How do I compress an image online for free?

Drop your image into our Image Compressor, adjust the quality slider, and download the compressed result — all in your browser, no upload to any server.

Does compressing an image reduce quality?

JPEG compression is lossy, meaning some quality is traded for smaller file size. Our quality slider lets you control the balance. At 75-80% quality, the visual difference is barely noticeable.

Is my image uploaded to a server?

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

PNG files will be saved as JPG. PNG is lossless and cannot be compressed with a quality slider — converting to JPG achieves real file size reduction. Transparent areas will be filled white.
