Quick answers

FAQs

Can I compress multiple images at the same time?

Yes. You can add a batch of images, compress all of them together, review each file in the queue, and download selected files or the full batch.

Does the tool show before-and-after comparison?

Yes. The selected image gets a side-by-side comparison view so you can check the visual result, output size, and compression ratio before downloading.

Can I resize or change the output format?

Yes. You can change width and height, keep the aspect ratio locked, and export in WebP, JPG, PNG, or AVIF depending on browser support.

Are my images uploaded to a server?

No. Compression runs locally in your browser, which is useful when you want faster processing and do not want to send images to a server just to reduce file size.

How do I save the compressed images?

Download one image from its preview, or use Download All after processing a batch.

Does this tool store my data?

No. Your images are compressed in the browser and are not saved by the tool.
