## What is Lighten?

Prepare photos, videos and PDFs for sending or uploading. Set size limits and check actual results before saving. Originals stay unchanged.

• Compress and resize. Choose photo or video formats and pixel dimensions. Exact width and height use a crop you adjust and confirm.
• Try PDF compression. See the actual file size and preview the full document before processing.
• Organize upload documents. Group photos and PDFs, merge, reorder and rotate pages, then save each document with its own size target.
• Join, split and cover. Stitch images, adjust overlaps, crop, split long images and add solid covers, blur or mosaic. Preview the full image before export.
• Fewer repeated steps. Share size limits and quality across images and PDFs while keeping each file’s format and dimensions. Reuse saved rules, batch naming and independent media versions.

Results depend on the source, device, settings and available storage. Review conversion changes to motion, HDR or transparency. Blur and mosaic do not guarantee that sensitive information cannot be recovered.

Start free. Pro adds batch tools and more saved rules. Choose a lifetime purchase or an auto-renewable monthly subscription. Local prices are shown before purchase. Monthly renews automatically. Manage or cancel in Apple Account subscription settings; access continues through the paid period. Buying lifetime does not cancel an existing monthly subscription. Existing lifetime purchases remain valid. Eligible purchases support Family Sharing.

Processing runs on device. Lighten does not upload media. iOS may retrieve originals from iCloud or a file provider. Apple handles purchases. No app account or ads. Available in five languages.
