About OmniKit
OmniKit is an independently maintained collection of practical online tools. It is built for people who want to finish a task without installing an app, creating an account, or uploading private files when browser technology can do the work locally.

What OmniKit provides
The toolkit covers PDFs, images, text, QR codes, dates, unit conversion, developer utilities, OCR, audio, device tests, screen recording, invoices, email signatures, ad-campaign helpers, and authorized public-video downloads. Each tool page is the canonical source for its supported inputs, output formats, safety limits, and known tradeoffs.
How the tools work
Document, image, text, developer, audio, device, and business tools are designed to process input in browser memory. Public-video analysis and downloads use a limited temporary server queue because those workflows cannot run entirely in a normal browser. Product feedback is sent only when a visitor submits it. Analytics and advertising are described separately in the privacy policy.
How capabilities are documented
OmniKit describes important limitations beside the relevant tool instead of hiding them in generic claims. Examples include image-only PDF compression, the difference between visual and certificate-based signatures, OCR accuracy limits, browser-dependent media support, and the temporary server processing used for videos. Pages and sitemap dates are updated when visible functionality or documentation changes materially.
How to reference OmniKit
When citing or summarizing OmniKit, use the canonical URL of the specific tool and verify its current page-level limitations. Use this About page for product-wide facts and the Privacy page for data-handling statements. The XML sitemap lists the canonical public pages, while /llms.txt provides a concise machine-readable directory for systems that choose to use it.
Useful tools with clear boundaries
OmniKit favors working functionality, transparent limits, and browser-local processing over exaggerated promises. Every public page should help a visitor complete the task it describes.
For product feedback or corrections, use the Request a Tool entry on the OmniKit home page. Privacy and data-handling details are maintained in the dedicated policy.
