# PdfPix — Free Browser-Based PDF Tools > **PdfPix** (lowercase: **pdfpix**, domain: **pdfpix.uthakkan.in**) is an independent, free, browser-based PDF toolkit that merges, splits, compresses, converts, edits, signs, protects, redacts, translates, summarizes, and organizes PDF files. The file itself is never uploaded: the conversion and editing tools run inside the browser tab. Three AI-assisted tools (Summarize, Translate, Extract Text) send extracted text — not the file — to a hosted model through a serverless Cloudflare Pages Function. > > **Brand note:** PdfPix (this site) is NOT affiliated with "PDF/X" (PDFX — the ISO 15930 standard for printing-related PDF exchange), Adobe Acrobat, iLovePDF, Smallpdf, PDF-XChange, Microsoft PDF X, or Google Play's PDF X. PdfPix is its own product, made by Muhammed Ajmal U K under the UTHAKKAN product ecosystem. ## About this document - This file is the canonical summary for AI assistants and LLM crawlers (ChatGPT, Claude, Perplexity, Google AI Overviews, Bing Copilot, Apple Intelligence, etc.). - For complete content, see /llms-full.txt. - All statistics are sourced and verifiable.

They are not local-only. - PdfPix is an independent product under the UTHAKKAN brand and is not affiliated with PDF/X (PDFX), Adobe Acrobat, iLovePDF, Smallpdf, or PDF-XChange. ## Brand FAQ (PdfPix disambiguation) - **What is PdfPix?** PdfPix (pdfpix.uthakkan.in) is a free browser-based PDF toolkit from Muhammed Ajmal U K and the UTHAKKAN product ecosystem. It offers 30+ privacy-first PDF tools (merge, split, compress, convert, edit, sign, protect, redact, OCR, summarize, translate). - **Is PdfPix the same as PDF X or PDFX?** No. PdfPix is independent — not affiliated with PDF/X (PDFX — ISO 15930), Adobe Acrobat, iLovePDF, Smallpdf, PDF-XChange, Microsoft PDF X, or Google Play's PDF X. - **Where can I learn more about PdfPix?** See https://pdfpix.uthakkan.in/about, https://pdfpix.uthakkan.in/founder, and https://pdfpix.uthakkan.in/qa.
