Split a PDF into separate files.
This free split PDF tool breaks one PDF into individual pages, or lets you set your own page ranges — without a single page ever leaving your device.
Three steps, no waiting on a server
Altto's split tool works right in your browser tab, so there's no upload queue and no “processing your file” spinner tied to someone else's servers.
Add your PDF
Drop in the PDF you want to split. Altto reads it locally and shows you the page count.
Set your split points
Leave it blank to get one file per page, or type ranges like 1-3, 4-6 to control exactly how it divides.
Save your files
Get back one PDF, or a .zip of several, ready to share or file away.
Why this runs in your browser, not on a server
Splitting a PDF often means handling contracts, statements or scans — documents people would rather not upload to a stranger’s server just to divide into pages. Altto skips that step completely — there’s no server for it to go to.
-
Nothing is uploaded, everEvery PDF is handled by code that runs in this browser tab, because there’s no server on the other end. That also means we can’t see it, copy it or keep it.
-
No account, no email wallSplit as many PDFs as you like without signing up or handing over an email address.
-
Pages stay exactly as they wereEach page is copied from the original file, so text, images and layout come through unchanged.
documents stored on our servers. There’s no server involved at all — each split file is built once, then everything happens locally.

How many parts will I get?
1-3, 4-6, 7-10 to control exactly how it's divided, or fill in “split into groups of every” with a page count to chop it into equal-sized chunks automatically.
