Why JustDownSize
Split PDFs without sharing your files
When you split a PDF on most online tools, your document goes to a remote server. JustDownSize runs entirely in your browser — no server ever receives your PDF. Ideal for confidential contracts, medical records, and legal documents.
Features
Custom page ranges
Enter ranges like "1-3, 5, 8-12" to extract exactly the pages you need into separate PDFs.
Split every N pages
Divide a long document into equal chunks — for example, split a 30-page PDF into 5 PDFs of 6 pages each.
ZIP download
All split PDFs are bundled into a single ZIP archive for convenient download and sharing.
Use Cases
When to split a PDF
Extracting specific pages
Pull a specific clause from a contract, extract one chapter from a book, or isolate a single page from a report — without editing the original document.
Splitting scanned documents
When you scan a large batch of documents into one PDF, splitting divides them back into individual files — each contract, each receipt, each form gets its own PDF.
Sharing partial content
Extract the pages you're allowed to share from a larger confidential document, without exposing the full content to recipients who only need part of it.
Email attachment limits
Split a large PDF into smaller parts that fit within email attachment size limits — commonly 10MB or 25MB — then send as separate emails.
