How it works, what you get, limits
Làm gì
Convert among JPEG, PNG, WebP and AVIF. Batch allowed.
Cách dùng
Drop files to convert. JPEG gets a white background. AVIF depends on this browser.
Bạn nhận gì
Download converted images, or a ZIP. If HEIC cannot decode, export it in the OS first.
Tùy chọn và so sánh
Target format and quality. Failed AVIF encode is listed in the table.
WebP is often smaller than PNG for screenshots; old in-app browsers may still need JPEG.
Giới hạn
HEIC depends on the decoder. Failures show a reason instead of a blank preview.
FAQ
What happens to transparent PNG as JPEG?
A white background is added and alpha is dropped. Keep PNG or WebP for transparency.
Does AVIF always work?
It depends on this browser’s encoder. Failures are listed instead of a blank preview.
