I’ve searched around and can’t find this but it seems like someone must have created this already. I am hoping to find a self-hosted image resizer app. I frequently need to take photos from my phone (etc…) and make them small enough to post online.

For instance, my lemmy instance (lemm.ee) only allows images in posts if they are smaller than 500KB but my phone’s photos are always larger than that.

In a perfect world, I could just browse to a local server app, upload an image, select a size to resize it to, hit Go and then download the smaller image. It doesn’t have to allow any other editing and it shouldn’t store images long-term. I want to self-host so I don’t have to upload my images to random web sites I know nothing about.

I would be happy with a FOSS desktop app I can install in linux too, but then I couldn’t access it from my phone. The Android apps I found for this either look scammy or include tons of ads.

Anyone know of such a thing? Thanks!

EDIT - UPDATE:

Thank you for the great suggestions. I’ve installed Image Toolbox on my Android phone and that looks great. It both has a ton of tools but also makes this resizing task very straightforward. Not sure how I never found that before.

But for my desktop, I started writing a PHP app to run in my existing nginx web server. It runs the suggested ffmpeg command under the hood, and since I am the only user on this server, this works very well for me.

That’s working now so I am going to tweak a few things and then use it for a while. (Before anyone asks, I started based on the Python recs here, but couldn’t get it working (PIP couldn’t add Flask because PIP couldn’t find PIP???) and so switched to PHP since my local server was already using that from another home-made app. This (PHP) was not as hard as I was afraid it would be, with help from Duck Duck Go’s AI chat bot.

I used my php app to shrink this file!

Thank y’all - this is resolved now.

      Do you use a gallery app you like? I’m kind of sick of Google photos. I always have to “save a copy” when editing and it also separates my photos in a dumb way.

      I’d like something simple that isn’t trying to sell me something (storage)

    I recently saw a self-hosted imgix/cloudinary alternative. I thought I starred it on gh, but apparently not and I can’t remember the name.

    Edit
    I think this was it:
    https://github.com/imgproxy/imgproxy

    But also, on a second read of your post, I now realize what you are looking for is right here:
    https://squoosh.app/

    It’s open source and it’s entirely client-side. It allows you to customize the settings to compress your image to the file size and format you need and maintain as much as the quality as possible. I can’t think of a simpler solution that works across all your devices.

        I loved that app for like a year and yes, it was perfect. I don’t know what changed but about 6 months ago, when I upload images to it, they were black rectangles and so it wouldn’t shrink my images. No idea what caused that, I searched around and could not find a resolution so I moved on.

        But also, it’s owned by GOOG and that’s a downside for me.

        https://github.com/GoogleChromeLabs/squoosh

        However, Squoosh utilizes Google Analytics to collect the following:

    Basic visitor data.     <-- what does this mean?
    The before and after image size value.
    If Squoosh PWA, the type of Squoosh installation.
    If Squoosh PWA, the installation time and date.

        I should see if I can download the code, strip out their surveillance and then use it locally from there. Thanks for the tip!

    that would probably be better as an app, rather than a hosted service.

    I run picsur. It’s not an image resizer like that. It’s like Imgur, but self-hosted and can take size arguments as part of the query. I use it to host images for a markdown based blog and keep the sizes under control.

    On a side note, I recently started noticing so many sites that use full sized images regardless of the actual size it shows up on screen.
