How to convert PNG to JPG

  1. 1

    Add the PNG

    Drop it onto the page or choose it from your device.

  2. 2

    Choose a background

    If the PNG has transparent areas, pick the colour that fills them. White is selected by default.

  3. 3

    Convert and download

    Select Optimize image, compare the result, and download your JPG.

What happens to transparency

JPG can't store transparency. When a PNG has transparent areas, PixMino fills them with a solid colour before converting: white by default, black, or any colour you pick.

The background option only appears when the image actually contains transparency.

Why JPG is usually smaller

For photos and images with gradients, JPG's lossy compression typically gives a much smaller file than PNG. Add a file size limit to go further: PixMino finds the highest quality that fits it.

When to keep PNG

Screenshots with small text, logos and flat graphics can show soft edges or faint blocks around sharp lines after JPG compression. Check with the comparison slider; if the edges matter, keep PNG or try WebP.

Supported formats

PixMino opens five formats and saves four. HEIC photos from iPhones are saved as JPG or PNG.

JPG

Best for
Photos and images with soft gradients.
Transparency
Not supported.
Compression
Lossy, with adjustable quality.

PNG

Best for
Screenshots, logos and graphics with sharp edges or text.
Transparency
Supported.
Compression
Lossless. Can use fewer colours where the change is invisible.

WebP

Best for
Websites that need small files.
Transparency
Supported.
Compression
Lossy, usually smaller than JPG at similar quality.

AVIF

Best for
The smallest photo files for modern websites.
Transparency
Supported.
Compression
Lossy, often smaller than WebP. Slower to create.

HEIC

Best for
Photos taken on iPhone and iPad. Opened by PixMino, saved as JPG or PNG.
Transparency
Not used by camera photos.
Compression
Lossy and very efficient, but poorly supported outside Apple devices.

AVIF and HEIC use codecs downloaded the first time you need them; after that they work offline. Animated images are converted as a single frame.

Questions

Can I choose the background colour?

Yes. When the PNG has transparent areas, the Format section offers white, black and a custom colour picker.

Will text in my screenshot stay sharp?

At high quality it usually stays readable, but JPG can soften sharp edges. Choose Best quality and compare before downloading.

Can I convert and keep it under 100 KB?

Yes. Choose 100 KB under File size limit before selecting Optimize image.
