RollDiet: Photo Video Cleaner

Compress & Trim Large Videos

Free · Designed for iPad. Not verified for macOS.

Videos take up the most space. Find your biggest ones, tap Edit, and keep only the part you want or shrink to 1080p. Your photos never leave your device. Videos are usually what fills up your storage. RollDiet finds your biggest videos and makes them smaller without losing the moments you want to keep. Then it helps you clear out duplicate, burst and blurry photos with a swipe. ■ Make big videos small “Large videos” lists your videos biggest first, with size, length and resolution. Tap “Edit” on the right of any video to open the editor straight away: • Keep only what you need: keep one or more parts and drop the rest. Nothing is re-encoded, so it’s quick and the picture and sound stay the same. • Shrink: keep the whole video and re-create it at 1080p. A 4K video becomes about a quarter of the size. • Trim and shrink: both at once, for the smallest file. You see the new size before anything is saved, and you can cancel at any time. Afterwards, the original moves to Recently Deleted, where it stays for 30 days. To remove videos you no longer need, tap “Select”. ■ Swipe to sort photos Swipe left to mark a photo for deletion, right to keep it, and tap Undo if you change your mind. Bursts and similar shots are grouped with a suggested keeper; one tap marks the rest. When people are in the shot, the keeper is chosen by how their faces came out. ■ Reclaim space without deleting photos Re-create large photos at a smaller size, convert older JPEG photos to HEIC (about half the size), and turn Live Photos into still photos to drop the video part. Screen recordings and RAW files are listed separately. For large photos, the app shrinks the first few and shows the real saving before doing the rest. ■ Knows what to keep Screenshots are sorted by what’s in them: codes and tickets, receipts, conversations and others. Codes and receipts stay out of the suggestions, and blurry photos of documents or receipts aren’t treated as bad shots. Photos that look like they were taken through a smudged lens get their own group, so you know the cause. ■ See the space before you delete The app shows how much storage you’ll get back. Deleting goes through the system’s own confirmation, and items stay in Recently Deleted for 30 days. ■ Private and fast All analysis happens on your device. Your photos and videos are never uploaded or sent anywhere. There’s no limit on the number of photos, and even with 30,000 photos the first results appear within seconds. Requires iOS 17 or later. Smudged-lens detection and screenshot sorting require iOS 26 or later. Support: rei12jii@gmail.com

Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

• Every video in “Large videos” now has an Edit button on the right. Tap it to go straight to keeping only the part you need or shrinking the video. • On iPad, the video editor now opens at full height, so the trim handles are easy to reach. • Clearer wording in several languages, plus smaller fixes.
