Question 1

Does Fluxed work without an internet connection?

Accepted Answer

Once you've loaded the app at least once, all conversions work fully offline - image, audio, PDF, ICO, and Word. The Service Worker caches the entire app locally, so it even loads without a connection.

AIFF and WMA audio inputs are the one exception - they load an extra decoder on first use, which needs a brief download. After that they're cached and work offline too.

Question 2

What happens if I lose my internet connection mid-conversion?

Accepted Answer

Nothing breaks. Conversions run entirely in your browser using your device's CPU - there's no server involved, so the network state doesn't matter once the app is loaded.

Question 3

How is offline mode possible?

Accepted Answer

Fluxed is a Progressive Web App with a Service Worker that caches the entire app and its assets locally. All conversion logic runs in-browser via Web Workers and native browser APIs - nothing leaves your device.

Question 4

Do you collect my data?

Accepted Answer

Nothing is collected. Fluxed runs fully client-side and has no analytics, tracking, cookies, login, or ads. Your files never leave your device.

Question 5

Can I use Fluxed on public WiFi?

Accepted Answer

Completely fine. All processing happens locally and nothing is sent over the network, so public WiFi doesn't change anything about how Fluxed handles your files.

Question 6

What image formats do you support?

Accepted Answer

Input: JPEG, PNG, WebP, GIF, SVG, AVIF, TIFF, BMP, HEIC. Output: JPEG, PNG, WebP, AVIF. Background removal is also supported. It uses a local ML model (~170MB) that is downloaded on first use and cached by the Service Worker - after that it works fully offline. The first run takes a moment while the model loads.

Question 7

What audio formats are supported?

Accepted Answer

Supported: MP3, MP2, WAV, OGG, AAC, FLAC, OPUS, M4A, M4R, AIFF, WMA, AC3, AMR, DTS, Speex (SPX), CAF, W64, WavPack (WV), VOC, TTA, and RealAudio (RA). FFmpeg loads on first conversion, then stays cached for offline use. You can strip ID3 metadata during any conversion.

Question 8

Does this work on mobile?

Accepted Answer

Works fine on mobile. All conversions run locally in the browser, so performance and offline support are identical to desktop. To install as a PWA on Android, tap the browser menu and select "Add to Home Screen". On iOS Safari, use the Share sheet and tap "Add to Home Screen".

Question 9

What browsers are supported?

Accepted Answer

Any modern browser - Chrome, Firefox, Safari, Edge. Keep it updated; features like AVIF encoding depend on browser-level codec support that improves with newer versions.
