Split PDF by Bookmark — frequently asked questions

My PDF has no bookmarks — what happens?+

The tool tells you and you should use Split PDF with page ranges instead.

What about nested bookmarks?+

Only the top-level bookmarks are used as split points.

Adakah anda memuat naik fail saya ke pelayan?+

Tidak — setiap alat di sini memproses fail anda sepenuhnya pada peranti anda, dan tiada apa dimuat naik ke pelayan. Satu-satunya pengecualian ialah alat AI, yang menghantar teks yang diekstrak (bukan fail) ke Claude untuk melakukan kerjanya.

Adakah terdapat had saiz fail?+

Kami tidak mengenakan had buatan, tetapi kerana pemprosesan berlaku dalam pelayar anda, fail yang sangat besar (500+ MB atau 1,000+ muka surat) dihadkan oleh memori peranti anda, bukan oleh kami.
