Compress

Shrink it
instead of deleting it.

Drop in videos and photos, or send the biggest ones straight from a scan. Videos go through the Mac's own hardware encoder, and your originals stay exactly where they were.

DiskBuddy Compress: a grid of screenshots and a screen recording, each showing its new size and saving, beside the compression settings.

385 MB smaller. From ten files.

Videos often come out 50 to 90% smaller, as MP4, MOV, GIF or WebM; here a 390 MB recording became 4 MB. Photos already as small as the setting allows are left as they are.

DiskBuddy Compress result: 385 MB smaller, from 398 MB before to 13 MB after.

Pick the quality, or the size you need.

Smaller, balanced or best. Keep each photo's format or convert to JPG, PNG, WebP, AVIF or HEIC. Copies go into a Compressed folder beside the original.

How it works

Shrink instead of delete

A 4 GB screen recording often comes out a few hundred megabytes and looks the same. Send the biggest videos and photos straight from a scan, or drop files anywhere on the screen.

Every format that matters

Videos as MP4, MOV, GIF or WebM, in HEVC or H.264. Photos as JPG, PNG, WebP, AVIF or HEIC. Each file shows its preview, its size before and after, and the saving.

Quality, size or a target

Pick Highest down to Acceptable, or a target file size and let DiskBuddy find the quality that lands under it. Resize to 4K, 1080p, 720p, a percentage or any edge you name.

Originals kept

Compressed files are saved as new files beside the originals, or in a folder you choose. Turn on Remove originals and they go to the Trash afterwards, never deleted outright.

Encoded on your Mac. Nothing is uploaded, ever.

Questions about Compress

Does compressing a video lose quality?

At High and Highest the difference is hard to see; the savings come from a modern codec and a sensible bitrate. Lower settings trade some detail for a smaller file.

Are my files uploaded anywhere?

No. Everything is done on your Mac with its own encoders. Nothing is sent to a server.

Can I make a GIF from a video?

Yes. Choose GIF as the output format. The frame rate follows the quality setting, and the GIF is sized to stay reasonable unless you set a resolution.
