PNG to JPG Converter
Convert PNG images to JPG format. JPG files are usually much smaller than PNG, so this is a good way to save space or speed up a page. Batch supported, runs in your browser.
PNG vs JPG: what changes
- For photos, JPG files are usually much smaller than PNG. Logos, screenshots and flat graphics shrink less, and their sharp edges can soften.
- PNG supports transparency but JPG does not, so any transparent areas are filled with a white background.
- JPG uses lossy compression, which trades a little quality for a smaller file. Raise the quality setting if you see blur around text or edges.

What happens to soft edges and shadows?
Before drawing your PNG, the converter paints the whole canvas white. Fully transparent areas therefore turn white, and partly transparent pixels are blended with white in proportion to their opacity. A black pixel at 50% opacity, for example, comes out as a mid grey of about 127, 127, 127. Anti-aliased logo edges, drop shadows and glows all become pale fringes.
On a white page or document those fringes are invisible. Put the same JPG on a dark or coloured background and a light halo appears around the shape. The fill is always white, with no setting for another colour, so for artwork that must sit on anything other than white, keep the PNG or use PNG to WebP Converter, which keeps the alpha channel.
When is JPG the wrong format for a PNG?
JPG compression was designed for photographs, where small errors hide in natural texture. Screenshots with small text, charts, diagrams and flat-colour logos fare worse: the encoder leaves faint smudges and ringing around sharp edges, and such images often compress well as PNG already. A text-heavy screenshot can come out only slightly smaller, or even larger, as a JPG.
PNGs that contain photos, such as edited pictures exported as PNG, are where the savings are largest: a 3.00 MB PNG photo that becomes a 1.00 MB JPG reads 67% smaller. Each card lists the old and new size and adds a percentage only when the JPG is smaller, so a card without one tells you the conversion did not save space.
Which JPG quality should you choose?
The slider runs from 50% to 100% and starts at 92%, a high setting. Every press of Convert to JPG re-encodes all loaded files from the original PNGs, so you can try 92%, check the sizes, then try 80% without losses piling up. Zoom in on text and thin lines when comparing, since those show compression first.
Converted files keep their names with the extension swapped: logo.final.png becomes logo.final.jpg. One file downloads directly, and a batch arrives as png-to-jpg-converted.zip. When a form demands a file under a fixed size, Compress Image to 200KB and Photo Resize to 20KB both aim for a set KB limit. Drag-and-drop accepts any image type, so a WebP dropped here also comes out as a JPG on white.
