An all-in-one online PDF editor with AI chat, quizzes and invoicing
Ask questions about a document and get answers drawn from its content, so long reports and contracts do not need to be read line by line.
Modify text and images directly, add pages, headers and footers, use search and replace, and fill or sign forms with manual or image signatures.
Convert between PDF, Word, JPG and HTML, shrink oversized files, merge or split documents and remove excess pages.
Generate tailored quizzes from source content and create, manage and send invoices from the same platform.

A privacy-first browser toolkit with 100+ PDF, image, developer and AI utilities
PDF, image, developer, finance, business, text and AI utilities share a single interface instead of living across separate sites.
Files are handled on the device rather than uploaded, which suits sensitive contracts, IDs, invoices and internal documents.
Merge, split, rotate, number pages, compress, and convert between JPG and PDF without installing a desktop PDF editor.
JSON, XML and SQL formatting, JWT decoding, hashing, Base64 and URL encoding, minifiers, regex testing and Markdown preview.
