As answered by people managing Convertful.app and SuperDev Pro.
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.
