About OneConvertly
The privacy-first file toolkit that processes everything in your browser.
Our Mission
Every day, hundreds of millions of people need to compress a PDF, convert an image, or merge documents. They search online and land on a tool that forces them to upload sensitive files to unknown servers — tax returns, contracts, medical records, personal photos.
We built OneConvertly to eliminate that trade-off. Using modern browser technology (WebAssembly, Web Workers, Canvas API), OneConvertly processes your files directly on your device. Your files never touch a server. No upload wait, no privacy risk, no file size limits.
How It Works
Client-Side by Default
80%+ of all file operations run entirely in your browser using WebAssembly. No upload required — your files stay on your device.
Instant Processing
No upload wait, no queue, no download wait. Most tools complete in under 5 seconds, directly on your hardware.
Always Free
Core tools are free with no daily limits, no signup, no watermarks. No artificial restrictions.
What We Offer
OneConvertly is an all-in-one file toolkit covering PDF, image, video, document, and developer tools — all built with the same privacy-first principle.
Privacy by Architecture
Privacy is not a feature we added on — it is a consequence of our architecture. When files are processed in your browser, there is no technical way for us to access them. We do not store files, we do not log file contents, and we do not share data with third parties.
For tools that require server processing (Word to PDF, HTML to PDF), files are encrypted in transit, processed in isolated containers, and automatically deleted within 1 hour.
