Fill PDF forms online - complete form fields or type anywhere on the page

Form fields (AcroForm). Many official and business PDFs contain interactive fields. The tool reads each field’s type and current value and lists them grouped by page: single-line and multi-line text boxes (character limits set in the PDF are respected), checkboxes, dropdowns, multi-select list boxes and radio button groups. Read-only fields are shown but locked. Only the fields you actually change are written back, so the rest of the form stays exactly as it was.

Add text anywhere. Plenty of PDFs have no fields at all - scanned paper forms, photos turned into PDF, or documents exported as “flat” pages. In this mode you click the page preview and a text box appears at that spot. You can drag it, change the font size from 6 to 96 pt (12 pt by default), edit the wording in the list below the page or delete it. Text is written in black directly onto the page when you save. You can combine both modes in one document: fill the real fields and add a note or date where the form has no field.

• Application and registration forms downloaded from a government, school or bank website.
• Tax and benefits forms that are distributed as fillable PDFs.
• Contracts, NDAs and leases with blanks for names, addresses and dates.
• Consent forms, permission slips, surveys, warranty claims and return forms.

The tool fills whatever PDF you give it - it does not contain official templates and it does not check whether your answers are correct or complete. Before sending, confirm that the organisation accepts a form filled in this way; some require a handwritten or certified electronic signature. You can add a drawn signature afterwards with Sign PDF.

Flatten the form after filling removes the interactive fields and bakes their appearance into the page. The values stay visible in every viewer, but they can no longer be changed in a PDF reader - a good choice for a final version you send by email. Leave it off if you or someone else still needs to edit the fields.

Standard PDF fonts such as Helvetica cannot show many accented characters, so values and added text are written with the DejaVu Sans font embedded in the file. It covers accented Latin letters (é, ñ, ü, ø, ł), Greek and Cyrillic; Chinese, Japanese and Korean characters are not included. Only the characters you use are embedded, which usually adds just tens of kilobytes. If the finished file is too large for an upload portal, run it through Compress PDF.

Forms often contain personal data - dates of birth, ID numbers, bank details. Here everything is processed by JavaScript in your browser and nothing is uploaded, so the filled document exists only on your device.

• Dynamic XFA forms (used by some older Adobe LiveCycle documents) are not supported; their fields may not be detected. Use “Add text anywhere” instead.
• Digital signature fields are not edited.
• Password-protected PDFs must be unlocked first, for example by opening them with the password and choosing “Print → Save as PDF”.
• Calculated fields and form scripts (such as automatic totals) are not run, so check any sums yourself.
