About PNG
PNG
PNG (Portable Network Graphics) is a lossless raster image format that supports alpha-channel transparency. PNG is the standard choice for web graphics, logos, and UI elements where sharp edges and transparency matter, and it produces no loss in quality across saves.

Frequently Asked Questions
Is PNG a lossless format?▼
Yes. PNG compresses images without discarding any data, so converting to PNG preserves every pixel exactly — no quality loss, no matter how many times you re-save.
Does PNG support transparency?▼
Yes, PNG supports full alpha-channel transparency, which makes it the standard choice for logos, icons, and UI graphics that need to sit on any background.
Why is my PNG file so large?▼
PNG's lossless compression keeps all image data, which makes files larger than JPG for photos. For photographic images where transparency isn't needed, converting to JPG or WebP can shrink size dramatically.
Should I use PNG for website images?▼
PNG is great for logos, screenshots, and graphics with sharp edges or transparency. For photos on the web, WebP or AVIF usually deliver the same visual quality at a fraction of the size.
Will converting JPG to PNG improve quality?▼
No — conversion cannot restore detail that JPG already discarded. It does, however, give you a lossless file for further editing so no additional quality is lost from that point on.
