AI Image Upscaler.
Turn a 1K draft into a print-ready 4K or 8K render. Zero artefacts, full detail.
Topaz AI-based upscaling — the same technology professional photographers and film restorers use. Real detail reconstruction, not naive interpolation.
Upscale an ImageReconstruct detail, not just pixels.
2×, 4×, or 6×
Target the resolution you actually need. 2× for screen, 4× for print, 6× when the source is already high-quality.
Detail reconstruction
Trained on millions of before-and-after pairs. Recovers skin texture, fabric weave, material grain that wasn't in the original.
Print-ready output
300 DPI at target size, no softness, no artefacts. Suitable for billboards, brochures, magazine spreads, large-format boards.
Print that looks professional.
Any image destined for billboard, poster, brochure, or magazine spread should be upscaled to at least 300 DPI at target size. A 1K image on an A1 board is visibly soft; a properly upscaled version prints crisp. Essential for pitch boards and client-facing print collateral.
Upscale an image
Rescue legacy work.
Got great renders from three years ago that look dated because they're 720p? AI upscaling can bring legacy work into the modern resolution expectation without redoing the render. Revive old portfolio pieces, archive work, and historical shoots for contemporary use.
Generate fast, upscale when needed.
Most AI image models run fastest at 1K or 2K. Generate at speed, then upscale only the images destined for formats that need high resolution. Keeps credit cost low while still delivering print-quality output when required.
