Batch Processor
About the Batch Processor
The Batch Processor tool applies a single operation — merging or splitting — across multiple PDF files at once, saving you from repeating the same action file by file when you have a whole folder of documents to process the same way. Rather than uploading files one at a time into separate tool sessions, you load your entire batch here and choose the operation you want applied across all of them.
In merge mode, every uploaded PDF is combined into one single output file, in the order the files appear in your list — functionally the same result as the standalone PDF Merger tool, but presented as part of this dedicated batch workflow. In split mode, each individual PDF in your batch is split into its own set of single-page files, so a batch of five ten-page PDFs would produce fifty individual page files, each labeled with its source filename and page number for easy tracing back to the original document.
This is particularly useful when you're processing a whole folder of similarly-structured documents at once: splitting an entire month's worth of scanned invoices into individual page files for a document management system, merging a week's worth of daily reports into a single combined file for archiving, or preparing a large batch of forms for individual-page distribution. Because both operations run through the same interface, you don't need to remember which standalone tool to open — just load your files and pick merge or split.
Split-mode output for a large batch can produce a substantial number of individual files at once, since every page of every uploaded PDF becomes its own download — your browser may prompt for permission to allow multiple downloads the first time you run a large batch split, which is expected behavior rather than an error. For more granular control over exactly which pages get extracted from a single file (rather than every page of every file), the standalone Page Extractor or Page Splitter tools offer that finer-grained targeting.
Before running a large batch operation, it's worth testing your chosen mode (merge or split) on just one or two representative files first, to confirm the output matches what you expect, before committing to processing dozens of files at once — this is especially useful the first few times you use split mode, since a large batch can produce a substantial number of individual downloads that are harder to review or redo if something wasn't quite right. If your files vary significantly in structure (some ten pages, some fifty), be prepared for a proportionally large number of output files in split mode, since every single page of every file becomes its own separate download.
Because everything runs locally in your browser rather than through a server-side job queue, there's no waiting in line behind other users' processing jobs and no risk of a service outage interrupting a large batch partway through — the entire operation, however many files it involves, runs at the speed of your own device from start to finish.
Step-by-Step Instructions
- Choose your operation from the dropdown: "Merge all into one PDF" or "Split each PDF into pages."
- Drag your PDF files onto the drop zone, or click to browse and select multiple files.
- Review the file list to confirm every document you want is included.
- Remove any file you don't need using its × icon.
- Click "Process Batch" to run the selected operation across every file.
- Your browser downloads the result — either one combined file, or many individual page files depending on your chosen mode.
