Upscaled result
Sharper high resolution
Upscale image size while improving perceived clarity, edge definition, and texture so small assets can become clean hero graphics, catalog images, and presentation visuals.
SeedVR restoration
The AI image upscaler uses fal.ai SeedVR to rebuild detail instead of stretching pixels, helping portraits, product edges, packaging, and soft materials look more polished.
One-credit workflow
Each upscale image request costs one credit, making it easy to repeat the upscale image workflow for thumbnails, marketplace photos, team assets, and launch materials.
Simple workflow
Upscale image quality in three focused steps
NanoPhoto.AI keeps the upscale image workflow short enough for daily production work while still giving teams a serious high-resolution result. Instead of opening a heavy editor, resizing manually, sharpening with guesswork, and exporting multiple versions, you upload a file or paste a public image URL, choose 2x or 4x, and download the enhanced image. The page is designed for people who need to upscale image assets quickly without handing the FAL_API_KEY to the browser or running a separate desktop tool.
Upload or paste
Start with a product photo, creator portrait, logo mockup, listing image, or social graphic. You can upload a local file or paste a public HTTPS URL, then NanoPhoto.AI prepares the upscale image request on the server so the API key stays private.
Choose 2x or 4x
Select a balanced 2x upscale image pass for everyday improvement or a larger 4x upscale image pass when you need more pixels for cropping, banners, hero sections, print drafts, or marketplace zoom views.
Download the result
When the result is ready, download a JPG, PNG, or WebP image. Use the upscaled image in a product gallery, pitch deck, ad creative, thumbnail, landing page, or another NanoPhoto.AI workflow without rebuilding the asset by hand.
Built for creators, shops, and small teams
A reliable upscale image tool saves time whenever one low-resolution asset needs to work across more placements. Use it before building banners, catalog pages, course slides, comparison graphics, creator thumbnails, or sales decks. Teams that upscale image assets early can reuse the same source photo across more channels without waiting for a reshoot.
Product listings
Marketplace teams upscale image files from suppliers, phones, and old catalogs so SKU photos look more consistent. A sharper upscaled image can support zoom views, ads, and seasonal layouts without changing the original product.
Creator visuals
YouTubers, educators, newsletter writers, and founders upscale image thumbnails, portraits, screenshots, and props before placing them into covers, tutorials, pitch slides, or launch graphics.
Design cleanup
Design and marketing teams upscale image assets before cropping, retouching, removing backgrounds, or generating new scenes. It is a fast prep step for cleaner compositions and more flexible final exports.
Upscale image FAQ
Answers for teams using NanoPhoto.AI as a daily upscale image tool and a dependable way to upscale image quality before publishing, selling, or designing.
How does NanoPhoto.AI upscale image files?
NanoPhoto.AI sends your image to the fal.ai SeedVR upscale image model through a secure server route. The model increases resolution, restores fine texture, and returns a new high-resolution image. Your FAL_API_KEY stays on the server, so the browser never exposes the key.
How many credits does it cost to upscale image quality?
One image costs one credit. NanoPhoto.AI pre-deducts that credit before processing to prevent concurrent abuse. If the upscale image request fails, the credit is refunded automatically so failed generation does not cost the user.
Should I choose 2x or 4x when I upscale image assets?
Choose 2x for most product photos, portraits, thumbnails, and web images because it balances sharpness and speed. Choose 4x when you need extra pixels for crops, larger banners, print drafts, or close-up detail. Very tiny or heavily compressed images may still have limits.
Which image types work best?
PNG, JPG, and WebP files work well when the subject is visible and not extremely blurred. Product photos, faces, packaging, graphics, screenshots, and marketplace assets usually benefit from an upscale image pass when the original has enough detail to recover.
Can I upscale image files from a hosted URL?
Yes. Paste a public HTTPS image URL when your file already lives on a CDN, website, or storage bucket. Private links, expired URLs, or hosts that block automated access may fail, so uploading the image is usually safer for one-off work.
Is this different from normal resizing or sharpening?
Yes. Normal resizing mostly stretches pixels, while an AI upscale image model predicts missing detail and improves edges, texture, and perceived clarity. Manual retouching is still useful for art direction, but NanoPhoto.AI is designed for fast high-resolution assets that are ready to reuse.
