Frequently asked questions
Are my files uploaded to a server?
No. Every tool runs in your browser. Files are read locally and the result is generated locally.
Is there a size limit?
There is no server-side limit. Practical limits come from your device memory; desktop browsers typically handle documents of several hundred megabytes.
Does it work offline?
Yes. Once loaded, no network access is required.
Is it free?
Yes — free to use, and the source is open so you can self-host or modify it.
Which browsers are supported?
Any modern evergreen browser with WebAssembly support: Chrome, Edge, Firefox and Safari 15+.
