What this tool does
Image Compressor re-encodes images in the browser with quality and optional dimension controls, then shows size savings and preview.
How it works
Load an image, adjust quality and dimensions, preview the output, and download the compressed file. The image stays local.
Useful for
- Reducing upload size.
- Preparing web images.
- Compressing screenshots before sharing.
Limitations
Compression quality depends on the source image and format. PNG transparency and browser encoder support can affect output size.
Questions before the button mashing
Is the image uploaded?
No. Compression uses browser canvas APIs locally.
Why is a PNG sometimes larger?
Some images compress better as JPEG or WebP; PNG is not always the smallest format.
