Rotate PDF
Turn pages that came out of a scanner sideways. The rotation is written into the file, so it stays turned wherever the document is opened — not just in the viewer you happen to be using.

Rotation adds to what is already there. A page that a scanner already marked as 90° turned, rotated another 90°, ends up at 180 — which is what you want, and is why this page reads each page's existing rotation rather than assuming every page starts upright.
Turning a page in the viewer is not the same as rotating it
Most PDF readers have a rotate button, and for most of them it changes only what you are looking at. Close the file and it is sideways again; send it to someone and it arrives sideways; print it and it prints sideways. That button is a view setting, not an edit.
A PDF page carries its own /Rotate value — 0, 90, 180 or 270 — and that is what this page changes. The result is a new file in which the pages are genuinely turned, for every reader and every printer.
Why only four angles
Because those are the only ones the format allows. /Rotatemust be a multiple of 90. Straightening a scan that is off by three degrees is a different operation entirely — it re-renders the page as an image and loses the text — and it is not what this does.
Existing rotation is read, not assumed
Scanners commonly write a rotation of their own. If this page assumed every page started at 0, a document that was already marked 90 would come back at 90 instead of 180, and only some of the pages would look wrong — the most confusing possible result. Each page's current value is read and the turn is added to it.

Common questions
- Is this Rotate PDF pages page free to use?
- Yes. Every Kaamko tool is free, with no sign-up, no account and no usage limit. They are published by Imperial College of Engineering, a Tribhuvan University-affiliated engineering college in Tathali, Bhaktapur, and are not funded by advertising.
- Does what I type get sent anywhere?
- No. This tool runs entirely in your browser: the calculation happens on your own device, nothing you type is uploaded, and nothing is stored after you close the page.
- Where do the figures come from?
- Each tool names its source on the page, along with the date that source was read. Where a rate or a slab is provisional — announced in a budget speech but not yet gazetted, for instance — the page says so rather than presenting it as settled.
- Who maintains these tools?
- Imperial College of Engineering, formerly Janakpur Engineering College, in Tathali, Bhaktapur, Nepal. Corrections are welcome by phone on 01-5091616 or through the contact page, and a figure reported as wrong is checked against its published source rather than adjusted on request.
Last checked by Imperial College of Engineering. Rates, slabs and formulas are re-checked against their published source on this date.
