Convert, resize, or watermark images

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

The /image/resize Robot resizes, crops, changes colorization, rotation, and applies text and watermarks to images.

Our /image/resize 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 convert images per Plan:

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

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.
