FLV to AVI Conversion FAQ
Is the FLV to AVI converter free?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
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.
How big an FLV file can I convert to AVI?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Can I convert many FLV files to AVI at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
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 on our own servers and are never viewed or shared. Uploads and results are deleted automatically about 24 hours after conversion. See /privacy/ for the full policy.
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?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
