About ConvertHit

ConvertHit is a growing collection of free file conversion tools — HEIC, WebP, SVG, JSON, CSV, and more. Every tool does the same job as the bigger converter sites, with one difference we care about a lot: your file never leaves your device.

Why we built it this way

Most online converters upload your file to a server, convert it there, and send it back — which means your photos, documents, and data pass through someone else's infrastructure, even if just for a moment. For a lot of files — tax documents, medical scans, client work, personal photos — that's not something people should have to think twice about.

Every ConvertHit tool runs the conversion locally in your browser using WebAssembly and native browser APIs. Nothing is uploaded, nothing is stored, and there's no account required to use any tool.

What's next

We're actively adding more converters. If there's a format conversion you wish existed without the upload step, let us know.
