Migrate from Flash to HTML5

Restore Flash animations, games, and interactive content as HTML5 — working on every modern browser and mobile device.

Migration: Flash to HTML5

From Adobe Flash to HTML5/Canvas/WebGL

Why Migrate

  • Browser Removal: All major browsers removed Flash Player support in 2021. Flash content is completely inaccessible to users.
  • Mobile Compatibility: HTML5 works on iOS and Android natively. Flash never worked on mobile devices, limiting audience reach.
  • Security: Flash had persistent security vulnerabilities. HTML5 runs in the browser sandbox with modern security protections.

Migration Roadmap

  1. Flash Content Audit (1–2 weeks): Catalog all Flash content (SWF files), identify ActionScript versions, and assess complexity of animations and interactivity.
    • Flash content inventory
    • Complexity assessment
    • Technology recommendation (Canvas, WebGL, or framework)
  2. HTML5 Rebuild (3–8 weeks): Recreate Flash content using HTML5 Canvas, WebGL, or frameworks like Phaser/PixiJS for interactive elements.
    • HTML5 interactive content
    • Responsive layouts for mobile
    • Cross-browser test results
  3. Integration & Deployment (1 week): Integrate HTML5 content into existing pages, update embed codes, and verify functionality across devices.
    • Updated web pages
    • Embed code documentation
    • Device compatibility report

Risks & Mitigation

  • Complex ActionScript 3 logic is difficult to port: We use TypeScript for complex AS3 ports with type safety, and Phaser/PixiJS for game-like interactivity that maps well to Flash's display list.
  • HTML5 animation performance differs from Flash: We use GPU-accelerated Canvas/WebGL rendering and optimize frame rates with requestAnimationFrame, achieving 60fps on modern devices.

Estimated Scope

Hours: 80–200 | Cost: $160–$400 | Timeline: 4–10 weeks

Frequently Asked Questions

Can you convert Flash games to HTML5?
Yes. We rebuild Flash games using Phaser or PixiJS, preserving gameplay mechanics, level data, and high-score systems as HTML5 web games.
Can you convert Flash e-learning modules?
Yes. We migrate interactive training content to HTML5 with SCORM compatibility, preserving quizzes, simulations, and progress tracking.
Is automated Flash-to-HTML5 conversion viable?
For simple animations, tools like Adobe Animate can help. For interactive content with ActionScript, manual rebuilding produces much better results.
