TronoPDF

TronoPDF is a free, privacy-first online toolkit with 38+ PDF and image tools that run entirely in your browser. Unlike traditional web tools, your files are processed locally on your device using open-source libraries (pdf-lib, pdf.js, Tesseract.js) — they are not uploaded to TronoPDF servers. That makes it a safe choice for contracts, tax papers, medical records, and government documents. KEY FEATURES: • Merge, split, organize, rotate, crop PDFs and add page numbers • Compress PDF with exact-size targeting — hit 20KB, 50KB, 100KB or any limit for SSC, UPSC, IBPS banking, visa and job forms • Convert both ways: Word, Excel, PowerPoint, JPG, HTML to PDF and back • OCR scanned PDFs into searchable, selectable text (multi-language support) • Password-protect with AES-256 encryption, unlock, sign, watermark, redact • Passport photo maker with official size presets for India, US, UK, Schengen and 20+ countries • Signature resize to exact pixels and KB for online application forms • Image compressor, resizer, converter, crop and blur tools WHAT MAKES IT DIFFERENT: 1.
