The Private Alternative
to CloudConvert
Stop uploading sensitive files to remote servers. FluxConvert processes everything locally in your browser — faster, safer, and completely free.
Cloud converters have a trust problem
Every time you upload a file to CloudConvert, you're trusting a third party with your data.
Upload Required
Your files are transmitted over the internet and temporarily stored on remote servers you don't control.
Server Processing
Third-party infrastructure handles your data. Server breaches, employee access, or policy changes can expose your files.
Limits & Costs
Free tiers cap at 25 conversions/day and 100MB files. Need more? Pay $9–15/month for credits.

Why FluxConvert is the Best CloudConvert Alternative in 2025

Unlike traditional cloud-based converters, FluxConvert processes everything directly in your web browser using modern WebAssembly technology — meaning your sensitive documents, photos, and media files never leave your device.
