Why ConvertPivot?
Most online file converters work the same way: you upload your file to their server, they convert it, you download the result. The trade-off most users don't think about: your file lives on their server, even if briefly.
ConvertPivot takes a fundamentally different approach. Every conversion runs locally in your browser using WebAssembly — the same technology that gives desktop-class performance on the web. Your files never leave your device. There is no server, no cloud storage, no account, and no data collection.
This architecture is verifiable: open your browser's Developer Tools ? Network tab during any conversion and confirm that zero file data is transmitted. Your sensitive bank statements, contact databases, and private notebooks stay private.
Complete Privacy
Because everything runs client-side, your files never cross a network boundary. Financial documents, medical records, and legal files stay on your machine — through every step, until you download the result. No third party ever sees your data.
No Limits, No Gates
There are no daily conversion caps, no file size limits, no watermarks, and no "upgrade to unlock" dialogs. The free tier handles files as large as your browser memory permits. Premium tiers exist only to support optional cloud restore features — never to degrade the free experience.
Works Everywhere
All 90+ tools work on desktop and mobile browsers. You can convert files on a Chromebook, a locked-down work laptop, an iPad, or an Android phone — no installation required.

Frequently Asked Questions

No. Every conversion runs locally in your browser using WebAssembly and JavaScript. Your files are never uploaded to any server. You can verify this by opening your browser's Network tab during a conversion — zero file data is transmitted.
ConvertPivot supports 90+ conversion types across financial files (OFX, QFX, QBO), contacts (VCF, CSV, XLSX), notebooks (IPYNB), GPS data (GPX, KML, FIT), images (HEIC, AVIF, WebP, SVG), CSS tools (color spaces, logical properties, view transitions), and developer tools (binary, hex, timestamp).
Your practical limit is your browser's available memory, typically 1-4 GB. Since files never leave your device, there are no server-imposed caps.
Yes. All tools work on mobile browsers including Chrome, Safari, and Firefox on both Android and iOS. Tap the drop zone to select files from your device.
No account, email, or signup is required. Just open any tool, drop your file, and convert. No tracking, no data collection.
Most online converters upload your files to a server for processing. ConvertPivot runs every conversion locally in your browser using WebAssembly. Your files never leave your device, ensuring complete privacy. There are also no daily limits, no queues, and no upgrade gates.
Files are processed entirely in your browser's memory. Once you close the tab or download the result, everything is discarded. No copy exists on any server because your data never left your device.
