Everything About AI Image Denoising
Common questions about removing noise from photos with AI — answered clearly and directly.
1What is imgmend?
imgmend is a free online AI-powered image denoiser. It removes grain, noise, JPEG compression artifacts, and blur from digital photos in seconds — with no signup or software installation required. It uses Real-ESRGAN, a state-of-the-art deep learning model, to restore image quality.
2Is imgmend completely free?
Yes. imgmend is free to use with no account required. Free users can process up to 3 images per day. Downloads include a small watermark. The Pro plan ($9.99 one-time payment, not a subscription) removes the watermark and unlocks unlimited daily processing.
3Do I need to create an account to use imgmend?
No. You can upload a photo and download a denoised result without creating an account, entering an email, or providing any personal information. Simply go to imgmend.com, upload your photo, and download the result.
4What image formats does imgmend support?
imgmend supports JPG (JPEG), PNG, and WEBP image formats. The maximum file size is 10MB per image. For best results, upload the highest quality version of your original photo.
5What types of image problems can imgmend fix?
imgmend can fix: (1) grain and luminance noise from low-light or high-ISO photos, (2) chroma (color) noise from phone cameras, (3) JPEG compression artifacts — blocking, ringing, and mosquito noise, (4) blur and general image degradation, (5) degradation in old scanned photos.
6How does AI image denoising work?
imgmend uses Real-ESRGAN, a deep learning model trained on millions of clean/noisy image pairs. The AI has learned to distinguish between true image detail (edges, texture, fine lines) and noise (random variation that shouldn't be there). It removes the noise while reconstructing the real detail — far more effectively than traditional blur-based noise reduction.
7How long does processing take?
Most images are processed in 10–30 seconds, depending on the image size and current server load. Larger images (close to 10MB) may take up to 60 seconds.
8Can imgmend fix photos taken in low light?
Yes. Low-light noise is the most common use case. The AI specifically targets luminance noise and chroma noise caused by high ISO settings or dark environments, typically reducing visible grain by over 80% while preserving image sharpness.
9Can imgmend remove JPEG compression artifacts?
Yes. imgmend is effective at reducing JPEG compression artifacts including blocking (the visible 8×8 pixel grid), ringing around edges, and color banding in gradients. The AI reconstructs missing high-frequency detail that was discarded during compression.
10What is the difference between the Free and Pro plan?
Free plan: 3 images per day, watermark on downloaded images, no account needed. Pro plan ($9.99 one-time): unlimited images per day, no watermark, full HD quality download. The Pro plan is a single payment — not a recurring subscription.
11Are my uploaded photos stored or shared?
No. imgmend does not store your photos. Images are sent to the AI processing API in real time and discarded immediately after processing is complete. Your photos are never stored, shared, sold, or used for any other purpose. See our Privacy Policy for full details.
12What AI model does imgmend use?
imgmend uses Real-ESRGAN (Real Enhanced Super-Resolution Generative Adversarial Network), developed by Xintao Wang et al. Real-ESRGAN is widely regarded as the best general-purpose model for removing real-world image degradations. It is the same technology used in several professional image restoration tools.
13Can I use imgmend on my phone?
Yes. imgmend works in any modern web browser — on desktop, tablet, and mobile. No app download is required. The interface is mobile-responsive and touch-friendly.
14Does imgmend work on RAW files?
imgmend currently supports JPG, PNG, and WEBP formats. RAW files (.cr2, .nef, .arw, etc.) are not directly supported. For RAW files, export as a high-quality JPEG or TIFF (then convert to PNG) before uploading for best results.
15Will denoising make my photo blurry?
No — this is the key advantage of AI denoising over traditional methods. Old-school denoisers apply blur to reduce noise, which destroys sharpness. Real-ESRGAN removes noise while actively reconstructing sharp edges and fine texture. Results are clean and sharp, not soft or plastic-looking.
16Can imgmend upscale my image?
imgmend is primarily focused on noise removal and image quality restoration. The AI model may produce slight resolution enhancement as a side effect, but imgmend is not primarily an upscaling tool. For dedicated upscaling (2×, 4×), specialized tools like Topaz Gigapixel AI are better suited.
