About the formats
PNG
PNG is a lossless format with full transparency support, ideal for screenshots, UI graphics, logos, and any image with sharp edges or text. The trade-off is size: photographic content stored as PNG is much larger than JPEG, WebP, or AVIF.
AVIF
AVIF is the newest mainstream image format, built on the AV1 video codec. It produces the smallest files of any widely supported format — often half the size of JPEG at the same quality — with transparency and HDR support. Encoding is slower, but the savings are significant.
Frequently asked questions
Are my PNG files uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly codecs — your files never leave your device. After the first visit the converter even works offline.
Can I convert many files at once?
Yes — add as many files (or whole folders) as you like, convert them in one batch, and download everything as a single ZIP. There are no file-count or size limits.
Will I lose quality converting PNG to AVIF?
You stay in control: AVIF quality is adjustable in the options panel, and the defaults are tuned to be visually indistinguishable for typical images. You can re-convert with different settings instantly.
