Free PDF Splitter — Split by Pages or File Size, In Your Browser
Email attachment limits, document control systems, and code-review portals all cap PDF size at 5–25 MB. This tool splits a large drawing set, report, or scanned document into manageable chunks — without uploading anything.
How to use it
- Drop your PDF into the upload zone (or click to browse).
- Choose a split mode: by page range ("1-50, 51-100"), by fixed page count, or by maximum file size in MB.
- Hit split. The tool generates each part and offers download links.
- Bonus: rename each part before download.
Frequently Asked Questions
Does my PDF get uploaded?
No — everything happens in JavaScript inside your browser. Open DevTools → Network and you'll see no PDF data leaving your machine.
Is there a file-size limit?
Practical limit is your browser's available memory — typically 1.5–2 GB before things get sluggish. For larger files, use desktop tools like RHCES Tools or qpdf.
Does it preserve form fields and bookmarks?
Pages are extracted as-is. Form fields scoped to a single page survive; bookmarks are rebuilt to point only at retained pages.
What about encrypted/password-protected PDFs?
You'll be prompted for the password before splitting. The password stays in browser memory and is never transmitted.
