FAQ
PNG to WebP questions
Are my PNG files uploaded to ImgKit?
No. This converter uses browser APIs, so files are decoded and exported on your device.
Does WebP keep PNG transparency?
Modern browser WebP encoders support alpha transparency. Always preview transparent graphics before replacing production files.
Why is my WebP file bigger than the PNG?
Small icons, flat artwork, or heavily optimized PNG files can already be compact. WebP usually helps most with photos, screenshots, and large graphics.
