How it works, what you get, limits
Що робить
Convert among JPEG, PNG, WebP and AVIF. Batch allowed.
Як користуватись
Drop files to convert. JPEG gets a white background. AVIF depends on this browser.
Що отримаєте
Download converted images, or a ZIP. If HEIC cannot decode, export it in the OS first.
Параметри й порівняння
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.
Обмеження
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.
