Why Use an In-Browser Client-Side Image Converter?
Most web-based converters transmit your confidential images and documents to remote third-party cloud servers, exposing your files to privacy risks and enforcing strict file-size limits. Our client-side converter executes all decoding and re-encoding routines directly inside your device's browser memory via the HTML5 Canvas API, WebAssembly, and local decoding workers.
