Free Image Downscaler

Downscaling reduces the pixel dimensions of your image (e.g. from 4000x3000 to 1000x750). Compression reduces file size by lowering quality without changing dimensions. For the smallest files, do both: downscale to the needed size, then use the Image Compressor.

No. Everything runs in your browser using the Canvas API. Your image never leaves your device.

Reducing dimensions always removes some pixel data. However, if your image was larger than needed (e.g. a 4000px photo for a 1000px display), downscaling will look indistinguishable from the original at its display size.

The downscaled image is saved as PNG to preserve quality. If you need a smaller file size, use the Image Compressor afterwards.
