Question 1

How does Imager compare to Kraken.io for compressing noisy photos?

Accepted Answer

Imager achieves smaller file sizes than Kraken.io, as shown in benchmarks where it compressed images to 4.20M vs. Kraken.io's 24M. However, it requires self-hosting and setup, unlike Kraken.io's SaaS model.

Question 2

How to install Imager on a Linux server using Docker?

Accepted Answer

The README references a Dockerfile; you can build it with 'docker build' and run it in a container. Check the install.md for specifics, but it's command-line based and may need configuration for your environment.

Question 3

Does Imager support PNG and JPEG formats?

Accepted Answer

The README doesn't explicitly list formats, but given its web-focus, it likely handles common ones like JPEG and PNG. Refer to the documentation for a complete list, as this is a common limitation.

Question 4

Can I use Imager to optimize images for a WordPress site?

Accepted Answer

No direct plugins or integrations are mentioned, so you'd need custom scripting or middleware to incorporate Imager into WordPress workflows, making it less convenient than dedicated plugins.

Question 5

Is Imager better than open-source tools like ImageMagick for compression?

Accepted Answer

Imager specializes in maximum compression for web images, while ImageMagick offers broader manipulation features. Benchmarks suggest Imager has superior ratios, but it's more niche in functionality.

Question 6

What's the performance trade-off with Imager's high compression?

Accepted Answer

It prioritizes file size reduction, which may involve aggressive optimization that could affect quality if not tuned properly. The README doesn't detail quality controls, so testing is advised.
