How this tool works

What it does

Image Upscaler increases pixel dimensions via canvas resampling.

Scale

Up to 4×, pixel-budget guarded.

Output

PNG/JPG/WebP with quality.

Honesty

Not neural super-resolution. Browser canvas export strips EXIF, GPS, and most other source metadata.

Image Upscaler in your browser

Image Upscaler increases an image’s pixel dimensions with browser canvas resampling. It is not neural super-resolution — it enlarges the pixels you already have, so it will not create detail that is missing from the source.

Pick a scale up to 4×, optionally sharpen, and choose the output format. PNG and WebP can preserve transparency when the source has an alpha channel and Background is set to Transparent; JPG output is flattened onto your chosen fill colour, with a quality control for JPG/WebP.

Image Upscaler shows the original and upscaled dimensions, the scale factor, the output format, and the file size. Browser canvas export strips EXIF, GPS, and most other source metadata. Animated GIFs are processed as a single still frame; animation is not preserved.

How to use Image Upscaler

  1. Upload your image into Image Upscaler — click, press Enter, or drag it in.
  2. Choose a scale factor (up to 4×) to enlarge the image.
  3. Turn sharpening on or off, then choose PNG, JPG, or WebP output.
  4. Click Process, then download the upscaled image.

Why use Image Upscaler

Scale up to 4×

Enlarge by a chosen factor.

Optional sharpen

Emphasise edges after scaling.

Honest limits

Resampling, not new detail.

Format choice

PNG/WebP can preserve transparency only when source alpha exists and Transparent background is selected; JPG flattens.

Common uses for Image Upscaler

Enlarge images

Reach a target pixel size.

Layout needs

Scale up before composing a design.

Minimum sizes

Meet upload or template minimums.

Format swap

Export larger as PNG, JPG, or WebP.

Frequently asked questions

Can Image Upscaler add detail that is not there?

No. Image Upscaler resamples existing pixels to a larger size; it is not neural super-resolution and cannot invent missing detail.

How far can Image Upscaler upscale?

Up to 4×, within a browser pixel budget. Results that would be too large show a clear error.

Does sharpening in Image Upscaler recover detail?

No. Sharpening only emphasises existing edges; it does not reconstruct lost detail.

Can I export Image Upscaler as PNG, JPG, or WebP?

Yes. Choose any of those or same-as-input, with a quality control for JPG/WebP.
