Best AI Image Upscaler Tools

Deep Image is a cloud-based AI image enhancement platform that upscales photos up to 300 megapixels using generative upscale technology, which can restore missing detail in degraded or low-quality images. Beyond upscaling, it offers noise and artifact removal, sharpening, face-detail enhancement, and automatic color and lighting correction. The platform also includes background removal and generation, AI image generation from text prompts, face swap, avatar creation, virtual staging, document upscaling, and inpainting/uncrop tools.

It is aimed at e-commerce sellers, real estate professionals, print businesses, photographers, and content creators who need to enhance product or property photos at scale. Deep Image is accessible through a web app and a full API, with every website feature also available via API. Pricing is credit-based, with pay-as-you-go credit packs and monthly or yearly subscription tiers, plus a custom enterprise option for high-volume users.

Waifu2x is a free, open-source single-image super-resolution tool built on deep convolutional neural networks. It was originally created to enlarge anime-style illustrations while reducing noise and preserving line quality, and it also supports photographic images. The web version at waifu2x.net lets users upload an image, choose an upscaling factor (1.6x or 2x on the standard site) and a noise-reduction level, and download the result as PNG or WebP.

The project is maintained as open source on GitHub (nagadomi/waifu2x), and the technique has been reimplemented in numerous third-party ports (Caffe, NCNN-Vulkan, TensorRT, Converter-CPP) for local desktop use without file-size limits. The hosted web demo imposes practical limits (around 5MB per file, up to 3000x3000px for noise reduction and 1500x1500px for upscaling) and offers an experimental in-browser "unlimited" version with 4x upscaling. There are no paid subscription tiers; the project accepts optional support via Patreon and Fantia.

AI Image Enlarger, built by Imglarger, is a browser-based AI photo enhancement suite that upscales images by 2x, 4x, or up to 8x while rebuilding detail, edges, and textures instead of simply stretching pixels. It supports JPG, PNG, and WebP formats and includes complementary tools such as an AI photo enhancer for blurry or low-quality images, background removal, face retouching, anime and illustration upscaling, black-and-white photo colorization, and an AI uncrop/extender for expanding image backgrounds and aspect ratios.

The tool runs entirely online with no installation required, and offers a free tier alongside paid subscription plans with batch processing and higher-resolution limits. Uploaded and processed images are automatically deleted after a set retention window, and results are delivered without watermarks. A companion mobile app (PhotoAI) is also available for iPhone. The service targets casual users, photographers, e-commerce sellers, and designers who need quick image upscaling and restoration without professional editing software.

Smart Upscaler by Icons8 is an AI image upscaling tool that increases image resolution using deep learning trained on millions of images. It automatically performs sharpening, noise reduction, and color correction alongside resolution enhancement, and includes a dedicated face enhancement mode designed to produce natural-looking portrait results. Images can be upscaled up to 7680x7680 pixels, and the tool supports JPG, PNG, and WebP files up to 5MB each.

The tool is available as a web app with batch processing for up to 500 images at once, and an API for developers who want to integrate upscaling into their own applications or workflows. Free users can upscale a limited number of images with a watermark applied to results. Paid prepaid packs and subscription plans remove the watermark and increase or remove monthly image limits.

Nero AI Image Upscaler is an online and desktop tool that enlarges and enhances photos using deep convolutional neural network models. It can upscale images up to 800% (up to roughly 16K-32K resolution and as large as 268 to 1024 megapixels), while sharpening detail, removing noise and JPEG compression artifacts, and restoring old or damaged photos. Users can choose between enhancement styles such as Standard, Photograph, Face, Anime, and Reconstruct depending on the source image.

The product is offered as a free web tool with limited daily credits, a paid Nero Credits subscription (Pro Pass) for higher volume and batch processing, and a separate paid desktop application for Windows and Mac with a one-time or annual license. It supports common formats like JPEG, PNG, and TIFF, offers batch processing of multiple images at once, and is built by Nero AG, a long-standing German software company known for its Nero Platinum and video/photo tools.

VanceAI Image Upscaler is a web-based AI image enlargement tool that increases image resolution by 2x, 4x, or 8x (up to 40x combined with other tools) while aiming to preserve detail and sharpness. It uses Generative Adversarial Network (GAN) based models trained on large photo datasets, with specialized processing for portraits, landscapes, anime, illustrations, and text so edges and textures are reconstructed rather than simply stretched. The tool runs in any browser for single images and is also available as a Windows/Mac desktop app for batch processing of large volumes without file size limits.

Beyond upscaling, VanceAI's platform bundles related image tools such as denoising, sharpening, background removal, and photo restoration under the same credit system, so a subscription unlocks the wider suite rather than the upscaler alone. Pricing is credit-based with monthly or annual subscription tiers plus a pay-as-you-go option, and non-subscribers get a small number of free monthly credits to try the service. Paid plans remove watermarks, raise the upload size limit to 10MB/34MP, and add background processing and priority support.

Bigjpg is an AI-powered image upscaling tool that uses deep convolutional neural networks to enlarge images without the quality loss typical of traditional resizing. It offers two specialized modes: an art mode tuned for anime, illustrations, and line art, and a photo mode for natural images with gradients and textures. Users can enlarge images up to 16x and adjust noise reduction levels (none, low, medium, high, highest) to control artifact removal during upscaling.

The service is browser-based and requires no installation, with additional apps available for Windows, Mac, iOS, and Android, plus an offline enlarging option. A REST API is offered for developers who want to integrate the upscaling engine into their own workflows. Bigjpg has a free tier for casual use and paid plans that raise monthly image limits, upload size caps, and processing speed, with priority servers and batch processing for paid subscribers.

Let's Enhance is a cloud-based AI image enhancement platform that upscales, sharpens, and restores photos.
