Two credits, about three seconds. 2× — width and height, every run 2–3s — typical time 2 — credits per image 10 MB — max upload ## What 2× actually looks like A whole-image slider cannot show an upscale: both halves get scaled to the same width on screen, so they look identical. This is a 100% crop of the same patch — the left comes from a 448 × 327 source, the right from the 896 × 654 output. After Before Drag to Compare Before & After Same patch of crust: 179 px of source against 359 px of output, shown at one size ## Will Image Upscaler work on your photo? Match what is wrong with your image to what this tool can realistically do. Where it cannot help, the row says which tool can. ### A small photo you need bigger Good match The core case. Our sample went from 448 × 327 to 896 × 654 with the crust texture and flour on the loaf holding up instead of smearing. ### Line art, anime, screenshots Good match Edges and lettering keep their definition rather than turning into gradients, which is what plain resizing does. ### Already large and sharp Partial improvement You will get a file at twice the dimensions, but there is little latent detail to recover. Run it only when you actually need the pixel count. ### You need more than 2× Partial improvement Upload the output and run it again. Two passes give four times the original for four credits. ### A blurry face Use another tool Enlarging a blurry face enlarges the blur. Sharpen it first with [Unblur Face](https://www.aiimagetools.net/tools/ai-face-restoration) ## How to upscale an image to 4K (and when you don't need to) Every run here is a true 2× in width and height, so getting to a target size is simple arithmetic. Work out how many passes you need before you upscale an image, and don't enlarge what is already big enough. ### Upscale image to 4K 4K is 3840 × 2160. An image at least 1920 pixels wide reaches 4K width in one pass; one at least 960 pixels wide needs two. Smaller than that and even two passes fall short, so look for a larger original first. ### Upscale image for print Print needs about 300 pixels per inch for a sharp result. A 1,000-pixel image prints well at roughly 3 inches; one pass doubles that to about 7 inches, two passes to about 13. Posters viewed from a distance get away with less. ### Upscaling vs. resizing in an editor Resizing in a photo editor stretches the existing pixels, so edges blur and text turns into gradients. The upscaler predicts the missing detail instead, which is why lines, lettering and hair stay crisp at the larger size. ### When not to upscale Most recent phone photos are already 4,000 pixels or more across; upscaling them adds file size, not detail. The tool earns its keep on small web images, old digital photos, thumbnails, screenshots and AI images generated at 1K. ### Fix first, upscale last Blur, noise and damage are enlarged along with everything else. Restore or unblur first, then upscale the image as the final step. ## Why Image Upscaler on AI Image Tools ### A real 2×, stated plainly The engine doubles width and height. We do not advertise 4× or 8× buttons that quietly deliver less. ### Edges stay crisp Lines, lettering and hair keep their definition instead of turning into blur, which is what plain resizing does. ### Fast enough for a whole folder Two to three seconds per image at two credits each, so a batch of product shots costs less than a coffee. ### Run it twice for 4× Need more? Upload the result again. Two passes give you four times the original size for four credits. ## Image Upscaler specifications InputOne JPG, PNG, WebP or HEIC up to 10 MB Factor2× (fixed) — measured: 448 × 327 in, 896 × 654 out EngineRecraft crisp upscale OutputWebP, saved to My Creations SettingsNone; upload and run Cost2 credits per image Time2 to 3 seconds Free plan10 credits on sign-in — 10 images on the default model ## How to use Image Upscaler - Step 1 ### Upload the image Photos, renders, illustrations and screenshots all work. Keep the source under 10 MB. - Step 2 ### Upscale No factor to choose; every run is 2×. - Step 3 ### Download, or go again Download the WebP, or upload the result for another 2× pass. ## Get a better result A few choices before you upload change the output more than any setting on this page. ### Start from the original file Enlarging a screenshot enlarges its compression blocks along with everything else. Find the earliest copy first. ### Repair before you enlarge Damage, blur and noise all get bigger too. Put the fix first and the upscale last.

Running the result again is the honest way to get there, and it costs four credits. ## Pricing Every tool draws from one balance. 40% OFF No hidden fees • Cancel anytime • Unused credits roll over 16% OFF - Save $18.8 $8.3/month $9.9/month $100/year billed yearly 480images / year $0.21 per image on Nano Banana - [Included] 2,400 Credits renew yearly - [Included] Or 120 images in 4KGPT Image 2.5 · 4K - [Included] All 26 tools, one balance - [Included] All 18 models, including the 4K tiers - [Included] Download without watermark 20% OFF - Save $70.8 Popular $24.0/month $29.9/month $288/year billed yearly 1,920images / year $0.15 per image on Nano Banana - [Included] 9,600 Credits renew yearly - [Included] Or 480 images in 4KGPT Image 2.5 · 4K - [Included] All 26 tools, one balance - [Included] All 18 models, including the 4K tiers - [Included] Download without watermark 40% OFF - Save $238.8 $30.0/month $49.9/month $360/year billed yearly 4,320images / year $0.083 per image on Nano Banana - [Included] 21,600 Credits renew yearly - [Included] Or 1,080 images in 4KGPT Image 2.5 · 4K - [Included] All 26 tools, one balance - [Included] All 18 models, including the 4K tiers - [Included] Download without watermark Swipe to compare plans → ## Image Upscaler: frequently asked questions ### ### Can I upscale more than 2×? Yes, by running the output again. Each pass is 2× and costs two credits. ### ### Can I upscale images for free? Each pass costs 2 credits, so the 10 credits you get at sign-in cover 5 upscales. Upscaler results are not watermarked, on the free plan too. ### ### Photos or illustrations? Both. Line art and anime keep clean edges; photos keep grain rather than turning waxy. ### ### What is the largest input? 10 MB per file. Very large sources are already big; the tool is most useful on images under about 2000 pixels on the long side. ### ### Why WebP? It is what the engine returns and it keeps 4K-sized outputs small. Convert to PNG or JPG if you need those specifically. ### ### What happens if a generation fails? You are only charged when an image comes back. If the model fails or times out, nothing is deducted and you can simply run it again. ### ### What happens to my photos? Your upload is sent to the model provider only to produce the result. The result is stored in your My Creations gallery on our own storage, and you can delete it there at any time. ## Twice the pixels, none of the blur Upload at the top of the page.
