Edit PDF on iPhone: tap a word and type

To edit a PDF on iPhone, open this page in Safari, pick the file from Files or iCloud Drive, tap the word you want to change and type the new one. TweakPDF rewrites the text that is already in the document, in its own font, and lets you sign with your finger, with no App Store app to install.

Markup adds to a PDF, it does not change it

The Markup tool you reach from the Files app or Mail can put text boxes, shapes, highlights and a signature on top of a PDF. It cannot change text that is already in it.

When the date, the name or the total on the page is wrong, whatever you add sits above the old text, and the old text stays in the file. To fix the mistake, the text itself has to change.

Edit text in a PDF on iPhone, right in Safari

  • Open it from Files

    A phone has no drop area, so tap Choose file: the system picker opens with Files, iCloud Drive and your other locations.

  • Tap and type

    Tap a word, type the replacement and tap Save. Correct as many places as you like.

  • Same font, old letters gone

    What you type takes the font, size and color of the text it replaces and sits on the same line. The old characters are deleted from the file rather than hidden under a patch.

  • Clear an area

    Press Text and draw a frame with one finger to erase or rewrite an area; two fingers scroll the page.

Sign a PDF on iPhone with your finger

Tap Signature, then Add signature, and sign with your finger, or with a stylus on an iPad. You can also type your name in a handwriting style or upload a photo of your signature on plain light paper; the paper is removed and only the ink is kept.

Tap the page where the signature should go, on one page or several. Remember on this device keeps it in this browser only, never on the server. It is a simple electronic signature, not a certified digital signature.

Save the edited PDF back to Files

Once you sign in with Google and download, the PDF goes to Downloads in the Files app, on iPhone and iPad alike. If it is not there, tap Save to…: the share sheet opens, and you can save the file to another place or send it right away.

Good to know first

TweakPDF edits what is already printed on the page. Changing the typeface, reflowing paragraphs, adding or deleting pages, filling in form fields and converting files are outside what it does. A file can be up to 25 MB and 100 pages, and a password-protected PDF needs its password taken off first.

If a word does not respond to a tap, switch on Show text: bright words are editable text, while shaded areas are pictures or blank paper that you edit with a Text frame.

Questions about editing PDFs on iPhone and iPad

Can I edit text in a PDF on iPhone with Markup?
No. Markup in the Files app and Mail adds text boxes, shapes, highlights and signatures on top of a PDF, but it cannot change text that is already in it. In TweakPDF in Safari, you tap the word and type the new one.
Do I need an app to edit a PDF on iPhone?
No. TweakPDF works in Safari on iPhone and iPad, so there is nothing to install from the App Store.
How do I sign a PDF on iPhone?
Open the PDF in TweakPDF in Safari, tap Signature, then Add signature, and draw your signature with a finger. Tap the page where it goes, then download the file. It is a simple electronic signature, not a certified digital one.
Can I edit a PDF on iPad the same way?
Yes. On iPad it works in Safari just as on iPhone: tap a word to change it, sign with a finger or stylus, and find the download in the Files app.
Where is the edited PDF saved on iPhone?
In Downloads in the Files app. If you do not see it there, tap Save to…: the share sheet opens so you can save the file elsewhere or send it.
Is it free to edit a PDF on iPhone?
Yes, 3 files a month are free. You can open, edit and preview the file without signing up and sign in with Google at the download step. Pro, at $6 a month, raises the limit to 1000 files a month.
What happens to my file afterwards?
The server deletes it two hours after you stop working, or straight away if you tap Delete file now. A downloaded file is kept for 24 hours, so downloading it a second time is free.
