Why ConvertYard exists

Every time you upload a file to a random conversion website, you're trusting a stranger with your data. A contract, a medical record, a family photo, source code — it leaves your device and lands on an unknown server. Most sites are fine. Some aren't. None of them should need to see your file in the first place.

The technology to do this better has existed for years. WebAssembly lets browsers run native code — the same C++ libraries that power professional desktop software — at near-native speed. libvips handles image conversion. ffmpeg handles video. pdf-lib handles PDFs. All of them compile to WASM and run inside a browser tab without any network round-trip.

ConvertYard is the realization of that: every tool processes files locally in your browser. Your CPU does the work. Nothing uploads. Not for convenience, not "securely" — simply not at all. You can verify this yourself by watching your network tab during a conversion.

The second thing we got tired of: conversion tools that only handle one file at a time. If you have 200 product images to convert, or 50 PDFs to merge, you don't want to babysit a single-file form for an hour. ConvertYard is batch-first. Every tool accepts as many files as you can drag in.

What we're building

A network of local-first batch conversion tools covering images, PDFs, video, audio, developer utilities, and web tools. The goal is to replace every "upload to some random website" workflow with a version that never needs to leave your browser.

Tools are free, supported by minimal display ads that appear only below tool content — never inside the conversion flow. There's no signup wall, no watermark, no artificial file limit designed to push you to a paid plan.
