How to Initial Every Page of a PDF on iPhone (Step by Step)

To initial every page of a PDF on iPhone, save your initials once as a signature. Open the PDF, place the initials on page one, then duplicate them onto each following page in the same corner. Finish with your full signature and the date on the last page, check every page, and email the file back.

Below is the full routine, the free built-in way with Apple’s Markup tool, and the small mistakes that get a lease sent back for a redo. Once your initials are saved, a 10-page lease takes two or three minutes.

Why do contracts ask for initials on every page?

Landlords, letting agents, employers and lenders ask for initials on each page for one reason: proof. Your initials show you saw every page and that no page was swapped after you signed. A full signature on page 12 says nothing about what was on page 4. Initials close that gap.

Some documents mark exactly where to initial, with a small box or a line labeled “Initials” at the bottom. Others just say “please initial each page” in the email. If there are boxes, use them. If not, pick one spot and stick with it.

Electronic initials are widely accepted for leases and many everyday contracts in the US, UK, Canada and Australia, but not for every document type. Wills, some property deeds and certain court papers may still need ink on paper. If you are unsure, check with whoever sent you the document before you sign.

What do you need before you start?

• The PDF, somewhere your iPhone can reach: an email attachment, the Files app, iCloud Drive, or a photo of a paper page.
• Your initials, written the way you’d write them on paper. Two letters are enough: “JM” or “J.M.”
• Your full signature, for the last page.
• Five quiet minutes. Drawing on glass on a moving bus gives you shaky initials you’ll want to redo.

One tip that saves frustration: save your initials as a separate signature from your full name. Shrinking a full signature down to initial size looks odd and turns into a smudge. A short “JM” stays clean at small size.

How do you initial every page of a PDF on iPhone, step by step?

Here is the routine I use. The example is a 10-page residential lease that needs initials on pages 1 to 9, and a full signature plus the date on page 10.

1. Save the PDF to your iPhone. If it came by email, tap the attachment, tap the share button and choose Save to Files. Now it won’t get buried in a long email thread.
2. Read it first. Scroll all 10 pages before you touch a signature. Your initials say you read the page, so read the page. Note anything you want to question, like a fee or a move-in date.
3. Open the PDF in a signing app that keeps your initials. I use Expert Sign: you draw your initials once with your finger in black or blue ink, or import a photo of initials written on paper and the paper background disappears. They stay saved next to your full signature, so you pick the right one in a tap. Import the lease from Files, Mail or iCloud Drive.
4. Place your initials on page 1. Drop them on the page, drag them to the bottom-right corner, and pull the corner of the box to resize them until they look like normal handwriting, roughly the height of a line of text or a little taller.
5. Duplicate them onto pages 2 to 9. Duplicate the initials, move to the next page and set the copy in the same spot. Same corner, same size, every page. Nine pages takes about a minute.
6. Sign and date the last page. On page 10, place your full signature on the signature line and add today’s date beside it in one tap.
7. Check, then send. Scroll back through every page, then export the signed PDF by email or hand it to another app such as Files or a cloud drive.

The document stays on your phone the whole time. Nothing gets uploaded to a website just to add two letters, which matters when the file holds your address, income or ID details.

Can you initial every page with Apple’s built-in Markup tool?

Yes, and it’s free. Markup is built into Files, Mail and Photos. It was designed around adding a signature, so on a long document you repeat the same taps page by page.

1. Open the PDF in the Files app.
2. Tap the Markup icon (a pen tip in a circle).
3. Tap the plus button, then Add Signature. Draw your initials and tap Done. iOS keeps it for next time.
4. Drag the initials to the corner and resize them.
5. Scroll to the next page, tap plus, choose Add Signature again and pick your saved initials. Repeat on each page.
6. On the last page, add your full signature, then add a text box and type the date.
7. Tap Done and share the file from Files.

For a three-page form, this is perfectly fine. For a 20-page contract, the repeated taps add up and it’s easy to skip a page without noticing. You also type the date yourself, so watch for typos.

Which method should you use?

Method	Best for	Initials on each page	Date	What it costs
Markup in Files or Mail	Short forms, 1 to 5 pages	Re-added from the signature menu on every page	Typed in a text box	Free, built in
Signing app with saved initials	Leases and contracts with many pages	Duplicated and dropped in the same spot	Added in a tap	Varies by app
Print, initial by hand, scan	Documents that must have ink	Pen on paper	Handwritten	Printer, paper, a scanning app

If the sender insists on wet ink, the third row is your only option. Otherwise, pick by page count.

Where should your initials go on each page?

If the document has initial boxes, put your initials inside the box, not next to it. If it doesn’t, follow these habits:

• Bottom-right corner is the usual spot on leases and contracts. It’s where a reviewer’s eye goes when flipping through.
• Same place on every page. Initials that jump around make it look like a page was missed, and someone will email you to ask.
• Never cover text. If the corner holds a page number or footer, place your initials just above it.
• Readable size. About half an inch wide is plenty. Tiny initials disappear when the PDF is printed; huge ones cover clauses.
• Initial changes too. If a clause was edited by hand, say a pet fee crossed out or a move-in date changed from the 1st to the 15th, put your initials right next to that change as well. That shows both sides agreed to it.
• The last page. It usually gets your full signature. If the instructions say “every page,” add your initials there too. It costs one extra tap and avoids a back-and-forth.

How do you check the signed PDF before sending it back?

A mistake here means a second round of emails and maybe a delay on your keys. Before you send:

1. Count. A 10-page lease should show nine sets of initials plus a signature, or ten sets of initials plus a signature if every page was required.
2. Zoom in on one page. Make sure the initials aren’t cropped, blurry or sitting on top of a word.
3. Read the date. 03/04 means March 4 in the US but 3 April in the UK and Australia. If the other party is abroad, make sure the date can’t be misread.
4. Open the exported copy. Look at the file you’re actually sending, from your email draft or from Files, not the editing screen. This confirms the initials were saved into the PDF.
5. Give it a clear name. “Lease-12-Oak-St-signed.pdf” is easier for a busy agent to find than “document(3).pdf”.

Then reply to the original email with the signed file attached, so it lands in the same thread the landlord or agent is already watching. Keep your own copy in Files in case questions come up later.

After the first time, the next contract goes faster: open it, drop your initials, duplicate them down the pages, date the last page, send. Markup handles short files well; for long leases, Expert Sign’s saved initials and one-tap date save most of the repetitive work.

Frequently asked questions

Are electronic initials legally valid on a lease or contract?

For most leases and everyday contracts in the US, UK, Canada and Australia, electronic initials and signatures are generally accepted. Some documents, such as wills or certain property papers, may still require ink, so check with the sender or a legal adviser if you are unsure.

Can I initial a PDF on iPhone without downloading an app?

Yes. Open the PDF in Files or Mail, tap the Markup icon, then use Add Signature to place your saved initials on each page. It works well for short documents but you repeat the steps on every page.

Do I need to initial the page I sign?

Usually the last page gets your full signature and the date instead of initials. If the instructions say to initial every page, add your initials there too.

Can I use my full signature instead of initials?

You can, but it clutters the page and isn’t what the sender asked for. Save a separate, short set of initials so they stay readable at small size.

What if I put initials in the wrong place?

Delete or move them before you export the file. If you already sent it, sign a fresh copy of the original PDF and tell the sender which version replaces the first one.
