Universal File Merger

Universal File Merger — PDF, Word, Excel, PPT Combined (2026)

DocEasy's Universal File Merger is a single tool for combining multiple documents — PDF, Word (.docx), Excel (.xlsx), and PowerPoint (.pptx). Choose your file type, upload multiple files, reorder them with the arrow buttons, and download the merged result directly. Everything runs in your browser — nothing uploads to any server, and your documents stay completely private.

How to Use — Step by Step

1. Step 1 — Choose file type: Click the toggle for PDF, Word, Excel, or PPT.
2. Step 2 — Upload files: Drag and drop or click to browse. At least two files are required.
3. Step 3 — Reorder (optional): Use ▲▼ arrows to change merge order.
4. Step 4 — Configure options: Customize settings like bookmarks, page breaks, or Excel sheet merging.
5. Step 5 — Click "Merge Files": Processing happens locally — takes seconds.
6. Step 6 — Download: Save your single combined file, or the ZIP bundle for PPT.

How PowerPoint (PPT) Bundling Works

Important to know: True PPTX merging — combining multiple .pptx files into one editable presentation — is not possible in any browser-based tool, because PowerPoint files are complex ZIP archives containing linked XML parts, themes, slide masters, and media. Any tool claiming to "merge PPTX client-side" either uploads your file to a server or produces a corrupted file.

Instead, DocEasy takes the honest approach: it bundles your multiple .pptx files into a single, numbered ZIP archive, preserving each file's original quality and editability. Inside the ZIP you also get a README with instructions. This means:

• Each PPTX file stays 100% intact and editable in PowerPoint, Google Slides, or WPS Office.
• Files are numbered (01, 02, 03…) in the exact order you arranged them.
• Everything is compressed for easy download and sharing.
• 100% private — nothing is uploaded to any server.

If you need a single continuous document, we recommend: (1) Use our PPT to PDF tool to convert each deck to PDF, then (2) Use our PDF Merger to combine them into one file. This gives you a proper, single, shareable document.

Word & Excel Merging

Unlike PPT, Word (.docx) and Excel (.xlsx) files can be truly merged in the browser. DocEasy uses JSZip and SheetJS to combine the files:

• Word: Combines all paragraphs, tables, and inline images from every document into one continuous .docx. Optional page breaks keep documents visually separated. Formatting, fonts, and colours are preserved.
• Excel (Sheets mode): Each source file becomes a separate sheet in the merged workbook — great for keeping monthly reports distinct.
• Excel (Rows mode): All rows from every file are stacked vertically into one sheet — ideal for consolidating many reports into a single master list.

Common Use Cases

• Legal & Admin: Combine case documents, briefs, and exhibit files

Privacy and Security

• No uploads: Files stay on your device
• No server storage: Nothing is saved anywhere except your own computer
