Fileacy - File Converter (Offline)

Convert images, PDFs, Excel, CSV and JSON files instantly. Merge, split and rotate PDFs. Runs locally on your device.

Fileacy is a file converter that runs entirely inside your browser. No uploads, no accounts, no servers. Every conversion happens locally on your device using your own hardware. Most online converters work by sending your documents to a remote server - meaning your contracts, spreadsheets, and personal files are transmitted to infrastructure you don't control. Fileacy takes a different approach. Open a file, choose an output format, convert. Nothing leaves your machine at any point. The extension supports conversions across common document, image, and spreadsheet formats. PDF operations include merging, splitting, and rotating. Image conversions run through the browser's native canvas engine. Spreadsheet exports work directly from the file without any cloud processing. Fileacy works fully offline after installation. There are no API calls, no analytics on your files, and no network activity during any conversion. Built for people who work with documents regularly and want a fast, private alternative to uploading files to websites they don't control.
