Filling a PDF that has no fields

Most official PDFs are not fillable. They are pictures of paper. You can still write on them, and still do it a hundred times.

Two kinds of PDF that look alike

On screen they are identical. In use they have nothing in common.

A fillable PDF contains real input areas. You click into one, a cursor appears, you type. The file knows where its fields are and what they are called.

A flat PDF has none of that. It is a drawing. Clicking does nothing. It came from a scanner, a print-to-PDF, an export out of a layout program, or an authority that published it that way.

To find out which you have, open the file and try clicking where you would write. If nothing happens, it is flat.

What you do instead

You draw the fields yourself, on top of the displayed page. Each rectangle you draw becomes an area where text will be written, as though the form had been built for it.

1. Open the PDF; it appears page by page.
2. Drag a rectangle where the information belongs and give it a name. The spreadsheet column name is the handy choice, because the mapping then happens on its own.
3. Set the text size, the alignment, and what should happen when a value is too long: shrink it, wrap it, or clip it.
4. Repeat for each piece of information.

On an ordinary form this takes a few minutes, and you do it once. The template is saved, reopens, and can be exported to a file you keep for next year or hand to a colleague.

Character boxes

Plenty of official forms ask for one letter per box. Drop an ordinary text area over them and the letters land wherever they like, which is unreadable.

There is a field type for exactly this. You say how many boxes there are and where they sit, and each character centres itself in its own. The result follows the printed grid.

When the scan is crooked

There is no trick for this. A page scanned at an angle stays at an angle, and fields drawn on it will follow. Two ways out.

Straighten the scan first, using whatever software did the scanning. Most will do it automatically.

Or find the original. Many official forms are published as clean PDFs by the body that issues them, which always beats a photocopy of a photocopy.

What comes out

One PDF per row, with real text embedded in the file rather than a picture pasted on top. The result can be selected, searched, and printed at full resolution.

Accented characters and names from any language work: the font needed is embedded in each document, which is what guarantees it looks the same on the machine of whoever receives it.
