AI Image Upscaler (2x, 3x, 4x, Real-ESRGAN)

Make small or blurry images 2, 3 or 4 times larger with sharper detail. Product photos, old photos, thumbnails, artwork and AI images all work. It uses Real-ESRGAN, an open-source AI upscaler that removes blur and JPEG noise while it enlarges. Paste image links or upload an image and get download links to the upscaled files.

Price: US$0.015 per image (input up to 1 megapixel), plus a US$0.003 run fee. 100 images cost US$1.503.

What people use it for

• E-commerce: enlarge supplier photos to meet marketplace minimum sizes (Amazon, Etsy, Shopify zoom).
• Print: bring web-size images up to print resolution.
• AI images: upscale Midjourney, DALL-E or Stable Diffusion output to 4x.
• Old photos and thumbnails: recover detail from small or compressed images.
• Automation: upscale images in bulk from a pipeline or AI agent, with JSON results.

The upscaled files are saved in the run's key-value store. outputUrl downloads each one. Transparent PNG and WebP images keep their transparency.

Input

Field	What it does	Default
imageUrls	Direct links to images, up to 500. JPEG, PNG, WebP, GIF, BMP, TIFF. 30 MB and 6.25 megapixels per image.	1 sample image
uploadedFile	Or upload one image from your computer.	none
scale	2, 3 or 4 times larger on each side.	4
outputFormat	png (lossless), jpg (smaller files) or webp (smallest).	png

Results are capped at 25 megapixels (for example 5000 x 5000). If the scale you pick would go over that, the image gets the largest scale that fits, and the row says so.

Pricing

Event	Price
Run fee, once per run (per 4 GB of memory; the default is 4 GB)	US$0.003
Image upscaled (input up to 1 megapixel, for example 1000 x 1000)	US$0.015
Each started megapixel of input above the first	US$0.015

Examples: one 500 x 500 image costs US$0.018. 100 images of up to 1 MP cost US$1.503. One 2000 x 1500 image (3 MP) costs US$0.048. The price depends on the input size only, so 2x, 3x and 4x cost the same. Images that fail to download or open are listed with the reason and not charged.

Limits

• Real-ESRGAN sharpens and cleans. It cannot invent detail that was never in the photo, so very tiny faces and text stay soft.
• It runs on CPU. Expect about 30 to 45 seconds per megapixel of input at the default memory. Raise the run's memory for more CPU cores and faster runs.
• Free Apify plan: up to 3 images per run.

FAQ

Which model is it? Real-ESRGAN general x4v3 (BSD-3-Clause licence), the general-purpose model for photos and artwork.

Can an AI agent call it? Yes. Pass image links, get JSON with download links back, and pay per image.

Are my images kept? Results stay in your own Apify storage, under your account's data retention settings. Nothing is shared with third parties.
