Image size & video compressor
Only for iPhone
Free · In‑App Purchases
iPhone
Prepare photos and videos for sharing or uploading, right on your iPhone. Set file size, format and pixel dimensions, check the actual result, then save or share. Your originals stay unchanged.
BATCH PHOTOS, ONE WORKSPACE
Select multiple supported photos, including complete Live Photos. Optionally set a total batch size, apply shared requirements or use custom names. Check each result, then save files separately or export a ZIP to Files.
PREPARE TO YOUR REQUIREMENTS
Set your own file size, format and pixel dimensions. Confirm any required crop or conversion before processing. Check the actual result before saving or sharing; the receiving service makes its own final acceptance decision.
EXACT PIXELS, YOUR FRAMING
For exact width and height, adjust and confirm the crop before processing. A maximum long-edge limit scales down proportionally. Compare original and result, then save to Photos, Files or the share sheet.
KEEP WHAT MATTERS
Supported sources can retain Live Photo motion, HDR, location and capture information. Videos keep their full duration and existing sound. When a selected format or setting changes what can be retained, see the effect before continuing. Live Photos use their original format and dimensions when retaining motion; still formats create a static copy.
FREE TO START, ONE-TIME PRO
Export 3 photos and 1 video per day for free, with one saved rule. Lighten Pro unlocks batch processing, more saved rules and no daily export count limit. One purchase, no subscription or advertising. No app account is required.
Processing stays on your device; Lighten does not upload your media. iOS may download originals from iCloud or a file provider. Apple handles purchases and optional ratings. Support depends on the source, settings and device. Actual file size, dimensions and applicable preservation requirements are checked before a result is ready.
Ratings & Reviews
