Compress Image to 500KB | MiniPx — Free, Fast & Private
Many content platforms, portfolio sites, and web applications limit image uploads to 500KB. This is a practical limit that balances image quality with page load speed. MiniPx makes it easy to hit this target while keeping images looking professional.
The most effective approach for photos is JPEG format with Smart preset and 1920px max width. This combination typically produces files of 150-500KB from any source image, with quality that looks excellent on any screen.
For larger photos that still exceed 500KB after Smart compression, reduce the max width to 1280px or switch to the Tiny preset. The file size decreases rapidly with dimension reduction — halving the width roughly quarters the file size.
500KB is generous enough that you rarely need to sacrifice visible quality. Even high-detail product photos and portfolio images look sharp at this file size with the right combination of format, compression, and dimensions.
MiniPx processes everything in your browser. Your portfolio images and professional photos are never uploaded to any server during compression.
