Split PDF by Exact File Size
Chop massive PDF files into smaller chunks to bypass strict email attachment limits (e.g., 20MB). Split documents intelligently without cutting pages in half.
Bypass Email Attachment Limits
You've finished a massive 150-page corporate report, but the PDF is 35MB. When you try to email it, Gmail rejects it due to the 25MB attachment limit. Instead of reducing the quality of the document, use this tool. You specify a target size (e.g., 20MB), and the algorithm calculates exactly how many pages can fit into that limit, automatically splitting the document into 'Part 1' and 'Part 2'.
Why Use Our PDF Split by File Size?
- Email Ready: Ensures no file exceeds standard 20MB/25MB limits.
- Intelligent Splitting: Only splits between pages; never cuts a page in half.
- Maintains Quality: Does not compress or ruin the resolution of the contents.
- Fast & Secure: Process heavy corporate documents entirely locally.
