We are a Swiss Army knife for your files

Transloadit is a service for companies with developers. We handle file uploads and media processing for them. This way they can save on development-time and heavy machinery that’s 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’re still actively improving our service in 2017, as well as our open source projects uppy.io and tus.io, that are changing how the world does file uploading.

Encode video to HEVC

High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard, one of several potential successors to the widely used AVC (H.264 or MPEG-4 Part 10). In comparison to AVC, HEVC offers about double the data compression ratio at the same level of video quality, or substantially improved video quality at the same bit rate. It supports resolutions up to 8192×4320, including 8K UHD.

In most ways, HEVC is an extension of the concepts in H.264/MPEG-4 AVC. Both work by comparing different parts of a frame of video to find areas that are redundant, both within a single frame as well as subsequent frames. These redundant areas are then replaced with a short description instead of the original pixels. The primary changes for HEVC include the expansion of the pattern comparison and difference-coding areas from 16×16 pixel to sizes up to 64×64, improved variable-block-size segmentation, improved "intra" prediction within the same picture, improved motion vector prediction and motion region merging, improved motion compensation filtering, and an additional filtering step called sample-adaptive offset filtering. Effective use of these improvements requires much more signal processing capability for compressing the video, but has less impact on the amount of computation needed for decompression.

At Transloadit you can encode to HEVC using one of our encoding presets which will automatically set all required FFmpeg parameters.

1. Receive files sent by users or apps

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

34 MB · 22s · 1280 × 720

We handle uploads that your users throw at you from browser or apps, or that you throw at us programatically:

tl.addFile('file', './360s10f.mp4')

2. Transcode videos to HEVC (H.265)

Transloadit offers a variety of features to reduce video size while maintaining quality, as well as add effects like watermarks. Learn more ›

hevc_encoded: {
  use: [':original'],
  robot: '/video/encode',
  preset: 'hevc',
}
/video/encode Robot
This bot encodes, resizes, applies watermarks to videos and animated GIFs

3. Export files to Amazon S3

Transloadit is happy to export to whatever storage solution suits you best. Learn more ›

exported: {
  use: ['hevc_encoded',':original'],
  robot: '/s3/store',
  bucket: 'demos.transloadit.com',
  bucket_region: 'us-east-1',
  key: 'YOUR_AWS_KEY',
  secret: 'YOUR_AWS_SECRET',
}
/s3/store Robot
This bot exports encoding results to Amazon S3
Since this is a store robot, be sure to use Templates so that any credentials are encrypted and stored in our database, making sure that they’re never exposed to any end-user.

Try it yourself

This live demo is powered by Uppy, our open source file uploader that you can also use without Transloadit, and tus, our open protocol for resumable file uploads that is making uploading more reliable across the world.

Full code used

This demo uses :original, a magic word to identify uploads that Transloadit accepted.

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.
  • Backend 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.
