Applications and forms often arrive as a PDF that people print, fill by hand, then scan back in. Depending on the form type, filling it online is much faster.
Forms with fields vs without
Official forms from government offices or companies often come with built-in fillable fields (AcroForm) — click a box and type. A scanned image-based form, on the other hand, has no fields, so you need to place text boxes yourself where the blanks are.
Filling a form with no fields
For a scanned form without fields, use text boxes instead of the fill-form flow, placing each one over the blank line. Zoom in to line things up neatly.
Fill and sign in one pass
If the form ends with a signature line, you can add your signature in the same session and produce one finished file — no shuffling between tools.
