PicPurify

PicPurify is a real-time image moderation API for services that need to detect and filter inappropriate user-submitted images. Its listed checks cover porn, suggestive nudity, gore, money, weapons, drugs, hate symbols, obscene gestures and QR codes. The API can also detect faces and return age-majority and gender classifications. It accepts JPG/JPEG, WEBP, PNG, BMP, TIFF, RAW, PDF, ICO and GIF files, up to 4096×4096 pixels or 16 MB. The image API limit is five requests per second; the maker says an increase can be requested for legitimate reasons. Each task performed on an image uses one unit, so running multiple checks consumes multiple units. PicPurify also provides a video API that analyzes frames individually, by default at one frame per second, with charges based on video size and frame interval. The maker says it can create a model for specific detection needs and provides integration examples for cURL, Python, Node.js and PHP. Its free allowance is 2,000 units with no time limit. Paid plans start at $19/mo.

PicPurify offers image checks, face classification and frame-based video analysis through an API. The free units have no time limit, while each task uses a unit and paid plans start at $19/mo.

It suits e-commerce sites, marketplaces, social networks, blogs, dating sites, parental-control products and safe browsers that need image or video moderation. Developers can integrate it into a website, app or service using the listed API examples.

Overview

PicPurify is a cloud service for screening user-submitted images, with video-frame analysis and face classification alongside its moderation API. It suits developers building upload checks into image-heavy products. Its lasting free allowance makes it approachable at low volume, while task-based units call for close usage planning as traffic grows.

Key features

Image moderation covers porn, suggestive nudity, gore, money, weapons, drugs, hate symbols, obscene gestures and QR codes. That breadth fits products where user uploads need screening, including marketplaces, social networks, dating sites, blogs, parental-control products and safe browsers. The focus is visual: PicPurify does not moderate text or audio.

Face detection can return age-majority and gender classifications, adding signals that may fit moderation workflows. Video analysis samples frames individually, with one frame per second as the default; both video size and frame interval affect usage. Teams can adjust sampling, but should budget video separately from still images.

The image API accepts JPG/JPEG, WEBP, PNG, BMP, TIFF, RAW, PDF, ICO and GIF files up to 4096×4096 pixels or 16 MB. Its five-request-per-second rate limit may be restrictive for upload bursts, though the maker accepts requests to raise it for legitimate reasons. Examples in cURL, Python, Node.js and PHP give developers practical integration starting points. Tailor-made models are offered for specific detection needs, making PicPurify more adaptable when standard checks are insufficient.

Pricing

The FREE plan costs nothing and includes 2,000 units with no time limit. Each task on each image consumes one unit, so applying several checks to one image spends several units. The free balance is useful for evaluation or modest workloads, but it is not a monthly allowance that replenishes.

STARTER costs $19 a month for 10,000 units / month, and PRO costs $49 a month for 30,000 units / month. Neither adds units by default, so they suit teams able to keep usage within a predictable monthly quota. ULTRA costs $99 a month for 70,000 units / month and charges $1.41 for 1000 units; MEGA costs $249 a month for 200,000 units / month and charges $1.25 for 1000 units; SUPRA costs $499 a month for 450,000 units / month and charges $1.11 for 1000 units. The lower per-unit rates at larger tiers favor sustained volume, while the smaller plans cap usage without automatic extra units.

The maker says there are no extra fees for account setup, onboarding, training or technical support. A free trial is also offered. Custom pricing is available for specific needs, including custom models; the maker invites customers to get in touch for pricing and support.

Platforms

PicPurify is offered through an API and web access, with cloud deployment. The image API's five-request-per-second limit is a planning constraint for bursty services, though the maker says it may be raised on request for legitimate reasons.

Who it's for

PicPurify is a strong fit for developers at marketplaces, social networks, dating sites and other services that need image checks integrated into an upload flow. Blogs, parental-control products and safe browsers are also among its intended uses. Teams that need text or audio screening should choose a broader moderation option; those processing video should estimate frame-based unit use before committing to a paid tier.

Pros and cons

• Pros: The 2,000 free units never expire, giving teams room to assess or handle light workloads without a recurring plan.
• Pros: A broad set of image checks, face classifications and frame-based video analysis serve several visual moderation workflows through one API.
• Pros: Multiple language examples and tailor-made models support integration and specialized detection needs.
• Cons: Multiple tasks on one image consume multiple units, so richer checks use quotas faster.
• Cons: Paid plans provide no extra units by default on STARTER and PRO, making over-quota usage something to plan around.
• Cons: No text or audio moderation is included, and the default video sampling interval means frame-based costs need their own estimate.

Verdict

PicPurify is best for developers who need image moderation, face classifications and frame-based video checks in a cloud API, and who can forecast task-based usage. Its no-expiry free units and wide set of visual checks make it easy to start; look elsewhere if your service needs text or audio moderation, or if its quotas and request rate do not suit your traffic.
