Convert files the way they were meant to be.
Every other converter sends your files to a stranger's server. LocalTools runs entirely in your browser — your files never leave your device. Same result. Zero exposure.

What can LocalTools convert?
Supporting the formats that matter - with more added regularly.
3D Formats
Document Formats
* Spreadsheet/Word to PDF is visual export only. Formulas and macros are flattened.
Image Formats
SVG, GIF, TIFF, HEIC, PSD, AI, RAW, and PDF are input-only. AVIF output requires a modern browser.
We can't see your files. Not because we promised. Because it's impossible.
Most file converters are file upload services in disguise. Your document goes to a server, gets processed, and comes back. That means someone else's computer touched your files.
LocalTools is different. The conversion engine runs entirely inside your browser using WebGPU. There is no server step. There is no upload. There is nothing we could intercept even if we wanted to.
