Automate your workflow. Our Batch PDF Processor allows you to apply actions like compression, flattening, or metadata removal to hundreds of PDF files simultaneously, directly in your browser.
What is Batch Processing?
Instead of opening, editing, and saving files one by one, batch processing handles a whole folder of documents in a single queue. This tool is essential for organizations that need to standardize archives or sanitize documents before publication.
Client-Side Bulk Engine
We utilize JavaScript web workers to process your files in parallel on your own machine. This means you can process 50 files as quickly as your CPU can handle it, without waiting for 50 uploads and 50 downloads.
How to Bulk Edit PDFs
- Upload: Drag & drop multiple PDF files (or a folder).
- Select Action: Choose from Compress, Clean Metadata, or Flatten.
- Process: Click "Start". Watch the progress bar as each file is modified.
- Download: Get all your processed files back in a single ZIP archive.
Available Actions
- Bulk Compress: Optimize file size for storage.
- Sanitize Metadata: Remove names, dates, and software info for privacy (GDPR compliance).
- Flatten Forms: Lock interactive fields to prevent further changes.
Specifications
- Capacity: Unlimited files (dependent on device RAM).
- Output: ZIP archive containing modified PDFs.
- Speed: Instant local processing.
Professional Use Cases
- Legal Discovery: Flattening hundreds of evidence files to ensure they remain unaltered.
- Archiving: Compressing a year's worth of invoices to save disk space.
- Publishing: Cleaning metadata from whitepapers before public release to protect author identity.
Zero-Data Retention
Processing bulk files online can be a security risk if they are uploaded to a cloud server. PDFPlug is different: all bulk operations happen offline in your browser tab. Your files never leave your computer.
Free vs Premium
Free Version: Unlimited batch size for compression and cleaning.
Premium Version: (Future) Advanced batch OCR and batch watermarking.
Frequently Asked Questions
Does it rename my files?
No, we keep the original filenames inside the ZIP file so you can easily replace your originals.
My browser crashed with 500 files?
Browsers have memory limits. For massive batches, try processing 50-100 files at a time.
Individual Tools
Need specific changes? Compress PDF for detailed settings per file, Merge PDF to combine them instead of zipping, or Scan to PDF to add new documents.
