Frequently Asked Questions
Yes, it is 100% free with no watermarks, sign-up or file limits. Everything runs directly in your browser.
No. Merging happens entirely on your device using JavaScript, so your documents stay completely private and are never uploaded to a server.
Yes. Drag the files to reorder them, or use the up and down arrows. The merged PDF follows the order shown in the list, top to bottom.
You can merge as many PDFs as your device memory allows — there is no fixed limit. Very large files simply take a little longer to process.
Standard, unencrypted PDFs merge perfectly. Some password-protected or heavily encrypted files may fail to load, in which case you will see a friendly error message.

Merge PDF Files Free, Without Uploading Anything

Toolixa's PDF Merger combines several PDF documents into one seamless file, right inside your browser. It is ideal for assembling reports from separate chapters, joining scanned pages, bundling invoices, or putting together an application package from multiple sources. Because the entire process runs locally with JavaScript, your files never touch a server — a genuine advantage when you are working with confidential contracts, financial statements or personal records.

How to Merge PDFs

Drag your PDF files onto the drop zone, or click Browse Files to select them. Each file appears in a list showing its name, size and total page count so you can confirm you have the right documents. Arrange them in the order you want by dragging the rows or using the up and down arrows, remove any file with the ✕ button, then click Merge & Download PDF. Your combined document downloads instantly.

Full Control Over Page Order

The order of files in the list is exactly the order of pages in the final PDF, built from top to bottom. This makes it simple to place a cover page first, insert an appendix at the end, or interleave documents in a specific sequence. The live page count next to each file helps you predict the length of the merged result before you download it.

Private and Secure by Design

Most online PDF tools require you to upload sensitive files to remote servers and trust that they will be deleted afterwards. Toolixa takes a different approach: nothing is uploaded, nothing is stored, and no account is required. Once the page has loaded you can even disconnect from the internet and the merger will still work, because all the processing happens on your own machine.

Tips for Smooth Merging

For the fastest results, keep individual files reasonably sized and close other memory-heavy browser tabs when merging very large documents. If a file refuses to load, it may be encrypted or password-protected — remove the protection first, then try again. Once your merged PDF is ready you can split it back into images with our PDF to JPG tool, or create fresh PDFs from photos using JPG to PDF.
