Detects form fields, checkboxes and signature · Local
Upload a PDF: if it contains form fields (AcroForm), the tool detects them automatically — text boxes and checkboxes become immediately fillable by clicking on them. You can also draw a signature with your finger or mouse and drag it wherever you like, or add free text anywhere on the page. Everything happens in the browser with pdf-lib and PDF.js, with no upload.
If the PDF is a scan or photo of a paper form, with no clickable fields, the tool switches to manual mode: click anywhere on the page to place text or a signature exactly where you need it, with full control over the result.
Unlike many online form fillers that upload your document to a server, your PDF stays on your device from start to finish — ideal for forms with sensitive data, medical reports, or personal documents.
This tool fills in PDF forms — with or without form fields — directly in your browser, adding text, checkboxes, and a signature without sending the document to a server.
Yes. If the PDF doesn't contain form fields (AcroForm) — for example because it's a scan or a photo — the tool automatically switches to manual mode: click anywhere on the page to place text or a signature exactly where you need it.
You can draw a graphic signature with your finger or mouse and drag it to the desired spot on the document. This isn't a qualified electronic signature with legal value, but a visual signature, suitable for most non-legally-binding forms.
No. All processing happens in your browser via pdf-lib and PDF.js: your file never leaves your device, making it suitable even for documents with sensitive data like medical reports or contracts.
The result is a filled PDF, downloadable directly to your device, which keeps the document's original formatting with the text fields, checked boxes, and inserted signature.
