As answered by people managing CSSViewer and Convertful.app.
Convertful.app's answer:
Everything runs entirely in the user's browser. Unlike every major competitor (iLovePDF, Smallpdf, CloudConvert), files are never uploaded to a server. This means instant processing, complete privacy, and zero file size restrictions — all powered by WebAssembly and browser APIs.
Convertful.app's answer:
Competitors upload your files to their servers, charge $7-21/month for full access, and impose daily limits on free tiers. Convertful processes everything client-side, so it's faster, more private, and completely free. No account required to start using tools.
Convertful.app's answer:
Anyone who needs to convert, compress, or edit files quickly — freelancers, designers, developers, students, small business owners, and content creators who value privacy and don't want to pay for basic file operations.
Convertful.app's answer:
We got tired of paying monthly subscriptions just to compress a PDF or convert an image. Every competitor uploads your files to their servers, which is slow, expensive to run, and a privacy concern. We realized modern browsers are powerful enough to handle all of this locally — so we built Convertful to prove that file conversion can be free, instant, and private.
Convertful.app's answer:
Next.js, React, TypeScript, WebAssembly (FFmpeg for video, Tesseract.js for OCR), Canvas API, Web Crypto API, pdf-lib, Tailwind CSS. Hosted on AWS.
