Convert Files Without Uploading Them — Free, Local, Unlimited
Convert Files Without Uploading Them — Free, Local, UnlimitedYour PDFs, images, and videos never touch a server. Everything runs in your browser.
Most online converters upload your files to their servers, convert them there, and “promise” to delete them later.
Local converters skip the upload entirely. The conversion runs inside your browser using WebAssembly — your files never leave your device. No upload wait, no bandwidth wasted, no privacy policy to hope they follow. Works offline too.*

⚠️ Why This Matters — Cloud Converters and Your Files
| Cloud Converter Problem | Why It’s A Problem |
|---|---|
| Files hit third-party servers | You’re trusting a stranger’s privacy policy with your tax docs, contracts, and photos |
| Conversion limits | iLovePDF, Convertio, etc. cap free conversions — then paywall you |
| Data retention | “Deleted after 24 hours” — you have no way to verify that |
| Interception risk | Files travel over the internet to reach their servers — even with SSL, the server sees everything |
| Work/legal compliance | Many companies prohibit uploading internal documents to third-party cloud services |
Local conversion eliminates all of these. If it runs in your browser, nobody else sees it.
