Frequently Asked Questions

CodBolt uses enhanced Bicubic interpolation combined with pixel structure analysis and edge reconstruction algorithms to enlarge your image while preserving sharpness and detail.

You can upscale by 2x, 3x, 4x, or enter a custom ratio. 2x doubles the dimensions — great for general use. 4x is ideal for very small images that need to be printed or displayed large.

Photo mode is optimized for photographs and realistic images. Illustration mode works better for art, drawings, and graphics with sharp lines and flat colors.

Noise Reduction (0–100) smooths out grain or artifacts in the upscaled result. Detail Boost (0–100) sharpens edges and fine textures. Start at defaults (20 and 30) and adjust to taste.

The tool supports images up to 20MB. Very large upscale ratios (like 4x on a big image) may take a moment to process since it runs in your browser.

No. All upscaling runs locally in your browser using Canvas API algorithms. Your image never leaves your device.
