Filled and signed in your browser, never uploaded

Fill and sign without printing

Most PDFs that need filling are not real forms, so the usual tools leave you stuck. BitMorph lets you click anywhere on the page to type a name, a date or a note, then add your signature by drawing it or dropping in an image, and download a finished PDF. The whole thing runs in your browser, so the document you are signing, and your signature, never leave your device.

Type anywhere

Click any spot on the page and start typing. No form fields required, so it works on any PDF.

Add today's date

Drop in the date with one click, positioned exactly where you need it.

Draw or upload a signature

Sign with your mouse or finger, or upload a signature image, and place it on any page.

Never uploaded

Everything happens on your device. The file and your signature stay with you.

More than a quick convert

Private by design

Files are encrypted, processed briefly on ephemeral servers, auto-deleted within hours, and never sold or used to train AI.

Precise when it counts

High-fidelity Office conversion rebuilds tables, columns and layout, not just the raw text.

Ready for AI

Turn documents into clean Markdown, JSON or RAG-ready chunks, built to drop straight into your AI pipeline.
