Context

Hi! I’m Samir Saci, Supply Chain Engineer, Data Scientist based in Paris, and founder of LogiGreen.

I built this workflow for an agency specialising in e-commerce to automate the daily compression of their images stored in a Google Drive folder.

This is particularly useful when managing large libraries of product photos, website assets or marketing visuals that need to stay lightweight for SEO, website performance or storage optimisation.

> Test this workflow with the free tier of the API!

Who is this template for?

This template is designed for:

• E-commerce managers who need to keep product images optimised
• Marketing teams handling large volumes of visuals
• Website owners wanting automatic image compression for SEO
• Anyone using Google Drive to store images that gradually become too heavy

What does this workflow do?

This workflow acts as an automated image compressor and reporting system using Tinify, Google Drive, and Gmail.

1. Runs every day at 08:00 using a Schedule Trigger
2. Fetches all images from the Google Drive Input folder
3. Downloads each file and sends it to the Tinify API for compression
4. Downloads the optimised image and saves it to the Compressed folder
5. Moves the original file to the Original Images archive
6. Logs: fileName, originalSize, compressedSize, imageId, outputUrl and processingId into a Data Table
7. After processing, it retrieves all logs for the current batch
8. Generates a clean HTML report summarising the compression results
9. Sends the report via Gmail, including total space saved

Here is an example from my personal folder:

Here is the report generated for these images:

P.S.: You can customise the report to match your company branding or visual identity.
