Free Image Scaler

Get answers to common questions about image upscaling and using Free Image Scaler.

How does image upscaling work? +

Image upscaling uses interpolation algorithms to enlarge images while maintaining quality. Our tool applies real image enhancement filters to improve clarity, sharpness, and detail recovery during the upscaling process.

What image formats are supported? +

We support PNG, JPG, and WebP formats for input. You can export your upscaled images as PNG (lossless), JPG (smaller file), or WebP (best compression).

Is my image data private? +

Absolutely. All image processing happens directly in your browser. We never upload, store, or share your images. Your data stays 100% private and secure on your device.

What upscale factors are available? +

You can upscale images 2x, 4x, or 8x their original size. A 100x100 pixel image can become 800x800 pixels at 8x scaling. Higher quality results depend on your original image resolution.

What quality settings should I use? +

Start with default settings and adjust sliders gradually. Use moderate upscaling (2x-4x) for best results. Increase sharpness carefully to avoid artifacts. Experiment with denoise for noisy images.

Why does my upscaled image look blurry? +

Blurriness can happen if: (1) Your original image is very low resolution, (2) You're upscaling too much (try lower factors), or (3) Sharpness is too low. Increase sharpness and clarity sliders to improve definition.

Is there a file size limit? +

Yes, the maximum file size is 100MB. Most images are well below this limit. If needed, you can compress your image first or split it into smaller sections.
