Question 1

Are my PDFs uploaded to your server?

Accepted Answer

No. Your PDF is read, parsed and split entirely inside your browser using pdf-lib and pdf.js. Nothing is uploaded, logged or stored.

Question 2

Can I split a password-protected PDF?

Accepted Answer

Encrypted PDFs cannot be split directly. Unlock the file first, then load it back into the Split Studio.

Question 3

Can I extract only certain pages?

Accepted Answer

Yes. Switch to the Extract selected mode, click the pages you want in the thumbnail grid (Shift-click to select a range), then press Split PDF.

Question 4

Can I split every page into its own PDF?

Accepted Answer

Yes. Choose the Every page mode. Each page becomes an individual PDF and everything is bundled into a single ZIP for download.

Question 5

Can I split large PDFs?

Accepted Answer

Yes. Thumbnails are lazy-rendered so 500+ page PDFs stay responsive. Very large files depend on your device's memory.

Question 6

Does it work on my phone?

Accepted Answer

Yes. The Split Studio is fully responsive with touch-friendly page selection on Android, iPhone and iPad.
