Frequently asked questions
What is FormDD?
FormDD is software for filling and managing PDF forms. You mark text positions once, then reuse the same form whenever you need it.
Can FormDD fill PDFs in Thai?
Yes. FormDD supports Thai text in PDF documents.
Can I make certificates from Excel?
Yes. You can use names from Excel to generate many documents at once, such as certificates, diplomas, or any form where each person has different data.
How is FormDD different from filling a PDF the usual way?
FormDD can save the fill positions as a template and reuse them on the same form layout.
Do I have to upload the PDF to the internet?
The main work happens on your computer, so you do not need to upload the PDF to an online service to fill it.
Can I use FormDD with official or government forms?
Yes, if the document is a PDF that needs text or data in fixed places. FormDD helps you avoid repeating the same fill work.
What is Quick Fill?
Quick Fill is for documents you only need to fill once. You do not have to create a lasting template first.
Can I use my own font, or fill in Chinese, Japanese or Korean?
Yes. Upload your own TTF font in Settings and choose it per field. Set the uploaded font on the field before typing, since the built-in default fonts have no Chinese, Japanese or Korean characters. FormDD warns you before creating the PDF if a field's font is missing any characters. Right-to-left scripts such as Arabic are not supported yet. Use a static .ttf file up to 25 MB; .otf, .ttc and variable fonts are not accepted, so the Chinese and Japanese fonts built into Windows (.ttc) cannot be used — download Noto Sans SC, TC or JP from Google Fonts instead and use a file from its static folder (for example static/NotoSansJP-Regular.ttf, not the VariableFont file).
