which is the best app/tool to watermark the photos?

Hi! You haven’t specified which OS, so i am sharing the best free to use watermark apps for apple and android phones.

iOS Apps

Photomarkr – Like many of the other apps, PhotoMarkr (free) lets you create a watermark using text — or you can import your own custom watermark as an image. Position it anywhere and rotate it as you see fit: the app also saves a a full-res copy of your original photo as backup.

Eyz Watermark Lite – Aside from what you’d expect from a typical watermark app, eZy Watermark lite (free) can turn signatures and photos into watermarks. Not only that, it saves pictures in three different resolutions and lets you easily share your photos on social networks like Facebook and Instagram.

Android Apps

Add Watermark Free is a free Android app that will not only add the watermark to your pictures but will also allow you to edit it. You can create your watermark with various fonts, colors, and effects such as a shadow. Import as many as twenty fonts, and don’t forget to use your built-in sticker collection to use as a watermark.

Salt can also help you add watermarks to your images, but this is a much simpler app. It doesn’t have as many options when it comes to editing your watermark. If you like an app that keeps things simple, you might want to give this one a try.

With these free to use apps you can easily add watermarks to your pics and share online.
