  3. Download each compressed image. Done.

Why compress images?

Large images slow down websites, fill up storage, and are hard to email. Compressing them keeps the visible quality while cutting the file size by 50–90%. Because this tool works entirely offline in your browser, it's faster and more private than upload-based services.

Frequently asked questions

Are my images uploaded to a server?

No. Everything runs locally in your browser using the HTML Canvas API. Your images never leave your device.

What formats are supported?

JPG/JPEG, PNG, and WebP. Output is encoded as JPEG or WebP for the best compression.

Is there a file size or count limit?

There's no hard limit, but very large images depend on your device's memory. Most photos compress in well under a second.
