About this tool

UAE Photo Compliance Checker — Will your photo be rejected?

ICA, Emirates ID, and MOHRE portals automatically reject photos that don't meet their biometric specifications. This free tool checks your photo against the exact requirements before you upload — so you don't lose time to a failed submission.

What does the checker verify?

The checker runs 10 automated tests: face detection, face size (55–85% of frame with hair), horizontal centering, eyes open, head tilt under 5 degrees, correct file format, file size under portal limit, minimum image dimensions, white background, and glasses detection. All checks run in your browser — your photo is never uploaded.

Which UAE portals does it check against?

The checker supports Emirates ID / ICA (200 KB limit), MOHRE worker photos (200 KB), UAE visa photos (200 KB), and MOHRE document uploads (500 KB).

About this tool

Secure Document Redactor — Hide sensitive information before sharing

UAE residents regularly need to share passport copies, Emirates ID scans, and visa documents with employers, landlords, property agents, and government services. This free browser-based redactor lets you black out passport numbers, ID numbers, dates of birth, and MRZ lines before sharing — so you share only what is necessary.

What information should I redact on my Emirates ID?

When sharing an Emirates ID copy with a landlord or employer, consider redacting your ID number, date of birth, and the MRZ lines on the back. Keep your name and photo visible for identity verification purposes.

Is blur redaction secure?

Black fill is more secure than blur. Blurred text can sometimes be partially recovered using image processing techniques. For maximum security, always use black fill over passport numbers, ID numbers, and MRZ lines.

Does this tool upload my documents?

No. All redaction is performed entirely inside your browser using the HTML5 Canvas API. Your documents are never sent to any server, stored anywhere, or seen by anyone. The tool works even without an internet connection once the page has loaded.

About this tool

AI Image Upscaler — Enlarge photos without losing quality

NexusCompress uses a Real-ESRGAN neural network to upscale images 2× or 4× with AI-reconstructed detail — not just stretched pixels. The entire process runs in your browser. Your photos are never uploaded to any server.

How is AI upscaling different from regular resizing?

Standard resizing (bicubic, Lanczos) simply interpolates between existing pixels, producing a larger but often blurry result. Real-ESRGAN uses a neural network trained on millions of image pairs to hallucinate realistic detail — reconstructing textures, sharpening edges, and reducing compression artifacts in the process.

What is the best use case for AI upscaling?

AI upscaling works best on photos, portraits, and natural images. It is particularly effective for rescuing old low-resolution photos, upscaling AI-generated images for print, enhancing product photos from suppliers, and improving scanned document clarity before portal uploads.

Does the upscaler work offline?

Once the AI model has been downloaded on first use (~5 MB), it is cached in your browser. All subsequent upscaling runs entirely offline — no internet connection is needed.

Frequently Asked Questions

How do I compress a JPEG without losing quality?

Use a quality setting between 75% and 85% for photos. If the image is only for the web, convert to WebP or AVIF — they often produce smaller files than JPEG at the same visual quality. See our JPEG compression guide for step-by-step settings. Use the before/after slider in NexusCompress to confirm details look acceptable before downloading.

Is it safe to upload my photos here?

Your photos are never uploaded. NexusCompress processes images entirely inside your browser using Web Workers and the OffscreenCanvas API. Files stay on your computer or phone; nothing is transmitted to our servers for compression. That makes it safe for sensitive screenshots, client work, and personal albums — as long as you trust your own device, your images remain local.

What is the best format to reduce image file size?

For most websites, WebP offers an excellent balance of quality and size (compare JPEG vs WebP). AVIF often achieves the smallest files where supported (AVIF vs WebP). Use JPEG for email; PNG for transparency.

Can I compress multiple images at once?

Yes. Drop multiple files or import an entire folder. NexusCompress queues each image, shows progress and savings per file, and lets you download everything as a single ZIP when you are done.

Does compressing remove EXIF or location data?

Re-encoding an image strips metadata such as GPS location, camera model, and timestamps. NexusCompress also corrects EXIF orientation so photos from phones display right-side up. This is ideal for privacy when sharing images online.

Is this tool really free?

Yes. Core compression is free with no account required. The tool runs in your browser, so there are no per-image API fees — only optional ads help support hosting.

What do you want to do?

NexusCompress — compress images. Instantly. Privately.
