qwiksi

qwiksi is a command-line interface (CLI) tool designed for seamlessly signing PDF documents without the need for a graphical user interface. The tool simplifies the process of digitally stamping a signature on PDFs by allowing users to specify the document directly and applying the signature with ease.

Key Features

• Automatic Form Field Detection: qwiksi automatically identifies and lists fillable form fields in a PDF document, streamlining the signing process.
• Manual Input Support: For flat or scanned PDFs that lack form fields, users can manually designate x/y coordinates to place the signature precisely where needed.
• Signature Generation: qwiksi can generate a signature image from a user's name using a cursive font, making it convenient to obtain a personalized signature.

Usage Overview

qwiksi supports various operations to facilitate PDF signing:

1. Basic opeation: Most modern PDF documents use AcroForm fields, and hopefully the fields are labelled sensibly (a box that needs a signature is named Signature, and so on). If your PDF is using this format, it means that you can just type qwiksi and then follow the prompts.

2. Signature Image Creation: If a signature image does not exist, it can be generated using the following command:

   qwiksi addsig --text "Your Name" [--font 1-6] [--size 100] [--color 000000] [--out signature.png]
   

   Users can select from six cursive fonts (Sacramento, Great Vibes, Qwigley, Satisfy, Allura and Alex Brush) and specify other parameters such as size and color.

3. Checking for Existing Form Fields: To verify if the PDF contains fillable form fields, execute:

   qwiksi fields input.pdf
   

   This will output a list of field names, types, and dimensions, helping users understand where signatures can be applied.

4. Finding Coordinates for Signatures: For documents without fillable fields, qwiksi allows users to find the necessary coordinates for signing:

   qwiksi preview input.pdf --page 1 [--grid 50] [--out preview.pdf]
   

   This command creates a preview with a coordinate grid, aiding in the accurate placement of signatures.

5. Signing the Document: Finally, the signing command is straightforward:

   qwiksi sign input.pdf --signature sig.png --field "Signature" [--output signed.pdf]
   

   For documents lacking form fields, signatures can be directly placed using absolute coordinates:

   qwiksi sign input.pdf --signature sig.png --page 1 --x 150 --y 100 [--width 150] [--height 100] [--output signed.pdf]
   

6. Preview the bundled fonts: Not sure which font you want? Generate a one-page specimen PDF with every bundled font rendering its own name in itself, so you can view them side by side before picking a --font id for addsig/sign below:

qwiksi is built on the robust pdfcpu library, ensuring reliable PDF manipulation and signature placement. This tool is particularly useful for professionals and individuals needing a quick and efficient way to sign PDF documents in a variety of contexts.
