Frequently Asked Questions

Everything you need to know about AI image upscaling

How does the AI Image Upscaler work?
Upload your image and choose your upscale settings. The tool uses advanced Canvas API interpolation combined with smart sharpening and enhancement algorithms to increase your image resolution while preserving detail. Choose from 7 AI modes optimized for different content types. All processing happens entirely in your browser — your images never leave your device.
What image formats are supported?
You can upload images in JPG, JPEG, PNG, WEBP, AVIF, and BMP formats. Output formats include PNG (recommended for transparency), JPEG, WEBP, and AVIF. PNG is best for images with transparency, while JPEG offers smaller file sizes for photographs.
What upscale factors are available?
You can upscale images by 2×, 4×, or 8× their original resolution, or use Custom Scale for any value between 1× and 8×. Higher upscale factors produce larger images but may require more processing time. For best results, we recommend starting with 2× and checking the preview before using higher factors.
What are the different AI modes?
Balanced — best for general use. High Detail — maximizes sharpness for textures. Photo — optimized for natural-looking photographs. Artwork — preserves brush strokes and artistic elements. Anime — smooth lines and clean edges for illustrated content. Illustration — enhances line art with crisp edges. Text Enhancement — maximizes text readability for screenshots and documents.
Can I upscale multiple images at once?
Currently, the tool processes one image at a time for maximum quality. You can reprocess the same image with different settings to compare results, or start over with a new image at any time.
What is the maximum file size?
The tool supports images up to 100 MB in size. For very large images, processing may take longer depending on the upscale factor and your device's capabilities. The interactive preview is optimized for smooth performance.
Is my privacy protected?
Absolutely. All image upscaling happens entirely in your browser using the Canvas API. Your images are never uploaded, copied, or transmitted to any server. No third-party services, no analytics tracking the content of your images, no data leaving your device.
How do I compare the original and upscaled results?
After processing, you can use the interactive before/after comparison slider to compare the original and upscaled images side by side. Drag the slider left and right to see the difference. You can also zoom and pan both images simultaneously for detailed comparison.

AI Upscaling Guide

Tips and best practices for upscaling images

What is AI Image Upscaling?

AI image upscaling uses advanced algorithms to increase image resolution while preserving or enhancing detail. Unlike traditional interpolation (which simply stretches pixels), smart upscaling analyzes the image content and applies targeted sharpening and enhancement to maintain quality at higher resolutions. The result is a larger image that looks crisp and detailed, not blurry or pixelated.

Choosing the Right AI Mode

Different content types benefit from different processing approaches. For photographs, the Photo mode applies gentle sharpening with noise reduction to maintain natural-looking results. For illustrations and anime, use modes that preserve line art smoothness. Text Enhancement mode maximizes contrast and edge definition for screenshots and documents. Experiment with different modes to find the best result for your specific image.

Understanding Upscale Factors

2× upscaling doubles both width and height (4× total pixels), 4× quadruples dimensions (16× total pixels), and 8× performs a full 64× pixel increase. Higher factors produce significantly larger output files. For web use, 2× is often sufficient. For print or detailed analysis, 4× or 8× may be appropriate. Consider your end use case when choosing the upscale factor.

Tips for Best Results

Start with a clean, high-quality source image — garbage in, garbage out. Use the Balanced mode first, then try specialized modes if needed. Adjust sharpening carefully: too much creates artifacts, too little produces soft results. Enable noise reduction for grainy or low-light photos. The interactive comparison slider is your best tool for fine-tuning settings before exporting.
