Why use this tool
Image Compressor helps reduce image file size for websites, email attachments and everyday sharing. Choose a JPEG quality level and the browser re-encodes the selected image for download.
Compression is processed in the browser. The current tool exports JPEG, so transparent PNG areas may not behave like the original and repeated lossy compression can reduce visual quality. Keep the source file when quality matters.
How to use
- Choose an image from your device.
- Set JPEG quality from 0.1 to 1.0.
- Run Compress & Download.
- Compare the downloaded image visually with the original.
- Try a higher quality value if detail is too soft.
Use cases / examples
- Reduce photos before uploading to a website.
- Create lighter email attachments.
- Optimize large images for faster sharing.
- Test different JPEG quality levels before publishing.
FAQ
Is my image uploaded to a server?
The compression workflow runs in your browser.
Which format is downloaded?
The current compressor exports a JPEG file.
Does lower quality mean a smaller file?
Usually yes, though exact size depends on image content and browser encoding.
Will compression reduce image dimensions?
No. This tool changes JPEG quality; use Image Resize when you need different dimensions.
