"What pixel size does Instagram want?" "My email bounced because the photo was too big." Stop looking it up every time. Image Resizer cuts photo resizing down to two choices: pick a purpose, or set a target file size. There is no width and height to type in anywhere. You don't need to know DPI or aspect ratios. ◆ Just pick a purpose ・Instagram post (portrait or square), Instagram Story, email attachment, web upload, print ・Your photo is fitted to that purpose's dimensions with the aspect ratio preserved ・Photos that are already smaller are left alone — never upscaled ◆ Or just set a file size ・"Keep it under 2MB" — pick a target and quality is tuned automatically to hit it ・One tap for 500KB / 1MB / 2MB / 5MB, or enter your own ・Perfect for attachment limits and upload caps ◆ Many photos, same two taps ・Select several photos and they're all processed together. No separate batch mode to learn ・Every result is listed with its own size reduction, so you can see exactly what happened ◆ See before and after, then save ・Compare the original and the result side by side after processing ・Save to your photo library or hand off through the share sheet ◆ 100% on-device ・Loading, resizing, compressing and saving all happen on your iPhone ・Your photos are never uploaded to a server ・No account required. Works in airplane mode ◆ Made for moments like ・Your post got cropped or looked blurry after uploading ・A marketplace listing rejected your photo for being too large ・A form or email told you "2MB maximum" ・You need to lighten a whole batch of photos at once 【About Premium】 The app is free to use and none of the resizing features are limited. The free version shows ads. Premium — an auto-renewing monthly subscription — removes all ads from the app. ・Payment is charged to your Apple ID account at confirmation of purchase ・The subscription renews automatically unless auto-renew is turned off at least 24 hours before the end of the current period ・Manage or cancel in your device Settings → Apple ID → Subscriptions Privacy Policy: https://hecuhecu.github.io/apps/image-resizer/privacy/ Terms of Use: https://hecuhecu.github.io/apps/image-resizer/terms/

Verdict
The clearest difference is update cadence: SnapSlim at daily against Image Resizer's every 3 weeks. SnapSlim also leads on iOS requirement (13.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
