Frequently Asked Questions

What image formats are supported?

The tool supports JPEG, PNG, and WebP formats. JPEG and WebP support quality-based compression. PNG uses lossless compression by default.

What quality setting should I use?

80% quality is the recommended starting point — it typically reduces file size by 50–70% with minimal visible quality loss. For photos, 70–85% works well. For images with text or sharp edges, use 85–95%.

Does compression affect image quality permanently?

JPEG and WebP compression is lossy, meaning some quality is permanently reduced. PNG compression is lossless. Always keep your original files and compress copies.

Are my images uploaded to a server?

No. All compression happens directly in your browser using the Canvas API. Your images never leave your device.
