The QR & Barcode Tools collection at Alee Tools provides 19 dedicated single-purpose utilities built to solve specific challenges quickly and accurately. Whether you need to compress media, parse complex formats, or generate assets for production, every operation executes 100% locally in your web browser.

Hardware Accelerated
