FLV to AVI Conversion FAQ
How do I convert an FLV file to AVI?
+
Upload your FLV file using the picker above and the converter detects the source type and runs the FLV → AVI pipeline. The result downloads automatically when conversion completes; no account needed for one-off conversions.
Can the AVI hold more than one audio track?
+
Yes, and it is a real upgrade over FLV. AVI treats every audio stream as a first-class track, so an original-language mix, a dub and a director commentary can live in one file with the player switching between them on demand. AVI is trivially simple, which is exactly why ancient camcorders, capture cards, DVD ripping tools and Windows-era software all still emit it.
Is there any point converting between two legacy formats like FLV and AVI?
+
Only if a specific piece of equipment demands the target. Both formats come from the same pre-H.264 era, so neither conversion buys efficiency, quality or future-proofing — it buys compatibility with one particular device. If the goal is to keep the footage usable long-term, convert to a current container instead of sideways. No current browser, phone or TV can play FLV — anything still in this container has to be moved out of it to remain watchable. AVI has no native support for modern codecs, variable frame rate, soft subtitles or files over 4 GB without hacks, and its per-chunk overhead bloats the file.
Is the FLV to AVI converter free?
+
Yes — basic FLV → AVI conversion is free with no registration. Premium adds higher per-file size limits, more parallel batch workers, and removes ads.
How big an FLV file can I convert to AVI?
+
Free accounts: up to 100 MB per FLV file. Premium: typically 1 GB per file, depending on the FLV source type. Very large files are split into chunks server-side when the AVI format allows.
Will conversion change the content of my FLV?
+
Conversion preserves all information that both FLV and AVI can represent. Format-specific features that the AVI format doesn't support (e.g. vector data in raster output, formulas in plain-text output) are rasterized or stripped — see the format-specific notes on the result page.
Can I convert many FLV files to AVI at once?
+
Yes — drop multiple FLV files into the upload zone and they are queued in parallel. Premium has more parallel workers; on a 50-file batch this is the difference between minutes and seconds.
Does the FLV to AVI converter work on phones and tablets?
+
Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end.
Which browsers does the FLV to AVI converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses standard `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers work.
Are my FLV files kept private?
+
Yes — uploaded FLV files are processed in isolated workers and deleted within minutes. We never view, retain, or share content. See /privacy/ for the data-retention window.
What if the AVI download doesn't start automatically?
+
Disable any pop-up blocker, then click the download button manually. The result link stays active for 24 hours, so if your network fails mid-download, you can re-trigger from the result page without re-uploading the FLV.
How long does FLV to AVI conversion take?
+
Typically seconds for small files, a minute or two for files near the size cap. Server-side pipeline runs on dedicated workers — your laptop CPU isn't the bottleneck.
