What is FileMerger?

FileMerger is a free, privacy-first web application designed to merge, combine, and organize data and documents directly in your browser.

Unlike traditional online converters that upload your sensitive documents to remote cloud servers, FileMerger processes all files 100% client-side using modern browser technologies (WebAssembly & Web Workers). Your data never leaves your device, making it ideal for confidential business spreadsheets and GDPR compliance.

Key Features: • Excel & Spreadsheets: Merge multiple .xlsx, .xls, and CSV files into unified datasets with automatic column mapping. • JSON & Structured Data: Combine JSON arrays and objects with schema alignment. • PDF Tools: Merge multiple PDF documents or reorder and extract pages. • Media & Text: Stitch images (JPG, PNG, WebP) side-by-side or vertically, join audio tracks, and combine text/log files. • 100% Private: Zero server uploads. • Completely Free: No registration, subscriptions, or file upload limits.
