Remini, PhotoApp, Snapseed and Lightroom compared — AI rebuilds of old faces versus honest sharpening and RAW editing, and when each is the right call.
Improving a weak photo means two genuinely different things. Adjustment tools work with the information already in the file: real contrast, sharpening and structure. AI enhancers do something more dramatic — they invent plausible detail where the file contains none, which is magic on a grandparent's scanned portrait and risky wherever accuracy matters. Knowing which process you are paying for is the whole game. The four apps in this guide pair two honest, traditional editors with two AI rebuilders, chosen so the decision between the truth and a convincing reconstruction is an informed one.
Remini rebuilds blurry, pixelated or scanned faces with startling results — remember it generates plausible detail rather than recovering the truth.
The AI is especially effective with faces, bringing apparent detail back to portraits scanned decades ago and sharpening low-resolution selfies, with no settings to fiddle with. The essential caveat: it rebuilds rather than recovers, filling in features the original never contained, so fine details may not match the real person. Free use is capped at very few enhancements per day, and ads plus subscription prompts are insistent. It is wonderful for family memories, not valid where accuracy matters.
Pros
Spectacular results on old portraits
Restores apparent detail in pixelated photos
Very easy to use, no settings to adjust
Cons
Invents detail instead of faithfully recovering it
PhotoApp packs several AI jobs into one app — sharpening, colourising black-and-white photos, object removal and upscaling — wider than Remini if slightly weaker.
Its edge over Remini is the range on offer in a single subscription: general sharpening, automatic colourisation of monochrome photos, removing unwanted objects from a background and increasing resolution. The trade-off is that each individual tool is a little less impressive than the category leader, particularly on faces. Free uses are capped low, and for occasional one-off jobs the subscription price is hard to justify, so it suits someone who expects to use several AI tools repeatedly.
Snapseed improves what is actually there — detail, structure, curves and selective edits — for free and without ads, inventing nothing.
Google's professional editor is the truthful option: structure and detail tools sharpen real edges, curves rescue contrast, and every edit stays non-destructive, so it is the right choice for a decent photo that needs a careful hand rather than a rebuild. Its weaknesses are familiar — the advanced tools take time to learn, there is no social or publishing layer, and no amount of structure editing can manufacture information missing from a genuinely pixelated file.
Lightroom edits colour and light to a professional standard with RAW support, so a photo that holds enough information improves without AI guesswork.
It offers precise control over exposure, colour, curves and profiles, one-tap presets for a consistent look and cross-device syncing, and RAW editing without quality loss. When the original exposure contains the detail, this is how enhancement should work. Premium features and cloud sync require an Adobe subscription, and it offers fewer creative AI toys than the dedicated rebuilders, so it appeals to photographers rather than photo restorers.
Pros
Professional colour and light editing
RAW support with no quality loss
One-tap presets for a consistent style
Cons
Premium features require an Adobe subscription
Fewer creative AI tools than Remini
Cloud sync needs a paid plan

Questions & answers
Does Remini restore a photo or invent it?
It rebuilds, which is not the same as restoring. The model has learned what human faces look like and fills in plausible detail the original never contained. The result is usually convincing, but fine features may not match the real person. For family memories it is wonderful; for any use where accuracy matters — evidence, documents, historical records — it is not valid.
What is the best free app to improve photo quality?
Snapseed, with no argument: free, ad-free and unlimited, with structure, detail and curves tools of professional grade. The AI apps are different because processing costs them server money, so Remini and PhotoApp both ration free use heavily. If the file is decent and only needs a careful edit, the free traditional editor is the better tool anyway.
Can a badly pixelated photo be recovered?
Only up to a point. If the information is not in the file, no tool can genuinely recover it; what AI apps do is generate coherent detail in its place. With a very small or heavily compressed picture the output is an interpretation, and in portraits it can subtly change the face. The better the original, the more faithful the result, so scan paper photos at high resolution before enhancing.
Can I colourise a black-and-white photo?
Yes. PhotoApp and similar AI tools do it automatically, and the results are often surprisingly believable on skin and landscapes. The colours are a statistical estimate, not the real ones: the app has no idea what colour the dress was. As a creative recreation it works very well; as a historical document it should never be presented as authentic.
