LEARN MORE

Thumbor is a smart imaging service. It enables on-demand crop, resizing and flipping of images. It features a very smart detection of important points in the image for better cropping and resizing, using state-of-the-art face and feature detection algorithms (more on that in Detection Algorithms).

No more headless bodies

With the most advanced face detection technology, Thumbor ensure you to have the best image crop possible. Everytime a face is detected, it will crop the image around it, making sure the most important parts of the picture are preserved.

Images everywhere

Thumbor allows users to store and load images from anywhere needed. It's really simple to implement a new loader or storage. It comes packaged with file, http, redis and mongo implementations for loaders and storages. Just pick what makes sense for you or implement your own.

Filter to enhance

Thumbor has support for image filters. Filters usually apply some post-processing to the images and they can be chained and applied in order. Thumbor's extensible nature allows you to write your own filters, but it comes with some pre-packaged filters of its own. Brightness, contrast, grayscale, red-eye and blur are a few samples.

Thumbor supports webp

WebP is a new format for lossy and lossless images that compresses a lot better than jpeg and png. Thumbor allows users to specify that browsers that support WebP automatically get it. This can have a dramatic increase in the performance of your website. Besides WebP, Thumbor also uses some tactics to reduce the file size even further.

Thumbor made our lives better. We moved to Thumbor and now, we cannot live without it
Properati
Thumbor allows Yipit to iterate quickly on new designs. Our initial Thumbor installation took less than an hour to set up, and we haven't had to spend much time thinking about it since then.
Yipit
With Thumbor we can quickly iterate and make changes to our layouts serving the optimal image format each time. Thumbor is awesome!
oony
Thumbor helps us in decoupling applications from our storage backend. We were able to move from a centralized NFS storage to a distributed storage with a simple plug-in. Thumbor is really comfortable for Ops.
Viadeo
We use Thumbor to generate mobile thumbnails that requires dealing with masks, feature trimming, transparent images, and replacing backgrounds. Thumbor made this possible and simple.
