Quick size bumps—not forensic reconstruction
You found a 200px logo raster but the deck template demands 800px. A lite upscaler avoids blocky nearest-neighbor stretch long enough for internal presentations—provided stakeholders know it is not print-ready photography.
Acceptable use cases
Enlarge favicons for wireframes, smooth pixel art for retro slides, or rescue a low-res screenshot for a bug ticket. Always keep the original file if a designer can recreate from source.
When to use real AI upscaling
Marketing hero photos, ecommerce zoom views, and archival restoration need dedicated models with GPU backends. Treat this browser demo as a convenience layer only.
