Question 1

How does the bulk image compressor work?

Accepted Answer

You upload multiple images at once, drag the quality slider to your desired level, and the tool shows a size-savings preview for each file before you download them.

Question 2

Are my photos uploaded anywhere when I compress them?

Accepted Answer

No, all compression happens locally in your browser, so your images never leave your device.

Question 3

Is there a limit to how many images I can compress at once?

Accepted Answer

You can compress many images in one batch, but very large batches or very high-resolution files can slow down or use a lot of memory since everything is processed by your browser rather than a server.

Question 4

Do I need an account to compress images in bulk?

Accepted Answer

No account or payment is needed, the tool is free to use directly in your browser.

Question 5

Does compressing an image change its dimensions?

Accepted Answer

No, the compressor only reduces file size by adjusting quality, it doesn't resize the image's width or height. Use the Resize & Crop tool if you also need to change dimensions.
