AI Image Upscaler API: Upscale & Enhance Photos 4x

Turn small, blurry or heavily compressed images into crisp, high-resolution pictures. Paste image links, choose 2x or 4x, and get the upscaled files in PNG, JPG or WebP, ready to download.

Powered by Real-ESRGAN, the open-source AI model behind popular desktop upscalers. No GPU, no software to install, no subscription: pay per image.

Why this one?

• 4x more pixels, real detail. The AI rebuilds edges and textures instead of just stretching the image.
• Bulk. Upscale hundreds of images in one run, straight from their URLs.
• Your format. Lossless PNG (keeps transparency), or light JPG / WebP with the quality you choose.
• Predictable cost. Very large inputs are scaled to a safe size first, so a run never surprises you.
• A pay-as-you-go alternative to Topaz Gigapixel, Upscayl or Let's Enhance subscriptions.

Use cases

• E-commerce: sharpen supplier product photos for your store and marketplaces.
• Print and merch: enlarge artwork, logos and photos for posters, t-shirts and mugs.
• AI art: upscale Midjourney, Stable Diffusion or DALL·E images to print resolution.
• Real estate and travel: improve low-resolution listing photos.
• Old photos and screenshots: recover detail from small or compressed images.

  "outputFormat": "png"
}

Output

Each upscaled image is saved in the run's storage, with one row per image in the dataset:

{
  "inputUrl": "https://example.com/photo-small.jpg",
  "outputUrl": "https://api.apify.com/v2/key-value-stores/abc123/records/0001-photo-small-x4.png",
  "scale": 4,
  "format": "png",
  "inputWidth": 500,
  "inputHeight": 375,
  "outputWidth": 2000,
  "outputHeight": 1500,
  "inputResizedToFit": false,
  "outputBytes": 3815442,
  "seconds": 4.2
}

The Upscaled images view shows a before/after preview of every image. Images that can't be downloaded or opened are skipped (and not charged) and listed in the FAILED_IMAGES record.

Good to know

• 4x of a 700x700 image gives 2800x2800 (8 megapixels); with the 1 MP limit, 1000x1000 gives 4000x4000 (16 megapixels).
• Each image takes a few seconds (about 8 s for 500x500 at 4x).
• Works best on photos, product shots, illustrations and AI art. Tiny text may not become readable if it was never in the image.
• Transparency (PNG alpha) is kept.
