Efficient-Compression-Tool VS PhotoPrism

Would be interesting to see how all those jpegs fared if run though ECT (https://github.com/fhanau/Efficient-Compression-Tool). I’ve found it can save a surprising amount of space sometimes.

Ah, I misunderstood you there, yes you can build it from source but there are also Windows binaries available on https://github.com/fhanau/Efficient-Compression-Tool/releases/

Did you think about adding support for newer image formats? Video shouldn't be a problem because you already support .mkv and AV1 works within it. How would implementation work? Does ES-DE use libraries from the OS and makes this support easier for that? My biggest gripe are those big .png files. I optimized them with ect but it won't be as good as newer formats can be.

If png size is a concert of yours: Efficient Compression Tool

There are a myriad of PNG (and in general DEFLATE) optimizers and pingo hosts its own benchmark [1]. I believe ECT [2] is the only tool comparable to pingo in terms of compression ratio and speed. But pingo still lacks a license statement and it's even unclear whether you can use this for any purpose at all, probably because it is still "experimental", so if you don't like that you can try ECT instead.

> One thing I didn't check is that you might pay that in decoding time, I've never seen anybody talking about that though.

PNG and in general DEFLATE-based formats are mostly free from this concern because they are comparably simple. The maximum "overhead" you can intentionally trigger is a very large LZ77 window and a very deep Huffman tree; the former is however capped to 32 KB in DEFLATE, and the latter will mostly result in an inferior compression (a long prefix code means a larger file).

I personally prefer ECT, since that gave me the best results when I tested it several years ago.

ECT is the new stuff that is much faster and more efficient than zofpli

Efficient Compression Tool Basically the best FOSS for lossless compression for .png and .jpeg, although not the quickest.

I get the same issue. However, it seems that using ECT on the images fixes the issue: https://github.com/fhanau/Efficient-Compression-Tool

I have been using https://www.photoprism.app for a couple of years, and it works better than expected, with the latest updates it's actually quite fast and the face tagging works reasonably well.

For self-hosting, there's Photoprism[1] as well.

Ente's strength lies in end-to-end encryption[2] and its cloud[3] offering so you don't have to worry about reliability.

So if self-hosting is what you're after, Immich, Photoprism and Damselfly (TIL!) are perhaps better designed to serve your needs.

For quite a while I'm also in search for a solution which allows me to share galleries with my family, without having to ask them to jump through hoops in order to access them.

After some searching I'm now testing photoprism [1] which is a fantastic application, especially for self-hosting of photos. There's no mobile app for it (yet) and user-management is just starting to get implemented, but it shows alot of promise. Unfortunately not yet enough for putting it on the tablet of my granny but one can hope (and donate!)

Either way, I'm afraid that building a good mobile gallery app is an equally large task, after all the best solution would be to replace the users' native gallery-app with an equivalent that also supports custom Online-Galleries...

out of curiosity, why no sort-of-established pkg and internal dirs? What do you think of https://github.com/photoprism/photoprism structure?

Thank you!

Ente was first a piece of hardware, then a self-host-able project, but we had a hard time monetizing both, which lead to the E2EE pivot.

TIL about TagSpaces, thanks!

Our server can be open-sourced, but we're unsure of the value E2EE will provide, with services like Photoprism[1] and Immich[2] already doing a good job of serving customers who prefer to self host. In this context E2EE might become a constraint, rather than a feature.

Ive seen github issues like this one https://github.com/photoprism/photoprism/issues/907 in which it is implied that this is very very difficult.

Hi. I want to implement an image server similar to Photoprism using ImageAI to tag images based on objects and context. However I don't want to spend to much time working on the frontend, at first I were thinking about using Danbooru and use Flexbooru or the web interface on my phone. But it doesn't have any encryption or password protection (since the purpose of it is to be used as a public image board).

https://www.photoprism.app in Docker.

PhotoPrism[0] and some ugly plumbing[1] to semantically tag all images in the gallery.
