Why Bulk PDF Delivery Still Requires Manual Zipping

Client portals need to bundle invoices. SaaS apps need to package reports. But creating ZIP archives server-side requires storage, memory management, and cleanup logic. Engineers waste days building file archiving pipelines that break under load.

Server-Side Storage

Downloading 100 PDFs to zip them requires GB of disk space and cleanup logic.

Memory Leaks

ZipStream, archiver, JSZip—all have quirks that crash servers under load.

Slow Bulk Downloads

Zipping 500 invoices takes minutes. Users abandon downloads mid-stream.

The hidden cost

Engineering teams spend 25+ hours per quarter building and maintaining bulk PDF download features. Memory leaks cause server crashes during peak usage. One reliable API eliminates this entirely.

FAQ: PDF to ZIP Archiving

Common questions about bundling PDFs into ZIP archives

How many PDFs can I bundle into one ZIP archive?

xspdf supports up to 1,000 PDFs per ZIP on standard plans, and 10,000+ on enterprise plans. Total ZIP size is limited to 5 GB (standard) or 50 GB (enterprise). For quarterly invoice packages or annual report bundles, this covers 99% of use cases. If you need larger archives, contact our team for custom limits.

Can I rename files inside the ZIP archive?

Yes. Instead of an array of URLs, pass an array of objects with "url" and "filename" keys. Example: {"url": "https://s3.amazonaws.com/invoices/abc123.pdf", "filename": "invoice_001.pdf"}. xspdf renames files inside the ZIP automatically. Perfect for creating user-friendly download packages with sequential numbering or custom labels.

Does xspdf support password-protected ZIPs?

Yes. Set "password": "your_secure_password" in the options to encrypt the ZIP with AES-256 encryption. This is critical for client portals delivering sensitive documents (invoices, contracts, medical records). Users need the password to extract files. For maximum security, generate unique passwords per client and transmit them separately from the ZIP URL.

What happens if one PDF URL fails during archiving?

By default, xspdf returns an error if any PDF URL is unreachable or invalid. For fault-tolerant archiving, enable "skip_errors": true in the options. xspdf will skip failed PDFs and bundle the rest. The response includes a "skipped_files" array listing which URLs failed, so you can retry them separately or log the issue for investigation.

How do I deliver ZIP archives to end users in my app?

xspdf returns a temporary download URL (valid for 24 hours) or outputs the ZIP directly to your S3/GCS bucket. For client portals, generate a signed URL from your storage bucket and send it via email or display it in the UI. For instant downloads, proxy the xspdf URL through your backend to add auth checks. See API docs for secure delivery patterns.
