FAQ
Everything you need to know about PDF Splitter.
Is PDF Splitter free to use?
Yes. PDF Splitter is completely free with no account required, no usage limits, and no hidden charges.
Are my PDF files uploaded to a server?
No. Your files never leave your device. All splitting is done entirely in your browser using JavaScript. Nothing is uploaded, transmitted, or stored anywhere.
How do I split a PDF by file size?
Upload your PDF, select 'Split by file size', enter the maximum size per part in MB, then click Split. The tool will divide your PDF and bundle the parts into a ZIP file for download.
How do I split a PDF by page count?
Upload your PDF, select 'Split by pages', enter how many pages each part should contain, then click Split. You'll receive a ZIP file containing all the smaller PDFs.
Is there a file size limit?
There is no limit imposed by us. However, very large files (500MB+) may be slow depending on your device's available memory and processing power, since everything runs locally on your machine.
What browsers are supported?
PDF Splitter works on all modern browsers — Chrome, Firefox, Edge, and Safari. We recommend using the latest version of your browser for the best performance.
Can I use PDF Splitter on my phone?
Yes, it works on mobile browsers. For large files, a desktop or laptop is recommended as it has more memory and processing power.
Why is the output a ZIP file?
When splitting a PDF into multiple parts, bundling them in a ZIP makes it easy to download all parts in one click instead of downloading each file separately.
Will the quality of my PDF be affected?
No. PDF Splitter only extracts pages from your PDF — it does not re-encode, compress, or alter the content in any way. The output files are identical in quality to the original.
