These tools are built and maintained by one person, and messages come straight to me rather than to a support queue.

Wrong results are the priority

If a tool gives you an answer you believe is incorrect, please say so — that matters more to me than anything else here. Accuracy is the only thing a tool like this is for, and a number that is quietly wrong is worse than no tool at all.

It helps enormously if you can include:

• Which tool, and what you expected to see instead
• The kind of file involved — a universal APK, an App Bundle, an SVG icon — and roughly its size or dimensions
• Your browser and operating system

Please do not attach the file itself. I have deliberately built this site so that your builds never reach me, and I would rather keep it that way. A description is almost always enough to reproduce the problem.

Play's rules have changed

Google updates its size limits, asset requirements and listing rules regularly, and this site can fall behind. If you find something here that no longer matches the official documentation, tell me and include a link to the current source. Those corrections get made quickly.

Feature requests

If there is a repetitive job in your Android workflow that a small browser tool could remove, I would like to hear about it. The three tools here all began as annoyances in my own projects. The useful ones are usually specific and dull, which is exactly the point.

What I cannot help with

I cannot review your app, help with Play Console policy appeals, debug your project's code, or advise on why a submission was rejected. For anything involving your Play account or a policy decision, Google Play support is the only place that can actually act.

Why there is no contact form

A form would need a server to receive it. This entire site is static, with nothing running behind it — that is what allows me to promise your files never leave your browser. Adding a form would mean adding a backend, so email it is.

Replies

I read everything. I usually reply within a few days, though I am one developer in one time zone, so it can occasionally take longer. Reports of incorrect results get answered first.
