Frequently Asked Questions
How much can images be compressed?
JPEG images can typically be compressed by 50-80% with minimal visible quality loss. PNG compression varies — photos as PNG can shrink significantly, but already-optimized PNGs may only shrink 10-20%.
Does compression reduce image quality?
Lossy compression (JPEG) removes some data, but at 70-80% quality, the difference is imperceptible to the human eye. Lossless compression (PNG) reduces size without any quality loss.
What image formats are supported?
We support JPEG, PNG, WebP, and GIF. Each format has different compression characteristics and use cases.
Is there a file size limit?
No hard limit — it depends on your device's memory. Most devices can handle images up to 50-100MB easily.
Are my images uploaded to a server?
No. All compression happens locally in your browser using the Canvas API. Your images never leave your device. This is completely private and secure.
