is made and published by XTO Pty Ltd, an Australian company. There are no ads, no bundled software and no account, it needs no administrator rights, and it uninstalls cleanly from Windows Settings without touching your PDFs.
