설명 An ITHMB file is an Apple photo cache that iTunes and older iPods and iPhones build when photos are synced. It is not a JPEG: each file holds several thumbnails stored as raw RGB565 or YCbCr pixels, with no image header. Contenta Converter decodes all common layouts and saves every thumbnail in the file as its own JPG or PNG.
장점 Can be used to recover photo thumbnails from old iPhone/iPod backups.
단점 Contains only low-resolution thumbnail previews, not the original full-size photos. The .ithmb extension is not recognized by most image viewers.

Frequently Asked Questions about ITHMB

Does an ITHMB file contain my original photos?

No. It holds several small thumbnails that iTunes and older iPods and iPhones build when photos are synced, stored as raw RGB565 or YCbCr pixels. The full-size photos are not in it.

Can I rename an .ithmb file to .jpg?

No. Unlike a THM file, an ITHMB file is not a JPEG and has no image header, so a new extension does not make it open. It has to be decoded.

What does Contenta Converter get out of an ITHMB file?

It decodes all common layouts and saves every thumbnail in the file as its own JPG or PNG, for a whole folder at once.
