-Resolution enhancement
With Upscale 4x, you can enlarge an image and increase its resolution by 200%, 400%, or 800%.

### 5/5 — 값어치 이상!! 👍👍👍

*2026-08-02*

요즘 화질만 올리는 업스케일링
사이트들 다 월간 구독에 비싸거나 가격대비 성능은 품질이 좀 떨어지는 편인 것도 많았는데, 우연찮게 찾은 이 앱은 1회성 결제인데도 좋네요!! 진짜 유레카 외쳤습니다 ㅎㅎ 잘쓰겠습니다 감사합니다!

### 3/5 — 不好用

*2026-07-28*

这个软件呢他这个修复特别诡异呀，我找了几张照片去修复一整个脸就是像鬼，我的妈呀，特别诡异，特别搞笑，很阴间的那种，然后呢，我就去修复了一个动漫的一张图，那个修复的还挺好，但是呢，结果我说保存，他说要什么要解锁完整版，我就没有继续往上点了，我就知道要付费了，然后就是可以不用下，因为要付钱我去我没钱，还有那个人脸真的很奇怪

### 5/5 — Норм

*2026-06-05*

Норм

### 3/5 — Super!!!

*2026-04-05*

Ca marche et c’est gratuit 
Seule réserve mais pas très grave:
Sauf erreur de ma part, l’amélioration n’est pas disponible en 8x au moins pour la version gratuite, et parfois on ne voit pas vraiment la différence en 4x. Pensez à le rendre possible en limitant par exemple la quantité :
1 par semaine/ou au pire 1 par mois
Ça serait top et donnerait envie de passer au payant si 8x efficace
Sinon bravo 👏👏👏👏👏👏

### 5/5 — Exceptional

*2026-03-02, version 3.3*

Professional Quality

### 1/5 — There is no free use

*2026-02-27*

You cannot use the simple feature without taking the « pro » version of the application, so you don’t have an application at all, it’s not correct to make you believe that you can use at least a simple mode, the most basic option is behind a paywall

### 5/5 — Love it

*2026-02-14, version 3.3*

Use this app on a daily basis, thank you

### 5/5 — No Subscription Just One Time Fee

*2026-02-11, version 3.3*

Thank you for making something that people will actually want to pay. $4 one time fee is very reasonable and the app is very good!

### 1/5 — ужас!!!

*2026-01-25*

не приложение а ужас какой-то, мало того что грузило 10 минут, так ещё и не дают сохранить, говоря купить премиум.

### 5/5 — G

*2026-01-20, version 3.2*

Good
