Split a large PDFinto smaller files

Email is the big one. Gmail rejects attachments over 25 MB, Outlook over 20 MB. One 60-page scan of a signed contract clears both caps without trying.

Portals are stricter. Court e-filing systems, visa applications, and government forms commonly stop you at 2 to 10 MB per file. Job application sites and university admission systems often sit around 5 MB. Helpdesk and CRM tools tend to allow 10 MB.

The fix is the same everywhere: cut the document at page boundaries until each part comes in under the cap, then upload the parts one by one.

Say a 120-page mortgage packet weighs 32 MB and the lender portal takes 10 MB per file. Type 1-40, 41-80, 81-120 and you get three parts of roughly a third each. Prefer not to do the math? Switch to every N pages and the tool cuts the document into equal chunks on its own.

Each range becomes its own PDF, and the pages inside are untouched copies of the originals. This also works when only part of the document matters: pull out the exhibit a court clerk asked for, or just chapter 3, and send that instead of the whole brick.

Splitting a big file on a typical converter site means uploading the whole thing first, waiting, and hoping the connection holds. Here there is nothing to wait for: the file is read where it already sits, on your machine, and the cut happens in the tab.

The honest limit is your device, not our server. The upload card accepts files up to 50 MB, and a dense scan near that mark can make an older phone work hard for a minute. A laptop shrugs it off.

If the receiver insists on a single attachment, splitting is the wrong shape. Compress the PDF instead: smaller file, same pages. Many documents shed enough weight to slip under an email cap in one pass.

And if the big file is a bank statement, skip the manual ranges. The statement splitter reads the dates and cuts a multi-month statement into one PDF per month for you.
