Image Compressor: How to use
Reduce JPG or WebP file size, or work toward a chosen KB limit with a quality preview.
- Choose one or more supported images.
- Start with quality mode. Target-size mode searches for a quality that fits, and can reduce dimensions when you allow it.
- Process, inspect the result and download.
Use case and output checks
Compare a product photo at two quality settings using the same output format. Check fine text, gradients and actual file sizes rather than only the slider value. Target-size mode can reduce dimensions when allowed; preserve an original master because lossy encoding cannot restore discarded detail.
Supported files and limits
JPG, PNG, WebP input; JPG or WebP output
Compression is lossy. Target KB means 1,000 bytes per KB. If the target cannot be met, the tool reports it rather than claiming success.
Troubleshooting
Some images cannot reach a tight byte limit at the available quality without shrinking. Allow dimension reduction or choose a larger target, then inspect whether the resulting detail is still adequate.
