Downsizer for Mac

Photos

Choose Open Photos, select one or more photos, or drag them into the window. Resize a single photo by pixels, percentage, centimeters, or inches. Multiple photos resize together by percentage while preserving each photo’s aspect ratio. Export as JPEG, HEIC, PNG, WebP, or PDF.

Video

Choose Open Video or drag in a video. Select resolution, quality or target size, H.264 or HEVC, MP4/MOV/M4V, and whether to keep audio, then export.

Originals and metadata

Exported files are new files with the current creation date. Downsizer preserves embedded photo metadata where the output format supports it. After a successful export, you may keep the originals or move them to Trash.

Free and Pro

Free includes batches up to 5 photos, JPEG/HEIC/PNG, and one video export. Downsizer Pro is a one-time purchase that unlocks batches up to 50 photos, WebP/PDF, and unlimited video exports. Use Restore Purchase with the same Apple Account if Pro is not recognized.
