Cut your document into two distinct parts without uploading it.
If you have a large document (such as a rental application or a corporate report) and want to email it, the size might block it from sending. Our tool allows you to split the PDF into two lighter files. The operation runs entirely in your browser: your contracts never transit through any external server.
Import the large PDF file or complete catalog that you need to separate.
Enter the number of the marker page that will serve as the dividing line to cut the file into two blocks.
The script divides the file layout and instantly downloads a compressed archive containing your two new PDFs.
Splitting PDF documents is a recurring business requirement when dealing with composite files that combine multiple independent subsections, such as a batch of monthly invoices merged into a single export, or a heavy contract containing bulky technical appendices that need to be isolated. Dividing the document at a precise structural pivot point allows you to neatly segment your records, stay within the file attachment limits of email clients, and distribute only the relevant sections to your associates or clients.
On the front-end JavaScript development side, the application orchestrates a high-performance computing pipeline by combining the pdf-lib and JSZip frameworks. The script extracts the binary stream from the source file, asynchronously generates two fresh document instances, and intelligently distributes the targeted pages using the copyPages cloning method. The two resulting sub-files (`partie_1.pdf` and `partie_2.pdf`) are wrapped on the fly inside a local ZIP archive. This closed-loop client-side execution ensures that none of your confidential agreements or financial records ever transit over the web.
Web browsers block triggering multiple independent file downloads simultaneously for security reasons. Packaging your two new PDF documents inside a single ZIP archive allows us to bypass this restriction smoothly and efficiently.
Yes, absolutely. The splitting process natively isolates and copies the page tree structure without applying any graphical rasterization or pixelation. Interactive hyperlinks, editable form fields, and vector typography font definitions remain fully functional.
