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
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.
What is the most common mistake when cropping ICO icons?
+
Cropping before resizing. Crop first from the full-resolution original, then resize the result — doing it the other way round means the region you keep has already lost detail it did not need to lose.
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 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.
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.
Why does a PNG site host Crop ICO?
+
PNG.to is built around the format you use when you cannot afford to lose a pixel: lossless, alpha-capable, and the correct answer for screenshots, logos, line art and anything with hard edges. Image work is rarely one step: people arrive to change a format and leave needing the picture a different size, a different weight or a different shape. Running Crop ICO on the same upload pipeline, the same size caps and the same account is the whole reason it is here rather than on a fourth tab.
What should I do with the result once Crop ICO is finished?
+
The converter on this site moves images to and from PNG, JPG, WebP, GIF and SVG — which is the step where the decision about transparency actually gets made. That is the step most people actually came for, and doing it after Crop ICO rather than before it means the conversion works from the file you finally settled on.
Is Crop ICO here the same tool the sibling sites run?
+
The engines are shared — the same libraries, the same workers, the same limits. What differs is the advice, and the advice here starts from one fact about the format this site is named after: there is no quality slider to get wrong — a PNG round-trips bit-exactly, so the only thing edits cost you is file size. A PNG site is opinionated about where PNG is the right destination and where it is not, and that judgement is worth more than the button.
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, and nothing you process is indexed, listed or used for anything else. Free accounts exist for history and batch size, not for access.
