Can I use lambda to compress images under a bucket? I can get the images under a particular bucket visa listObject. How do you compress these returns and write it in another bucket?

Yes, you can absolutely use lambda. Try this library: aws-lambda-image-compressor
AWS lambda function to compress and resize images
This is a Lambda Function which resizes/reduces images automatically. When an image is put on some AWS S3 bucket, this function will resize/reduce it and save it into a new bucket. I have used it in the past and I loved it.
Usage
- edit lambda-config.js file and assign name, description, memory size, timeout of your lambda function.
- edit .env file with your AWS access data
- npm install
- gulp deploy
You can also try this other library which is more popular in the crowd - aws-lambda-image
If you really want to create something of your own and want a good start.
I would recommend these 2 articles that explain it very well -
Image conversion using Amazon Lambda and S3 in Node.js

If you are fine to use Amazon API Gateway then u can follow this AWS Compute Blog -

Hope this was useful.
