Question 1

Which image tool should I use first?

Accepted Answer

If your goal is a smaller file, start with Compress — it usually removes 60–90% of the size with no visible difference. If the image is also far bigger than it needs to be on screen, resize it first and then compress; scaling a 4000px photo down to 1200px often saves more than any codec setting.

Question 2

Are these tools really free with no limits?

Accepted Answer

Yes. There is no account, no watermark, no daily quota and no file-count cap. Because every operation runs on your own device, there is no server bill to pass on to you.

Question 3

Do the image tools work on a phone?

Accepted Answer

Yes, in any modern mobile browser including Safari on iPhone and Chrome on Android. Very large photos take longer on a phone because the work uses your device's own processor.
