1Upload your ICO icons and wait for the preview to appear.
2Drag out the region you want to keep, or lock the selection to 1:1, 4:3 or 16:9 and drag freely inside that ratio.
3Confirm the crop — the same rectangle is applied to every file you uploaded, which is how a set ends up genuinely consistent.
4Download the cropped ICO file, with everything outside the frame discarded.
Crop ICO FAQ
Can I crop several files to the same region at once?
+
Yes, and that is the case worth doing here rather than in an editor: the same rectangle is applied across the batch, which is how a set of product shots ends up genuinely consistent instead of approximately consistent.
Can I crop to a fixed aspect ratio?
+
Yes. Lock the selection to 1:1, 4:3, 16:9 or any custom ratio and drag freely inside that constraint — which is how you get a set of images that all fit the same layout slot without measuring anything.
Does my source format change how a crop behaves?
+
It can. ICO is a container that holds several square bitmaps at once (16, 32, 48, 64, 128 and 256 px) so Windows and browsers can pick the size they need. That decides whether the crop is a pure pixel operation or whether the file has to be rebuilt around it.
Anything specific to ICO worth knowing before I crop?
+
Yes — an ICO is a stack of square bitmaps, not one image, so operations apply to the stack and Windows still picks whichever size it wants. That is the sort of detail that only shows up after you have overwritten the original.
Will Crop ICO lower the quality of my ICO icons?
+
The sizes stored inside an ICO are lossless bitmaps, so the pixels themselves do not degrade. What actually decides how good an icon looks is whether the size the operating system asks for exists in the stack — a 256 px entry downscaled on the fly by Windows always looks worse than a real 32 px entry.
Can I run Crop ICO on several ICO icons at once?
+
Yes. Icon files are tiny, so a batch of them completes almost instantly; the round trip is dominated by the upload, not the processing.
Which sizes should the icon contain?
+
16, 32 and 48 pixels cover Windows Explorer and browser tabs; 256 covers large-icon view and modern shortcuts. Keeping all of them in one file costs almost nothing and stops the operating system from having to guess.
Does Crop ICO cost anything?
+
No. Crop ICO is free with no account, and the output carries no watermark — which matters more here than anywhere else, since an icon is a handful of pixels with nowhere to hide one.
Why does a WebM site host Crop ICO?
+
WEBM.to is built around the container the open web actually chose — VP9 or AV1 with Opus audio, decoded natively by every modern browser and needing no plugin, licence or player. Video is the case where extra round trips hurt most — the files are large and every upload costs real minutes. Running Crop ICO on the same pipeline as the conversions means one upload covers the whole job instead of one upload per tool.
What should I do with the result once Crop ICO is finished?
+
The converter on this site moves video between WebM, MP4, MKV, MOV and the rest, or pulls the soundtrack out entirely, without another upload. Sequencing it that way matters more for video than anywhere else: each re-encode is another generation, so the fewer of them stand between the source and the file you publish, the better it looks.
Is Crop ICO here the same tool the sibling sites run?
+
The engines are shared — the same ffmpeg build with x264, x265 and libvpx, the same workers, the same limits. What a WebM site adds is a view on containers and codecs: which combinations play everywhere, which need a re-encode and which can simply be copied across. It also starts from one fact about the format this site is named after: WebM is VP9 or AV1 with Opus audio, which browsers decode natively but which most desktop editors still transcode on import.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploaded video is deleted from the workers shortly after the job finishes, nothing is watched and nothing is indexed. Free accounts exist for history and batch size, not for access.
