Image Resizing

I noticed something about image uploads that I’d like to clarify with the community.

Image Resizing on Upload

When I uploaded a JPEG image with a resolution of 3000x2000 pixels, the image had been resized to 1800x1200 pixels on “Uploads”. I’m assuming this was done automatically by Micro.blog.

  • Could anyone clarify the specifications for how and when images are resized after being uploaded?
  • Are image formats such as png, gif, webp, tiff, and pdf processed in the same way as JPEGs?

Your assumption is correct:

  • JPEGs larger than 1800x1800 are scaled down to 1800 (on the largest dimension of the image).
  • PNGs and other formats are currently not processed this way. They are usually left as-is.

I always recommend using JPEGs for actual photos. If the size limitation is causing any problems, let us know and we can consider increasing it.

Thank you for your prompt and clear response!

I appreciate the clarification on the JPEG processing, and the 1800px limit makes sense for most use cases.

This information is very helpful because if I know the specifications, I can design my own image sizes to avoid unexpected resizing runs.

I use WebP for my personal blog from a file size optimization perspective, but I guessed that JPEG would be recommended for Micro.Blog since they also use AI for Alt text generation, etc.

Thanks again for your prompt response to my question!
