Troubleshooting

Q: Why is splitting slow?

Large PDFs take longer to process. This is normal and depends on your device's performance.

Q: Can I download files one at a time?

Yes! Each result has its own "Download" button for individual downloads.

Q: What happens if I define invalid page ranges?

The tool validates ranges and prevents errors. Start and end pages must be within the PDF's page count.

Q: Can I split the same PDF again?

Yes! Use the "Split Another" button to clear results and split a different PDF.

Q: Will splitting affect the original PDF?

No, your original file is never modified. All operations are non-destructive.

Q: What does "Image-based" badge mean?

Some PDFs use advanced features that require an alternative splitting method. In these cases, pages are converted to high-resolution images and embedded into new PDFs. The quality is preserved, but the resulting files may be larger and text may not be selectable.

Q: Why are my split files larger than expected?

If the "Image-based" method was used (indicated by an orange badge), files will be larger because pages are stored as high-quality images rather than native PDF content. This ensures compatibility with complex PDFs.
