Why does the tool say no supported fields were found?
Some PDFs look like forms but are actually flat scans or images. This tool needs interactive AcroForm fields such as text fields, checkboxes or dropdowns.

Fill PDF Form
Upload a PDF with form fields, fill them in the preview or in the right panel and save the completed document.
Fill interactive PDF forms directly in the browser
Use Fill PDF Form for documents that contain real AcroForm fields: application forms, onboarding documents, checklists, declarations, simple agreements and PDF templates with text fields, checkboxes or dropdowns. Instead of printing and handwriting answers, fill supported fields on screen and export the completed PDF.
Click fields in the document preview or use the Form fields panel on the right. Text inputs, checkboxes and dropdowns stay synchronized, so changes appear immediately on the preview. If the PDF is only a flat scan without interactive fields, the tool will report that no supported fields were found.

Form data stays in the browser
Your form entries are processed locally. ClickPDF does not upload completed applications, declarations, onboarding forms or personal data to a server. Download the completed PDF before closing the tab because entered values are not stored online.
Fill PDF form questions
Can I fill checkboxes and dropdowns?
Yes. Supported checkboxes and dropdown fields appear in the sidebar and can also be changed from the document preview.
Can I add new fields to a flat PDF?
No. This tool fills existing interactive fields. It does not create new form fields on a scanned or flat PDF.
Will the completed values be saved into the PDF?
Yes. Save and download creates a new PDF with the entered field values written into the document.
