Questions
Is it free to split a PDF by size?
Yes. It is free with no sign-up and no watermark. The free plan covers up to 50 tasks a day; Pro removes every limit.
Do you upload my files?
No. The tool runs inside your browser using WebAssembly. Your file never leaves your device, and it still works with Wi-Fi turned off.
Does it work on my phone?
Yes. It works in Chrome, Safari, Edge and Firefox on Android, iPhone, Windows, Mac and Linux.
Should I compress or split?
Try Compress PDF first: one smaller file is easier for whoever receives it. Split by size when the PDF is still too big after compressing, or when the portal asks for parts.
What if one page is bigger than the limit?
Pages are never cut, so that page becomes its own part and we tell you. Compress the PDF first to bring big scanned pages down.
