Placeholder Image Generator

Generate a labelled placeholder PNG. No source photo needed.

Placeholder Image Generator is its own job in the catalog (developer): Generate a labelled placeholder PNG. No source photo needed. It is not a copy of the resizer or converter with a new title — the operation is “placeholder”.

Controls on this page: Width, Height, Background, Text. Output defaults to the format shown.

Placeholder Image Generator runs in this browser with Canvas. The file is not uploaded to imagecropx. Close the tab and the copy in memory is gone.

What this is not

There is no account and no file locker. If a format cannot be written, the tool says so.

Questions about this tool

No. Processing is in this browser.

Can I use this on a phone?

Does Placeholder Image Generator upload the file?

No. This tool runs in the tab. See Privacy for decoder notes (HEIC, PDF.js worker).

What is the file size cap?

About 25 MB per file. Very large pixel counts are rejected so the tab stays responsive.
