Questions
Does this image compressor upload my image?
No. Compression runs directly in your browser with Canvas.
Why is my compressed image sometimes larger?
Very small or already optimized files can become larger after conversion. The size comparison tells you when that happens.
Which output format should I choose?
JPEG is usually good for photos, WebP can be smaller in modern browsers, and PNG is best when you need lossless output.
