What's New in Watermark Adder

5.7.0

October 1, 2026

・ Added an image size limit option to the pre-crop feature ・ Fixed an issue where images could not be saved in WebP format You can now set a maximum image size based on the longest side of the image when pre-cropping. Example: Image size limit set to 1280 px 4032 × 3024 → 1280 × 960 This is useful when you want to intentionally reduce the image resolution for samples or fine-tune the image size to meet the requirements of different publishing platforms.

Beware!

I have tried to cancel this subscription but could not find a way to do so. My account was charged and still I cannot find where to cancel. I am furious because it does not deliver what I was needing. Please beware if you download the trial.

Response from developer

Hello. In version 5.6.0, I added a link in the Settings screen with instructions on how to cancel your subscription. Please feel free to use the free version for now, and if you find yourself needing more efficiency again in the future, I’d be happy to help.

Simple, reliable watermarking that does what I need

I’ve been using this app to add watermarks to my photos, and it’s honestly made the process so much easier. The interface is straightforward, and I like that I can quickly adjust the size, opacity, and placement without digging through a bunch of menus.

I use it mostly for posting on social media, and it’s nice knowing my pictures have my name/logo on them without looking cluttered. I’d love to see a few more font/style options in future updates, but overall it’s solid, fast, and does exactly what it promises.

Response from developer

Thank you for your review and for requesting the option to add fonts. Custom font support has been introduced in version 5.6.0. It does require you to find and download the font you want from the web, but you can now use your favorite fonts in your preferred font weight. You can also download font files from the Google Fonts website by tapping the info button in the font list.

Приложение полностью выполняет все необходимые задачи даже в бесплатном режиме!

動画の入れ方とフォントにつきまして!

とても使いやすいアプリで課金させて頂きました!

しかし確認させて頂きたい点があります!

◾️動画に画像を入れられません。
→文字を全て消して画像を入れて保存してもsampleの文字が何故か入ってしまいます)
◾️フォントが全て同じになってしまいます。種類は選択出来ます。

解決方法がありましたらご教授頂けるとありがたいです!

宜しくお願い致します。

フォントが全て同じになってしまう問題、製作者の方からご回答頂きました!

フォントをダウンロードして使う物という認識を私がしておらず、ただフォントをクリックすると使えると勘違いしておりました💦

無事解決しました。

ご回答頂きありがとうございます!

こちらのアプリ課金して末永く使わせて頂きます。

これからもより良いアプリになるよう願っております。

ありがとうございました!

🔥2026年6月30日追記🔥

課金しているにも関わらず動画を保存する際に強制的に広告が入ります!

ご対応をお願い致します!

動画が保存出来ないのですが、私だけでしょうか?

写真は保存出来ます!

Response from developer

(以前の回答についてフォントを指定してダウンロードするように変更したので削除しました v5.0.0~) 基本的にはネットワーク接続推奨ですが、事前にフォントをダウンロードしておけば、オフラインでもある程度は動作します。ただオフラインですと、起動時・動画生成時など広告が出るタイミングでフリーズする可能性があります。 (20260630回答) 課金プランで広告が出る件、大変失礼しました。ご連絡非常に助かりました。ありがとうございます。 バージョン 5.2.0で、Proプランでも動画保存時に広告が出るバグを修正しました。 (20260707回答) 動画に関して高解像度4k動画(3840*2160)に近いものですと、機種のメモリが足りなくて落ちることがあります。該当せず、「動画の保存に失敗しました」とメッセージが出る場合はメールで動画の一部、カットしたものを送っていただけると早く対応できる可能性があります。mail → dev.bawapps.info@gmail.com お手数かけますが、よろしくお願いいたします。
