FAQ – Image Compressor

Is my photo uploaded?

No, all compression happens directly in your browser. Your images never leave your device.

What file types are supported?

You can upload JPG, PNG, WebP, and more. All outputs are JPEG for maximum compression.

How can I compress many photos at once?

Just select multiple images (hold Ctrl or Shift, or long-tap on mobile), and all will be processed in a batch.

How much can I reduce the size?

Typical reduction is 50–90% depending on original quality and your settings.

Is there a limit on file size or number of images?

There are no fixed limits, but your browser's memory may limit very large batches (try 20–30 at once for best performance).

Do you add watermarks or charge fees?

No watermark, no registration, and it's completely free for unlimited use.
