Image Compression Checker
Check an image’s file size, dimensions, format, compression ratio and optimization opportunity before deciding what to change.
Why use this tool?
- ✓ file-size analysis
- ✓ dimensions and megapixels
- ✓ format detection
- ✓ estimated reduction
- ✓ recommended next action
- ✓ browser-local analysis
Common use cases
- • diagnosing oversized files
- • pre-upload checks
- • website audits
- • choosing the next optimization
Diagnose the image before optimizing it
File size, dimensions and format answer different questions. A 5 MB image can still be too small for print, while a huge pixel image can be unnecessarily heavy for a website.
Use the analysis to identify the bottleneck first, then choose compression, resize or conversion as the next step.
- Compare dimensions with the actual display or upload requirement.
- Do not treat file size as a universal quality score.
- Preserve the source before making a delivery copy.

Privacy and file quality
Keep the original image as your master copy. Compression is a trade-off between file weight, dimensions, format and visual detail. MAXScanner shows the measurable result so you can make that choice from the output rather than a marketing score.
