Frequently Asked Questions

Does image compression affect quality?
Lossy compression (JPEG) slightly reduces quality to achieve smaller sizes. For most use cases, a quality setting of 70–85% is indistinguishable from the original to the human eye.
Is my image uploaded to a server?
No. All compression is performed locally in your browser using the Canvas API. Your images never leave your device.
What image formats are supported?
The compressor supports JPEG, PNG, and WebP formats. GIF and SVG are not supported for compression.
