Frequently Asked Questions
Will compressing reduce image quality?
You control the quality slider. At 80% quality, most photos look identical while file size drops 60–80%.
Are my images uploaded to a server?
No — this is our key difference from TinyPNG and others. Compression runs entirely in your browser via the Canvas API.
What formats are supported?
JPG, PNG, and WebP input. Output is JPG or PNG, with optional resizing to exact dimensions.
Is there a file size limit?
No server means no server limits. Your browser memory is the only constraint — most images up to 50MB work fine.
