How it works
This tool compresses images directly in your browser using the Canvas API. No files are uploaded to any server — processing happens entirely on your device. Adjust the quality slider to balance file size and image quality.
Frequently asked questions
No. All processing happens locally in your browser. Your images never leave your device.
JPEG, PNG, and WebP images are supported. JPEG images typically achieve the best compression ratios.
PNG is a lossless format. For significant size reduction, the image is converted to JPEG during compression. If you need to keep PNG format with transparency, the compression ratio will be limited.
