Short summary

Build a browser-based image-to-PDF converter with Canvas API and jsPDF—no backend, no server costs, no file limits. Code handles aspect ratio, page centering, and multiple images entirely in the client.

  • Pure client-side solution using Canvas API and jsPDF library for zero server infrastructure
  • Includes working implementations for single and multi-image PDFs with aspect-ratio preservation
  • Eliminates upload bandwidth, storage costs, and file size restrictions of traditional backend approaches
