About Image Compressor
Reduce image file size with adjustable quality. Use it when you need the result without the overhead of opening a larger application. For anything important, compare the output with your source and keep the original until you are satisfied with the result.
Optimize for the destination, not the smallest number
A useful compressed image is one that meets the upload or performance goal without making important detail look damaged. Fine text, hair, gradients and sharp product edges show artifacts before broad areas of color do.
Start from the best source, resize if the dimensions are excessive, then lower quality gradually. Repeated lossy exports can accumulate visible damage, so keep the original as your master copy.
A realistic example
For an email attachment, try a moderate quality setting and compare at 100% zoom before pushing lower just to save a few extra kilobytes.
When this tool is not the right fit
If exact pixel preservation is required, use a lossless workflow instead of aggressive lossy compression.
What this tool does
An image compressor reduces image file size by re-encoding the image at a selected quality level.
Common use cases
- Reduce upload size
- Optimize website images
- Prepare images for email
- Save storage space
Limitations
- Lossy JPEG compression can reduce visual quality.
- Transparent PNG areas become a solid background when exported as JPEG.
