High-quality image upscaling using advanced interpolation algorithms with sharpening enhancement
Call this tool from your code in three languages.
# 1) Upload each file first → returns { filePath }
curl -X POST 'https://api.elysiatools.com/upload/image-quality-upscaler' \
-F 'file=@/path/to/imageFile.ext'
# 2) Call the tool with the returned filePath values
curl -X POST 'https://api.elysiatools.com/en/api/tools/image-quality-upscaler' \
-F 'imageFile=/path/to/file.ext' \
-F 'scale=2' \
-F 'targetWidth=0' \
-F 'targetHeight=0' \
-F 'maintainAspectRatio=true' \
-F 'interpolation=lanczos3' \
-F 'sharpenAmount=1.5' \
-F 'enhanceColors=true' \
-F 'outputFormat=jpeg' \
-F 'quality=92'Send a POST request with your inputs as JSON. File parameters require a separate upload first.
POST https://api.elysiatools.com/en/api/tools/image-quality-upscaler| Name | Type | Required | Description |
|---|---|---|---|
| imageFile | fileupload required | Yes | Supports JPG, PNG, WebP, BMP, TIFF and other common image formats |
| scale | select | No | Select scale factor (2x is recommended for best quality and details) |
| targetWidth | number | No | Set to use this width instead of scale factor |
| targetHeight | number | No | Set to use this height instead of scale factor |
| maintainAspectRatio | checkbox | No | Maintain the original image aspect ratio |
| interpolation | select | No | Lanczos3 provides best quality, Nearest is fastest |
| sharpenAmount | range | No | Enhance image details, higher values create stronger sharpening effect |
| enhanceColors | checkbox | No | Slightly enhance color saturation and brightness |
| outputFormat | select | No | JPEG for photos, PNG for images with transparency |
| quality | range | No | Output image quality (1-100), only for JPEG and WebP |
