Fillable versus flat forms
Many official forms — bank, insurance, tax, admission and job forms — are made as fillable PDFs with real fields. Others are flat: they only look like forms. This tool works with real fillable fields; for flat forms, Edit PDF lets you type text anywhere on the page.
How it works
Choose the PDF, and its fields are detected automatically: text boxes, checkboxes, radio buttons, dropdowns and lists. Fill them in, then download the completed PDF. Read-only fields stay unchanged. Tick “flatten” to lock the answers into the page so they can no longer be edited.
Limits to know
Forms built with the older XFA technology (often from some government and Adobe LiveCycle systems) are not supported — open those in Adobe Reader. Some form fields use fonts that cannot display letters such as Hindi or Tamil; if that happens, the tool shows a clear message instead of saving broken text.
Common problems and how to fix them
“No fields found”: the form is flat — use Edit PDF. Text is cut off in a box: the field is small; shorten the text or use abbreviations. Checkbox answers look different in another viewer: open the filled PDF in Adobe Reader or a browser to confirm.
Good habits
Keep an unflattened copy in case corrections are needed, double-check names and numbers, and flatten only the final version before sending.
