How do I enhance a picture for free?

Drop your picture on this page and the AI pass — Real-ESRGAN detail reconstruction — starts on its own; Auto levels and the sliders correct tone and colour on top. It is free with no account, no watermark and no daily quota. The before/after split shows exactly what changed before you download.

Is this real AI picture enhancement?

Yes — the AI engine is Real-ESRGAN (the realesr-general-x4v3 model, a 1.2-million-parameter super-resolution network, BSD-licensed), and it runs on your own device through WebGPU or WebAssembly rather than on a server. The one-time download is the 4.9 MB model plus about 3 MB of runtime (5.5 MB on a device with WebGPU), cached after the first use.

Can it make a blurry picture look clearer?

Yes, within honest limits. AI enhance was trained on photos with real-world blur, noise and compression, so it genuinely reconstructs edges and texture in soft or low-quality shots — at 1× it cleans up without enlarging. Being a generative model it redraws detail rather than recovering the original pixels, so heavy motion blur stays unreadable and small faces or lettering can come out slightly stylised; for a photo that is merely a bit soft, the sharpness slider is often enough.

Can I increase a picture's resolution?

Yes, up to 4× the original width and height. AI enhance upscales natively at ×4 and derives the 2× and 1× outputs from that pass, so a 900×600 photo becomes 3600×2400 px with reconstructed detail. Output is capped at 40 megapixels.

Can I paste a picture instead of picking one?

Yes — press Ctrl+V (⌘V on a Mac) anywhere on the page and whatever picture is on your clipboard is added to the enhancer. That covers a screenshot you just took, a picture copied out of a chat window or a web page, and files copied in Finder or File Explorer; copy several at once and all of them arrive together, numbered pasted-1, pasted-2 and so on since the clipboard supplies no filenames. Anything that is not a JPG, PNG or WebP is ignored, and the AI pass starts on the pasted picture by itself. Copy sends the result the other way, back onto your clipboard as a PNG.

What formats and sizes can I enhance?

JPG/JPEG, PNG and WebP, up to 20 pictures per batch, and every file downloads in its own input format with PNG/WebP transparency intact. The AI pass reads at most 4 megapixels on GPU-accelerated devices (0.7 MP on CPU-only ones) and downscales bigger photos first; the final output can be up to 40 megapixels.

How long does AI enhancement take?

On a device with WebGPU (most desktop Chrome, Edge and recent Firefox) the model runs on your graphics card: a few seconds for a small photo, about half a minute for a 1920×1080 one. Without GPU acceleration it falls back to single-threaded WebAssembly and a full-size photo can take a minute or two — a tile-by-tile progress bar and a Cancel button keep that bearable.

Where do my pictures get processed?

Entirely on your device — no photo, filename or pixel ever leaves your browser, because there is no upload endpoint at all. The only network traffic the enhancer causes is in the other direction: fetching the AI engine — the model plus its runtime — to you once. After that the whole tool keeps working with the network switched off.

Does the enhancer work on a phone?

Yes — every current mobile browser runs it, and the controls are sized for touch. On iPhone and iPad the AI engine deliberately uses the conservative CPU path (WebKit's WebGPU stack still mishandles the runtime), so AI passes are slower there and read at most 0.7 megapixels.

Free online picture enhancer

Enhance a picture in three clicks

Enhance Picture is a free tool that pairs instant one-click corrections for dull, dark or soft photos with a genuine Real-ESRGAN AI model that rebuilds detail and upscales to 2× or 4× — running on your own device, never on a server. No account is needed, JPG, PNG and WebP are supported, up to 20 pictures go in one batch, and the AI download — the 4.9 MB model plus its runtime — happens once and is cached.

Drop a photo below — the AI pass starts on its own — and drag the split preview to compare before and after.

How to use the picture enhancer

Free, no account, and done in about the time it takes to open a photo editor.

Add the picture you want to fix
Drag a JPG, PNG or WebP onto the drop zone, tap Choose pictures to pick from your phone or computer, or press Ctrl+V (⌘V on a Mac) to paste one straight from the clipboard — a screenshot you just took counts. Add up to 20 in one batch; the newest picture goes to the top of the list.
Pick a scale
The AI pass starts on its own: the Real-ESRGAN super-resolution model runs on your device and rebuilds detail at 1×, 2× or 4× — 2× unless you pick another scale. Auto levels and the brightness, contrast, colour and sharpness sliders then work on top of the result, with a split preview comparing before and after.
Save the enhanced file
Press Download enhanced for the picture on screen, or Download all to write out the whole batch with the same settings applied. Copy puts the enhanced picture on your clipboard as a PNG instead, ready to paste into a message or a document without a trip through your downloads folder.

About Enhance Picture

Photos disappoint in two different ways, so Enhance Picture carries two different kinds of fix. Some shots are merely flat — the camera exposed for the whole frame, the sky ate the contrast — and those need nothing more than honest corrections. Others are genuinely short on pixels: a thumbnail saved from a chat, an old export, a crop that got too ambitious. Those need detail put back, which is a job for a neural network.

Auto levels and four sliders handle the first case. Auto levels measures where your picture's darkest and brightest 0.4% of pixels sit in each colour channel and stretches the range back to full black and full white; the sliders layer on tone curves, a luma-preserving saturation pass so skin stays believable, and an unsharp mask for soft edges.

AI enhance handles the second case with Real-ESRGAN — the realesr-general-x4v3 super-resolution network — executed entirely on your device through WebGPU, or WebAssembly where no GPU is available. The picture is processed in overlapping tiles at 4× and delivered at 1×, 2× or 4×, and because it is a generative model it redraws plausible texture rather than merely magnifying pixels. The fine-tune sliders apply on top, and nothing in either stage ever transmits your photograph anywhere. If your photo is the right size but looks compressed or noisy, the enhance picture quality page starts the same AI pass at 1× — better quality without enlarging the photo. If it is the opposite problem and the photo is simply too small, the enhance picture resolution page opens at 4× and shows what the new pixel dimensions will be.

Guides

Nothing is uploaded

Decoding, correction and re-encoding all happen on your own device through the Canvas API. There is no server that receives your photograph, so there is nothing for us to store, inspect or hand over — and once the AI engine has downloaded the enhancer keeps running with the network switched off.
