About JubKub
JubKub is an online toolkit for file and text tasks, including images, PDFs, OCR, spreadsheets and everyday calculations. The goal is to help people choose a suitable workflow and inspect the result before using it elsewhere.
Why this site exists
We build tools and guides around concrete tasks, from file conversion and PDF page management to checking text and figures. Guides focus on questions people encounter while using the tools; they are not written to meet a word-count target or to create pages for search alone.
How we check information
Capabilities, supported file types and limits should be described on each tool page. JubKub guides link to relevant tools and advise checking the source and output, especially names, document numbers, amounts and page order.
Processing and privacy
Processing varies by tool. Some tasks run in the browser, and supported files and privacy details can differ. Read the specific tool page and privacy policy before using sensitive documents.
Publisher and sources
The new guide series is published under the JubKub name, and its feature details were checked against the site’s tool pages and source code on the review date shown in each guide. We do not claim an individual author or qualification that has not been verified.
