Media files


Photos taken/imported to Epicollect5 will be resized to a resolution of 1024 x 768 px (landscape or portrait, aspect ratio 4:3). They will saved in .jpg format.

When using the web application, accepted formats are jpeg,jpg,png but the resulting image will be resized and saved as jpg.

We found this size to be reasonable for data collection purposes, it is stable across devices with low memory/specs and easily viewable via the web application. Due to modern devices taking pictures at crazy resolutions and with file sizes up to 20MB we had to come up with a consistent solution.

If you want the original, full-size image we recommend taking the photos outside of Epicollect5 and then importing them in Epicollect5 using the image picker when adding an entry. That way the original photo is saved in the device gallery app.

As a side note, the popular app Instagram does use a similar approach.

As technology evolves, we might raise the resolution limits at some point in the future.


Audio files are stored as.mp4 on Android and .wav on iOS.

They are coded as AAC with 44100hz audio sampling.

The maximum file size is 100MB.


Video files are stored as .mp4 files, coded as h.264 on iOS, and on Android it depends on the platform and device, but it is sent always as a mp4 file.

The maximum file size is 500MB.
