Chai PDF

Split, merge, compress & watermark PDFs — one or many files, all in your browser.

Files stay on your device. Upload one or many PDFs — each tool outputs one or more files as needed.

Tools in this suite

PDF Splitter
Each comma-separated group becomes its own PDF. Use single pages (1) or ranges (2-3, 9-11).
PDF Merger
Combine PDFs in order, or split into grouped outputs. Unlock password-protected files.
PDF Compress
Reduce file size by lowering page resolution — best for scans and photo PDFs.
PDF Watermark
Add text watermarks to one or many PDFs — nothing uploaded.

Included free

Miniapps & browser tools — not sold separately

ChaiSaab miniapps and in-browser tool suites — Chai PDF, Chai Images, Chai Media, Chai AI, ChaiNote, ChaiDraw, ChaiWord, ChaiExcel, ChaiSlides, ChaiPodcast Studio, ChaiMeasure AR, Bill Studio, games, and more — are not commercialized or sold as standalone products. They are included free with the platform.

We charge for platform resource utilization (hosting, storage, realtime collaboration, and infrastructure) through shop subscriptions or optional add-ons where applicable. Using miniapps themselves does not incur a separate product fee.

Our aim is to keep digital services affordable for chai shops, customers, and suppliers across India — free utilities where we can, fair pricing for the resources that power them.

Open-source JavaScript authors we thank

Several miniapps and tools are built on community-maintained JavaScript libraries. We are grateful to their authors and contributors.

Mozilla PDF.js — PDF rendering and parsing in the browser
pdf-lib — PDF split, merge, and document editing
jsPDF — PDF generation across the platform
heic2any — HEIC / HEIF to JPG conversion in the browser
ffmpeg.wasm — Video compression in the browser (WebAssembly)

Thank you to every maintainer whose work helps us ship accessible, browser-based tools.
