Lifetime licence
$50 once. Yours for life.
Lifetime means lifetime. One payment covers everything Margin1 does today and everything it does next.
Every feature
No Pro, Plus or Business tiers. Text editing, OCR, redaction, batch, forms and signing are all in the one licence.
Every future update
New versions and new features arrive free. No upgrade fees, no "version 2" to buy again.
No other costs
No subscription, renewal, add-ons, cloud fees or cancellation fee. $50 is the whole bill.
Yours, even offline
Use it on up to 3 PCs. The licence is checked on your own computer, so it never needs to phone home to keep working.
What you can do
Small jobs. Clearly handled.
Every one of these is in the $50 lifetime licence, and all of them are in the 7-day trial. Tools marked LIFETIME need the licence once the trial ends; the rest stay free forever.
Edit text & imagesLIFETIME
Fix a typo, change a date, swap a photo. The font stays the font.
Sign PDFs
Draw, type or add an image of your signature. Free, forever.
Fill PDF forms
Fillable or flat, Margin1 finds the fields. Save your details and autofill.
Put pages in order
Merge, split, reorder, rotate. Drag pages between files.
Make your mark
Highlight a line, leave a note, draw or stamp. Export every comment.
Compress with preview
See before and after first. Lossless by default, so nothing goes missing.
OCR scansLIFETIME
Turn scanned pages into searchable, editable text, offline.
Redact for realLIFETIME
Removes the words underneath, not just a black box on top. Hidden data too.
Edit PDF text
Edit PDF text and keep the same font.
Many PDF editors treat each line as a separate scrap of text, so one change breaks the spacing or swaps the font. Margin1 edits the paragraph the way you see it.
Click a paragraph and type. Lines rewrap inside the original box, like a word processor.
The font stays the font. Margin1 reuses the font inside the PDF, or the same font on your PC.
No silent swaps. If a font isn't available, you see what replaced it and how close the match is.
Files don't bloat. Font data is tidied on save, so ten edits don't make a file ten times bigger.
How it works

- 01Choose your PDF
Opens straight away, even long documents. No upload, no sign-in.
- 02Make your changes
Edit, sign, comment or rearrange. Every step can be undone.
- 03Save a new copy
Your original stays as it was, and earlier versions are kept for you.

Adobe Acrobat alternative
How Margin1 compares.
The lifetime price is only half the story. What matters is whether one payment really covers everything.

Less PDF fuss
A few things Margin1 will never do.
Extra costs
$50 once covers every feature and every future update. No renewal, add-ons, upgrade fees or cancellation fee.
AI pop-ups
Margin1 has no AI assistant. Nothing pops up on your files and nothing reads them.
Moving your tools
Updates never rearrange your toolbar. New layouts are yours to opt into.
Reading your files
Documents stay on your computer. We never access, scan or train anything on them.
Nag screens
No upgrade banners, no countdowns and no account needed for the free tools.
Running in the background
Close Margin1 and it's closed. No startup items, no hidden services.
Pricing
One price. For life.
No tiers, no add-ons and no "contact sales". $50 is the only price we charge.

Help
Questions, answered plainly.
Is there a PDF editor with a one-time purchase?
Yes, this one. Margin1 costs $50 USD once, for life. Every feature and every future update is included. There's no subscription, renewal, upgrade fee, add-on or cancellation fee. Try every feature free for 7 days first.
What does "lifetime" mean?
You pay $50 once and keep Margin1 for as long as you use it, including every future version and every new feature. Your licence is checked on your own PC, so it keeps working offline and never needs to phone home.
Are there any other costs?
No. There's no subscription, renewal, upgrade fee, add-on or cloud fee. Every feature is in the $50 lifetime licence.
Can I edit text in a PDF and keep the same font?
Yes. Margin1 edits whole paragraphs, rewraps the lines to fit the original box and reuses the font embedded in the PDF. If a character is missing, it uses the same font from your PC or the closest match, and tells you exactly what it swapped.
Is Margin1 a good Adobe Acrobat alternative?
For most people, yes. It covers what Acrobat Pro is usually bought for: editing text and images, signing, forms, page organising, OCR, compression and real redaction. It runs offline and costs $50 once instead of a yearly subscription.
What happens after the 7-day free trial?
Buy the lifetime licence for $50 to keep every tool. If you don't, reading, commenting, form filling, signing and page tools stay free forever, with no watermark and no reminders.
Does it work offline? Can you see my files?
It works fully offline and your files never leave your computer. Margin1 makes no network calls while you work and has no AI that reads your documents. We never access or scan your files.
How many computers can I use it on?
Up to 3 Windows PCs per licence. Moving to a new PC? Release the old one yourself from your licence page, no support ticket needed.
Does Margin1 work on Mac?
Margin1 runs on Windows 11 and Windows 10 today. A macOS version is on the roadmap.
Pay once. Keep it for life.
Seven days free. Then $50, once, for every feature and every future update. No other costs, ever.
