About Batch PDF Processing

Save time by processing many PDF files at once. Merge a folder of documents into a single PDF, compress a batch of files for email, or rotate every page in a set of scans. Everything runs locally in your browser with pdf-lib — no uploads, no queues, no signup.

Multi-File Input

Drag in as many PDFs as you need. Each file appears in the queue with live status as it's processed.

Operation Choice

Merge everything into one document, or compress and rotate each file individually before bundling the results.

Queue Progress

Watch each file move from waiting to done with a progress bar, and see the result ZIP built automatically.

100% Private

No server uploads. Files are processed directly in your browser with the pdf-lib library and never leave your device.

📋 Common Use Cases

Frequently Asked Questions

Is this PDF tool really free?▼

Yes. Every PDF tool on iluv.tools is completely free. No signup, no account, no payment. Everything runs in your browser.

Are my PDF files uploaded to a server?▼

No. All PDF processing happens locally in your browser using the pdf-lib and PDF.js libraries. Your files never leave your device.

How many PDFs can I process at once?▼

There is no hard limit on the number of files. Keep in mind that memory is shared across all files, so very large sets may slow down on low-end devices. For heavy batches, process in smaller groups.

Can I mix different operations on one batch?▼

Choose one operation per batch: merge combines all files into a single PDF, while compress and rotate process each file individually and bundle the results into a ZIP. Run the batch again with a different operation if you need multiple steps.

Is there a file size limit?▼

Browser-based tools handle files up to ~100MB smoothly. Larger files may be slower depending on your device. For very large PDFs, try splitting them first, processing the parts, then merging.

Can I use these on mobile?▼

Yes. All PDF tools work on mobile browsers (iOS Safari, Android Chrome). Desktop is recommended for large files, but everything is functional on mobile.
