## What is JustSize?

Compress photos and videos to any size you need — no need to understand resolution, bitrate or frame rate. Just say "under X MB" and JustSize makes it fit.

■ Just name the size
Enter a target size (MB / KB), or tap a preset: Email 25MB, Discord 10MB, LINE, ID Photo 2MB, Web Upload 500KB. It handles the rest.

■ Warns you before you wait
If the target is too small and quality would clearly drop, JustSize warns you before compressing — and offers fixes you can use: trim the clip, raise the target, or lower the resolution. No more waiting only to find it looks bad.

■ 100% on-device, private by design
All compression, format conversion and metadata editing happen on your iPhone. Your photos and videos never leave the device and no network is required.

■ See what's hidden in your photos
View full EXIF metadata. When a photo contains GPS data, see the capture location on a map. Remove location only, or clear all metadata in one tap — protect yourself before you share.

■ More handy tools
· Image conversion: HEIC ↔ JPG / PNG
· Video conversion: MOV → MP4 (H.264 / HEVC)
· Batch processing with per-file results
· Total space-saved stats

■ Buy once, no subscription
Free tier compresses 3 files per day. A one-time $7.99 unlocks everything: unlimited compressions, unlimited batch size, all format conversions. Pay once, keep it forever, free updates. Honest pricing — no subscription traps.
