Combining multiple PDFs into a single file is one of the most common document tasks. Whether you're assembling a report from multiple chapters, merging scanned pages, or combining invoices for a client, iLoveConvert's free PDF merger handles it instantly in your browser. No file size limit. No account needed. Your documents never touch our servers.
Most PDF mergers upload your files to a cloud server — raising serious privacy concerns. Our tool uses the PDF-lib JavaScript library to merge everything locally in your browser. The result is a perfectly structured PDF with all pages in the exact order you specify.
Click the upload area or drag and drop your PDF files. Add as many files as needed.
Drag the file cards to arrange them in the order you want in the final PDF.
Hit the Merge PDF button. Processing happens instantly in your browser.
Your combined PDF downloads automatically. No watermark, no sign-up.
There is no hard limit. You can merge as many PDFs as your device memory supports. For very large files, we recommend merging in batches of 10-15.
No server-side limit because processing is entirely local. Practical limits depend on your device RAM — most modern phones and laptops handle files up to 100 MB per document easily.
No. iLoveConvert uses lossless PDF merging — text, images, and vector graphics retain 100% of their original quality.
Password-protected PDFs need to be unlocked first. Use our Unlock PDF tool, then merge.
Never. All merging happens using PDF-lib running locally in your browser tab. Files stay on your device.
