Split PDF: Free, Private, No Upload
Break a PDF into smaller files in your browser: every few pages, by file size or by custom page ranges.
- Never uploaded
- No sign-up
- Free, no limits
Three Split Modes
By page count, by file size, or custom ranges
Size Limits
Keep every part under an email attachment cap
Local File Processing
Your PDF file stays in your browser
Split a PDF without uploading it
PDF Perfect splits PDFs inside your browser. Split by a fixed number of pages, by a maximum file size or by your own page ranges, then download each part. The PDF file is not uploaded to PDF Perfect.
How to split a PDF
- 1
Select your PDF
Drag your PDF onto the drop zone, or click it to choose a file from your device.
- 2
Choose how to split
Pick By Pages (for example 1 page per file), By Size (each part under a set number of MB) or Custom Ranges (such as 1-3 and 4-10).
- 3
Download the parts
Click Split PDF, then download each part on its own or use Download All. No account needed.
Which split mode should I use?
If you only want to keep a few pages as a single new PDF, Extract PDF Pages is quicker.
| Mode | What it does | Typical use |
|---|---|---|
| By Pages | Makes a new file every N pages | One file per page, or per chapter of equal length |
| By Size | Keeps every part under a size you set | Email attachments and upload portals with MB caps |
| Custom Ranges | Makes one file per range you enter | Separating sections, invoices or chapters |
Is it safe for confidential documents?
PDF Perfect has no PDF upload endpoint. The split happens in JavaScript on your device, and your browser creates the download without sending the PDF file or its contents to PDF Perfect.
The website still makes ordinary requests for pages, fonts, analytics, feedback you submit and, when enabled, advertising. Open your browser's Network tab while you process a file to confirm that none of those requests carries the PDF.
How to check that your file never leaves your deviceLimits
- The file picker accepts PDFs up to 1 GB, but available device memory sets the practical limit. Splitting by size takes longer because each part is measured as it's built.
- A single page larger than your size limit is kept as its own file.
- Password-protected PDFs aren't supported. Remove the password first.
