Frequently asked questions
How much can I compress my images?
Typical compression ratios range from 50% to 90% file size reduction depending on the original image and quality settings. Photos often compress better than graphics.
Will compression reduce image quality?
With our quality controls, you can balance file size and quality. At 80% quality, most images look identical to the original while being significantly smaller.
Is the compression done on your servers?
No! Image compression happens entirely in your browser using the Canvas API. Your images never leave your device — maximum privacy.
Which format gives the best compression?
WebP typically provides the best compression ratio, followed by JPEG. PNG is lossless and produces larger files.
