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, image editing, stitching and splitting, local video frame extraction, favicons and app icons, animated GIFs, charts, 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, local video-frame, icon, GIF, chart, 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.
Maintenance, validation, and corrections
OmniKit is an independently maintained tool project. Documentation follows the current tool behavior: what is preserved, what changes, and which inputs are not supported should be explicit.
This set of examples includes original practice files, specific inputs and settings, and downloadable reference outputs. Text and time-zone results are checked against the calculation rules; PDF samples are reopened, checked for page count and text layers, and rendered for inspection. Guides distinguish observed browser runs from reference-environment measurements instead of promising the same outcome for every file.
See the practical guides for check dates, reproduction steps, and known limits. If a guide and tool disagree, use contact and feedback to report the page, steps, and result. Include an email address if you would like a reply.
Latest content update: . Added examples for image compression, PDF compression, word counting, and time-zone conversion.
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.
