About the Image Compressor
Oversized images are the number-one cause of slow web pages. This compressor reduces JPG, PNG and WebP file sizes using your own browser's image encoder — the file never leaves your device, so there is no upload wait, no queue and no privacy concern. Drag in a photo, tune the quality slider and watch the before/after sizes update live; when the balance looks right, download the compressed copy instantly.
