How It Works

PDF Kit processes files entirely in your browser for maximum privacy and speed.

Step 1

Select Your Files

Drag and drop your files into the converter or click to browse. We support all common image formats (JPG, PNG, GIF, WebP) and PDF files.

Step 2

Configure Settings

Choose your output format, quality settings, and page options. High quality preserves detail while low quality creates smaller files.

Step 3

Browser Processing

Your files are processed entirely in your browser using advanced algorithms. Nothing is uploaded to any server - your files stay private.

Step 4

Download Results

Once conversion is complete, download your files instantly. Multiple files are automatically packaged into a convenient ZIP archive.
