How to convert JPG to PNG

  1. 1

    Add the JPG

    Drop a .jpg or .jpeg file onto the page, or choose it from your device.

  2. 2

    Check the settings

    PNG is already selected. Change the dimensions if you need a different size.

  3. 3

    Convert and download

    Select Optimize image, then download your PNG.

When to use PNG

Choose PNG when a site or app only accepts PNG, or when you'll keep editing the image. PNG is lossless, so saving it again doesn't add new compression artifacts.

Why the PNG is larger

JPG stores photos compactly by discarding detail that's hard to see. PNG stores every pixel exactly, so the same photo saved as PNG is often several times larger.

Converting can't restore detail the JPG has already lost: the PNG looks the same as the JPG, not sharper.

If the PNG is too large, reduce its dimensions, or consider WebP, which keeps files much smaller.

Backgrounds stay as they are

JPG has no transparency, so the PNG has the same solid background as the original. PixMino converts formats; it doesn't remove backgrounds.

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

Will converting JPG to PNG improve quality?

No. The PNG is an exact copy of the JPG's pixels, including any compression artifacts. It only prevents further loss when you edit and save again.

Is JPEG the same as JPG?

Yes, they're two names for the same format. PixMino accepts both .jpg and .jpeg files.

Can I keep the PNG under a size limit?

Often only by reducing its dimensions, because a photo stored as PNG stays large. Set a limit and PixMino recommends dimensions that fit.
