Optimize images without quality loss

We can resize, crop, and (auto-)rotate images, as well as watermark them.

The /image/optimize Robot reduces the size of images while maintaining the same visual quality.

What can I do with this?

Our /image/optimize Robot can be used in combination with other Robots, to create powerful workflows unique to your use case. For inspiration, here is an example scenario, with explanations and code for all platforms, that you can also try live on our website:


This Robot supports parameters such as priority, progressive, preserve_meta_data, fix_breaking_images to influence its behavior. Read all about the technical details in its docs.

Transloadit is a SaaS with a subscription model.

Our /image/optimize Robot counts towards your Plan's data at a normal rate. Assuming an average input image of 0.8MB and an output of 0.48MB, here's what it would approximately cost to optimize images per Plan:

Plan Price Costs per file within your Plan Overage Fee
Sandbox (2GB) Free $0.0
to optimize 1600 images
Startup (10GB) $49/month $0.0061
to optimize the first 8000 images
Small Business (30GB) $99/month $0.0041
to optimize the first 24000 images
Medium Business (150GB) $249/month $0.0021
to optimize the first 120000 images
Enterprise 📞 - N/A

Just like with your mobile plan, pricing goes down when you commit to larger monthly volumes. When you reach your plan's limit, we'll continue to service you, but remind you to upgrade to more cost-efficient plans. This is unless you explicitly set budgets. You can change plans at any time. More info and available plans on our Pricing page.
