How To
How to Add Text to a PDF Online
Fill in a form, label something, or fix a typo — no software required

PDFs are deliberately hard to edit — but adding a bit of text onto a page shouldn't mean recreating the whole document. Here's how to do it directly, with a free online editor.
What you'll need
- The PDF you want to edit
- A browser
- A minute or two, depending on how much text you're adding
Open the PDF Editor
Go to iguardpdf.com/pdf-editor and upload your file. Every page renders as a preview so you can see exactly where you're placing text.
Choose a text size
Pick Small, Medium, or Large from the toolbar before you start placing text — this sets the size for anything you add next.
Click where you want to add text
Click anywhere on any page and a text box appears right there. Type your text — it stays editable until you're happy with it.
Adjust placement if needed
Drag the small handle on a text box to reposition it, or tap the × to remove it and try again. Nothing is final until you save.
Save your edited PDF
Click Save PDF — your edits become part of the document and it downloads. Turn on Guarded first if the filled-in document needs to be fingerprinted and trackable.
Common mistakes to avoid
•Clicking on the page by accident while trying to select an existing text box — a click on empty space always creates a new box, so click directly on an existing box's text to edit it instead.
•Forgetting to pick a text size before adding a lot of text — you can still resize the whole selection's active preset, but it's faster to set it once upfront.
Beyond this: building a complete workflow
After editing a PDF, these usually come next:
Click, type, save — filling in a PDF shouldn't take longer than that.
Safe in our hands
iGuardPDF takes file handling seriously. A few things worth knowing, whichever tool you're using:
- Every upload and download runs over TLS (HTTPS) — your file never crosses the network unencrypted.
- Files are processed to run the tool you asked for, then deleted. We don't archive uploads or keep a copy afterward.
- Free tools need no account, so there's no identity to build a tracking profile against in the first place.
- Nothing you upload is ever used to train an AI model, ours or anyone else's.
