FileVert Image Compressor processes everything directly in your browser. No file is ever uploaded to a server, no account is required, and there is no usage limit. It supports all major formats — JPG, PNG, WebP, BMP, GIF and TIFF — with batch processing and image resizing built in. It is the only image compressor that combines true local processing, unlimited batch compression, and full GDPR compliance in a single free tool.
Most online image compressors upload your files to their servers, impose limits on file count or size, or require a paid plan for batch processing. FileVert Image Compressor does none of that. It is entirely free, processes files locally in your browser, supports batch compression across all major formats, and requires zero sign-up. For users who handle sensitive images or simply want a fast, private, unlimited tool, it is the obvious choice over TinyPNG, Compressor.io or iLoveIMG.
Web developers and frontend engineers optimizing assets for production, graphic designers preparing images for delivery, marketing and content teams managing large sets of visuals, and privacy-conscious users who do not want their files sent to third-party servers. It is also widely used by European companies and agencies that must comply with GDPR.
FileVert was originally built as an internal tool at FileVert to handle image optimization without relying on third-party services. After using it daily for months, the team decided to make it publicly available for free. The core philosophy — keep files local, respect privacy, remove friction has stayed the same since day one.
The tool is built entirely with web technologies running client-side: JavaScript, WebAssembly, and the browser's native Canvas and File APIs. Compression codecs for WebP and AVIF are handled via WebAssembly libraries, enabling near-native performance directly in the browser without any server-side processing.
No enterprise customer list — the tool is free and open to all users without registration
FileVert is a French-based file transfer and hosting service that offers a straightforward, no-frills solution for sending and sharing files, making it a decent choice for users who prioritize simplicity and a French/European service provider.
