## What is ImageResize?

Accurate and effortless. The next generation of ImageResize.
Compare original and resized images side by side.
High-precision, high-quality image resizing with intuitive controls.
Designed with a focus on a smooth, satisfying user experience.


A new generation of ImageResize is here.

ImageResize8 is the next-generation image resizing app, built on the knowledge and feedback gained from the ImageResize series.
By rethinking the design, UI, and image processing from the ground up, and adopting SwiftUI with a new architecture, we refined usability, accuracy, and visual quality to the highest level.

Startup time and interaction responsiveness have been carefully optimized,
delivering a fast and comfortable experience for everyday use.
Battery efficiency has also been improved, allowing the app to be used comfortably even during long sessions.

Instead of checking resize results “by feel,”
ImageResize8 lets you compare original and resized images side by side for precise confirmation.
It strikes a balance between a pleasant user experience and accurate image results.


Simple controls let you:
• Resize images with high quality
• View accurate image information
• Use the app with confidence

From casual everyday use to more advanced needs,
ImageResize8 delivers a smooth and enjoyable image resizing experience.

While respecting the legacy of the ImageResize series,
ImageResize8 continues to evolve as the next step forward.

### 5/5 — 使いやすいです

*2026-02-23*

無料でいいのかってぐらいスマートで使いやすいです。勿論広告はありますが散発的に使う分には全然気になりません

追記：一番よく使っていた600pxぐらいにリサイズする設定がなくなり、不便になってしまいました…。800は大きすぎる、というか300の次が800はガバガバすぎやしませんか？理想を言うなら好きな大きさを入力したい。100px単位でプルダウンから選べるとかでもよい。

### 5/5 — 要望

*2026-02-22*

※追記
アップデートにより要望していた「元の写真削除の有無の設定」と、「アプリ再起動後も前回の保存設定の記憶」を追加して頂けました。ありがとうございます。（追記ここまで）

──

UIが刷新されて少し戸惑いましたが、それはすぐに慣れるかと思います。
以下、要望を書かせて頂きます。

・さらに低圧縮の倍率が欲しい（可能なら0.1倍まで）
・画像を保存するたびに「元の写真を削除しますか？」と表示するのをやめてほしい（都度表示させるかは設定で選択させてほしい）
・アプリ再起動後も前回の保存設定を記憶してほしい。

以上です。
よろしくお願い致します。

### 1/5 — 有料版買ったのに

*2026-02-22, version 8.0.2*

なんでサブスク？広告出てくるならお金返して下さい

### 2/5 — 全くの改悪

*2026-02-14, version 8.0.1*

保存時に解像度の選択が出来なくなり、ファイル名が西暦、月、日時で自動保存出来なくなっています。

### 3/5 — リサイズ画面の劣化

*2026-02-13*

サイズ選択部分が大幅アプデによってスクロール必須になり、UI劣化。
いままでは1画面で必要な操作ができたのになぜスクロールを強制するのか理解に苦しむ。
サブスクを導入するのは自由だけれども使用感を劣化させる上記の変更や画像選択前の絵文字など雰囲気変更が受け付けない。
せっかくシンプルなアイコンと画面だったのになぜ絵文字をつけるのか

### 1/5 — 仕様が変わった

*2026-02-12, version 8.0.0*

以前購入したのに広告が出るようになった。
仕様が変わって写真の保存がめんどくさくなった。

### 1/5 — 共有アプリ候補から消えた

*2026-02-09, version 8.0.0*

アプデしたら写真アプリから共有して使うことができなくて不便になった 最悪

### 1/5 — Crashes. Every. Time.

*2025-10-27*

Every time I try to use, it crashes

### 3/5 — Terrible app

*2025-06-18, version 6.14.0*

What kind of idiot designed this? I select the image, but there’s nothing I can press to get it to appear in the app. I can’t believe it’s this hard to find a decent app to resize images. It should be such a simple task.

### 1/5 — requires FULL access to photo library

*2024-12-20*

the previous version of app worked perfectly with limited access to photo library. Unfortunately that version has been invalidated by developer. The new versions require FULL access to your private photo library, obviously to steal metadata and sell it to advertisers
