Running out of space? Your RAW photos and oversized JPEGs are likely the culprit. Trimage converts and compresses them into lean, high-quality JPEGs so you can reclaim gigabytes — without sending a single photo off your device. Two simple modes, one tap to start: CONVERT RAW → JPEG RAW and DNG files are huge. Trimage turns them into beautiful JPEGs that look the same to your eye but take up a fraction of the space. Perfect for iPhone ProRAW shooters and anyone importing from a camera. COMPRESS LARGE JPEGS Already have big JPEGs eating your storage? Trimage recompresses them at the quality you choose, so you keep the photo and lose the bulk. WHY YOU'LL LIKE IT • See your savings — watch exactly how many megabytes (and gigabytes) you reclaim. • Quality you control — a simple slider from balanced to maximum quality. • Keeps what matters — preserves dates, location, favorites, and optional HDR/wide color. • Your originals stay safe — Trimage never deletes anything automatically. Converted originals are gathered into an album so you can review and remove them in Photos whenever you're ready. • Batch friendly — convert a handful or your entire library. • Built for iPhone and iPad. PRIVATE BY DESIGN Everything happens on your device. Trimage does not collect, upload, or share your photos or any personal data — there are no accounts, no tracking, and no servers. The only thing that leaves is the storage you free up. HOW IT WORKS 1. Pick photos, or let Trimage scan your library for RAW files or large JPEGs. 2. Choose your quality. 3. Tap Convert and watch the space add up. 4. Review your originals in the album and delete them when you're happy. Reclaim your storage today — your future self (and your iCloud) will thank you.
