1Upload the images that came out the wrong way round.
2Pick a quarter turn or a half turn, or type an arbitrary angle and choose a colour for the corners it will expose.
3Apply the rotation; the pixels and the orientation flag are reconciled so every viewer agrees on which way is up.

Rotate Image FAQ
How does Rotate Image turn the file?
+
Concretely, right-angle rotations take the lossless path wherever the source format allows it, and only arbitrary angles resample, so a mixed batch is not needlessly re-encoded. Quarter turns and half turns are the common case and take the cheapest path available for the format.
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.
Does the format decide whether rotation is lossless?
+
It does. this format is read and written by the same streaming pipeline as everything else we support. That property is exactly what determines whether a quarter turn is free or costs a re-encode.
Anything specific to Image I should know?
+
Yes — the pipeline reads the real format from the file header rather than the extension, so a mislabelled upload still works. It is the kind of thing that explains why a file looks right in one application and wrong in another.
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.
Which image formats does Rotate Image accept?
+
All of the common ones — JPG, JPEG, PNG, WebP, GIF, BMP, TIFF, SVG, ICO, PSD, JFIF and HEIC. You can mix formats freely in one batch; each file is identified from its header and routed to the right decoder.
Is there a file size limit on Rotate Image?
+
Yes: free accounts process images up to 25 MB each regardless of which image format you brought; ImageMagick, libjpeg-turbo, libpng and libwebp do the actual work. The cap is per file, so a batch of twenty 5 MB photos is fine even though the total is well over the limit.
Will Rotate Image lower the quality of my images?
+
That depends on what you brought. A lossless source (PNG, BMP, TIFF) round-trips exactly; a lossy one (JPG, WebP, GIF) is already the product of one quantisation pass and only re-encodes if the operation genuinely requires it.
Can I run Rotate Image on several images at once?
+
Yes, and mixing formats in the batch is fine — settings are applied per file with the right decoder for each. Free accounts run one file at a time; a pass removes that.
What happens to metadata and transparency?
+
EXIF and the ICC colour profile are carried across wherever the target format supports them, and an alpha channel survives into any format that has one. Transparency is only flattened when the destination format has no way to represent it.
Does Rotate Image cost anything?
+
No. Rotate Image is free without an account and adds no watermark. Uploads are deleted from the workers shortly after the job completes.
