Everything you need, nothing you don't
A precision instrument for image weight — tuned for speed, built for privacy.
Instant compression
Images are tuned the moment they land in the studio. No queue, no server round-trip, no progress bar theatre — just results.
Private by design
Your photos never leave your device. There is no upload, no account and no tracking — the studio runs entirely in your browser.
Quality you control
Dial in the exact balance of size and sharpness with the quality tuner, and compare original vs. optimized sizes per file.
Metadata stripped
Re-encoding removes hidden EXIF data such as GPS location and camera serial numbers, so you never share more than the picture.
Batch everything
Drop a whole folder's worth of images at once. Optimize them together and grab a single ZIP with every tuned file inside.
Smart resizing
Cap the maximum width for web delivery. imgTuNe downscales with high-quality resampling so photos stay crisp at any size.
Your images stay yours. That's also why it's fast.
- No uploads, ever. Compression runs on your own CPU using your browser's native encoders — files never touch a server.
- No network wait. Skipping the upload/download round-trip means even large batches finish in seconds, not minutes.
- No accounts or limits. Nothing to sign up for, no daily quota, no watermarks — optimize as much as you like.
- Sensitive metadata removed. GPS positions, device identifiers and other EXIF data are dropped during re-encoding.

Tune the dials
Set quality, pick an output format (or leave it on AUTO), and optionally cap the width for web-ready sizes.
Download the savings
Grab files one by one or everything as a ZIP. Each row shows exactly how many kilobytes you just saved.
