What makes PNG special
PNG is a lossless format: it stores every pixel exactly and supports transparent backgrounds. That makes it the standard for screenshots, logos, icons, diagrams, text graphics and any picture you plan to edit several times. Designers, app stores, print shops and many forms ask for PNG for these reasons.
What happens when you convert
Your picture — JPG, WEBP, HEIC, AVIF, GIF, BMP, TIFF, SVG or ICO — is opened in your browser and saved as a PNG. Width, height and colours stay the same, and transparency in formats such as WEBP, GIF, SVG and ICO is kept. Several files can be converted at once and downloaded together.
What to expect from file size
Because PNG never throws detail away, photo files become larger — often several times larger than a JPG. For graphics with few colours, such as logos and screenshots, PNG is often small and very sharp. Animated GIFs and WEBPs become a still picture of the first frame.
Common problems and how to fix them
The PNG is too large to upload: use Compress Image with “Keep original format”, or use JPG for photos. The picture still looks blurry: PNG cannot restore detail lost in the original. SVG converts at a large size: small SVGs are drawn at least 1200 pixels wide for sharpness — use Resize Image if you need it smaller.
Good habits
Use PNG for graphics and editing, JPG or WEBP for sharing photos, and keep the original file before converting.
