Современные форматы изображений или почему мы до сих пор на JPEG?

Формат JPEG появился в 1992 году и стал де-факто стандартом хранения фотографий в интернете. Спустя более 30 лет появляются всё более эффективные и продвинутые альтернативы: WebP, AVIF, JPEG XL и другие. Однако даже в 2025 году JPEG продолжает доминировать. Почему так происходит, несмотря на очевидные преимущества новых форматов? В этой статье мы проведем обзор форматов и разберёмся в причинах.

So I have hundreds of videos of ~1 minute recorded from my phone ~10 years ago, and they generally don’t have that great compression, nor they are stored in a modern and advanced video format.

For archiving purposes, I want to take advantage of my workstation’s mighty GPU to process them so that the quality is approximately the same, but the file size would be strongly reduced.

Nevertheless, compressing videos is terribly hard, and way more complex than compressing pictures, so I wouldn’t really know how to do this, what format to use, what codec, what bitrate, what parameters to keep an eye on, etc.

I don’t care if the compression takes a lot of time, I just want smaller but good looking videos.

Any tips? (Links to guides and tutorials are ok too)

Also, unfortunately I am forced to use Windows for this (don’t ask me why 🫠), but I know nothing about Windows because I hate it. Practical software suggestions are very much welcome, too!

Fetch Apple iPhone photos to your Linux computer (2)

In part 1 photos from an Apple iPhone were copied to a Linux computer with LocalSend. In that case the resulting files will be having the HEIC file extension. That is OK for viewing the photos with image viewers that support the heic file extension.

Converting to png or jpg may be useful if you want to upload the photos to the Internet.

On Linux :

If you want to use a batch operation on a lot of files on the command-line,

or want to use a GUI application, see for example here : Ubuntuhandbook site,

or use DDG, Startpage or a good search engine to search for something like :

p.s.

If you are interested in trying out the libimobiledevice method like mention in part 1,

see here the Arch Linux wiki entry to get some hints about how to apply it for your Linux distribution. I’ve written that it can be confusing because you cannot delete files and only copy but the interesting thing I forgot to mention is that with this method you can see a lot more of the file structure and other files on iOS.

Der reduzierte Speicherverbrauch von HEIF im Vergleich zu JPG ist im Praxistest schon echt krass. Bei einer Mischung aus Handyfotos und Fotos der Spiegelreflex habe ich 60% Reduzierung ohne sichtbaren Qualitätsverlust erreicht. Überlege mein Fotoarchiv komplett zu konvertieren 🤔 Bei Videos habe ich schon alles auf h265 gewandelt...

Was nutzt ihr als Speicherformat für Fotos?
