Frequently asked questions
Can I watermark many photos at once?
Yes. Select as many images as you like – all get the same watermark and are saved as a ZIP.
Does the size adapt to the image?
Yes. The size is relative to the image width, so the watermark looks the same on large and small images.
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 “Add watermark” 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.
