Batch Process Multiple PDFs at Once
Processing PDFs one at a time is slow when you have a hundred files. Batch processing applies the same operation to every file in a folder — compress them all, convert them all, or protect them all — with a single setup. Each file is processed individually on your device. Nothing is uploaded.
How to Batch Process Multiple PDFs at Once
- 1Select all the PDFs you want to process
Drag and drop multiple files into the batch tool, or select a folder. The tool lists all files with their sizes. You can remove files from the list or add more later.
- 2Choose the operation to apply
Pick from compress, convert to Word, convert to JPG, protect with password, or flatten. Each file gets the same operation with the same settings. For mixed operations, run separate batch jobs.
- 3Configure the operation settings
Set the parameters for your chosen operation. Compression level for compress, password for protect, output format for convert. The same settings apply to all files. Adjust a setting and the file list updates with estimated results.
- 4Process all files
Click process. The tool runs the operation on each file one at a time in your browser. Progress is shown per file. Larger files take longer. Processing multiple files may take time as each is handled individually.
- 5Download the results
Download individual processed files, or download all as a ZIP archive. The ZIP preserves your original filenames so you can match inputs to outputs. Processed files are stored in your browser memory until you download them.

Apply the same operation to many files at once. All processing stays on your device.
Batch Process NowFrequently Asked Questions
How many PDFs can I batch process at once?
The tool is limited by your browser's memory. Typical desktop browsers handle 20-50 files at a time depending on file sizes. Very large files (100MB+) will reduce the count. For best results, process files in batches of 10-20.
Can I pause or cancel a batch operation?
Yes. Each file's processing shows a progress indicator. You can stop the batch at any time. Already-processed files are not discarded — you can download them even if the batch was interrupted.
Can I apply different operations to different files in the same batch?
No. The batch tool applies one operation with one set of settings to all selected files. For mixed operations, run separate batch jobs for each operation type and organize the outputs yourself.
Will batch processing drain my laptop battery?
Yes, batch processing is computationally intensive. Each file is processed in sequence, so 50 files will use more CPU than one. For laptops, plugging in during large batches is recommended. Desktop users won't notice any impact.
Does batch processing work on mobile devices?
It works but mobile browsers have more limited memory. Process 3-5 files at a time on mobile. Desktop or laptop computers are recommended for batch operations with more than 10 files.
All files stay on your device
Batch processing runs entirely in your browser. Every PDF, regardless of sensitivity, is processed locally. Your files never get uploaded to any server — even the batch results are assembled in-browser.
