How to add text to a PDF on iPhone or Android

What this workflow helps you do

A phone browser can run Edit PDF without a separate desktop program. Device memory, the mobile file picker, camera permissions, and download handling matter more on a phone, so smaller batches are easier to verify.

Choose a PDF from phone storage, enter new text, position it on the intended page, and save a new copy.

Plan the task in Edit PDF

Place new text on a selected PDF page and control its position, size, and colour. Existing text is not rewritten by this focused editor.

This focused PDF editor adds one new text line to a selected page with position, size, and colour controls. It is useful for short labels, dates, references, or missing notes, but it does not select, delete, rewrite, or reflow existing PDF text.

1. Add text to a PDF page. Choose the page, enter the new text, and position it where it should appear in the output copy.
2. Control text size and colour. Match the addition to the surrounding document as closely as the available standard text controls allow.
3. Choose the correct editor for the document. Use PDF Forms when compatible interactive fields already exist, and use Annotate PDF for a highlight or review note instead of ordinary page text.

Complete the task reliably on a phone

The mobile file picker may show Photos, Files, Downloads, a camera option, or cloud-provider shortcuts depending on the device. Select only the sources required by Edit PDF and return to the browser while processing finishes.

Large documents and high-resolution images use device memory. If the browser reloads or becomes unresponsive, keep the originals and retry with a smaller supported batch rather than repeatedly starting the same large job.

1. Use a current browser and keep the tab active during processing.
2. Save the result to Files or Downloads.
3. Reopen the download outside the tool before sharing it.

Settings and limitations to check

Can I edit PDF text online for free? You can add a new text line to a selected page for free. Existing text cannot be rewritten by this focused tool.

Can I delete or replace words already in the PDF? No. The current editor adds new text and does not alter existing text objects.

Do I need an account to add text to a PDF? No. The document is processed in this browser without registration.

1. Use only the settings needed for the required result.
2. Keep the source file available for comparison.
3. Do not rely on an unsupported exact-size, fidelity, or security promise.

Review the completed file

Open the downloaded PDF on the phone and zoom into the added text.

Open the downloaded result in a separate viewer, inspect important pages or details, and repeat the workflow with adjusted settings if the output is not suitable.

1. Confirm the expected file type and page count.
2. Check important text, images, order, and orientation.
3. Share or submit only the reviewed copy.
