Image Compressor

Reduce the file size of JPEG, PNG, or WebP images directly in your browser — no upload to a server required. Use the quality slider to balance compression against visual fidelity, and see the before-and-after file sizes side by side. Smaller images load faster, score better on Core Web Vitals, and save storage costs.

All processing happens in your browser. No data is sent to any server.

Frequently Asked Questions

What file formats can I compress?
JPEG, PNG, and WebP images are supported. HEIC files should be converted to JPEG first.
How much can it compress an image?
Typical savings are 30–70% with minimal visible quality loss at the default quality setting, though results vary by image content.
Is my image uploaded to a server?
No — compression uses the browser's Canvas API entirely on your device. Your image never leaves your computer.
