Most built-in tools only strip part of it. Here's what each method actually removes, how to check the result, and the side effect that turns photos sideways.
Read guide →Why Your Photos Turn Sideways (And How to Fix It Properly)
The photo isn't rotated — a flag in its metadata is. That's why it looks right on your phone and wrong everywhere else, and why rotating it sometimes makes it worse.

One question decides it: is the image a photograph or a graphic? Plus the myths about PNG quality and printing that cause most of the confusion.
Read guide →Image Upload Failed With No Error? Work Through This

Screenshots are full of text and hard edges — exactly what JPEG compresses worst. Why the format is usually the problem, and what to change before you send.
Read guide →DPI Explained — And Why It Doesn't Mean What You Think

Read guide →PNG Not Transparent? Here's How to Diagnose It
Sometimes the file has no alpha channel. Sometimes it does and the app is drawing it over white. How to tell which problem you have before you try to fix it.
