About PNG files

PNG is a lossless image format. It keeps transparency and full color. People convert to PNG when they need every pixel unchanged or a transparent background. This hub converts HEIC, WebP, AVIF, JPG, SVG, and PDF files to PNG. It also converts PNG to JPG, WebP, ICO, and PDF.

People convert from PNG when they need a smaller file or a different format. JPG and WebP are smaller for photos. ICO is for favicons. PDF is for documents. People convert to PNG when a format is not supported or when they need a lossless copy. The converter runs in the browser and on our servers. Nothing to install. Uploads and downloads use HTTPS. No watermark.

How we convert PNG to other formats

PNG output

Lossless with compression level 9. Transparency is kept when the source has it. Full color is default. Palette reduction happens only if you turn it on.

Size

The original pixel size is kept by default. A resize only makes the image smaller, never larger, unless you change that option.

Transparency

PNG, WebP, and ICO output keep transparency. JPG output cannot keep transparency. With flatten on, transparent pixels get the background color you pick, and white is the default.

Quality

JPG and WebP output use quality 85 by default. WebP has a lossless option. PNG output is always lossless.

Documents

PDF to PNG renders at 300 DPI by default, with 72, 150, 300, and 600 DPI choices. PNG to PDF places the image on a page that matches the image by default, centered on white at 300 DPI.

Common problems and fixes

The PNG file is much larger than the source file.

PNG is lossless, so photos need many bytes. Use JPG or WebP for photos, or turn on palette reduction for simple graphics.

Transparency disappeared after converting to JPG.

JPG cannot be transparent. Keep the image as PNG, or convert to WebP, which supports transparency.

The output looks blurry or pixelated.

PNG is a pixel format. Start from a larger source. For SVG, set larger width and height values in the SVG file. For favicons, use a simple, bold version of your logo.
