How it works
How to upscale an image online
Choose how many times larger the image should be. Zareviko shows the expected pixel dimensions before generation and preserves the source aspect ratio.
- 1
Upload the source
Add one JPEG, PNG, or WebP image up to 10 MiB.
- 2
Choose 2× or 4×
Select the enlargement multiplier and review the estimated output dimensions.
- 3
Upscale with AI
Start the upscale after reviewing the quote.
- 4
Compare and download
Compare the original and upscaled result, then save it in your preferred supported format.
Why it helps
Upscale images without simple pixel stretching
An AI image upscaler uses super-resolution technology to reconstruct plausible edges and details while producing an image that is exactly 2× or 4× wider and taller.
Exact multiplier
Choose 2× or 4× and see the expected output width and height before processing.
Aspect ratio preserved
Both dimensions grow by the same multiplier without stretching the original composition.
Format control
Keep the source format or export a supported JPG, PNG, or WebP file.
Use cases
When should you upscale an image?
Ecommerce product images
Create larger storefront assets for product pages, marketplaces, and campaign layouts.
AI-generated images
Prepare a larger working file before cropping, compositing, or adding typography.
Social media and presentations
Increase pixel dimensions for high-density screens and larger slide layouts.
Print preparation
Produce a larger source file before checking the final physical size and print resolution.
Old web images
Turn an undersized but usable web image into a larger working copy.
Know the limits
What upscaling cannot invent
- 1Very blurred faces or text may remain ambiguous.
- 2The output follows the source composition and aspect ratio.
- 3Maximum input size is 10 MiB; supported formats are JPEG, PNG, and WebP.
FAQ
Image upscaling, explained
What does an AI image upscaler do?+
An AI image upscaler increases an image's pixel dimensions and uses AI super-resolution techniques to reconstruct edges and plausible visual detail.
What's the difference between 2× and 4× upscaling?+
2× doubles the width and height, while 4× multiplies both dimensions by four. An 800 × 600 image becomes 1600 × 1200 at 2× or 3200 × 2400 at 4×.
Does upscaling improve image quality?+
AI upscaling can make a low-resolution image look sharper at a larger size, but it cannot reliably recover information that is completely missing from the original.
What image formats are supported?+
JPG, JPEG, PNG and WebP.
Will upscaling change the aspect ratio?+
No. Standard 2× and 4× upscaling keeps the original aspect ratio.
Is Image Upscaler the same as Image Enhancer?+
No. Image Upscaler focuses on increasing resolution. Image Enhancer focuses on blur, noise, poor lighting or damaged details.
