Combine multiple PDF files into a single document in seconds. PDF merger works entirely in your browser - no uploads, no file size limits, and your documents stay completely private. Perfect for consolidating reports, contracts, invoices, or any PDF documents.
All merging happens in your browser. Your files never touch our servers - complete privacy guaranteed. No uploads, no cloud storage, no tracking.
Merge as many PDFs as you want with no file size restrictions. Combine hundreds of pages from dozens of files - no limits on file count or total size.
No compression or quality loss. Merged PDFs maintain original resolution, fonts, images, formatting, and interactive elements like links and forms.
Easily change the order of your PDFs before merging by dragging files up or down in the list. Get pages in exactly the sequence you need.
Once loaded, this tool works without internet since everything runs client-side. Perfect for sensitive documents or working in secure environments.
PDF merging is performed entirely in your browser using the pdf-lib JavaScript library. Your documents are never uploaded to any server - all processing happens locally on your device. We have zero access to your files. You can verify this by checking your browser's network tab during processing - you'll see no upload requests. This makes our tool ideal for confidential documents, contracts, financial records, or any sensitive PDFs.
There's no limit. You can merge 2, 10, or even 100+ PDFs in one go. Processing time depends on total file size and your device performance, but most merges complete in seconds.

No. Merging is lossless - all pages are copied exactly as-is with no recompression or quality degradation. Fonts, images, and formatting remain identical.
No hard limit, but browser memory constraints apply. Most devices handle 100-200MB total easily. Larger merges may be slow or fail on low-memory devices.
No. All processing happens in your browser using JavaScript. We never see your files. Check your browser's network activity to verify.
Only if you can open them (user password for viewing). PDFs with editing restrictions (owner password) cannot be merged without unlocking first.
Links within pages are preserved. Document-level bookmarks are not currently maintained - merged PDF has no outline. Use professional PDF tools if bookmarks are critical.
