Frequently Asked Questions
How much can I compress an image?
Most images can be reduced by 60–90% with little or no visible quality loss. JPEGs compress the most; PNGs with transparency typically compress less. Use the quality slider to find your sweet spot.
Does compressing an image reduce quality?
JPEG and WebP use lossy compression, meaning some data is discarded. At 70–85% quality the difference is usually invisible to the naked eye. PNG uses lossless compression so quality is always preserved.
Are my images uploaded to a server?
Never. All compression happens directly in your browser using the HTML5 Canvas API. Your images stay on your device at all times.
What image formats are supported?
You can upload JPG, PNG, WebP, and GIF files. You can output as JPG, PNG, or WebP. Converting to WebP typically produces the smallest file sizes.
Can I compress multiple images at once?
Yes — select or drop multiple files and they will all be compressed in one batch. Each image gets its own download link.
