Upscale Images to Ultra-High Resolution
AI image upscaling takes a low-resolution image and intelligently reconstructs it at 2x or 4x the original size, adding realistic detail that was never in the source. Powered by Topaz AI, Apatero's upscaler preserves sharpness, recovers textures, and eliminates compression artifacts in a single click.

Traditional upscaling (bicubic, Lanczos) simply stretches pixels, resulting in blurry, soft images. AI upscaling is fundamentally different. It uses neural networks trained on millions of image pairs to predict and reconstruct fine details like skin pores, hair strands, fabric weave, and architectural edges. Apatero integrates Topaz AI upscaling directly into the generation pipeline, so you can upscale any image immediately after creating it. The result is print-ready output at resolutions up to 8192x8192 pixels, perfect for posters, product mockups, and professional portfolios.
Step-by-Step Image Upscaling Workflow
Follow these steps to get the best results with image upscaling on Apatero
Select Your Image
Choose any AI-generated or uploaded image from your Apatero library. The upscaler works on images of any starting resolution, though results are best when the source is at least 512x512.
Choose Scale Factor
Select 2x for moderate enhancement or 4x for maximum resolution. 2x is ideal for web and social media. 4x is best for print, large displays, or when you need extreme detail.
Preview and Adjust
Preview the upscaled result before committing credits. Check critical areas like faces, text, and fine textures. Adjust sharpness and denoising settings if available.
Download High-Res Output
Download your upscaled image in PNG format for maximum quality. The output retains all enhanced detail without additional compression.
Tips for Better Image Upscaling Results
Use these tips to get the most out of image upscaling on Apatero
Upscale after all other edits (inpainting, face swap) to avoid re-processing at high resolution
Use 2x upscaling for social media and web content to keep file sizes manageable
4x upscaling works best on images with clear subjects and defined edges
For images with heavy noise or artifacts, consider regenerating at a higher base resolution first
Upscaling text-heavy images may produce artifacts, so add text overlays after upscaling instead
Batch upscale multiple images at once to save time on larger projects
Image Upscaling FAQ
Common questions about image upscaling on Apatero
What is the maximum resolution I can upscale to?
With 4x upscaling, a 2048x2048 source image becomes 8192x8192 pixels. This is more than enough for large-format printing, billboard graphics, and ultra-high-resolution displays.
Does upscaling add real detail or just make the image bigger?
AI upscaling adds genuine detail. The neural network predicts fine textures, sharpens edges, and reconstructs elements like hair, fabric, and skin that were not visible in the original. It is fundamentally different from simple resize tools.
How many credits does upscaling cost?
Image upscaling costs 5 credits per image on Apatero. This is one of the most affordable operations available, making it easy to upscale entire batches.
Can I upscale images I did not generate on Apatero?
Yes. You can upload any image to Apatero and run the upscaler on it. This works for photos, screenshots, artwork from other tools, or any image you want to enhance.
Is Topaz AI the same technology used by professional photographers?
Yes. Topaz AI is the industry standard for image enhancement, used by professional photographers, video editors, and studios worldwide. Apatero integrates the same technology directly into the platform.
