About OmniDeck

Why this exists

Most online tool sites work the same way — you upload your file, it goes to their server, something happens there, and you get a result back. You have no way of knowing what happened to your file in between, how long it was stored, or who had access to it. For a PDF invoice, a client contract, or a password hash, that's a real problem.

OmniDeck works differently. Every tool here runs entirely inside your browser using native web technologies — the Web Crypto API for hashing and encryption, canvas for image processing, WebAssembly-backed libraries for PDF manipulation. There is no upload step because there is no server to upload to. When you compress a PDF here, the file never travels anywhere. When you generate a password, it exists only in your browser's memory and disappears when you close the tab.

This isn't a marketing angle. It's an architectural constraint the entire project is built around, and it's the reason certain features you might expect simply don't exist here: anything requiring a backend was ruled out from the start.

Who builds it

OmniDeck is built and maintained by AAPD Studio, which has been building software professionally for around two decades, mostly on the web. OmniDeck grew out of a set of utilities that kept getting rewritten across different projects — rather than rebuild the same JSON formatter or timestamp converter for the fifth time, AAPD Studio started consolidating them into one place, then kept going.

Every tool is written from scratch or built on well-established open-source libraries. There is no white-label script behind this, no purchased template, no generated filler. If a tool has a limitation, the documentation says so plainly — the PDF compressor, for example, only recompresses JPEG images inside a document and states exactly that, rather than promising universal compression it can't deliver.

What it costs

Nothing, and there is no account to create. There is no free tier with a paid upgrade behind it, no usage limit, no email capture before you can use a tool. The site is supported by advertising, which is kept out of the working area of each tool.

Language support

Every tool, description and help text is available in English and Spanish. Language is detected from the URL, so /json and /es/json serve the same tool with fully localized content.

Technical notes

OmniDeck runs on Cloudflare Workers, which serves the site from data centers close to wherever you are. Pages are static HTML with no client-side framework — that's why they load quickly even on slow connections. The tools themselves are vanilla JavaScript, loading external libraries only where genuinely necessary (PDF manipulation, tokenization, cryptographic operations not covered by the browser's own APIs).

Analytics are limited to aggregate page views. There is no user profiling, no cross-site tracking, no session recording, and no way for us to see what you typed into a tool — because that data never reaches us in the first place.
