My file doesn't work — the five most common causes
Troubleshooting walk-through for when a file from Web Manifest Generator doesn't behave the way you expect.
Generating a file sounds like it should require an app — and historically it did. Web Manifest Generator runs the same thing in your browser tab, with one tap and no signup.
Open the tool: Web Manifest Generator — No upload, no signup, no daily limit.
Why your file doesn't work — five most common causes
- Source data too long — exceeds the format's encoding capacity. Web Manifest Generator warns at the threshold; pay attention to the warning.
- Wrong format selected — the file was generated for the wrong target. Re-run with the right format.
- Size too small — the file was downloaded at a size where the encoding can't be reliably read. Bigger is safer.
- Color contrast — if you customized colors, low contrast between foreground and background breaks scannability.
- Damaged in transit — copying the file as a low-resolution image (e.g., a screenshot) destroys detail.
