Undress AI

What is Undress.app?

Undress.app is a browser-based photo-to-nude AI tool that turns clothed images into undressed renders through several selectable modes. It positions itself as an “AI undressing” service for adult users, with support for male and female subjects and anime input. Compared to most competitors in the photo-to-nude category, Undress.app stands out on two fronts: an unusually short data-retention window (one hour to one day) and an explicit consent clause in its Terms of Service that prohibits generating images of non-consenting adults or minors, with stated enforcement actions including immediate account termination and reporting to authorities.

The product is delivered through a web interface; the footer references iOS and Android, though the public site doesn’t confirm native App Store releases. Beyond the web app, the service operates a Telegram support channel — a common pattern in this category for status updates and customer service.

Generation modes and feature set

Undress.app offers multiple “undressing modes” instead of a single generic setting. The current modes listed on the public site are Lingerie, Bikini, and NSFW, with the company referencing additional “more spicy” options. This tiered approach is useful for users who want a less-explicit output (Lingerie or Bikini) without going to full NSFW — a flexibility that not all competitors expose.

Beyond mode selection, the tool supports both male and female photos as input. Anime input is also supported, which broadens the audience beyond photo-realism use cases. The platform doesn’t disclose body type presets, pose libraries, or background controls on its public-facing site, so the per-mode customization depth isn’t externally verifiable.

For processing speed, Undress.app states outputs are returned “in a few seconds.” Real-world latency varies with server load and image complexity, and no benchmark numbers are published.

The platform is built around a token system: one token generates one image. Free credits are granted on signup (the exact count isn’t disclosed publicly). Paid token packs and access plans are sold separately — see the pricing section below.

Notably absent from the public feature list: video undress, batch processing, API access, and explicit watermark policies. If any of these matter to your use case, you’ll want to confirm them after signup before committing to a paid plan.

Output quality (per public claims)

Undress.app doesn’t publish output samples or benchmark comparisons on its homepage, so independent quality verification requires a paid test. The company’s marketing language emphasizes “high-quality” results from a model “trained on thousands of photos” — phrasing that doesn’t disclose whether the underlying architecture is a diffusion model, GAN, or hybrid pipeline. This level of technical opacity is standard in the category but worth noting.

Pro-tier (“Undress AI Pro”) outputs are advertised as “no blur” — implying free or lower-tier outputs may include some form of degradation, though the company doesn’t explicitly confirm whether this is censoring, low resolution, or both. Anime input is supported, but the platform doesn’t claim the same quality parity as photo input.

For edge cases — complex poses, multi-subject photos, unusual lighting, partial occlusion — Undress.app provides no public guidance. Photo-to-nude tools as a category struggle with these scenarios, and the absence of pose/lighting guidance suggests Undress.app is no exception. Best practice for any user testing the tool: start with frontal, well-lit, single-subject photos to validate baseline quality before processing more difficult inputs.

Privacy and data handling

Privacy is where Undress.app makes its most concrete commitments — and they’re stronger than the category norm. According to its privacy policy, uploaded photos and generated outputs are cleared from servers within one hour to a maximum of one day. The exact phrasing from the policy: “No media is stored on our servers. But to bring you the ‘result’ they go through a certain path one way or another, files are cleared from 1 hour to a maximum of 1 day.” This is one of the shorter retention windows we’ve documented in this category, where many competitors either don’t disclose retention at all or store generated outputs indefinitely in user accounts.

Signup is required and presented as a safety mechanism. The privacy policy frames signup as a check against misuse rather than a marketing capture, though all standard user data (email, payment, IP) is collected as a side effect.

Third-party data sharing is broader. The policy names IT providers, data storage, hosting, analytics, and payment processors as recipients, with Google Analytics specifically called out. Data may also be shared with affiliates, business partners, and legal authorities when required by subpoena or comparable demand. This is standard for SaaS but worth noting: short on-server retention doesn’t mean zero downstream propagation.

One gap: the policy does not document a self-service account deletion process. Users can request a download or correction of their personal data, but a documented “delete my account” button is absent from the public-facing policy. If this matters to you, you’d need to contact support directly and rely on manual workflow rather than a self-serve flow.

The privacy policy doesn’t state a minimum age for users — this is addressed in the Terms of Service instead (see the next section).

Pricing structure

Pricing on Undress.app uses a token model: one token equals one generated image. The free tier grants 3 credits on signup — a smaller starter allowance than several competitors in the category, where 5 to 20 free credits is the more common starting point. Users wanting to evaluate output quality before paying should plan around those 3 generations carefully.

Paid access is structured around access plans rather than recurring subscriptions. The Terms of Service confirm one-time purchases only with no auto-renewal — a friendlier model than most subscription-locked competitors. Per the Terms, the available plan durations are monthly, three-month, six-month, and annual access. Standalone token packs are also sold separately.

The monthly access plan is priced at $58.99. This is on the higher end for monthly photo-to-nude access in this category, where many competitors price entry-level monthly tiers between $10 and $30. The premium positioning likely reflects the longer-duration plans offering better per-image economics: users committing to 3-month, 6-month, or annual access can expect lower effective per-image cost, though exact USD pricing for those longer durations isn’t documented on the public-facing site.

Within each duration, tokens are bundled. The Terms specify that “purchased token packs don’t expire; plan-included tokens expire when access period ends” — meaning standalone token purchases carry over indefinitely, while plan-bundled tokens reset when the access window closes.

Exact USD pricing for non-monthly plans is not published on the public site (the public pricing URL returns a 404 at the time of writing). To see real prices for the 3-month, 6-month, or annual tiers, users must sign up and proceed to checkout. This pricing opacity for the longer plans is a meaningful negative against the tool’s overall transparency score and makes apples-to-apples cost-per-image comparison with competitors harder to perform.

Refund policy: refunds are available within 24 hours of purchase, provided fewer than 20 tokens have been used. This is an unusually concrete refund commitment for the category and a positive signal — most undress AI tools either offer no refunds or bury the refund window in fine print.

Ethics and consent terms

Among photo-to-nude AI tools, Undress.app’s Terms of Service stand out for being explicit on the most contested issue in the category — consent. The Terms include a direct prohibition: “You are forbidden from generating images of individuals without their explicit consent or individuals who are minors.” This is unusually direct language; many competitor tools either bury similar clauses in long ToS or omit them entirely.

Enforcement, as documented in the Terms, is two-tiered. For minor-content violations, the policy specifies immediate account termination and notification to authorities — not just suspension. For non-consenting adult imagery, the language is the same: account termination, with the broader threat of legal action.

The Terms also require users to meet a minimum age of 18 (or the age of majority in their jurisdiction, whichever is higher) and to be the consenting subject of any photos they upload or to have explicit permission from the depicted person.

How rigorously these terms are enforced — versus declared on paper — is structurally hard to verify externally. No tool in this category publishes enforcement statistics. But the existence of explicit, specific language in the ToS is itself a positive signal: it gives users a clear baseline to compare against and a written commitment that platforms with vaguer or absent consent language don’t provide.

For users prioritizing legally-defensible use of these tools, Undress.app’s documented consent posture is the strongest selling point in its public profile.

Who is Undress.app for?

Undress.app is best matched to users who:

• Want a documented privacy posture, with short server-side retention and explicit consent rules in writing, over feature breadth
• Prefer one-time access purchases without subscription auto-renewal
• Need mode flexibility (Lingerie / Bikini / NSFW / more) rather than a single generic output
• Use both photo and anime inputs

It’s a poor fit for users who:

• Need video undress (not supported)
• Need batch processing, API access, or technical integrations (no public mention of either)
• Want full pricing transparency before signup
• Need a self-service “delete my account” workflow

For more casual users testing the category, the free credit allowance is a low-friction way to evaluate output quality before committing — though confirming the exact free-credit count requires signup.
