How to actually get a good result out of these tools, and what is going on underneath them.

How to Remove a Background From an Image A practical guide to removing image backgrounds: how matting works, what makes a good input photo, how to spot a bad cutout, and when to fix it by hand instead. How to Upscale an Image How AI upscaling actually works, what it can and cannot recover, when to use 2x instead of 4x, and which images are worth upscaling at all. Honest about the limits. How to Restore an Old Photo A practical guide to restoring old family photos: scan properly, repair damage, colorize, then upscale. Free tools that run in your browser, so your scans are never uploaded. What WebGPU Means for Image Tools What WebGPU is, how much faster it actually is than WebAssembly, browser support in 2026, the 2 GB memory ceiling, and why running AI on your GPU changed what image tools can cost. The Transparent PNG Guide What an alpha channel actually is, why JPEG cannot store transparency, why your PNG background turns black, and when to use PNG vs WebP. A practical reference.
