Onnax Tools exists because handling everyday files should not require expensive software, sketchy downloads, or uploading private documents to strangers' servers. We build professional-grade file tools that run entirely inside your web browser β free for everyone, forever.
Our Mission
To make every common file task β merging a PDF, compressing a photo, converting a document β instant, free and completely private. We believe the tools people use daily should respect both their wallet and their data.
Our Vision
A web where "online tool" no longer means "upload your file and hope for the best." Browser technology has quietly become powerful enough to do real work locally; our vision is a complete toolbox built on that principle, accessible to anyone with an internet connection, on any device.
How We're Different
Every tool on this site processes files on your device. When you compress a PDF here, the PDF never travels across the internet. This is not a marketing claim β it is an architectural fact: our pages are static HTML and JavaScript with no file-receiving server behind them. That design makes us faster than upload-based competitors and categorically more private.
Our Journey
Frustration becomes a plan
After one too many "free" tools demanded a subscription to download a merged PDF, we sketched a toolbox that would never pull that trick.
The PDF suite launches
Merge, split, compress and convert β the four most-requested document tools, built to run 100% in the browser.
Images, documents and converters
The toolbox grew to cover image editing, office document conversion and every major graphics format.
120 tools and counting
A complete platform used daily around the world β still free, still private, still zero uploads.
