Input
Sets the mode of resizing the image. "Max" resizes the image to fit within the width and height, but will not increase the size of the image if it is smaller than width or height. "Crop" resizes the image to fill the width and height dimensions and crops any excess image data. "Scale" enforces the image width and height by scaling.
Lower values give better compression (at the cost of image quality)
Strip the image of any profiles, EXIF, and comments to reduce size
Correctly orient the image using the gravity sensor data stored in EXIF

What is an AVIF file?

An AVIF file is a modern image format that offers excellent compression and can be either lossy or lossless. It also supports transparency.

What is a PNG (Portable Network Graphics) file?

A PNG file uses lossless compression and supports transparency, making it ideal for logos, UI elements, and graphics with sharp edges. PNGs are typically larger than AVIFs but preserve exact pixels.

How to convert PNG to AVIF in simple steps

  • Open the Converter: Go to the TestMu AI PNG to AVIF Converter section.
  • Upload Your PNG Image: Drag and drop your PNG file into the upload area, or click to browse and select your image. (You can also paste an image directly.)
  • Resize (Optional): Under “Resize Output Image,” choose to keep the original size or set custom dimensions (width × height).
  • Adjust Fit Mode: In the “Fit” option, select how the image should adapt to the new size:
    • Max: fits within dimensions without stretching.
    • Crop: fills the size and crops the extra area.
    • Scale: stretches the image to match the width and height.
  • Set Quality (Optional): Enter a value between 1 and 100. Higher numbers give better quality but larger file size; lower values compress more and reduce size.
  • Additional Options:
    • Strip: Remove EXIF data, color profiles, and comments to reduce file size.
    • Auto Orient: Automatically rotates the image based on its EXIF orientation data.
  • Convert the Image: Click the Convert button to start the process.
  • Download Your AVIF: Once done, click Download to save the AVIF file.
