What is an image compressor?
An image compressor reduces the file size of a photo or graphic so it loads faster on websites and takes less space in storage. The Spexo Image Compressor does this work inside your browser. Your file is processed locally and never sent to a server. Use the quality slider to control compression strength. Switch between JPG and PNG output. Check the file size savings before you download.How to compress an image with this tool
The flow is short. Most images compress in a couple of seconds.- Set the compression level. Move the quality slider between 10% and 100%. Lower values mean smaller files and a bit of visual loss. Higher values keep more detail at a larger size. 70% is a balanced starting point for most images.

Image Compressor vs compressing by hand
You can export compressed images from Photoshop or Figma. That works but it adds steps every time you need a quick result. The Spexo Image Compressor stays in your browser and gives you a quality slider with a clear size comparison. The compressor is the faster option for content creators, store owners and developers who want results without opening a separate app.Tips to get the best results
- Start at 70% quality and adjust from there. Most images look great at this level with a noticeable size reduction.
- Compare visually after download. If you see banding or blur, raise the slider and try again.
- Pick the right format for the image type. JPG works best for photos and PNG works best for graphics.
- Resize before compressing if the source image is very large. A 4000 pixel wide image on a 1200 pixel layout carries wasted file weight even after compression. Use the free Image Resizer to reduce dimensions first.
