# Upscale an Image by Percentage

URL: https://www.image-color-changer.com/upscale-image
Enlarge a PNG, JPG, WebP, or SVG by a percentage with smooth high-quality resampling. Aspect ratio stays locked. Free and runs in your browser.

### What upscaling by percentage really does
Scale by percent, not pixels: Typing exact pixel dimensions means working out the second number yourself, and getting it slightly wrong squashes the image. A percentage sidesteps that entirely: 150% multiplies both width and height by 1.5, so the proportions are mathematically guaranteed to hold.

Smooth resampling, not nearest-neighbour: Enlarging uses the browser's high-quality image smoothing, which interpolates between existing pixels rather than duplicating them into visible blocks. Edges and gradients stay smooth, which is the difference between an enlargement that looks intentional and one that looks like a mistake.

What upscaling can and cannot do: Enlarging cannot invent detail that was never captured. A 200 px logo scaled to 800 px will be smooth but softer than a native 800 px original — the information simply is not in the file. Upscaling is the right tool for meeting a minimum size requirement, not for rescuing a low-resolution photo.

Vectors are the exception: If your source is an SVG, it has no fixed resolution, so rendering it larger produces genuinely crisp output at any size. Whenever you have the vector version of a logo, upscale from that rather than from an exported PNG — the result is sharp rather than merely smooth.

Processed in your browser: The resize runs locally on canvas. Nothing is uploaded, so there is no queue, no file-size ceiling imposed by an upload limit, and no copy of your artwork sitting on someone else's server after you close the tab.

### How to upscale an image by percentage
1. Upload the image — Drop in a PNG, JPG, WebP, or SVG. It is read locally — nothing is sent to a server.
2. Set the percentage — Drag the scale slider anywhere from 110% to 400%. The preview updates as you move it.
3. Check the edges — Look at the preview at full size. If edges have gone soft, try starting from a larger original or the SVG.
4. Download — Save the enlarged image at full resolution as a PNG.

### When you need a bigger image
- Meeting a print minimum: A printer asks for larger dimensions than your export happens to be.
- Retina and 2x assets: Produce the @2x variant of an interface asset from the base size.
- Slides and posters: Fill a large slide or banner without the image sitting small in the middle.
- Stickers and merch: Print-on-demand services often reject files below a set pixel size.
- Marketplace requirements: Storefronts and app directories frequently enforce a minimum image size.

### Frequently asked questions
Q: Will upscaling make my image blurry?
A: Some softening is unavoidable — the extra pixels are interpolated from existing ones, not recovered from anywhere. Smooth resampling keeps it looking clean rather than blocky, but a large jump from a small original will visibly lose crispness. Modest increases hold up far better than extreme ones.

Q: Is this AI upscaling?
A: No, and we would rather say so plainly. This is high-quality interpolation, not a generative model inventing plausible detail. It is fast, predictable, free, and never changes what is actually in your image — but it will not reconstruct detail that was lost. If you need detail reconstructed — a small logo pushed to print size, or a soft photo sharpened — use the AI Image Upscaler instead. It costs credits because it runs a real model, and it is the right tool when interpolation is not enough.

Q: How much can I enlarge?
A: The slider goes to 400%, which quadruples both dimensions. Beyond roughly 200% from a small source, softness becomes noticeable on detailed images. Logos and flat graphics tolerate much more than photographs do.

Q: Does the aspect ratio change?
A: Never. A percentage scales width and height by the same factor, so proportions are preserved exactly. Nothing is cropped and nothing is stretched.

Q: What if I have the SVG?
A: Use it. A vector has no native resolution, so rendering it at a larger size gives genuinely sharp output rather than interpolated output. This is the single biggest quality difference available to you.

Q: What format do I get back?
A: A PNG at the new dimensions, which keeps transparency intact and avoids adding compression artefacts on top of an already-enlarged image.
