About us
One Big File is a free, private platform for converting, compressing, and editing documents and images — straight from your browser. No account required, no files stored permanently.
Most file-conversion tools either require a paid subscription for anything useful, demand an account just to convert a PDF, or quietly process your files on opaque servers. We wanted something different.
One Big File gives you practical tools that work immediately, process files privately, and delete everything when done. Premium plans exist for higher limits — not to lock basic functionality behind a paywall.
Files are processed in isolated workers and deleted automatically. We never read, sell, or retain your documents beyond the retention window.
No heavy desktop software. Open a tool, upload a file, get the result — from any device in seconds.
Every tool is available without an account. Premium tiers exist for higher limits, not to lock basic features behind a paywall.
No forced sign-ups, no hidden upsells, no countdown timers. If it's free, it actually works for free.
65 tools across PDF, image, document, and OCR workflows — all free to use.
Files you upload are processed in isolated workers and never shared with third parties. Temporary outputs are deleted automatically after the configured retention window. We don’t sell data, run surveillance ads, or store your documents beyond what’s needed to complete your job.
