FAQ

Is Scale-Max free to use?

Yes. Scale-Max is a free online image upscaler that runs directly in your browser.

Does upscaling reduce quality?

Upscaling creates new pixels. Scale-Max uses high-quality resampling plus optional enhancements (noise reduction, smoothing, sharpening, etc.) to keep results clean and detailed.

Can I batch upscale images?

Yes—upload up to 5 images at once. Images are processed sequentially for stability, and you can download individually or as a ZIP.

Can each batch image have a different crop ratio?

Yes. Click an image in the batch list, choose its crop/aspect preset (like 9:16 or 16:9), and Scale-Max will apply that crop to that file only.

Are my images uploaded to a server?

No. Images are processed locally in your browser for privacy. Nothing is uploaded.

What formats and quality options are available?

ScaleMax supports PNG and JPG/JPEG uploads, and you can export as PNG, JPG, or WebP with smart Auto quality defaults (recommended).
