My dear brother. This the new scope of work for Convert.ist
Full List of Conversions for 20 Browser-Based Tools, Dear Brother!
Dear Muhammed,
You’re my incredible brother and an amazing web developer, and I’m so grateful to work with you on this. I love and appreciate you so much for bringing your skills to this project! I’ve finalized the plan to replace 494 individual web conversion tools with 20 universal tools, all built using HTML and JavaScript to run in the browser without external APIs. Below, I’ve listed each tool and the specific conversions it will handle (e.g., EML to PDF, JPG to PNG), so you can see exactly what each tool does to cover all 494 conversions. I’ve also included performance guidelines to keep everything fast. Let’s make this the best conversion suite ever!
Project Overview
Goal: Build 20 browser-based tools (HTML + JavaScript, no APIs) to cover 494 file format and data conversions. Each tool handles a category of conversions (e.g., documents, images) with a consistent UI (drag-and-drop, dropdowns, tabs, preview panes).
Key Requirements:
- Browser-Based: All conversions run client-side using JavaScript/WebAssembly, no API calls.
- No Server Processing: Server only serves static HTML, JS, CSS (use a CDN for speed).
- Offline-Capable: Tools work offline once loaded (consider Service Workers or PWA).
- UI Consistency: Use drag-and-drop for file uploads, dropdowns for format selection, tabs for options, preview panes, progress bars, and download buttons.
Why 20 Tools?
- Efficiency: Consolidates 494 tools into 20, reducing development and maintenance effort.
- User Experience: Clean navigation avoids the clutter of 494 pages.
- Performance: Shared logic and fewer pages ensure fast operation.
- Scalability: Easy to update or expand.

Technical Implementation
To ensure all tools run in the browser without APIs:
- JavaScript Libraries:
- Documents: pdf-lib.js, docx.js, mammoth.js
- Images: sharp.js, Canvas API
- Video/Audio: ffmpeg.wasm
- Data: PapaParse, js-yaml, xml-js
- Text: js-base64, he
- Units/Math: Pure JavaScript
- Bundle libraries; tree-shake unused features.
- WebAssembly: Use ffmpeg.wasm, sharp.js for heavy tasks.
- Browser APIs: FileReader, Blob, Canvas for file handling.
- Niche Formats: Use intermediate conversions (e.g., AZW3 via EPUB) for formats lacking libraries.
Performance Guidelines
To ensure fast operation:
- Lazy-Load: Load conversion logic on demand (e.g., WebP code) using dynamic imports.
- File Handling: Process large files in chunks; use Web Workers; limit to 100MB.
- UI: Use Preact or vanilla JS; ensure mobile-friendly, accessible design.
- Cache/Preload: Cache dropdown data in localStorage; preload popular tools.
- Server: Serve assets via CDN with HTTP/2, Gzip/Brotli.
- Test: Test on low-end devices and browsers; use Lighthouse; monitor Core Web Vitals.
Action Items
- Map Conversions: Verify all 494 conversions are covered by creating a spreadsheet mapping each to one of the 20 tools. Share with me if you need validation.
- MVP: Start with high-demand tools (Document, Image, Video, Audio Converters).
- UI Design: Build consistent UI with mockups if possible (I can help with mockups).
- Performance Audit: Test large files (e.g., 100MB video) on low-end devices; aim for 5–10 second conversions.
Next Steps
Please confirm you’ve received this and share your timeline for:
- Mapping the 494 conversions.
- Building the MVP (e.g., top 5 tools).
- Performance testing.
If you need sample code, UI mockups, a spreadsheet, or a performance checklist, let me know, and I’ll get them to you. I’m so excited to see this come to life with your genius, Muhammed. You’re the best brother and developer I could ask for!
With all my love and appreciation,
David
