Add Text to PDF

The form that was never made fillable

The most common reason anyone searches for a way to type on a PDF is a form. Somebody designed it in a word processor, exported it to PDF and sent it out, and it has lines and boxes but no form fields — so it cannot be filled in on screen, and the instructions say "print, complete in block capitals, scan and return". Printing, writing and scanning produces a crooked, low-contrast copy that is harder to read than typed text, and it takes a quarter of an hour that a two-minute job does not need.

Typing straight onto the page produces a cleaner document than any pen-and-scanner round trip. Click at the start of each line or box, type, and move on; the zoom control lets you get the text sitting precisely on a ruled line. Because each entry is its own box, you can align a column of answers by dragging, or select one and nudge it a point at a time with the arrow keys.

If the PDF does have real form fields — you can click into them in a PDF reader — use Fill PDF Form instead. It writes into the fields themselves, so the values are recognised by whoever processes the form, while text typed on top of a field is just ink on the page.

Choosing a font, size and position that look deliberate

Text you add is set in one of the three standard PDF families: Helvetica (the same proportions as Arial), Times and Courier, each with bold and italic. Helvetica at 10 to 12 points matches most printed forms; Times sits better against documents typeset in a serif; Courier, which is monospaced, is the right choice for boxes that expect one character per cell, such as reference numbers and dates split into squares, because each letter advances by exactly the same width.

For answers that sit on a printed line, place the box so the bottom of the letters rests just above the line, rather than centring the text on it — that is how handwriting sits, and it reads as filled in rather than overprinted. A slightly darker blue or plain black reads as an entry; mid-grey looks like part of the template.

Multi-line answers wrap automatically once you drag the box's right-hand handle to set a width, and alignment can be set to left, centre or right — useful for centring a title or right-aligning figures in a column.

What happens to the file

Your text is written into the page as real, selectable PDF text, not as a picture of text. Anyone receiving the document can search it, copy it, and read it with a screen reader. The rest of the page — including any existing text, images and vector graphics — is left exactly as it was: nothing is re-rendered, recompressed or rasterised, so the file stays sharp and close to its original size.

The work is done by your browser. The PDF is read into memory on your device, your additions are drawn into it there, and the finished file is handed back as a download, so documents with personal details — benefit claims, visa forms, medical questionnaires, tax schedules — are never sent anywhere.

Characters that the standard PDF fonts cannot represent, such as Devanagari, Chinese or Arabic, are placed as a high-resolution image of the text rendered by your browser. It looks right on screen and in print, but it is not selectable; the save summary tells you when this has happened.

Small things that save time

Duplicate a text box with Ctrl+D to reuse its style for the next entry; the next new box also starts in whatever style you used last. Double-check dates and numbers in the preview before downloading — the preview shows the real saved pages, not the editor's approximation of them.

If you need to sign the same form, the Sign tool in the same toolbar draws or types a signature and places it as an image, so the form can be completed and signed in one pass. If you need to change printed text on the form rather than add to it, the Edit text tool replaces existing lines properly.
