Upscale images 2x or 4x using AI. Enhance clarity without blurring.
Upscale low-resolution images by 2x or 4x using an AI super-resolution model on a dedicated GPU. Produces sharp, detailed results far superior to traditional bicubic upscaling.

Resizing interpolates between pixels that already exist, so enlarging spreads the same information over a bigger canvas and looks soft. AI upscaling predicts detail — edges, texture, facial features — from patterns learned across millions of images, generating pixels that were never captured. That is why it looks sharp rather than merely bigger.
Small or low-resolution photos with real subjects: old family pictures, thumbnails you no longer have originals for, product shots, game screenshots. Images that are already large and sharp gain little. Heavily compressed JPGs improve but can also have their compression artefacts amplified along with the detail.
No — it is plausible reconstruction, not recovery. The model produces what a sharper version of that image would likely look like. For photos and artwork the result is usually convincing and useful. For anything evidential, such as reading a licence plate or verifying a document, treat the output as invented rather than factual.
Yes, AI Image Upscaler is completely free. No signup, no account, and no watermark on outputs. A Pro tier is available for 100 AI ops/day and larger file sizes.
AI Image Upscaler sends your file to our AI provider over an encrypted connection so the model can process it. It is deleted after processing and is not used to train models. If a file is confidential, use one of our in-browser tools instead, which never upload anything.

This tool uses a state-of-the-art AI super-resolution model. It is trained on millions of real-world degraded images, making it exceptional at restoring sharpness, texture, and detail from low-quality sources.
Why AI upscaling beats traditional methods: Traditional upscaling (bicubic, Lanczos) simply interpolates between pixels — it makes images larger but not sharper. The AI model was trained to reconstruct realistic high-frequency detail from scratch, producing results that look genuinely sharper, not just bigger.
Best use cases: Old family photos, low-resolution product images, website thumbnails, game screenshots, scanned documents, AI-generated art, and any image you want to print larger or display at full screen.
Privacy: Images are sent to a secure, private GPU server for processing and are never stored, logged, or shared. Each image is processed on demand and discarded immediately after.
