Free tools
Document tools, no signup
Fill and flatten PDF forms, fill Word document templates, and convert between Excel and CSV — free, with no account required. Every tool runs entirely in your browser: your file is never uploaded.
Fill PDF
Upload a fillable PDF, see its detected form fields, fill them in, and download the filled PDF. Your file is never uploaded.
Flatten PDF
Upload a filled PDF form and flatten it so the fields are no longer editable. Your file is never uploaded.
Intake Sheet to CSV
Convert a label/value Excel intake sheet (column A = field, column B = value) to CSV. Not for general multi-column spreadsheets. Your file is never uploaded.
CSV to Excel
Convert a CSV file to a single-sheet XLSX workbook. Your file is never uploaded.
Fill Word Document
Upload a Word form template, fill in the detected fields, and download the completed DOCX. Your file is never uploaded.
Why these are free and account-free
Each tool does its work with client-side JavaScript running in your browser — the same technology FillOnce's encrypted vault relies on. Your file is never uploaded, so there's nothing for us to store and no reason to require an account.
Need to reuse the same information across many forms instead of typing it in every time? Create a free FillOnce vault.
