Frequently asked questions
Are my images uploaded to a server?
No. Compression runs entirely in your browser using the Canvas API. Your files never leave your device, which makes this safe for private or client work.
Which formats are supported?
JPG/JPEG, PNG, and WebP as input. You can export to JPEG or WebP, which usually gives the best size-to-quality ratio.
How much smaller will my image get?
It depends on the source, but 40–80% reduction is common for photos at 70–80% quality with a modest resize. Use the live preview to find the sweet spot.
Will compressing reduce quality?
Lossy formats trade some detail for size. The quality slider lets you balance the two, and the before/after preview shows exactly what you'll get.
