Upscale Image 2x, 3x or 4x
Upscale image dimensions at 2×, 3× or 4× using smooth interpolation in your browser. This is conventional resizing: it adds pixels but does not recover missing detail or perform AI super-resolution. Preview the larger copy before saving.

Enlargement adds pixels rather than source detail
Image upscaling increases pixel dimensions. Klyvero offers 2x, 3x and 4x enlargement through smooth browser interpolation, with PNG output. It does not perform AI super-resolution or reconstruct missing texture. Because pixel count grows in both directions, a larger scale also increases memory requirements. Use a higher-resolution original when detailed enlargement is important.
Set custom image dimensions when a scale factor is less useful than a specific width or height.
How to use Upscale Image
Choose input
Open a JPG, PNG or other supported still image.
Review settings
Choose a 2×, 3× or 4× scale and apply the enlargement.
Save results
Inspect sharpness and output dimensions, then download the PNG.
Tips for Upscale Image
Use the best available source. Small text and compressed faces may remain soft after enlargement. Output is limited to 32 megapixels to keep browser memory manageable.
A 400 × 300 image at 2× becomes 800 × 600. Its dimensions increase, while the original amount of real detail remains the same.

Upscale Image: frequently asked questions
What to know before you go.
Is this an AI upscaler?
No. It uses high-quality browser interpolation and does not invent or recover detail.
How large can I upscale?
Choose 2×, 3× or 4× within the 32-megapixel output limit. Larger results are rejected before allocation.
Will the image become sharper?
Enlargement can look smoother, but missing detail remains missing. Check the preview at the size you plan to use.
Does PNG transparency remain?
Transparent areas remain in PNG output. Keep the original image for further edits.
What dimensions will a 400 by 300 image have at 4x?
The output becomes 1600 by 1200 pixels: both dimensions multiply by four. That creates sixteen times as many pixels, not sixteen times as much real detail. Inspect the preview because interpolation can leave small text and faces soft.
