AI Analysis

●●SolidShip ItSolve My Problem

Offline-first browser converter, but remove.bg and CloudConvert already own this space.

Strengths

•Verifiable privacy via Network DevTools inspection; conversion works with Wi-Fi off
•No signup, file size limits, or watermarks; multiple format support (JPG/PNG/PDF/MP4/WAV)
•Uses Canvas API, PDF.js, and FFmpeg.wasm for in-browser processing

Weaknesses

•Crowded category: Squoosh, CloudConvert, remove.bg already handle this well
•Limited format breadth compared to established converters; WebP and SVG support narrow

Post Description

Built this after getting frustrated that every "free" online converter uploads your files to AWS. OneWeeb converts images, PDFs, and audio/video entirely in the browser — Canvas API for images, PDF.js for PDFs, FFmpeg.wasm for audio. The privacy claim is verifiable: open DevTools → Network tab → convert a file. Zero outbound requests during conversion. Or just turn off Wi-Fi after the page loads — everything still works. Supports: JPG ↔ PNG, JPEG → JPG, PDF → JPG, JPG → SVG, WebP ↔ JPG/PNG, MP4 → WAV, image compression to specific sizes (20KB, 50KB, 100KB, 200KB, 500KB). No signup, no file size limits, no watermarks.
