Can it find the sideways pages by itself?

No. It does not inspect the pages to guess which way up they should be - you look at the grid and pick. For a scan where every second page is upside down that means clicking those pages or typing their numbers, since there is no odd-or-even shortcut on this particular tool.

Can I straighten a scan that is crooked by a few degrees?

No. A PDF page's rotation is only allowed to be 0, 90, 180 or 270, and this tool sticks to that. Straightening a photograph by three degrees means redrawing the page as a picture, which would soften the text and the barcode, so it is deliberately not offered here.

Does rotating cost quality or make the file bigger?

Neither. The instruction that draws the page is not touched; only the page's rotation property changes, which is a couple of bytes. A rotated 12 MB scan comes out at roughly 12 MB, with the text exactly as sharp as it was.

Will a rotated shipping label still scan?

Yes. The barcode is the same vector artwork it was before, just displayed a quarter turn round, and a scanner reads it off the printed paper. In practice rotating first makes scanning more reliable, because the label comes out of the printer the way the packer expects to hold it.

Is the file uploaded to be rotated?

No. It is read, rewritten and downloaded by this browser tab on your own machine, so the addresses printed on those labels stay with you. There is no server copy of the file at any point.

Rotate the pages of a PDF

Sideways pages come from two places. A courier panel that hands out labels in landscape when your thermal printer expects portrait, and a pickup manifest photographed on a phone and saved as a PDF. Either way the printer does as it is told, and you get a sheet nobody can read without tilting their head.

Turning a page here does not redraw it. A PDF page carries its own rotation, so this sets that property and leaves the content underneath exactly as it was - same text, same images, same barcode, simply displayed the right way up. The thumbnails turn as you press the buttons, so what is on screen is what will be saved.

How it works

Add the PDF. One file at a time. Every page appears as a thumbnail so you can see which ones are lying on their side.
Choose what to turn. Every page, or only the pages you pick. In pick mode the thumbnails become clickable and the range box accepts numbers like 1-3, 7, 9-12.
Turn them. Quarter turn left, quarter turn right, or a 180 degree flip for pages that are upside down. Press again to keep going; Start again puts everything back to where it began.
Export. The button only wakes up once something has actually changed, which saves you downloading an identical copy. The file is saved as yourfile-rotated.pdf.

What it handles

Quarter turn left, quarter turn right and a 180 degree flip
All pages at once, or a selection clicked on the grid or typed as a range
Turns accumulate - pressing right twice is the same as a flip - and always land on a multiple of 90
A page that already carries a rotation is respected: a page stored at 90 and turned right ends up at 180, not back at 90
The thumbnails rotate live, so the grid is the preview
Counts in the sidebar for pages in the file, pages being turned and pages currently selected
The page content is never re-rendered, so the file that comes out is about the size of the file that went in
Export stays disabled until at least one page has been turned

Your files stay on your computer

This runs inside your browser tab. The file is read and written on your own device and is never uploaded — not the order PDF, not the customer names and addresses printed on it. There is no upload endpoint to send it to.
