Lossless with full transparency. The standard for screenshots, logos and UI graphics. Below is what PNG is best at, where it falls short, and how it compares — plus free, in-browser tools to convert PNG to and from other formats, with nothing uploaded.

PNG is a lossless format with full alpha transparency, designed in 1996 as the patent-free successor to GIF. It compresses flat colors, text and sharp edges perfectly, which makes it the standard for screenshots, logos, icons and UI graphics. The trade-off is size: a photo saved as PNG is often 5–10× larger than the same photo as JPEG. EditItAll optimizes PNGs losslessly, and can optionally reduce the color palette for much bigger savings.

Frequently asked questions

Is PNG lossy or lossless?+

PNG is lossless: it preserves every pixel exactly, with no quality loss.

Does PNG support transparency?+

Yes — PNG has an alpha channel, so it can store transparent areas. It is a still-image format (no animation).

Can browsers open PNG files directly?+

Yes — every mainstream browser displays PNG natively.

How do I open or convert a PNG file for free?+

Drop your PNG file into the EditItAll converter and choose an output format — it decodes and re-encodes entirely in your browser, with nothing uploaded, no account and no watermark.
