Can I compress an image to an exact file size like 20KB?

Yes — pick a preset (20, 50, 100, 200 or 500 KB) or a custom target, and the tool iterates the compression until the file lands at that size.

How many images can I compress at once?

Up to 20 images in a single batch.

Can I resize to a specific size, like a YouTube thumbnail?

Yes — presets like YouTube Thumbnail (1280×720) and HD 1080p (1920×1080) are built in, alongside custom dimensions.

Are my images uploaded to a server?

No — compression and resizing run entirely in your browser using the Canvas API; images never leave your device.
