FAQ
Is this tool free?
Yes — no sign-up, no installation, completely free to use right away.
What is this tool?
Batch compress images — shrink many photos at once with a quality slider or a target file size, and see how much each one saved. Free and private, all in your browser. You can use it for free with no sign-up or installation — just open the page and start right away.
Are my uploaded files sent to a server?
No. Everything runs only on your own computer, inside your browser, and your files are never sent to a server or anywhere else. So you can use it with complete peace of mind, without worrying about your file contents leaking.
How many images can I process at once?
There's no fixed limit — it runs in your browser, so it depends on your device's memory. Dozens to a few hundred images work smoothly; very large batches may take a little longer.
Is the original quality kept?
Compression trades some quality for smaller files — that's the point — but you control the quality level, and the preview shows the size saved.
