LumenFix — AI Photo Enhancer and Old Photo Restoration in the Browser

What is LumenFix?

LumenFix is a browser-based AI photo enhancement suite aimed at people who want to repair and improve existing photographs rather than generate new imagery. Its stated stance is restorative: the site declares "no face replacement, no new people in the frame," meaning enhancement is meant to recover detail that is already in the picture. The tool covers enhancement, upscaling, old-photo restoration, colorization of black-and-white prints, and a long tail of utilities such as an image extender, an AI image detector, SVG tracing, and a family of free format converters (WebP, PNG, JPG, AVIF, JFIF).

Everything runs in a desktop or mobile browser. There is no install, no mobile app, and no API; the paid tier is a subscription plus optional credit packs.

How LumenFix Works

The core workflow has three steps. First, upload a photo by dragging it in, clicking to browse, or pasting from the clipboard. Second, the AI processes the image — the site quotes roughly 27 to 30 seconds per job. Third, download the result, with a before/after slider available to compare the output against the original.

Credits meter the work. Standard enhancement, 2x upscaling, colorization, and restoration each cost 4 credits; text unblur costs 6. The free tier grants 10 credits per day and requires no account, with free exports delivered as watermark-free 2K JPGs capped at 2048 px. The Pro plan raises those ceilings: 4K and 8K output, original-size exports, and a 7-day download history. Free credits are valid only on the day they are issued.

Accepted inputs are JPEG, PNG, and WebP up to 15 MB; HEIC photos must be converted before upload. The locally running AI image detector downloads a model of about 45 MB and analyzes images without sending them to a server.

Main Features

• Multi-level enhancement — Standard (2x), Pro (finer detail and color), and Ultra HD (4K) enhancement modes for different source qualities.
• Upscaling to 8K — 2x, 4x, 4K, and 8K enlargement on Pro for print-sized output.
• Old-photo restoration — repair of scratches, creases, and tears, plus glare removal and text unblurring.
• Photo colorizer and restyler — colorize black-and-white photos or convert them into painting, sketch, coloring-page, and cartoon styles.
• Image extender — reframe photos to 1:1, 4:5, or 16:9 aspect ratios.
• Local AI image detector — a browser-run detector (about 45 MB model) that checks whether an image is AI-generated without uploading it.

Pricing

LumenFix uses a freemium credit model. The free tier provides 10 credits per day with no sign-up, enough for two standard enhancements (4 credits each), and exports are watermark-free 2K JPGs. Pro costs $15 per month or $90 per year and includes 400 monthly credits, with unused credits rolling over up to a balance of 1,200. Pro unlocks 4K/8K output, original-size exports, and 7-day download history. One-time credit packs are also sold, never expire, and stack with the Pro allowance. No per-pack prices are listed in the site copy reviewed.

Common Use Cases

• Family and vintage photo restoration — repairing scratches and faded prints, then colorizing black-and-white originals.
• Blurry screenshot and text recovery — unblurring UI captures and photographed documents.
• E-commerce product shots — recovering texture detail while the site notes branding and product features are not invented.
• Print preparation — upscaling low-resolution images toward 4K/8K for physical output.

Limitations

Input is restricted to JPEG, PNG, and WebP files up to 15 MB (one section of the site mentions 20 MB, so the exact ceiling is inconsistently stated), and HEIC must be converted first. The site itself cautions that heavy blur, severe compression, and low-light sources limit what enhancement can recover. Free credits expire the same day and free exports stop at 2048 px, so larger outputs require Pro. The image detector needs a roughly 45 MB local model download. There is no API, no mobile or desktop app, and no batch interface mentioned. Because it is restorative by design, users looking for generative face reconstruction or adding people to photos will not find that here.

Summary

LumenFix is a pragmatic photo-repair suite: a free daily credit allowance, watermark-free exports, concrete credit pricing, and a privacy posture that deletes uploads after 24 hours and runs the detector locally. Its restorative-only philosophy keeps results plausible at the cost of not offering generative tricks. For everyday blur, noise, restoration, and colorization jobs — especially vintage family photos — it is a low-commitment option; heavy-duty restoration or 8K output requires the Pro plan, and severely degraded sources may still exceed what any enhancer can recover.
