Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To optimize images, add up to 10 files to the batch image optimizer, let it compress and resize them with sensible settings, and download the lighter results one by one or all at once. Everything runs in your browser, so the images never leave your device and there is no upload queue to wait on.
This is most useful before publishing, when files are too heavy, the page builder feels slow, or an upload form rejects oversized images. Optimizing early keeps your images readable while cutting page weight, which helps load times and Core Web Vitals.
Yes. The batch image optimizer is free with no sign-up, no watermark, and no cost per image. You can run as many batches as you need.
It is private because all compression and resizing happen client-side in your browser. Your images stay on your device and are never sent to a server, which makes it safe for client work, internal assets, and anything you would rather not upload.
The optimizer handles up to 10 images per batch, a practical limit that keeps the tool responsive on normal laptops and phones since the work runs locally rather than on a server. For small publishing sets, this is usually all you need.
For very large batches or advanced formats, server-side processing can be more efficient, but for everyday website and upload work, browser-based optimization is faster, cheaper, and more private. Just add another batch when you have more files.
Short answers for the questions people usually have before trying a utility like this.
Yes. The batch image optimizer is completely free with no sign-up, no watermark, and no limit on how many batches you run.
No. The optimizer runs entirely in your browser, so your images stay on your device and are never uploaded to a server.
You can optimize up to 10 images in a single batch, which keeps the tool fast and responsive on regular laptops and phones.
The optimizer aims for a strong balance, shrinking file size while keeping images visually clean and readable for web use.
Yes. It works in any modern mobile or desktop browser because all optimization happens locally on your device.
