Frequently Asked Questions
How do I upscale an image online for free?
Drop your image into the Upscale tool, choose 2×, 4×, or 8× enlargement, and click Upscale. The enlarged image downloads instantly.
What upscale factors are available?
2× (doubles the width and height), 4× (quadruples dimensions), and 8× (eight times the original size). Choose based on your target resolution.
Will the upscaled image look blurry?
The tool uses a high-quality Lanczos/bicubic interpolation algorithm that produces sharper results than basic nearest-neighbour scaling, though upscaling always involves some interpolation. For best results, start with the highest-resolution source available.
When should I use upscaling?
Use upscaling when you need a larger version for printing, when a low-res image needs to fill a larger canvas, or when preparing images for high-DPI displays.
Is my image uploaded to any AI server for upscaling?
No. This is a browser-based interpolation upscaler — everything runs locally in your browser. No upload, no AI cloud service, complete privacy.
