Frequently asked questions
Are my images uploaded?
No. These image workflows process the selected file in your browser during the session.
Can I keep the original image?
Yes. The tools create an optimized copy; keep the original as your master file.
What quality should I use?
For many photographs, 80–85 is a useful starting range. The best value depends on the image and destination.
Continue your image workflow
After optimizing an image, use the next tool that matches the actual destination instead of processing the same file repeatedly.
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 resulting file size so you can make that choice from the actual output rather than an estimate.
