PNG to JPG Online — Fast Image Conversion

A screenshot PNG is huge. A photo exported as PNG is worse. JPEG is the usual fix — and JPEG cannot keep a hole in the background, so we paint white where alpha was.

JPEG is for pictures, not glass logos

If the PNG is a logo with a see-through canvas, flattening onto white is correct only when the site background is white. Dark themes will show a white box. Keep PNG for UI chrome; use this hub for photographs and screenshots of photographs.

Core Web Vitals vs brand marks

Hero photos almost always want JPEG. Icons and wordmarks almost always want PNG. Do not “optimize” a logo by destroying its edges.

Free versus folder

One still on Edge is free. A catalog dump uses VPS. We flatten every alpha the same way so a batch does not surprise you with black boxes.

After convert

If the JPEG is still too heavy, compress. If you needed the reverse, JPG to PNG will not restore alpha you flattened here.

How it works

  1. 1

    Drop the PNG

    One still is free on Edge. A catalog dump is Pro. Alpha will become white.

  2. 2

    We flatten, then encode JPEG

    Holes in the canvas cannot survive JPEG. White is the default composite so you do not get a black box surprise.

  3. 3

    Download and check the edges

    If the logo needed glass, you used the wrong hub. Photographs and screenshots of photographs belong here.
