DDaverse

DDaverse is a set of 55+ free online tools for PDFs, images, text and Indian finance calculations. Every tool runs entirely inside your browser tab using the Canvas API, pdf.js, pdf-lib and Tesseract.js, so files are never uploaded to a server.

That architecture is what removes the usual limits. There are no daily caps, no per-task file counts, no watermarks on any output, no signup, and no paid tier. File size is bounded only by your device's memory.

Notable features:

• Compress images and PDFs to an exact KB figure, not just "smaller" — ask for 20 KB and the output lands at or under it
• Edit text inside a PDF in place, keeping the original embedded font, size and colour
• PDF to Word that rebuilds paragraphs, headings, tables and lists rather than dumping loose lines
• Photo and signature upload requirements for Indian government exams, read from each exam's official notification, with a checker that validates your file before you submit
• Works offline once the page has loaded, because the processing code is already in the tab
