A portal rejected your file and its message was three words long. Before you fix the file, read it properly: exact bytes, real format, dimensions, pages or duration, and how it stands against the doors portals set. The file is measured here in your browser and never uploaded.

Pick a file to read its spec.
The doors appear once a file is read.
The page reads the file's first bytes to name its real format (a file renamed to .jpg that is really a PNG is called out), counts the bytes exactly, and opens the file just far enough to read its dimensions, page count or duration. Nothing is converted and nothing is kept: close the page and it is gone.
This page reports the file you have; it does not change it, and it cannot know a specific portal's private rules beyond the limits they print. When a file is over a door, the benches next door do the shrinking: Compress PDF and Compress image take an exact target and work to land under it.
Because portals count differently and file managers round. This page prints the exact byte count, the size in both KB conventions, what the file actually is (read from its first bytes, not its name), and for pictures, PDFs and recordings the dimensions, pages or duration a portal will see. Then it lines the file up against the doors portals actually set.
Yes. Some portals reject files under a minimum as firmly as over a maximum (a scan that is too light looks blank to their checks). The exact byte count on this page is the number to compare against their wording.
Both, in different units. Some systems count 1 KB as 1,000 bytes, others as 1,024. This page prints the exact bytes and the 1,000-byte KB figure side by side so you can match whichever the portal uses.
Nowhere. It is read into this page and measured in your browser. Watch the network panel while it works if you want to check.
