Consolidate multiple PDFs into single files with one API call. No formatting loss. Scale from 2 files to thousands daily.
Merging PDFs sounds straightforward. At scale, it's messy. Free online tools handle one merge at a time and require manual uploads—not production-ready. Desktop software requires human interaction and doesn't integrate with automation. Building it yourself means using open-source libraries that are fragile across different PDF versions, with binary format issues and rendering inconsistencies. You're debugging this instead of shipping features.
You need reliable, programmatic PDF merging that handles edge cases and scales without manual intervention. Our API does that. Control merge order precisely, combining specific page ranges from each PDF if needed. Preserve all fonts, colors, images, hyperlinks, and form fields—byte-for-byte fidelity to original files. Merge 10 files (100+ pages) in 3 seconds. Build complex workflows: trigger merges based on application logic, combine user uploads with templates, create dynamic document bundles, integrate with storage systems, email, and workflow tools. No corruption. No data loss. Just reliable merging at scale.
SaaS platform generated automated business reports. Each report needed: cover page (dynamic), executive summary (PDF template), data tables (generated), appendices (customer-uploaded PDFs). One API call merges all components in correct order, zero failures. Now delivering 1K+ custom reports monthly with no assembly errors.
Contract management startup needed to bundle executed agreements with witnesses, notarizations, and exhibits into single downloadable files for clients. Workflow: collect all contract pieces → merge via API → deliver to client. Simple, reliable, fast. Now handling 5K bundles/month without infrastructure headaches.
Insurance backend needed to combine multiple documents (claim form, supporting evidence, medical records, photos) into single PDF for underwriter review. Workflow: upload pieces → API merges in logical order → send to review queue. Replaced home-grown solution. Now processing 3K claims/month with 100% success rate.
Pass an array of PDFs—by URL (point to hosted files), by bytes (raw PDF data), or mixed. Get back single merged PDF with all content preserved. One API call, complete control.
All fonts, colors, images, hyperlinks intact. Page numbers, metadata, form fields preserved. Merge 10 files (100+ pages) in 3 seconds. No corruption, no data loss, byte-for-byte fidelity.
Control merge order precisely. Merge specific page ranges from each PDF (combine pages 1-5 from doc A with pages 10-15 from doc B). Insert blank pages between documents if needed.
Trigger merges based on application logic. Combine user uploads with templates. Create dynamic document bundles. Integrate with storage systems, email, workflows. Full automation at scale.
Full fidelity merging with no quality degradation. Every font, color, image, link preserved perfectly. Process 50-page PDFs in seconds. Handle edge cases: blank pages, rotated pages, embedded media.
Subscription for consistent monthly merging. Pay-as-you-go tokens for variable volume or testing. Scale with your business needs. See our pricing page for plan details.
Join companies using PDF Technologies API to merge thousands of documents monthly without infrastructure complexity.
Not directly in one call. You'd need to convert JPGs to PDF first (separate operation), then merge. We're exploring a combined "merge mixed media" operation—let us know if this is critical for your use case.
Free online tools exist, but they're manual, one-file-at-a-time, and you're uploading sensitive data to unknown servers. Our API is built for automation: merge 100 PDFs programmatically without human intervention. You pay for reliability and scale, not the merging itself.
Technically unlimited. All plans support the same features. Higher-tier plans provide larger volume limits and faster processing for batch operations. If you're regularly merging 50+ files at once, consider a higher-volume plan.
Starter: 25MB output. Professional: 100MB output. Higher-volume plans: Custom limits. Most use cases stay well under these limits. If you're merging massive files, you likely want to split them or compress images first.
Page numbers are preserved as they were in original files (so doc A's page 5 stays as page 5, not renumbered). Bookmarks are preserved but not re-indexed for the merged document. If you need bookmarks updated for the final merged file, that's a custom request.
Absolutely. You control the exact order: pass documents in the sequence you want them combined.
All hyperlinks are preserved and functional in the merged output. External links, internal document links, email links—all work.
Not directly. Use our password removal service first, then merge. Contact us if you need a combined workflow—available on all plans.
Free tools are fine for occasional merging. Our API is for automation: trigger merges based on business logic, handle thousands of files, integrate into workflows, no manual steps. Free tools can't do any of that.
Rare, but we return clear error messages indicating which specific PDF caused the issue. All plans include retry logic and automatic repair attempts for corrupted files.
Not in a single API call, but you can send multiple merge requests in parallel. Our API handles this efficiently across all plans. Higher-volume plans provide optimized processing speeds for batch scenarios.
