Is OmniKit safe to use with confidential files?

Yes, 100%. OmniKit performs all operations strictly within your browser (Client-Side). Your photos, documents, tokens, and recordings never touch remote servers.

Are there file size limits or usage restrictions?

No queues and no artificial limits. Processing speed depends entirely on your local hardware, so you can process files free of charge without restrictions.

Does OmniKit work offline?

Yes! OmniKit is built as a Progressive Web App (PWA). Once loaded, the utilities remain fully functional even when offline.

What formats are supported?

OmniKit supports iPhone HEIC, HEIF, WebP, PNG, JPG, SVG, PDF, CSV, JSON, TXT, Markdown, Neural OCR text extraction, and Screen Recording in WebM and MP4.
