FLV to ICO Converter

FLV is Adobe's legacy Flash Video container — a clip is hundreds of frames of motion over time. ICO is the Microsoft Windows icon format — a single tiny still image, often only 16 to 48 pixels square. Because the two are so different, this converter does one thing: it grabs a single frame from your FLV (the very first frame by default, or any moment you specify) and shrinks that one picture down to an icon. All motion and audio are discarded. It is the right tool when you want to turn a logo sting or title card from an old Flash-era video into a favicon or app icon.

How to Convert FLV to ICO

  1. Upload Your FLV File: Drag and drop your .flv onto the page or click "+ Add Files". You can queue several clips and convert them with the same settings; each video produces its own ICO.
  2. Pick the Frame: Open the options. Under Frame Selection, choose Specific Frame and enter the Time (seconds) of the moment you want — the default is 0, the very first frame. Decimals work, so 2.100 means 2 seconds and 100 milliseconds in. Or pick Multiple Screenshots to capture frames at a set rate and keep the best one.
  3. Set the Icon Size: Under Image resolution → Preset, choose the square icon size — 16, 24, 32, 48, 64, 128, 180, 192, or 256 pixels. 256 is the largest the ICO format holds.
  4. Convert and Download: Click Convert and download your .ico. No sign-up, no watermark.

Why the Picture Loses Detail

An FLV frame is often already low-resolution SD web video — Flash clips were commonly 320×240 or 480×360. Shrinking even a 480p frame down to a 16×16 or 32×32 icon throws away almost all of the original picture: a 480×360 frame is about 173,000 pixels, while a 32 px favicon is only about 1,000. Detail-heavy frames — small text, busy backgrounds, faces in a crowd — become unrecognizable at icon size. That is normal for an icon and not a flaw in the conversion; the fix is to pick a frame with a single bold, high-contrast subject. If your artwork is already a still logo rather than a video, PNG to ICO keeps your full source resolution up to the 256 px limit and is the cleaner path for a favicon.

Frequently Asked Questions

Which frame from the FLV does it capture?

Whichever one you choose. Under Frame Selection, pick Specific Frame and enter the timestamp in Time (seconds) — the default is 0, the very first frame of the clip. Decimals are supported, so 3.5 grabs the frame three-and-a-half seconds in. If you do not know the timestamp, scrub the FLV in VLC, read the time at the bottom, and type that value. You can also pick Multiple Screenshots to capture a sequence and keep the best result.

Does converting FLV to ICO keep the video's motion or audio?

No. An ICO file is a static Windows icon — it holds one or more still images, never video or audio. This tool extracts a single frame from your FLV and writes it as an icon; everything else in the clip, including the soundtrack and all other frames, is discarded. If you want motion, convert to an animated GIF instead.

Can I still open an FLV file in 2026?

Not in a browser. Adobe ended Flash Player support on December 31, 2020, and every major browser removed the Flash plugin, so an FLV will not play on a web page anymore. It still opens in desktop players that bundle their own decoders — VLC, MPV, MPC-HC, and PotPlayer all read FLV. This converter reads the file on our servers, so you do not need any player installed to extract a frame from it.

What is the largest icon I can get from an FLV frame?

256 × 256 pixels. That is the maximum dimension the ICO format supports, no matter what the source video resolution is. Because most FLV clips are SD (320×240 to 640×480), the frame is usually being downscaled to icon size rather than upscaled — but it will never exceed 256 px. For a website favicon, Microsoft's recommended minimum set is 16, 24, 32, 48, and 256 px.

Why does my icon look worse than the video frame?

Because it is far smaller. In our testing, a typical SD Flash-era frame shrunk to 16–32 px loses almost all fine detail, so the clearest icons come from frames with one bold subject and high contrast. A 480×360 frame is about 173,000 pixels; a 32 px favicon is only around 1,000 — almost the entire picture is thrown away in the downscale, which is expected for an icon. Avoid frames mid-transition or packed with small text.

Should I build a favicon from a video frame or a still image?

If you have the logo as a still image, a static source is cleaner — PNG to ICO keeps your full resolution up to 256 px with no frame-grab guesswork. Grab a frame from the FLV only when the artwork exists nowhere except inside the video (a logo sting or title card from an old Flash reel). For a full-resolution still rather than an icon, use FLV to PNG.

How long do you keep my uploaded FLV file?

Your file is uploaded over an encrypted connection, processed on our servers, and then deleted automatically a few hours after conversion — never shared, never made public, and there is no sign-up or watermark.
