1Upload the TIFF images that came out the wrong way round.
2Pick a turn of 90, 180 or 270 degrees.
3Apply the rotation; the pixels and the orientation flag are reconciled so every viewer agrees on which way is up.

Rotate TIFF FAQ
Can I rotate a whole batch in one go?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
How does Rotate TIFF turn the file?
+
Concretely, the pixel array is transposed and written back exactly, so a rotation of a lossless image is free in fidelity terms at any right angle and costs only resampling at an arbitrary one. Quarter turns and half turns are the common case and take the cheapest path available for the format.
Anything specific to TIFF I should know?
+
Yes — a single TIFF can hold several pages and 16-bit-per-channel data, so a tool has to decide whether to act on page one or on all of them. It is the kind of thing that explains why a file looks right in one application and wrong in another.
Is there a file size limit on Rotate TIFF?
+
Yes: free accounts process images up to 5 MB each; lossless sources hit that ceiling sooner than photographs do, because nothing has been thrown away yet. If you are over it, converting to PNG first is often enough on its own — a BMP is routinely ten to twenty times the size of the identical image as PNG.
Can I run Rotate TIFF on several TIFF images at once?
+
Yes — upload the set and they process in parallel under one set of settings. Lossless files are larger, so a big batch is bound by your upload speed rather than by the processing itself.
Why does a EPUB site host Rotate TIFF?
+
EPUB.to is built around the open eBook format — XHTML in a zip, reflowable by design, and readable on hardware nobody has thought about the layout for. A book is a zip full of markup, images and fonts, so almost every job people bring to an eBook site is really a job on one of those things. Rotate TIFF runs on the same upload and the same account as the conversions because that is where it is needed.
What should I do with the result once Rotate TIFF is finished?
+
The converter on this site moves books between EPUB, MOBI, AZW3, PDF and DOCX, so a title ends up on whatever hardware is actually going to read it. Doing that after Rotate TIFF means the conversion is made from the version you settled on, not from the one you were still fixing.
Is Rotate TIFF here the same tool the sibling sites run?
+
The engines are shared — the same toolchain, the same workers, the same limits. What a EPUB site adds is a view on reflow: which of these operations a reflowable book genuinely supports, and which ones only make sense on the fixed-layout media inside it. It also starts from one fact about the format this site is named after: the book is a zip of XHTML with a manifest, so the text costs almost nothing and every decision that matters is about the embedded images and font subsets.
Do I need an account, and does anything get kept?
+
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
