Uses geometric step scaling for smooth results — avoids single-step pixelation artifacts that basic resizing causes.

FAQ
How does multi-pass upscaling work?
Instead of scaling in one step (which causes blurry or blocky results), the tool scales in small geometric increments using bilinear interpolation, then applies a sharpening pass at the end.
Will upscaling add more detail to my image?
No. Upscaling enlarges existing pixels — it cannot add detail that was not in the original. It produces a smoother large version suitable for printing or display.
What formats are supported?
PNG, JPG/JPEG, and WEBP. The download is always a PNG to preserve quality.
Is my image uploaded anywhere?
No. Everything runs in your browser using the Canvas API. Your images never leave your device.
