Yes, every conversion tool is completely free — no sign-up, no credit card, no hidden fees.
No. Most conversions happen directly in your browser. In the rare cases where a file has to pass through a server, it's permanently deleted immediately after processing — never stored.
Honestly, Convertio and ezgif are established, proven tools — we're not claiming to "beat" them. What's different here is two things: first, you don't need to know the format name — you can type a normal sentence like "shrink this video for WhatsApp" and AI picks the right settings for you. Second, we're not just a file converter — QR code creation/repair and PDF compression live under the same roof, so you don't need to jump between separate sites.
A small AI model reads what you typed and figures out the format and settings you mean (e.g. turning "for WhatsApp" into concrete settings like "MP4, under 16MB, 720p"). We ask you to confirm before anything happens, then the actual conversion runs in your browser.
We wanted to bring common file-related problems under one roof. QR Doctor doesn't just generate codes — it also diagnoses and repairs QR codes that won't scan, something we haven't seen on any other site.
For browser-based conversions, the practical limit depends on your device's memory — most users are fine up to a few hundred megabytes. Very large files may process more slowly.
