What is a .png file?

PNG keeps every pixel exactly and supports transparency, which makes it right for logos, screenshots, diagrams and anything with sharp edges. The price is size: a photo saved as PNG is often several times larger than the same photo as JPG.

People convert PNGs to JPG or WebP to shrink them for email and websites, and to PDF for documents. When the PNG has a transparent background, converting to JPG needs a replacement colour, since JPG cannot hold transparency.

How to convert a PNG and handle transparency

Drop the PNG, choose the output, and if it is transparent a background control appears so you can pick white, black or any colour. WebP output keeps transparency if you need it and still shrinks the file.

  1. Drop your PNG files below.
  2. Choose JPG, WebP or PDF. If the PNG is transparent, pick the background colour.
  3. Press Convert and download.

PNG questions

Why does my PNG turn black or white when converted to JPG?

JPG cannot store transparency, so transparent pixels need a colour. This tool lets you choose it (white by default) instead of silently using black.

How do I make a PNG smaller?

Convert to WebP or JPG, or use a size preset to reduce the pixel dimensions. For photos, JPG or WebP is far smaller.

Will a PNG converted to WebP keep transparency?

Yes. WebP supports transparency.

Is PNG better than JPG?

For graphics and text, yes. For photographs, JPG gives much smaller files with little visible difference.

Is it safe to convert a PNG online?

Here nothing leaves your device. The conversion runs in the browser.
