Each pair shows the same small area of a photo at the same zoom: on the left the original enlarged the usual way, on the right the AI-enhanced version. Results come straight from the tool on this page with no touch-ups; the example photos were generated with Visiojoy.

How to enhance an image with AI
Four steps, all on this page.
STEP 01
Upload your photo
Drop a JPG, PNG or WebP image into the tool above, or tap to choose one. Files up to 10 MB are supported.
STEP 02
Click Enhance Image
The AI upscales the photo to 2x its width and height and sharpens fine detail. A quick Google sign-in is needed the first time.
STEP 03
Compare before and after
Drag the slider over the result to see the difference. Zoom in on faces, text and textures where it matters most.
STEP 04
Download the enhanced image
Save the higher-resolution version. For an even bigger image, upload the result and enhance it again.
Why use our AI image enhancer
More pixels and crisper detail, without changing what your photo looks like.
2x resolution in one click
Every image comes back at 2x its width and height — 4x the pixels — so it holds up on large screens, in print and when cropped.
Sharper, crisper detail
Instead of simply stretching pixels, the AI rebuilds edges and fine texture, so the bigger image looks sharp rather than soft.
Keeps your photo's look
The enhancer adds resolution and clarity without repainting the image. Colors, faces and composition stay as they were.
12 free images to start
New accounts get 12 free credits and each image costs 1 credit, so your first 12 enhancements are free. Free results may carry a small watermark until your first purchase.
Free online image upscaler
Nothing to install. It works in any modern browser on desktop, iPhone and Android.
JPG, PNG and WebP
Upload images up to 10 MB, one at a time. The enhanced image comes back in the same format.
After your 12 free images, a credit pack from $9.90 covers about 640 more. See plans and credit packs.
Enhance AI art, product photos and more
Need a different fix? For blurry shots, use Unblur Image; to change lighting or colors, use the AI Image Editor.
Upscale images to 4K
Turn a 1080p screenshot, render or photo into a 4K image for big displays, wallpapers and presentations.
Enhance AI art and generated images
AI image generators often output around 1K. Enhance the result to get a version large enough for print, posters or high-resolution sharing.
Sharpen low-resolution product photos
Give small supplier photos and old catalog shots the resolution marketplaces and zoom-in galleries expect.
Enhance old and scanned photos
Give scanned prints and small old digital photos more resolution and crisper detail. It won't repair scratches, tears or faded colors — for those, describe the fix in the AI Image Editor.
Prepare photos for printing
Printing needs far more pixels than screens. Enhance a phone photo or web image before ordering prints, canvases or photo books.

AI image enhancer FAQ
What does an AI image enhancer do?+
It increases an image's resolution and sharpens fine detail. This enhancer upscales your photo to 2x its width and height and rebuilds edges and texture, so the bigger image looks crisp rather than stretched.
What's the difference between an AI image enhancer and an image upscaler?+
An image upscaler makes a picture bigger; an image enhancer makes it look better. This tool does both in one step: it upscales your photo to 2x and sharpens edges and texture, so you get a larger image that is also crisper. It doesn't change colors or lighting.
How much bigger will my image be?+
2x in each direction, which is 4x the pixels. For example, a 1,024 × 1,024 image becomes 2,048 × 2,048, and a 1,920 × 1,080 image becomes 3,840 × 2,160.
Can I upscale an image to 4K?+
Yes. A Full HD (1,920 × 1,080) image comes back at 3,840 × 2,160, which is 4K. For smaller images, download the result and run it through the enhancer again to reach 4x the original size.
Is the AI image enhancer free?+
Yes, to start. New accounts get 12 free credits and each image costs 1 credit, so you can enhance 12 images for free. After that, a credit pack from $9.90 covers about 640 images.
Do enhanced images have a watermark?+
Until your first purchase, results may include a small visiojoy.com watermark in the corner. After any subscription or credit pack purchase, new results are watermark-free and licensed for commercial use.
Can it fix a blurry photo?+
It sharpens detail, which helps with soft or low-resolution images. For photos blurred by missed focus, camera shake or low light, try Unblur Image, which is set up specifically for blurry shots.
Does it change colors, lighting or faces?+
No. It keeps your image as it is and only adds resolution and sharpness. To fix lighting, change colors or edit details, use the AI Image Editor and describe the change you want.
Which file types and sizes are supported?+
JPG, PNG and WebP images up to 10 MB. Transparent PNGs come back with a solid background, so if you need a cutout, enhance the image first and then remove the background.
Can I enhance photos on my phone?+
Yes. The enhancer works in mobile browsers on iPhone and Android — pick a photo from your camera roll and download the result straight to your phone.
Are my images private?+
Not by default. Results appear in Visiojoy's public gallery, together with the photo you uploaded. Subscribers can switch off Public Visibility before enhancing to keep the result private, or turn on Copy Protection to hide the original photo.
Do I need an account?+
You can pick a photo without signing in. When you click Enhance Image, a quick Google sign-in attaches the result and your free credits to your account.
Can I enhance many images at once?+
This page handles one image per run. For batches, the Visiojoy MCP server lets an AI assistant such as Claude or Cursor upscale a list of images for you, using the same credits.
Which AI model does this use?+
It currently uses Recraft Crisp Upscale, a model built to enlarge images while keeping edges crisp. Visiojoy is an independent platform and isn't affiliated with Recraft.
Can I use enhanced images commercially?+
Yes, once you've made a purchase. Images created after your first purchase (any subscription or credit pack) can be used commercially; images created before that are for personal, non-commercial use. Make sure you also have the rights to the original photo.
