📖 How to Use

Reduce image file size without sacrificing visible quality — all processing happens in your browser, nothing is uploaded to any server.

Drag and drop your image onto the upload zone, or click to browse
Drag the quality slider — 70–85% is the sweet spot between size and sharpness
Choose your output format: JPEG for photos, PNG for logos/screenshots, WebP for smallest size
Click Compress Image and compare the before/after file sizes
Download your compressed image with one click

JPEG at 80% quality is usually indistinguishable from the original to the human eye
WebP produces 25–35% smaller files than JPEG at equivalent quality — great for websites
PNG is lossless — changing quality has no effect on PNG output (always full quality)
For profile photos and thumbnails, 60–70% JPEG quality is perfectly fine

JPEG, PNG, and WebP — you can also convert between formats while compressing.

At 70–85% quality, compression is usually indistinguishable from the original to the human eye.
