What happens
4What happens, and why
Drop a PDF, choose the turn, and every page is turned by it. A scan that came out of the feeder sideways is the usual reason, and a whole document is usually sideways the same way, which is why the turn goes on all the pages at once.
Turning a page in a PDF is not an edit of the page. Every page carries a number that says how far a reader should turn it before showing it — 0, 90, 180 or 270 — and this page adds your turn to that number. The drawing underneath is untouched: no image is decoded, no text is re-laid-out, and the file comes out the size it went in. That is as exact as an edit gets, and it is why the badge says the file was not re-encoded.
Because the turn is added to what is already there, a page saved once sideways and turned back here ends up straight rather than at some third angle. Readers, printers and the preview on a phone all honour that number, so the pages stay turned wherever the file goes next.
The file never leaves your device: it is read in this tab, the number is changed here, and the result is handed straight to your downloads.
FAQ
5Does it lower the quality
No, and it cannot: nothing in the pages is decoded. A page in a PDF is a list of drawing instructions plus the fonts and images it uses, and all of that is carried over exactly as it was stored, compression and all. A scan stays the scan it was, at the size it was.
Can I turn a single page
Not on this page: the turn goes on every page. A document is nearly always sideways as a whole — a batch out of a scanner or a phone held the other way — and a per-page control would be a settings screen for the rare case. If one page is the odd one out, split the file, turn that page and join it back.
Will it print the right way up
Yes. The rotation is stored in the page itself, in the field the PDF specification defines for it, and readers and printers honour it. It is the same field a reader writes when you rotate and save there.
Does it work on a scan
Yes, and it is the best case for it. A scanned page is one large image, and turning it here does not touch that image at all — the flag changes, the photograph of the paper does not. Re-saving a scan in an image editor instead would re-compress it and cost quality.
Is the PDF uploaded
No. The browser reads the file from your disk and writes the new one on this page. There is no upload endpoint on this site, so there is nowhere for the file to go. Nothing about the document is logged either — this page does not know how many pages your file has.
