About SK1 to PNG Conversion

SK1 is the native format of the sK1 open-source vector illustration application, designed for Linux-based prepress workflows with CMYK support and ICC color management. The format stores vector paths, text, fills, and professional color definitions in a Python-serialized structure. PNG (Portable Network Graphics) is the universal lossless raster format supported by every device, browser, and application.

Converting SK1 to PNG rasterizes the vector design into a universally shareable image — ideal for previews, web publishing, social media, and any context where the recipient cannot open SK1 files.

Why Convert SK1 to PNG?

The sK1 application has a niche user base. Virtually no one outside the sK1 community can open SK1 files. Converting to PNG produces an image that anyone can view on any device. For client review, portfolio display, documentation, or web publishing, PNG provides the universal output format.

PNG's lossless compression and alpha transparency make it the ideal raster output for vector designs. Logos with transparent backgrounds, illustrations with sharp edges, and graphics with crisp text all render perfectly in PNG without JPEG compression artifacts.

Common Use Cases

  • Generate PNG previews of sK1 designs for client approval via email
  • Export sK1 illustrations as PNG for web page embedding
  • Create PNG versions of sK1 logos with transparent backgrounds for branding
  • Convert sK1 technical diagrams to PNG for documentation and reports
  • Produce PNG thumbnails of sK1 prepress layouts for project management

How It Works

LibreOffice imports the SK1 file and rasterizes the vector content at the specified resolution. The output is a 32-bit RGBA PNG (24-bit color + 8-bit alpha transparency) with lossless DEFLATE compression. Anti-aliasing smooths vector edges for clean rendering. Resolution determines output quality: 150 DPI for screen use, 300 DPI for print-quality rasterization.

Quality & Performance

PNG output faithfully represents the SK1 vector content as a high-quality raster image. Colors, gradients, and transparency render accurately. The main trade-off is that PNG is a raster format — once converted, the image cannot be scaled up without pixelation. Choose resolution appropriate for your use case.

Tips for Best Results

  • 1Use 300 DPI for any PNG that will be printed — 150 DPI is fine for screens
  • 2PNG preserves transparency — ideal for logos that need to sit on colored backgrounds
  • 3Keep the original SK1 file for future edits — PNG cannot be converted back to vector
  • 4For web use where file size matters, consider converting to WebP instead of PNG
  • 5Verify color appearance if the sK1 design uses CMYK prepress colors

SK1-to-PNG conversion produces universally viewable raster images from sK1 vector designs, with lossless quality and full transparency support.

Frequently Asked Questions

Yes. PNG supports full 8-bit alpha transparency, so logos and graphics with transparent backgrounds export correctly.
150 DPI for screen and web. 300 DPI for print. Higher resolution means larger files but more detail.
No. PNG is a raster format — the vector information is lost during rasterization. Keep your original SK1 file.
PNG files from vector designs are typically compact because large areas of solid color compress well with DEFLATE.
PNG uses RGB color. CMYK values are converted to RGB, which is standard for screen display.
