Supports: ICO
ICO is the Windows icon container — a small still image, usually somewhere between 16×16 and 256×256 pixels. MOV is Apple's QuickTime video container. Converting ICO to MOV wraps that single icon image into a short, silent video clip: the picture is held on screen as one motionless frame for a duration you choose. There is no animation and no audio — it is a still slate, not a moving image. People reach for this to drop a logo or icon onto a video timeline that only accepts video clips, to make a placeholder/"bumper" slate, or to feed an icon into a tool that expects a .mov input.
| Property | Value |
|---|---|
| Full name | Windows Icon (ICO) |
| Developer | Microsoft |
| First shipped | Icons date to Windows 1.0 (1985); the modern multi-image ICO evolved with later Windows releases |
| Typical sizes | 16×16, 32×32, 48×48, up to 256×256 pixels |
| Color depth | 1-bit monochrome up to 32-bit (16.7M colors + 8-bit alpha transparency) |
| Multiple images per file | Yes — one ICO can store several sizes/depths; converters use the largest available |
| PNG-compressed entries | Supported since Windows Vista (recommended for 256×256 entries) |
| Best for | Application, favicon, and shortcut icons in Windows |

| Full name | QuickTime File Format (MOV) |
| Developer | Apple |
| Released | 1991 (specification published publicly in 2001) |
| Extensions | .mov, .qt |
| Type | Multimedia container holding video, audio, and text tracks |
| Common video codecs | H.264, HEVC (H.265), MJPEG, ProRes in pro workflows |
| Relationship to MP4 | Apple's 2001 QuickTime spec was the basis ISO used for the MPEG-4 (MP4) container, so the two are closely related |
| Best for | Editing in Final Cut Pro / iMovie and other QuickTime-native workflows |
.ico onto the page or click "+ Add Files" to pick it from your device.No. The conversion holds the ICO as a single still frame for the duration you set — there is no animation, transition, or panning, and the clip carries no audio track. If you need movement or music, add the still MOV to a video editor and animate or score it there.
Because ICO files are tiny by design — often 16×16 to 256×256 pixels. A 256×256 icon is far below even 720p (1280×720), so at native size the clip is a small square. Choosing a larger Video resolution preset enlarges the frame, but it can only scale up the existing pixels; it cannot add detail, so upscaled icon edges look blocky. For the sharpest result, start from the largest size stored in the ICO.
You control this with the Duration option. The default is 5 seconds, and you can pick shorter or longer holds (down to about a second and up to roughly ten seconds) depending on how long you want the icon slate to stay on screen.
An ICO file can pack multiple resolutions in a single file. The converter reads the largest image available so the output is as sharp as the source allows. If your icon tops out at 48×48, the video starts from 48×48 before any upscaling you request.
Yes. The Background Color option fills any space around the icon when the frame's aspect ratio doesn't match the square icon (for example, fitting a square icon into a 16:9 frame). Black is the default; you can switch it to white or another preset color to match your project.
MOV is ideal if you'll edit in Final Cut Pro, iMovie, or another QuickTime-native tool. For broad playback on the web, social platforms, and Android, MP4 is the more universally accepted container. The two are closely related — Apple's QuickTime spec was the basis for MP4 — so you can convert the result later with MOV to MP4 if a platform rejects .mov.
Often, yes. If you only need the icon as a picture rather than a video clip, converting to a normal image format gives a cleaner, smaller file. Use ICO to PNG to keep transparency, and reach for the video conversion only when a workflow specifically requires a .mov.
Your ICO is uploaded over an encrypted connection, processed on our servers, and the files are deleted automatically a few hours after the conversion. No account is required, and there are no watermarks added to the output. In our testing, a single 256×256 icon held for 5 seconds produced a small MOV well under a megabyte.
