About Convertify
Privacy-first file tools that run 100% in your browser. No uploads. No servers. No compromises.

Our Mission
Convertify was built on a simple belief: essential file tools should be free, private, and accessible to everyone. Too many online converters require you to upload sensitive documents to unknown servers, create accounts, or pay for basic functionality.
We took a different approach. Every Convertify tool processes files directly in your web browser using client-side JavaScript. Your documents — whether they contain tax information, medical records, legal contracts, or personal photos — never leave your device.
With 40+ tools covering PDF manipulation, image conversion, and data format transformation, Convertify serves millions of users who need reliable file tools without the privacy trade-offs.
Why Convertify?
Privacy First
Files are processed 100% in your browser. Nothing is ever uploaded to our servers. We can't see your documents because they never leave your device.
Instant Processing
No waiting for server uploads and downloads. Files are processed instantly on your machine, regardless of file size or internet speed.
Works Everywhere
Use Convertify on Windows, Mac, Linux, iOS, Android, or Chromebook. Any device with a modern browser — no software to install.
No Sign-Up Required
Every tool works immediately without creating an account, providing personal information, or subscribing to anything.
No Limits
No file size limits, no daily usage caps, no watermarks on output files. Use Convertify as much as you need, completely free.
Built for Everyone
Students, professionals, small businesses, and anyone who needs file tools but shouldn't have to pay for basic conversions.

Our Editorial & Testing Methodology
Real-document testing
Every tool is tested on real artifacts before it ships: actual government forms (visa, passport, EPF), large scanned PDFs, design exports from Figma and Sketch, and source code files. We don't just test the happy path — we test 100MB PDFs, multi-language OCR, password-protected files, and broken inputs.
Open-source libraries we trust
Convertify is built on battle-tested open-source: pdf-lib for PDF construction, pdf.js (Mozilla) for rendering, WebAssembly ports of libvips for image processing, and Web Crypto API for AES-256 encryption. No proprietary black boxes.
Security model
We have no servers that touch your files. Period. Open your browser's DevTools → Network tab on any Convertify tool — you'll see analytics requests but never a request that uploads your file. That's the threat model: even if Convertify itself were compromised, your documents would still be safe because they only exist on your device.
Reviewed every quarter
Every tool page and editorial guide has a Last reviewed date. We re-test workflows on the current browser versions and update steps when interfaces or libraries change. If something stops working, please let us know at support@convertify.work.
Who Writes Convertify
Convertify's editorial team is a small group of engineers and writers who use these tools daily on their own documents. Every guide is written by someone who has actually hit the problem they're solving — usually because they got rejected by a government portal or stuck on a 100MB email attachment.
