Why Use Client-Side Image Compression?

Data Privacy: Photos are rendered and compressed via HTML5 Canvas within your local browser sandbox. Image data is not transmitted to external storage servers.
Fast Local Processing: Because files do not need to be uploaded to a remote processing server, processing can be faster and avoids network upload time. Actual processing speed depends on your device and image size.
Broad Format Support: Compatible with common web graphics including JPEG/JPG, alpha-channel transparent PNGs, and modern WebP.
Bandwidth Saver: Lighter graphics help optimize web performance metrics, reduce bandwidth bills, and conserve local disk space.

Are transparent PNG backgrounds preserved?

Yes. When working with PNG images, the transparency layer is preserved during the browser canvas rendering workflow.

Is there a limit on how many images I can compress?
