FAQ
About the Format converter
Is my image uploaded to a server?
No. Conversion, resizing, compression preview and file generation all happen in your current browser.
How can I reduce the exported file size?
Reduce the output dimensions first, then choose JPG or WebP and lower compression quality gradually. Actual size depends on the image and browser encoder.
Will changing export dimensions distort the image?
Aspect ratio is locked by default, so changing width or height calculates the other side automatically. A different ratio is used only after you turn the lock off.
