Split PDF files online for free with ImageWizo. Upload a PDF, choose the available split options, and download the resulting PDF files.
ImageWizo PDF Split is an in-browser document extraction and page partition suite engineered to extract specific pages, isolate custom page ranges, or burst a multi-page PDF into separate standalone document files. Powered by client-side pdf-lib execution and PDF.js thumbnail rendering, this utility enables users to visually click and select individual pages, type complex range syntax (e.g. "1-3, 5, 8-12"), or split an entire document after every N pages with instant ZIP archive bundling. Whether you are extracting sensitive schedules from a corporate legal contract or separating scanned chapters from an academic binder, your files are processed entirely in local memory with zero remote server upload queues.
Local File Processing: File processing is performed locally in your browser rather than uploaded to an ImageWizo processing server. All processing for PDF Split happens directly inside your web browser using client-side technologies and local device memory.
When you upload a PDF, the browser reads the file into a local ArrayBuffer and renders visual thumbnail previews of every page using PDF.js. When you specify a split mode—such as Extract Selected Pages, Split by Range (e.g., "1-3, 5-8"), or Burst Every Page—the pdf-lib engine parses the root cross-reference dictionary and extracts the exact content streams and font resources for each target page. The engine creates new standalone PDF documents containing only the requested pages, recalculates the internal page tree, and packages the results into a single clean ZIP archive or individual file download. Supported file processing is performed locally in the browser rather than on an ImageWizo processing server.
Drag and drop any multi-page PDF document into the workspace or browse from your device storage.
Choose between "Extract Selected Pages" (visual click selection), "Custom Page Ranges" (e.g. 1-4, 7-10), or "Split Every N Pages".
Click directly on page thumbnail cards to toggle selection, or type custom page numbers into the range input box.
Click Split PDF to initiate instant client-side page-tree isolation and stream serialization.
Download your extracted PDF files individually or save the complete set packaged in an organized ZIP archive.
Inspect high-resolution visual thumbnails of every page and click to include or exclude pages instantly.
Support for intuitive range definitions such as "1-5, 8, 11-14" to extract complex multi-page subsets effortlessly.
Burst every single page into its own standalone PDF file and bundle the entire collection into a neat ZIP archive.

PDF Split does not convert pages into images or re-compress content streams; it extracts the original vector data and embedded images at 100% original fidelity.
Use commas to separate discrete pages (e.g., 1, 3, 7) and hyphens to define continuous sequences (e.g., 4-10). Ranges can be freely combined (e.g., 1-3, 5, 8-12).
PDF files protected with open/read passwords must be unlocked with their password before pages can be viewed or extracted.
When splitting a document into 10 or more separate files, use the single ZIP archive download button to prevent your browser from blocking multiple pop-up downloads.
Solution: Check the total page indicator before typing custom ranges. If a document has 20 pages, entering "21-25" will result in a validation error.
Solution: Unlock the file in Adobe Acrobat or your operating system PDF reader before loading it into the split tool.
Solution: Instead of typing page numbers manually, you can simply click on the thumbnail previews to highlight the exact pages you want.
Solution: Click "Download All as ZIP" to receive a single, organized archive file containing all extracted split documents.
Possible Cause: The uploaded PDF is protected with an owner or user security encryption password.
How to Fix: Remove the security password using your native PDF software before uploading the document.
Possible Cause: Large PDF documents with high-resolution image scans require browser memory to render visual thumbnails.
How to Fix: Allow the browser a brief moment to finish generating thumbnail previews in the queue.
Possible Cause: Some dynamic XFA forms store values in external XML streams rather than static PDF page objects.
How to Fix: Print the PDF to a standard "Print to PDF" file to flatten form fields before splitting.
Possible Cause: Your browser’s popup blocker prevented multiple concurrent automatic file downloads.
How to Fix: Use the "Download All as ZIP" button to save all extracted documents in a single bundle.
Glance at the visual thumbnails to verify you are selecting the exact page containing signatures or important clauses.
Split a large document into individual files, then use PDF Merge to recombine only the required pages in a new sequence.
When splitting into multiple separate files, the ZIP export keeps all extracted documents neatly contained in one folder.
Ensure you do not accidentally type letters or extra punctuation into the range box (e.g. use "1-4, 6" instead of "1 to 4 and 6").
