Browser-local
PayloadIQ Utilities
A private, browser-local toolbox: convert PDF, Word, Excel, PowerPoint, HTML and EPUB files to Markdown, and work with JSON, tokens, encoding, timestamps, regex and hashes.
Everything runs on your device — your files and payloads are processed in the browser and never uploaded to PayloadIQ. No account, no sign-up, no server round-trip.
Build context for LLMs
Turn messy sources into clean, token-efficient Markdown a model can actually use — then validate and inspect the payloads you send it. All in your browser, nothing uploaded.
