How much does change.photos cost?

There's a free plan with 50 images per month, a Basic plan at $10 per month for 1,000 images, and a Pro plan at $25 per month for 5,000 images. Every tier includes unlimited API calls and storage.

Do I need coding skills to use it?

Yes. change.photos is an API product, so you need to make HTTP requests from your own code or backend. If you want a click-and-drag editor, this isn't the tool for that.

Which image formats are supported?

You can output JPEG, PNG, or WebP, and the input can be any of those formats. The API defaults to JPEG if you don't pass a format parameter.

Is there a free trial or free plan?

There's a permanent free plan rather than a time-limited trial. It covers 50 images a month, which is enough to test the API in a real project before committing to a paid tier.

Can it process images in bulk?

Yes. Since each request transforms one image, you can loop or queue requests to handle large batches. There's no separate batch endpoint, but unlimited API calls mean the quota is the only real ceiling.

What happens if I go over my monthly image limit?

Requests stop once you hit your plan's image count, and the API returns a rate limit error. You can upgrade to a higher tier to raise the monthly cap.

About change.photos

What Is change.photos

change.photos is a web-based image transformation API for resizing, processing, and shrinking images. You send it a photo URL plus a set of parameters, and it returns a link to the finished image. There's no photo editor to learn and no desktop software to install. The whole product is a REST endpoint called /api/change.

The main problem it solves is repeatable image work at scale. If your app needs every uploaded photo resized to the same width, converted to WebP, and compressed before it hits storage, you'd otherwise wire up a whole image library yourself and keep it patched. change.photos handles that as a photo API for developers, and you can call it from any language, which is where bulk image processing usually starts to hurt.

The biggest limit is scope. This is a transformation API, not a generation tool. It won't remove backgrounds, swap faces, or invent new pixels. If you need generative editing, you'll need a different platform. And every image has to be reachable by URL, so local files need to live somewhere public first.

Getting Started

Create a free account at change.photos and grab an API key from your dashboard.
Send a POST request to https://change.photos/api/change with your key in the Authorization header and Content-Type: application/json.
Pass the url of the image you want to transform, plus any parameters such as width, height, format, or quality.
Read the url field in the JSON response, which points to your transformed image.
Track usage against your monthly image quota, then upgrade the plan when you outgrow it.

Key features

One Endpoint for Every Operation

All nine operations run through the same POST /api/change call. This image resizing API is really one image manipulation API for resize, rotate, flip, compress, blur, sharpen, grayscale, tint, and convert, all sharing one request shape. You learn the pattern once, and it keeps your integration short and readable.

Precise Resizing with Fit Modes

The width and height parameters accept pixel values, and the fit option controls how the image maps onto them. You can pick contain, cover, fill, inside, or outside to avoid the stretched look that naive resizers produce. One parameter line usually covers an entire thumbnail setup.

Format Conversion and Quality Control

This image compression API lets you output JPEG, PNG, or WebP and set quality anywhere from 1 to 100. It's the part that matters for page speed, because converting a PNG screenshot to WebP at a lower quality can cut file size a lot. The API defaults to JPEG at quality 80 if you don't specify.

Rotation and Flipping

The rotate parameter takes any angle from -360 to 360 degrees, and flip and flop mirror the image vertically and horizontally. It's handy when user uploads arrive sideways and you want to correct them without a manual pass.

Blur, Sharpen, Grayscale, and Tint

Blur accepts a sigma value between 0.3 and 1000, so you can go from a subtle softening to a heavy mosaic effect. Sharpen and grayscale are simple booleans, while tint takes an RGB object for color grading. Together they cover the light edits most apps need.

Usage-Based Pricing with a Free Tier

The free plan gives you 50 images a month with unlimited storage and unlimited API calls. Basic runs $10 a month for 1,000 images, and Pro runs $25 a month for 5,000. Only the number of image transformations changes between tiers, so nothing gets feature-locked.

Pros and cons

Pros

Setup takes minutes because everything goes through one POST endpoint with a consistent parameter set.
The free tier includes unlimited API calls and storage, so you're only capped on processed images.
WebP output plus quality controls make it easy to cut image weight for faster pages.
All paid tiers unlock every operation, so you never hit a feature wall after upgrading.
Blur, tint, and fit modes cover common editing needs without adding another service.

Cons

There's no visual editor or mobile app, so it's built for code rather than hands-on tweaking.
Transformation only, no background removal, generation, or AI object editing, which means creatives still need a separate tool.
Images must be available at a public URL, so private local files need to be hosted first.
The free plan's 50-image monthly cap runs out fast if you're processing real traffic.

Frequently asked questions

It transforms images through an API. You send a photo URL and parameters like width, format, or blur, and it returns a URL to the processed image. It handles resizing, compression, conversion, and light effects, not AI generation.
