ImgUpscaler

• Adjustable noise reduction

Choose a denoise strength from 0 to 1. The default is 0.5. Release the slider to enhance the original again with your chosen setting.

• Right-click to upscale

Right-click an image on a webpage and choose 2x or 4x. You can also choose a local file, drag and drop an image, or paste one from your clipboard.

• Side-by-side comparison

Open the original and enhanced image together in a new tab. Both appear at the same display size, with synchronized scrolling and zoom options for checking details.

• PNG downloads with transparency

Import PNG, JPEG, WebP, AVIF or GIF images and download the enhanced result as a PNG. Transparency is preserved; animated images use the first frame.

• Sidebar or popup

Choose how the extension opens. Follow the progress indicator, cancel a task, or enhance the image again. Keep the panel open while processing.

• Twelve interface languages

English, Simplified Chinese, Traditional Chinese, Japanese, Korean, German, French, Spanish, Italian, Vietnamese, Hindi and Portuguese (Brazil and Portugal). The interface follows your Chrome language, with English as the fallback.

HOW TO USE

1. Open the extension or right-click a webpage image. 2. Choose an image and select 2x or 4x. Enhancement starts automatically. 3. Adjust denoise if needed, compare the images, and download your PNG.

COMMON QUESTIONS

Are my images uploaded? Local enhancement runs in your browser. Webpage images are fetched from their original source when you grant access. Opening the official website does not automatically upload your current image.

Can this image upscaler process multiple images at once? The extension processes one image at a time. For batch processing and more advanced cloud enhancement, visit ImgUpscaler at https://imgupscaler.com/. Cloud processing requires uploading images on the website, and batch processing requires a paid plan.

What are the image limits? Input files can be up to 20 MB and 16 megapixels. Output is limited to 16 megapixels and 8,192 pixels on either side. Choose a smaller image or 2x if you reach the limit. Results and processing speed depend on the source image and your device; lost details may not be recovered.
