No file limits · Nothing uploaded · 100% free

Image conversion that never uploads your files.

Convert HEIC, WebP, JPG and PNG in batches — decoded and encoded on your own device with WebAssembly. Free, unlimited, and truly private.

Free online image converters

Every tool works the same way: drop files, convert locally, download. Nothing is ever uploaded.

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.
