You can reposition the image to your liking in the available space Choose from three output formats: JPG, HEIC, and PNG. JPG and HEIC formats allow output quality to be reduced and getting a smaller file size Rezzize allows for batch processing (up to 100 images).

Verdict
The clearest difference is review sentiment: Rezzize at 100% against Image Size's 71%. Rezzize also leads on iOS requirement (14.0 vs 18.0). Image Size's advantage is ratings volume (30K vs 33) and rating (4.7 vs 4.4). On price, update cadence, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Image Size sells 3 one-off in-app purchases and Rezzize sells 4 in-app purchases, starting at $1.99 per year. Whichever you choose, the download price is not the number that matters.
Image Size holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: Image Size has 30K ratings behind it against 33, so its average is the more settled of the two. Written reviews complicate that: 71% of Image Size's written reviews are positive against 100% of Rezzize's, so the app with the better star average is not the one people write more warmly about.
Image Size ships an update fortnightly, Rezzize every 3 weeks. The most recent releases landed on September 25, 2026 and September 17, 2026 respectively.
