How to use the image compressor

  1. 1

    Add an image

    JPG, PNG, WebP, AVIF and HEIC files all work. Nothing is uploaded.

  2. 2

    Choose what matters

    Best quality keeps detail, Balanced suits most uses, Smallest file puts size first.

  3. 3

    Compare and download

    Drag the slider over the image to check detail, then download.

Three ways to compress

Each mode sets a starting quality and how low PixMino may go. Best quality stays at 92% for JPG and WebP unless you set a limit. Balanced uses 82%, which is hard to tell apart from the original at normal viewing sizes. Smallest file uses 65% and lets PNG use fewer colours whenever the image stays visually the same.

If you also set a size limit, the mode decides how far quality may drop before PixMino suggests smaller dimensions instead.

Which format compresses best

For photos, AVIF and WebP usually produce the smallest files, followed by JPG. PNG is the largest for photos but the best choice for screenshots, logos and flat graphics, where it keeps edges perfectly sharp.

PixMino keeps your image's format by default. Change it under Format if a smaller format is acceptable where you'll use the image.

  • Photo for a website: WebP or AVIF, Balanced.
  • Photo for an email or form: JPG, Balanced, with a size limit if one is given.
  • Screenshot with text: PNG, Smallest file.
  • Logo with transparency: PNG or WebP.

What compression can't do

Compression removes detail you are unlikely to notice; JPG, WebP and AVIF can't make a file smaller without any change at all. Re-compressing an already compressed JPG gains little and can add visible blocks. When the result would be larger than the original, PixMino tells you instead of pretending.

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

Is the compression lossless?

PNG output is lossless unless you choose Smallest file or set a limit that needs fewer colours. JPG, WebP and AVIF are lossy: they trade a little detail for much smaller files.

Why is my compressed file bigger than the original?

The original was already compressed more strongly than the mode you chose. Try Smallest file, set a size limit, or keep the original.

Does the compressor remove metadata?

Yes. The new file contains only the image: camera details, GPS location and other EXIF data aren't copied.
