Uploading learner work: acceptable file formats, size limits and browsers

Before you upload anything, we recommend you use one of these browsers for the most reliable experience:

• Google Chrome
• Microsoft Edge
• Safari

Make sure you're using the latest version. Older versions can cause problems with uploads or stop some features from working properly.

You must upload learner work in a file format our systems support. Check your files before you upload them to avoid errors.

If your files aren't already in the right format:

• you can use free file-conversion software available online
• always convert a copy of the file and keep the original as a backup

Please note: If you try to upload an unsupported file type, you may see an error during upload or the system may reject the file later.

What are the acceptable file formats?

For video evidence, your files must use:

• H.264 codec for video
• AAC codec for audio

Videos created with other codecs (such as H.265) won't work and will be rejected. If you need to, use video conversion software to change the codec before you upload. As with file formats, convert a copy and keep the original file safe.

We specify this because H.264 works almost everywhere, reliably, so examiners shouldn't have any issues accessing or watching the video.

If you're uploading evidence for T Level qualifications, the following file formats are specific to T Level delivery, and we also accept them as exceptions. You can upload:

• Packet Tracer files
• .mpp
• .pod
• .mpx

All other guidance in this article still applies, including file size limits and browser requirements.

Each individual file must be no larger than 3GB. This limit applies per file, not to the total size of all files for a learner.

If a learner's evidence includes multiple files, each one can be up to 3GB.

If a file is too large, you can:

• reduce the video or image resolution
• split the file into smaller parts
• reformat or repackage the file so it stays within the limit

You don't need ultra-high-definition video for assessment. Aim for clear and readable evidence without making files larger than they need to be.

• Check any subject-specific guidance for your qualification in case there are extra requirements
• Keep copies of everything you upload, as we can't return files once they're submitted
• If something isn't compatible, the system will usually tell you at the point of upload or may reject it later
• Using a Mac or other non-Windows device? We've reviewed this, and these devices will allow you to save in the different file types stated. 
  • Please ensure files are saved in one of the listed file types as listed in the 'Upload files in an accepted format' section above.  

Following this guidance helps your learner evidence upload smoothly and avoids delays in the assessment process.
