Merging PDFs is one of the most common document tasks, whether you're combining reports for a meeting, assembling a proposal from multiple sources, or putting together receipts for an expense report. FixMyPDF.ai makes it fast and completely private — your files never leave your browser.
Drop your PDF files into the upload area or browse files. You can add as many files as you need. Drag the files to rearrange them in any order — the first file becomes the first pages of the combined PDF, the second file follows, and so on. When you're ready, click "Merge" and your combined PDF downloads instantly.
Unlike most online PDF tools that upload your documents to a remote server, FixMyPDF.ai processes everything directly in your web browser using JavaScript. Your sensitive documents — contracts, financial statements, medical records — never leave your computer. There is no server, no cloud storage, and no third party that ever touches your files.
Our merge tool works on Mac, Windows, Linux, Chromebook, iPhone, iPad, and Android. There's nothing to install — just open the page and start combining. It works in Chrome, Safari, Firefox, Edge, and any modern browser.
People use our merge tool to combine invoices and receipts for tax filing, assemble multi-section reports into a single document, join scanned pages into one file, merge cover letters with resumes, put together real estate paperwork, and combine insurance or medical documents. Any situation where you need multiple PDFs in one file — this tool handles it.
Most online PDF tools — including iLovePDF, SmallPDF, and Adobe Acrobat online — upload your files to their servers for processing. That means your contracts, tax documents, medical records, and confidential business files pass through a third party's infrastructure. FixMyPDF.ai is different: every tool runs entirely in your web browser using client-side JavaScript. Your files are never uploaded, never stored on a server, and never accessible to anyone but you. There is no backend server processing your documents — it all happens on your device.
Is there a file size limit? Each file can be up to 50MB. For very large merges, the processing happens entirely in your browser's memory, so performance depends on your device.
Does merging reduce quality? No. Merging copies the original pages exactly as they are — no re-rendering, no compression, no quality loss whatsoever.
Can I change the page order? Yes. Drag files in the list to reorder them before merging. For more granular control, use our Reorder Pages tool after merging.
Is it really free? Yes. You get 2 free uses per day. Need more? Go Pro for unlimited access to all 16 tools for $9/month.
