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
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.
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.
How does Crop ICO select and cut the area?
+
Concretely, the crop is applied to each bitmap in the stack and the entries are re-squared afterwards, because a non-square icon entry is not a valid icon entry. You drag the region you want directly on the preview, or type exact pixel coordinates if you already know them.
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 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.
What can I upload to Crop ICO?
+
ICO files containing one or several sizes, plus ordinary PNG or JPG artwork if you are building an icon rather than editing one. Windows .ico and browser favicon files are the same format.
Is there a file size limit on Crop ICO?
+
Yes: free accounts process images up to 5 MB each, which no icon file will ever approach — a full 16-to-256-pixel stack is typically well under 200 KB. Icons are the one part of the image family where the cap is genuinely irrelevant.
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.
Why does a MP3 site host Crop ICO?
+
MP3.to is built around the format that made portable audio ordinary: universally playable, small enough to ignore, and lossy in a way that only matters if you keep re-encoding it. Audio jobs cluster: the same person who needs a format changed usually needs the file cut, levelled or made smaller in the same sitting. Putting Crop ICO behind the same upload, the same caps and the same account is what turns three tabs into one.
What should I do with the result once Crop ICO is finished?
+
The converter on this site moves audio between MP3, WAV, FLAC, M4A, OGG and Opus, so the output format is a decision you can leave until the end rather than commit to at the start. Doing that after Crop ICO rather than before means the encode happens once, on the file you actually settled on, instead of twice.
Is Crop ICO here the same tool the sibling sites run?
+
The engines are shared — the same ffmpeg build, the same workers, the same limits. What a MP3 site adds is a point of view about bitrates, about what survives an encode and about when a lossless intermediate is worth the upload time. It also starts from one fact about the format this site is named after: MP3 frames are fixed-size blocks, so a cut lands on a frame boundary and gapless playback markers do not survive a re-encode.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, nothing is listened to and nothing is indexed. Free accounts exist for history and batch size, not for access.
