Ahrefs Domain Rating set in type 3 Nov 2026, reset 2 Nov 2026.
A free online tool that compresses images and files to an exact target size entirely in your browser without uploading data to external servers.
File Compressor Online is a privacy-focused image and file compression tool that operates entirely within your web browser using JavaScript and HTML5. It allows you to compress JPG, PNG, WebP, and GIF files to an exact target KB size without sacrificing image quality or original resolution. The tool removes invisible bloat such as camera metadata and GPS tags while keeping pixel dimensions intact.
Unlike traditional online compressors that upload files to cloud servers, File Compressor Online processes everything locally in your browser sandbox, ensuring zero bytes of your data leave your device. This makes it particularly suitable for compressing sensitive documents like passports, visas, and government forms with specific file size requirements. The service is completely free with no subscriptions, daily limits, or watermarks.
