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.
Does reducing file size always reduce dimensions?
No. Encoding changes are attempted first; dimension reduction is used when selected or needed for the target.
What is the best general workflow?
Remove unnecessary pixels when appropriate, then use a suitable format and moderate compression.
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.
