Frequently asked questions
How much smaller will my images get?
Photos usually shrink by 50–90% without a visible difference. A smaller maximum width saves even more.
Which quality should I choose?
75–85% is ideal for most photos. Below that, artifacts may become visible on close inspection.
Are my images uploaded?
No. HowDoIImage runs entirely in your browser. Your images are not sent to any server and stay on your device – ideal for private photos too.
Is “Compress image” free?
Yes, completely free – no sign-up, no watermark and no limit on the number of images.
Does it work on my phone?
Yes. The tool works in any modern browser on iPhone, iPad, Android, Windows, Mac and Linux – no app needed.
