When something goes sideways
Most Bum Bum problems have boring causes and quick fixes. Here are the ones we actually see, in the order we see them.

“Out of actions”
As a guest, you have used up the lifetime guest allowance; a free account refills you with 75 actions a month. On an account, your monthly bucket is spent: wait for your billing-date reset, or move to Operator and stop counting. Your data is never locked or deleted for this. See What is an action?.
A photo will not read (receipts, posters, meals)
- Flat surface, good light, and the subject filling the frame fixes most failed reads.
- Glare across the important numbers is the usual culprit. Move the light, not the camera settings.
- Test with the sample on the tool's page (Receipt Scanner has one). If the sample reads and yours does not, it is the photo, not the tool.
- Still stuck? Crop the photo square-on with Image Cropper and try again.
A file will not convert or trim
In-browser media tools can only handle formats your browser can play. An exotic codec in an .mp4 costume is the usual suspect; converting the file once on a desktop browser, or re-exporting it from the app that made it, sorts it out. Very large files are also limited by your device's memory, not by us.
Screen Recorder says it needs a desktop browser
Mobile browsers do not let any website capture the screen. Record on a laptop or desktop; the downloaded clip works everywhere after that.
Voice Notes on iPhone behaves differently
iPhone browsers cannot transcribe live, so on iPhone your audio is sent to our server to transcribe instead of happening on-device. The transcript lands in your library the same way. Details on the Voice Notes to Text page.
None of that it? Email hello@leaveittobumbum.com with what you were doing and what the tool said. Error screens in the tools are written to be quoted, so copy the words.
