Split PDF
Extract every page as its own PDF, or pull a contiguous range. Thumbnails help you confirm page numbers before export.
Splitting vs merging: when to use each
Split when you need to email one chapter, archive a single signed page, or remove an appendix. Merge when you have many sources that should read as one document. DoItSwift keeps both flows local: thumbnails come from PDF.js rendering, while pdf-lib cuts the actual PDF objects so text remains selectable when the source was a proper digital PDF (scanned pages behave like images inside the file).
Range mode produces one PDF containing only pages start through end inclusive. “Every page” mode zips multiple single-page PDFs — ideal for distributing slides as separate attachments.
Frequently Asked Questions
Why only one PDF at a time?
Splitting is page-focused; batching multiple source PDFs would confuse numbering. Use merge first if needed.
Are page numbers 1-based?
Yes — first page is 1, matching what you see on thumbnails.
Is my PDF uploaded?
No — processing stays in your browser tab.
Encrypted PDFs?
Password-protected files may fail to load unless decrypted first.
Large PDFs over 50MB?
May take time or stress memory — close other tabs and wait.
