Contact

FileGizmo has no account system and no support form that stores your message. Bug reports, tool requests and product feedback all arrive the same way, by email to the address below.

Report a bug or request a tool

Email support@promethir.com with the tool name in the subject line.

A useful report includes the tool name, browser and operating system, the steps you took, what you expected, and what happened instead. If possible, use a harmless sample file that contains no private information.

Never attach a sensitive originalA bug report does not need your real file, and sending one hands us a copy of something the tool itself was careful never to receive. Do not attach personal documents, API keys, identity records, private images, or confidential business data. Describe the structure of the file, or build a safe reproduction that fails the same way.

Making a safe sample file

Most problems can be shown with a file made for the purpose. For a PDF, save one page of a public document, such as a product manual, through your browser's Print to PDF, then check that the tool still fails on it. For a spreadsheet or CSV, copy the header row and two or three rows, and replace names, numbers and addresses with made-up ones. For an image, a photo of a plain wall or a screenshot of this page is usually enough.

If the problem only happens with one particular file, describe it instead of sending it: its size, how many pages or rows it has, which program made it, and whether it is password-protected. That is often enough to reproduce the failure.

When a result looks wrong

Include the line the tool showed under the result, such as the page count or the number of rows, and say what you expected it to be. Copy any error message word for word. A screenshot of the result screen helps, as long as it shows no private content.

Security reports

If a problem could expose another person’s information or create an active security risk, do not publish exploit details or real files. Send a short email asking for a private reporting channel, without the sensitive details in it. The maintainer can then arrange an appropriate private handoff.

What to expect

FileGizmo is independently maintained and does not promise a fixed response time. Clear, reproducible failures receive priority over broad feature requests. A request may be declined when it would require uploading files, weaken the privacy model, or add disproportionate complexity.

Before contacting us

  • Try the file again in a current version of Chrome, Edge, Firefox, or Safari.
  • Confirm the file opens normally in another trusted application.
  • Read the tool’s limits and error message; encrypted or malformed files may need preparation first.
  • Check the changelog for a recent fix.
