About Split by Size - break PDFs under a size limit
Split by Size is a free PDF editing tool that breaks a large PDF into smaller chunks, each below a target size in megabytes. It is the fastest way to get past email attachment limits, portal upload caps, or Slack and WhatsApp file-size restrictions. Set a maximum MB per part and Docvexa automatically distributes pages so every output file stays below the threshold. Because splitting runs in your browser, sensitive files never leave your device - making this one of the most reliable PDF editing services for confidential batches. No sign-up, no watermark, and no limit on how many PDFs you split.
