This free tool merges multiple PowerPoint (PPTX) files into one in your browser. Order the files, choose the output slide size (dimensions or aspect ratio), set the output filename, and download the combined presentation.

• Combine PPTX files: Two or more presentations become one. File size is shown next to each filename; total size is shown.
• Output slide size: Choose how the merged deck's dimensions are set—use the first file's dimensions, use the largest (max width × max height across all files), or use dimensions from a specific file. Preserves or fits aspect ratios (e.g. 16:9, 4:3).
• Reorder: Use the up/down arrows; the order of files is the order of slides in the merged file. Use Clear all to remove all files or Choose more files to add more.
• Custom filename: Set the name of the merged PPTX before download.
• Client-side and private: Your files are never uploaded; processing runs in your browser.

Merging is useful for combining chapters, sections, or multiple decks into one presentation for a single download or presentation. If your files use different slide sizes or aspect ratios (e.g. 16:9 and 4:3), you can choose the output dimensions—use the first file, the largest, or pick a file—so the merged result fits your needs.

Add two or more PPTX files (file size shown per file), arrange their order with the arrows, and choose the output slide size: use the first file's dimensions, the largest dimensions across all files, or dimensions from a specific file. Use Clear all or Choose more files as needed, set the output filename, and click Merge and download. The tool combines all slides in order with your chosen dimensions and lets you download the result.

• Put the file that has the theme or dimensions you want first, then add others. The merged deck uses the first file's layout and theme.
• If sources use different aspect ratios (e.g. 16:9 and 4:3), choose "Use largest" so nothing is cropped, or "Use dimensions from" a specific file to match that ratio.
• Check the total file size before merging; very large sets may take a few seconds to process in the browser.
