Why local conversion beats "free" upload sites
Most online converters upload your photos to their servers, then cap usage to sell a subscription. FileWift is built the opposite way.
Nothing uploaded
Decoding and encoding run on your device via WebAssembly. Disconnect your Wi-Fi and convert anyway — that's the proof.
No limits
Batch-convert your entire Camera Roll if you want. No file count caps, no size caps, no queue, no account.
100% free
No subscriptions, no watermarks, no premium tier holding basic features hostage. Your CPU does the work, so it costs us nothing.
