Fill a PDF form without uploading it.
KeptPDF auto-detects fillable fields in your PDF. Type in the boxes, check the checkboxes, add your signature, then download. Your form data never leaves your device.
A form you're filling out is personal by definition.
Tax forms, medical intake forms, legal documents, employment applications: the forms you need to fill are almost always the ones you'd least want uploaded to a third party. KeptPDF fills forms in your browser so the data you type stays on your device.
A form you're filling out contains your personal information. It shouldn't need to pass through someone else's server to get your answers into it.
KeptPDF reads the PDF's form structure locally, lets you fill each field in your browser, and bakes the results into the file, all on your device. There's no server step. Watch the Network tab while filling a form and your form data never appears in a request.
