One PDF only. This browser-only version supports files up to 40MB.
All processing stays local in your browser. Nothing is uploaded.
Current Scope
This version only reads the supported fields from one existing AcroForm PDF, lets you fill them locally in your browser, and exports a new PDF copy.
It is not a signing tool, free-text overlay tool, full PDF editor, validation system, or submission workflow. This version does not handle signatures, flattening, field creation, OCR, form submission, advice, or suitability judgments.
This version supports only the standard field types in the first release: text, checkbox, radio groups, and non-editable, non-multiselect dropdowns. Non-Latin writing, password fields, combed text, option lists, buttons, and signature fields are out of scope.
Trust & Review Reminder
LittleOne is only a tool: your file stays local whenever possible, we do not retain your data, and we do not judge whether your answers are correct. An exported file only means the current browser completed one field-writing pass, not that any agency, system, or recipient must accept it.
Review the content, layout, recipient requirements, and applicability yourself before you submit, print, send, or share the exported PDF.
Waiting for PDF
Upload a regular, unencrypted PDF with a normal structure and existing AcroForm fields.

Unsupported Fields In Scope
Only the existing fields supported in the first release appear here. Any effective change invalidates the old result immediately.
This changes only the download name. It does not mark the current workspace as dirty.
New PDF Ready
If you keep editing fields, the current downloadable result becomes invalid immediately. Review the file yourself before sharing it.
Fill supported fields in one existing AcroForm PDF locally in your browser and export a new PDF copy. It works for forms, checklists, or internal templates that already contain fillable fields. Files are not uploaded. The tool does not add signatures, flatten pages, overlay free text, run OCR, repair fields, or submit forms, so reopen the export to verify it.
