The free online image compressor lets you shrink JPEG, PNG, WebP, and BMP images right in your browser. A smart compression algorithm paired with an adjustable quality slider helps you find the perfect balance between file size and image clarity. Batch process up to 10 files at once (50 MB per file limit). Everything runs locally — your files never leave your device.Pain Point

Highlights
Drop in images, adjust quality, download — the whole flow takes under 10 seconds. Batch mode handles multiple images at once, and the quality slider lets you find the sweet spot between file size and clarity. For everyday compression needs, this is the fastest path compared to traditional editing tools.Use Cases
