What Upscale Image helps you do

Enlarge images by 2, 3 or 4 times using the browser's high-quality smoothing. It makes a small image bigger without blocky nearest-neighbor steps, which is useful for thumbnails, proofs and quick enlargements. The output dimensions are exactly the source dimensions multiplied by the chosen factor.

Upscaling is done in your browser. No image data is sent to Haivix.

How it works

These tools decode the image in your browser, draw it onto a canvas, apply the change, and encode a new file. Nothing is uploaded, so the result depends on the browser's own decoders and encoders rather than a server library. Re-encoding always creates a new file: metadata such as EXIF, GPS and color profiles is generally dropped, and JPEG or WebP output loses a little quality on every save. Canvas work is capped at roughly 36 megapixels, so very large images may be refused rather than processed slowly. Browsers normally apply EXIF orientation when decoding, so a phone photo usually appears upright before any rotation is applied.

How to use Upscale Image

Open the images and choose the scale factor.
Run the batch and check the reported dimensions.
Inspect the result at 100 percent for softness or ringing.
Download the upscaled files.

When to use it

Enlarge a small logo or icon for a larger layout.
Prepare a low-resolution image for a larger display size.
Upscale a screenshot before using it in a document.
Create a larger proof from a small mockup.
Give a printer a bigger file when the source is small.
Make a thumbnail-sized image usable in a slide.

When not to use it

Do not expect new detail; this is interpolation, not AI reconstruction.
Do not upscale a blurry or heavily compressed image and expect it to look sharp.
Do not exceed the canvas limit with a very large source and a 4x factor.

Example

A 500 by 500 pixel image upscaled 2 times becomes 1000 by 1000 pixels. At 4 times it becomes 2000 by 2000, which is four times the area at each doubling. The result is smoother than a nearest-neighbor enlargement but still cannot invent texture that was never captured.

What you can do with Upscale Image

Upscale by 2, 3 or 4 times.
Apply smoothing with high quality.
Process several images in a batch.
Keep JPEG output for JPEG sources.
Download individually or as a ZIP.
Run the scaling locally in the browser.

Example: pick the format for the job, then check the result

Keep the original. Every tool downloads a new file, and repeated conversion between lossy formats compounds artifacts.

Choose the format by purpose: PNG for sharp edges, text and transparency; JPEG for photographs; WebP when file size matters on the web.

Check transparency before converting to JPEG. Alpha is flattened onto a background color, and the choice is permanent in the output.

Look at the output at 100 percent. Smoothing, sharpening and watermark placement are easier to judge at full size than in a small preview.

For a batch, check the ZIP contents and file count. A single failed image is reported separately and does not stop the rest.

Note the output dimensions and file size. A larger pixel count does not always mean a better result, and a large PNG can be slower to load than a smaller JPEG.

What to know before you start

This is interpolation, not AI upscaling, so it cannot invent detail that was not in the source.
Enlarging a blurry or compressed image also enlarges its artifacts.
Output size is capped by the browser canvas limit.
It does not sharpen or denoise the result.

Common mistakes

Using upscaling to rescue a blurry photo.
Choosing 4x on an already large file and hitting the pixel cap.
Assuming the file size grows in proportion to the dimensions.
Expecting transparency to survive a JPEG source.

Troubleshooting

If the tool refuses the job, the output would exceed the canvas pixel limit; use a smaller factor.

If the result looks soft, that is expected from interpolation.

If the output is JPEG for a PNG source, check the source type; the tool keeps JPEG and otherwise writes PNG.

If one file fails, the rest of the batch still completes.
