Portrait detail
Aim for clearer eyes, hair, and facial features while keeping skin texture natural. Very small or heavily blurred faces may still need dedicated restoration.

What to inspect
See What AI Upscaling Changes
Compare the original and upscaled image at the same zoom. Look for cleaner edges, reduced pixelation, useful texture, and a natural appearance—not only a larger file.
Product edges and materials
Prepare sharper product assets for listings, ads, and design layouts. Check packaging text, logos, and fine patterns against the source.
AI art and illustration
Enlarge generated art, anime, and illustrations with cleaner-looking linework and smoother color transitions. Use the lowest level that meets your goal.
Posters and marketing graphics
Increase pixel dimensions for ads, posters, and campaign creative. Inspect small text, logos, product edges, and decorative elements before publishing.
How to Upscale an Image Online
Upload your image
Choose a JPG, PNG, or WebP file. Start with the largest, least-compressed source available.
Choose an upscale level
Select 2K for a balanced target or 4K when a larger layout, display, crop, or print workflow needs more pixels.
Review and download
Compare the result at 100% zoom, download the high-resolution image, or continue into another YuzuTime tool.
Make Low-Resolution Images Useful Again
Product photos for ecommerce
Prepare supplier photos, catalog crops, and older product assets for listings, marketplace thumbnails, ads, and fresh layouts.
Portraits and personal photos
Improve small portraits, profile photos, and family images before sharing, displaying, or placing them in a creative project.
AI art, anime, and illustrations
Prepare generated and illustrated artwork for wallpapers, portfolios, print mockups, or higher-resolution editing.
Social posts, thumbnails, and ads
Turn soft or compressed visuals into more usable assets for social feeds, thumbnails, banners, decks, and campaign creative.
Print and large displays
Increase pixel dimensions before using an image in a poster, flyer, slide deck, or display. Confirm final size and PPI before production.
Upscale Level
Choose a 2K or 4K Output
2K
Choose 2K when the original is reasonably clear or you need a balanced output for web, social media, presentations, and moderate layouts.
4K
Choose 4K when a display, crop, print, or large layout needs more pixels. 4K commonly means 3840 × 2160 for 16:9 media, but exact output depends on aspect ratio and service limits.
A 4K file is not automatically sharp or accurate. Source quality, compression, subject matter, aspect ratio, and the final model all affect the result.
Get Better Upscaling Results
Start with the largest, least-compressed version of the image you can find.
Choose 2K before 4K when a face, logo, or small text must stay close to the original.
Compare at 100% zoom and inspect edges, eyes, fingers, lettering, and repeating patterns.
Use the original vector file for logos and text-heavy graphics whenever it is available.
For transparent PNGs, check the alpha channel around hair, fur, glass, and soft shadows.
Treat AI-created detail as a plausible reconstruction, not recovered ground truth.
Clear Limits Before Processing
Upload one JPG, PNG, or WebP image and choose 2K or 4K. Anonymous visitors receive one free 2K upscale per day. Signed-in 2K requests cost 2 credits; 4K costs 4 credits and requires purchase history. Processing results vary with source quality, subject matter, compression, and fine detail.

FAQ
AI Image Upscaler FAQ
What is an AI image upscaler?
An AI image upscaler increases pixel dimensions while using a trained model to reconstruct cleaner-looking edges, textures, and patterns. This can look more natural than simply stretching the original pixels.
How do I upscale an image online?
Upload a supported image, choose the 2K or 4K Upscale Level, start processing, inspect the result against the original, and download the higher-resolution file.
Should I choose 2K or 4K?
Use 2K for a moderate output target and when preserving the original appearance matters most. Choose 4K when a larger layout, crop, display, or print workflow needs more pixels.
Can I upscale an image to 4K?
Yes. Choose the 4K Upscale Level after signing in with an account that has previously purchased credits. Exact output dimensions depend on the source aspect ratio and model behavior.
Does AI upscaling fix blurry or pixelated images?
It can reduce the visible effects of low resolution, compression, and mild blur, but it cannot recover exact detail that was never captured. Severe blur or text damage may need restoration.
Which image formats are supported?
The uploader accepts JPG, PNG, and WebP images. Use the largest, least-compressed source available for the best starting point.
Can I upscale product photos, portraits, anime, and AI art?
These are common upscaling use cases. Results vary with source quality, so check fine edges, faces, text, logos, and repeating patterns before publishing.
Is the AI image upscaler free?
Anonymous visitors can complete one free 2K upscale per day. Signed-in 2K requests cost 2 credits, while 4K requests cost 4 credits and require an account with purchase history.
Are my uploaded images private?
Files are sent only to provide the requested upscaling job. Review the current Privacy Policy for retention and data-handling details before uploading sensitive content.
Can I use an upscaled image commercially?
Commercial use depends on your rights to the original and YuzuTime’s terms. Upscaling does not grant ownership of content you do not have permission to use.
Prepare Your Image for Upscaling
Upload a photo, product image, portrait, illustration, or AI-generated image, then choose the 2K or 4K output level you plan to use.
