EnhanceLab: enhance photos & videos with AI, free in your browser
Welcome to the Enhance Lab. Upscale blurry photos with a real neural network, clean up videos up to 5 minutes, generate images from a prompt, and copy today's viral shorts prompts, right here on this page. No app to install, no account, no watermark.
AI Photo Enhancer
A real neural network (ESPCN super-resolution) runs on your device with WebAssembly. It rebuilds detail in the brightness channel while colour is upscaled in high quality.
4K max exports your photo at 3840px on the long edge, the maximum quality this tool offers.
Ultra adds a second detail-recovery pass with stronger local contrast. A little slower, visibly sharper.
Each pack is a curated combination of the upscale, quality and slider settings above and below. One tap applies it; fine-tune afterwards as usual.
Light, natural retouching with classical image processing — not AI face reconstruction. Your face stays exactly your face, and face preservation above stays on.
Skin smoothing works on any skin tones it finds. Teeth whitening and eye-bag softening also need a face the browser can detect in the photo; when none is detected, those two simply stay off and the note under your result says so.
One tap cuts the subject out of the photo loaded above and gives you a transparent PNG, ready to drop onto any background or thumbnail. Segmentation runs in your browser: it works best on a fairly plain background, and fine hair or busy backgrounds can leave rough edges — that is the honest limit of in-browser removal.
Drag the slider on the result to compare before and after.
Background Remover
Video background — blur or replace
Load a short clip and the subject is kept while the background is blurred or swapped for a solid colour, live in the preview and in the export. Plain, even backgrounds work best; a moving camera and busy scenes can confuse the cutout.
Video Enhancer — HD Upscale
Real HD upscaling first: a 480p or 720p video is rebuilt at full 1080p HD with high-quality resampling, detail recovery and noise removal, not just a colour filter. The default preset adds the rich HDR look, deep contrast and tack-sharp detail on the brightness channel only, so your colours stay exactly as shot. Preview and export run at the full output resolution. Drag the split divider on the preview to compare before and after. Honest note: upscaling rebuilds and sharpens the detail that is in your video; no free browser tool can invent brand-new detail the way a paid cloud AI can.
HD upscale rebuilds 480p and 720p videos at 1920-wide Full HD. Videos already in HD keep their full original resolution.
HD Enhance (the default) gives the rich HDR look, deep blacks, bright highlights and tack-sharp detail, without ever changing your colours: all of it happens on the brightness channel only, so the colours you shot stay exactly your colours. Vivid is the full HDR rich look: the deepest contrast, maximum sharpness and a gentle, natural colour lift. Cinematic is a softer film style.
Curated looks that set every control below in one tap: Viral HDR, Cinematic, Y2K DigiCam, Clean Pro and Golden Hour. Fine-tune afterwards as usual.
Light classical smoothing on skin tones only, applied live in the preview and in the export. Faces stay the same person — no reshaping, no AI face reconstruction. Teeth whitening and eye-bag softening live in the Photo Enhancer.
Press play, adjust the sliders, then export when it looks right.
AI Image Generator
Type what you imagine, pick a style, and create a photo or artwork in seconds. Images are generated by a free AI service (Pollinations).
Write a detailed prompt for the best result: subject, place, light, mood and style.
Today's Viral Shorts Prompts: 10 ready-to-copy templates
Trending formats for YouTube Shorts, Facebook Reels and TikTok. Copy a prompt, paste it into the free tool listed on the card, follow the 3 steps, and post. Update the words in [brackets] with your own idea.
Voice + Clips Auto-Assembler
Recorded a voiceover and shot a pile of short clips? Add both, paste the script, tag your clips, and this tool assembles the finished video for you: clips placed on the matching script sections, cut or looped to fit, captions burned in, transitions added and your voice mixed over the top. Honest note: matching works by the keyword tags you give each clip (for example "lion", "fight") — the tool does not watch or understand your clips, so good tags mean good matches. Everything runs on your device; nothing is uploaded.
The same looks as the Video Enhancer, applied to every frame of the assembled video — you see them live in the preview, and they are baked into the export.
Clips are centre-cropped to fill the frame, cut when they are longer than their section and looped when they are shorter.
Captions: script-timed — each section is timed by its word count. Auto-transcribe listens to your voiceover on your device (a small speech model downloads once, about 40 MB, then works offline) and replaces them with captions timed to the real words.
Add a voiceover, paste the script and split it into sections to build the timeline.
Script to Video
Before making the video, there's just one decision — where will the voice come from? Pick a path; the script editor opens right after it, and your choice is remembered. If you want to change it later, the “Change voice path” button at the top of the editor brings you back here.
Record yourself reading the full script on your phone and upload it here — your voice will be inside the downloaded video. No key, no sign-up, no cost.
Studio-quality AI voices from your own free ElevenLabs account — every free account gets 10,000 free credits every month. Getting the key takes about 2 minutes; the guide below shows every step.
Honest note: the demo below is an animated guide — it is not a real screen recording. It is an illustrated mock made only to explain the steps; ElevenLabs' real screens look almost exactly like this.
This guide plays on its own in a loop of about 30 seconds — 6 steps, one after another.
The editor opens right away, and step 3 has the same 3-step wizard — create the account, copy the key, paste it here.
Video to Prompt
Found a video you love and want to remake it with an AI video tool? Upload it here: the tool measures it frame by frame — duration, scenes and cuts, dominant colours, brightness, contrast, motion, pacing — pulls out its keyframes, and writes a detailed, copy-ready prompt describing the video. Paste the prompt into Sora, Runway, Pika, Kling or any AI video generator to create a similar video there. This tool analyzes and describes — it does not generate video itself.
Upload a video and tap Analyze — one keyframe per scene, plus one every couple of seconds.
Shorts Extractor
Upload a long video and this tool finds the moments most likely to work as Shorts. It measures scene changes, motion intensity and audio energy second by second, ranks the strongest windows by viral potential, then cuts them as vertical 9:16 videos with smart centre-of-action cropping and burned-in captions. Add your own narration to any short before exporting it. Everything runs on your device; the video is never uploaded.
The top moments are ticked for you. You can untick or tick any moment in the list before exporting.
Captions: typed by you, timed by word count. Auto-transcribe listens to the video's audio on your device (a small speech model downloads once, about 40 MB, then works offline) and fills every moment's caption with the real words, timed to when they are spoken.
Upload a long video and tap Analyze — the strongest moments are listed with their viral score, a vertical preview frame, caption and narration options, and an export button each.
Batch Enhance
Add a pile of photos and videos, pick one template pack, and EnhanceLab works through the queue one by one. Watch each item's progress on the right, then download the results one by one or all together. Everything runs on your device; nothing is uploaded.
Add photos and videos on the left — each one shows its own progress: queued, processing, done or failed.
1Pick your photo or video
Tap a tool above and choose a file from your phone or computer. Nothing is uploaded: the file stays on your device from start to finish.
2Enhance it right here
Photos are upscaled by a real AI neural network with detail recovery; videos are upscaled to Full HD with detail recovery and noise removal, with a live split before/after preview. Most photos are ready in seconds.
3Download & post it
Save the result with no watermark and post it anywhere: TikTok, Facebook, Instagram, YouTube. Come back any time, it stays free.
Why it is private
Most "free" enhancer sites upload your photos to their servers. These tools run entirely on your own device using WebAssembly and canvas processing, so your files are never sent anywhere. Close the tab and everything is gone.
How the photo AI works
The photo tool uses ESPCN, a published neural super-resolution model, running locally through ONNX Runtime. It predicts real detail in the brightness channel at 3×, then detail recovery, local contrast (CLAHE) and sharpening finish the job. Ultra quality runs a second detail pass. 2× and 4× are finished from that AI result.
Honest about video
The video tool does a real resolution increase: 480p and 720p videos are rebuilt at 1920-wide Full HD using high-quality resampling, then detail recovery, deblocking and temporal noise removal clean the picture up frame by frame. Honest limit: it recovers and sharpens the detail in your footage, it does not invent new detail like a paid cloud AI, and it does not upscale to 4K.

Quick questions
What is EnhanceLab?
EnhanceLab (also searched as "Enhance Lab") is a free online photo and video enhancer from Digital Tools Store. It upscales and sharpens photos with a neural network, enhances videos up to 5 minutes, and includes an AI image generator and viral shorts prompts. Everything runs in your browser, so there is nothing to install and your files never leave your device.
Are my photos and videos uploaded anywhere?
No. All processing happens in your browser on your own device. There is no server, no account and no tracking in these tools. You can even load this page, go offline, and keep using them.
Is it really free?
Yes, everything on this page is free right now. Free plan limits are generous and simple: videos up to 5 minutes and photos up to 12 MP. Because the enhancers run on your device instead of expensive cloud servers, there are no credits and no watermarks.
How does the AI Image Generator work?
Type a prompt, choose a style and ratio, and tap Generate. The image is created by the free Pollinations AI service, so this one tool needs an internet connection. You can download the result and use it in your posts, thumbnails and shorts.
Can I generate a video from a prompt here?
Not from a bare prompt, and we will not fake it: there is no truly free AI video generator API. But two tabs do build real videos for you: Script to Video turns a pasted script into a full video with stock footage, a device voiceover and captions, and the Video Assembler joins your own voiceover and clips into a finished video automatically. For AI-generated footage, use the Viral Video Prompts tab: 10 ready-to-copy prompts tuned for the free tiers of popular video tools, each with a 3-step guide.
What photo size works best?
Photos up to about 2 megapixels are processed at full size by the AI. Larger photos are first reduced to a 2 MP working copy (you will see a note when that happens), which still produces a much sharper result than the original. Choose the 4K max upscale option to export at 3840px on the long edge.
Will enhancing change my face?
No. Face preservation is on by default: there is no beautifying, no skin smoothing, no reshaping and no face swapping anywhere in these tools. The enhancer only adds sharpness and clarity, and it deliberately softens the detail boost on skin tones, so the person in the photo stays exactly the same person, just clearer.
Does the video tool really make my video HD?
Yes, the resolution really increases. With HD upscale on (the default), a 720p video (1280 × 720) is exported at 1920 × 1080 and a 480p video at 1920 wide, using high-quality resampling plus detail recovery, deblocking and noise removal so the bigger picture also looks cleaner. The preview shows the exact source and output sizes before you export. Videos that are already HD are processed and exported at their full original resolution.
Why does video export take as long as the video itself?
The enhanced picture is recorded in real time while the video plays, entirely on your device, at the full output resolution. That is the trade-off for keeping your video private instead of uploading it to a cloud service.
Which browsers work best?
Chrome and Edge give the fastest results. Firefox works well too. On iPhones, Safari supports the photo tool fully; video export depends on your iOS version.
