A free no-upload image upscaler, and the three things it says it can't do

I had a few old, blurry photos I wanted to clean up, and no interest in signing up for accounts or uploading them to some server I don't know. Landed on ImgIng (imging.ai): open the page, pick the image, done. No login, nothing leaves the machine.

I'm not an engineer, I can't tell you how it works underneath, only how it felt. I tried it on a family photo — small original, 350×466, faded, with several crease-cracks across the face. Picked the "old-photo restoration" mode at 4x, and it ran locally in about 10 seconds, enlarging it to 1400×1864. The cracks faded, the faded tones came back, the fabric texture sharpened up. The whole time the image stayed on my device — the panel marks the work "local Worker".

What actually won me over was one detail: after the fix, the face was still the same face. It hadn't repainted the features into a "clearer person". The panel says so directly — it won't invent facial features, and a face too low-res to read can't have real information restored that was never there. I stared at that line for a bit, because it's refusing something a lot of people actively want: turn a blurry face sharp and specific.

That's the part worth repeating, because few tools say it this plainly. Upscaling is, at bottom, letting a model fill in what it guesses. Looking good is not the same as being right. So it prints three places you shouldn't use it: ID photos, forensic or historical verification, and OCR ground-truth. For sending to friends, wallpapers, making an old photo pleasant to look at — go ahead. But the moment the image has to prove "what the original looked like" — a receipt, a contract screenshot, identity papers — you don't use the upscaled version, you keep the original.

One practical note, since it threw me at first: the very first time you pick a tier there's a wait while the model downloads — these aren't small, tens to over a hundred MB. After that it's cached and near-instant. So the "slow first run" isn't the tool being sluggish, it's a one-time download; I nearly closed the tab before I figured that out.

So my take: as a no-login, no-upload "make it look nicer" tool, it's good. Just remember the three lines it drew for itself, and don't take its output into anything that needs the original as truth. And keep the original around either way — the upscaled copy is the disposable one, not the source.
