Is there a maximum file size for splitting PDFs in FixTools?

FixTools processes PDFs in your browser, so the limit is your device's available RAM rather than a server upload cap. Modern computers can typically handle files of 200–500MB without issue.

Why is a large PDF slow to process?

Large files take more time because all processing runs on your device CPU. A fast desktop or laptop will handle large PDFs significantly faster than a mobile device.

Can I split a 300-page PDF into chunks of 50 pages?

Yes. Use the "split every N pages" option to divide your document into equal chunks. A 300-page PDF split every 50 pages produces six output files.

Does splitting a large PDF reduce image quality?

No. FixTools extracts pages without re-encoding content. Image resolution and text sharpness are preserved in split output files.

What if my large PDF is too slow to load?

Try closing other browser tabs to free up memory, or switch to a more powerful device. Very large scanned PDFs with many high-resolution images require the most resources.

Upload your large PDF. Processing happens in your browser, so file size is limited only by your device RAM — typically 500MB or more on a modern computer. Split by range, page count, or individual pages.
