Rotate ICO FAQ
Can I rotate by an arbitrary angle, not just 90 degrees?
+
Yes, though the two are different operations underneath. A multiple of 90 degrees rearranges existing data; any other angle has to rebuild the grid and fill the corners, so it costs a resample and usually wants a background colour choosing.
Why does my file look correct on my phone but sideways elsewhere?
+
Because the orientation is stored as an EXIF flag rather than in the pixels, and not every viewer honours it. Rotating here normalises the two — the pixels and the flag end up agreeing, so the file looks the same everywhere.
Can I rotate a whole batch in one go?
+
Yes. The same rotation is applied across every file you upload, which is the practical fix for a folder of scans or camera output that all came in the wrong way round.
How does Rotate ICO turn the file?
+
Concretely, each bitmap in the stack is rotated and the entries stay square, which is the only orientation an icon container permits. Quarter turns and half turns are the common case and take the cheapest path available for the format.
Can I run Rotate 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.
Does Rotate ICO cost anything?
+
No. Rotate 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 Rotate 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.
Will Rotate 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.
Does Rotate ICO belong on a site about a photo format?
+
JPEG.to is built around the format that carries nearly every photograph in existence — thirty years old, opened by literally everything, and still the right default for a photographic image. The jobs people bring here are the ones a photograph collects over its life — too big to email, wrong dimensions for a form, wrong way up out of a phone. Rotate ICO runs on the same upload and the same account as the conversions because that is where those jobs land.
What is the sensible next step after Rotate ICO?
+
The converter on this site moves images to and from JPEG, PNG, WebP and HEIC, which is where the trade between file size and one more generation of loss gets settled. Deciding the format last rather than first is the whole point: every extra save of a photographic image is another generation, and the fewer of them you spend, the more of the picture survives.
Is this the same engine as the other converter sites?
+
Yes — the same libraries, the same workers, the same caps. The difference is which advice is on the page, and here that advice is built on one property of the format the site is named after: the .jpeg and .jpg extensions are the same bitstream, so nothing here behaves differently from a .jpg — only the filename changes.
Is anything kept, and do I need to sign in?
+
Nothing is kept and no account is needed. Uploads are removed from the workers shortly after the job finishes; nothing is looked at, listed or indexed. An account buys history and larger batches, not access.
