We are a Swiss Army knife for your files

Transloadit is a service for companies with developers. We handle their file uploads and media processing. This means that they can save on development time and the heavy machinery that is required to handle big volumes in an automated way.

We pioneered with this concept in 2009 and have made our customers happy ever since. We are still actively improving our service in 2024, as well as our open source projects uppy.io and tus.io, which are changing how the world does file uploading.

Convert an image from ICO to TIFF

Transloadit's API makes light work of changing the format of images from ICO to TIFF. Whether we need to convert directly as your users upload, or processing entire media libraries in the background, you can use 🤖/image/resize and set its format parameter to the appropriate value.

In this case "tiff" to convert to Tagged Image File Format images. We'll accept any image as input, no need to define that, but in this demo, we'll be uploading Microsoft icon images (ICO).

Transloadit supports over 40,000 image conversion format pairs. Combined with 72 other Robots, this easily makes us the most versatile conversion API on the planet.

⚠️ It seems your browser does not send the referer, which we need to stop people from (ab)using our demos in other websites. If you want to use the demos, please allow your browser to send its referer to us. Adding us to the allowlist of blockers usually helps.

Step 1: Handle uploads

We can handle uploads of your users directly. Learn more ›

":original": {
  "robot": "/upload/handle"
}
🤖/upload/handle
This bot receives uploads that your users throw at you from browser or apps, or that you throw at us programmatically

Step 2: Convert images to TIFF

We can resize, crop, and (auto-)rotate images, or apply watermarks and other effects, and much more. Learn more ›

🤖/image/resize
This bot resizes, crops, changes colorization, rotation, and applies text and watermarks to images

Step 3: Export files to Amazon S3

We export to the storage platform of your choice. Learn more ›

"exported": {

  ],
  "robot": "/s3/store",
  "credentials": "YOUR_AWS_CREDENTIALS",
  "url_prefix": "https://demos.transloadit.com/"
}
🤖/s3/store
This bot exports encoding results to Amazon S3
Since this is a store Robot, be sure to use Template Credentials so that any sensitive data is encrypted and stored in our database, making sure that they’re never exposed to any end-user.

So many ways to integrate

Transloadit is a service for companies with developers. As a developer, there are many ways you can put us to good use.
  • Bulk imports

    Add one of our import Robots to acquire and transcode massive media libraries.
  • Handling uploads

    We are the experts at reliably handling uploads. We wrote the protocol for it.
  • Front-end integration

    We integrate with web browsers via our next-gen file uploader Uppy and SDKs for Android and iOS.
  • Back-end integration

    Send us batch jobs in any server language using one of our SDKs or directly interfacing with our REST API.
  • Pingbacks

    Configure a notify_url to let your server receive transcoding results JSON in the transloadit POST field.
