Welcome to the ultimate image intelligence suite. Edit, scrub, and compress massive image batches using your own device's native processor. We don't want your files, and our engine ensures they never leave your machine.
No signup required • Works instantly • 100% browser-based
The age of uploading sensitive data to a cloud server just to resize it is over. Hikaru Labs utilizes a "Zero-Server" architecture. We deploy our heavy-duty algorithms directly to your browser tab.
When you drop a file, it loads instantly because it is only traveling from your hard drive to your browser's memory. When you execute an operation, your CPU does the work. This guarantees true security and blazing-fast processing speed.
Drop image files or a massive ZIP archive. Files load into memory instantaneously. Zero network waiting time.
Stack your operations: Convert WEBP, target an exact 2MB size, and strip hidden data simultaneously.
Hit Commence. Your device's native CPU executes the algorithms. Files never cross the internet.
Download the individual files or export a secure .ZIP archive generated entirely on your own machine.
Specific tasks handled locally with zero latency.
Reduce JPEG file sizes significantly without losing visual quality. Because the compression happens in your browser, you never have to wait for large JPG files to upload or download.
Instantly convert heavy PNG graphics into lightweight JPG or WebP formats. Our local converter processes hundreds of files in seconds, completely bypassing cloud queues.
Protect your privacy before sharing photos. Our EXIF scrubber permanently deletes hidden GPS coordinates, camera metadata, and timestamp information directly on your device.
A comprehensive toolkit for bulk editing and precise data management.
Stop guessing with quality sliders. Type in the exact file size you need (e.g., 2.5MB), and our algorithm executes flawless compression to hit your target.
Identity protection. Instantly losslessly scrub private EXIF data, including GPS coordinates, camera models, and hidden tags from your images before posting online.
Digitizing analog data? Our built-in film scanner inverts negatives, auto-balances colors, and applies automated dust and grain cleanup logic.
Stop paying for print sheets. Upload a portrait and we automate tiling thirty 3.5x4.5cm photos onto a perfect A4 printable canvas instantly.
Convert file formats across PNG, JPEG, and WebP instantly. Processing locally completely removes the annoying backend wait times.
Resize entire bulk batches simultaneously. Resize by exact dimensions or use presets tailored for Instagram, YouTube thumbnails, and X (Twitter).
Processing 100+ files? Our bulk naming tool automatically adds unique prefixes and suffixes to all modified files to keep your desktop organized.
Correct orientation issues in bulk. Rotate entire image batches clockwise, counter-clockwise, or upside down instantly using your computer's power.
Protect your intellectual property. Type text and apply dynamic, professional watermarks to your entire batch of photos perfectly.

Everything you need to know about how Hikaru Labs works.
100%. Your photos never leave your computer. Everything happens right inside your web browser, so there are no cloud uploads or hidden servers processing your images.
Once you open the website, you can actually turn off your Wi-Fi! The tool runs entirely on your device's own processing power.
Nope! Because we don't upload anything to a server, you are only limited by your computer's RAM. Drop in a massive folder and watch it work instantly.
We currently support JPG, PNG, and WebP image formats. You can also drag and drop a whole .ZIP archive directly into the app, and it will process all the images inside it!
"I was brutalized by 'free' online tools holding my files hostage. Uploading 50 megabytes of private photography to a server just to compress it is backwards. It wastes bandwidth, it takes forever, and it hands your metadata and private data to a faceless corporation."
"So I built Hikaru Labs. I wanted an absolute weapon of a tool that ran strictly on the bare metal of the web browser. No bottlenecks. No hidden APIs stealing data. Pure mathematical efficiency running on your CPU."
"Winning Startup of the Year in 2026 proved one thing: the future of software isn't in the cloud. It's right there on your local machine. Take back control."
