Capabilities

Everything you need to finish the document

A focused toolset that does the common PDF jobs well — and keeps your data on your machine.

Add text anywhere

Drop editable text on any page with control over font, size, and color. Standard PDF fonts embed cleanly on export.

Real signatures

Draw with your mouse or finger, type in a handwriting font, or upload an image. Place it exactly where it belongs.

Drag to position

Move and resize every element with pixel precision — works with both pointer and touch, with keyboard nudging too.

Zoom & multi-page

Navigate long documents with page thumbnails and smooth zoom, so you always edit at the right level of detail.

Pixel-accurate export

Download a flattened PDF where text and signatures land exactly where you placed them — no surprises.

Private by design

Everything runs locally in your browser. Files are never uploaded, stored, or shared. Privacy is the default.

Workflow

Three steps, start to finish

  1. 1

    Upload

    Drop a PDF or pick one from your device. It opens instantly — and stays entirely on your machine.

  2. 2

    Edit & sign

    Add text, draw or type a signature, then drag and resize each element exactly where you want it.

  3. 3

    Export

    Download the finished PDF with everything flattened in place. No upload, no waiting, no watermark.
