About the Image compressor
Modern formats such as WebP and AVIF store the same image in far fewer bytes than PNG or JPEG, which matters for web games and asset libraries. This tool re-encodes your image at a quality you choose and shows the before and after sizes so you can trade file size against visible quality.
How to use the Image compressor
- Drop an image in PNG, JPEG, WebP or AVIF.
- Choose the output format.
- Adjust the quality and compare the file sizes before and after.
- Download the compressed image.
Frequently asked questions
AVIF usually produces the smallest files at a given quality but encodes more slowly, while WebP is faster and very widely supported. For most game and web art either is a large saving over PNG or JPEG.
Lossy formats such as JPEG, WebP and AVIF discard some detail to save space, so the tool lets you pick a quality level and preview the result. PNG stays lossless.
No. Every image is compressed locally in your browser and nothing is sent to a server.
