AVIF delivery optimization
AVIF Compressor
Create an AVIF copy from JPG, PNG or WebP and tune the output quality for web delivery. Compare the real result instead of assuming a codec change always saves bytes.
Magic format converter
Create a smaller AVIF delivery copy
Use JPG, PNG or WebP input, adjust AVIF output quality and inspect the finished image.
Higher quality usually creates a larger file. Compare the finished image instead of relying on the number alone.
The selected file is processed in your browser for this conversion. Keep the source when you may need another output later.
What actually changes the file size?
The codec and quality setting both matter, but image content matters too. A detailed photograph, a flat logo and a screenshot can produce very different results at the same slider value.
Inspect gradients, fine text and hard edges before accepting a smaller file.
AVIF compression versus a KB target
This workflow optimizes by quality. It does not promise a specific final byte count. If an application says “under 100KB” or “under 500KB,” use MAXScanner's exact target-size compressor instead.
Frequently asked questions
Is this the same as compressing an existing AVIF file?
This page creates a new AVIF delivery copy from JPG, PNG or WebP input and lets you control output quality. It is codec conversion plus compression, not lossless optimization of an existing AVIF bitstream.
What quality should I use for AVIF?
There is no universal best value. Start around the balanced range, inspect faces, gradients and text, and lower quality only if the destination still needs fewer bytes.
Will AVIF always reduce file size?
No. The result depends on the source image and browser encoder. Compare the actual output size with the original before deciding whether the conversion helped.
Can I use this for strict 100KB or 500KB limits?
A quality slider cannot guarantee an exact byte target. Use a dedicated target-size image compressor when a portal specifies a hard KB limit.
Why does AVIF encoding fail in some browsers?
Browser support for AVIF decoding and encoding is not identical. The tool reports an unsupported output instead of giving the wrong file type.
