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 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.
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.
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.
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.
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.
Why does a PDF site host Crop ICO?
+
PDF.to exists because PDF is where documents go to be shared and the worst place to keep them while they are still being worked on, so nearly every job here is about getting something into or out of that state deliberately. A document rarely arrives in the state it needs to leave in: it is too big, in the wrong order, locked, or a scan with no text in it. Crop ICO sits on the same upload and the same account as the conversions because those jobs turn up together.
What should I do with the result once Crop ICO is finished?
+
The converter on this site moves documents between PDF, Word, images, plain text and eBook formats in either direction, so whatever comes out of a tool here has somewhere to go next without a second upload. Running that after Crop ICO rather than before keeps the document structure intact through the step that is most likely to flatten it.
Is Crop ICO here the same tool the sibling sites run?
+
The engines are shared — the same document toolchain, the same workers, the same limits. What a PDF site adds is a view on when a file should stay a document and when it genuinely wants to become something else, which is the decision most tools quietly make for you. It also starts from one fact about the format this site is named after: a PDF is an object graph, not a page image, so text stays selectable and vectors stay sharp no matter what happens to the raster content inside it.
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 read and nothing is indexed. Free accounts exist for history and batch size, not for access.
