About this tool
Split PDF when one file holds pieces that should travel separately: a signed page, an appendix, or one invoice from a statement. You name the pages or a range. The download contains those pages and not the rest. Splitting does not compress artwork and does not OCR a scan. A confidential page you leave out never sits on someone else’s disk as part of processing. If you need a new order rather than a cut, use Organize PDF.
Split PDF stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
- No upload: only the pages you keep are written, and the source never leaves this device.
- Speed: the file does not travel to a server and back, so the wait is only the work itself.
- Quality: the original is kept when the new file would be worse or is not actually smaller.
FAQ
Does “Split PDF” upload my file?
Split PDF reads the file in this tab. There is no upload step and no account.
What will “Split PDF” actually change?
The new file contains the ranges you asked for. Other pages are not in the download.
When is “Split PDF” the wrong job?
Splitting does not hide a sentence on a page you keep. It only omits pages you did not ask for.
How do I check the result of “Split PDF”?
Count the pages in the download against the range you typed. The file name follows that range.
Can I run “Split PDF” with Wi-Fi off?
Load this page, then turn Wi-Fi off and run Split PDF again. A finished result is the proof that the file was not sent anywhere.
