Image Upload Size Limiter

Set your own maximum width and height for uploaded images instead of WordPress's fixed 2560 px limit.

Version 1.0Updated Mar 2025Downloads 0

What it does 01

WordPress caps big uploads at 2560 × 2560 px before scaling, and that limit is hard-coded — there's no setting for it. Most of my uploads never need more than 1920 px, so this plugin lets you choose your own.

  • Set a custom maximum width and maximum height in pixels.
  • Adds a simple Media → Image Size Limits settings page.
  • Super light — just 106 lines of code.

Setup 02 · about 1 minute

  1. Install it. In WordPress go to Plugins → Add New → Upload Plugin, choose the .zip you downloaded and click Install Now.
  2. Activate it from the same screen (or later from Plugins).
  3. Set your limits. Go to Media → Image Size Limits, enter a Maximum Width and Maximum Height in px (both start at 2560) and click Save Changes.
  4. Upload as usual. Images you upload from now on are kept within your limits.

FAQ 03

What are the defaults?

Both fields start at WordPress's own 2560 px. Lower them to whatever your site actually needs — most of my uploads never need more than 1920 px.

Why can't I just change this in WordPress?

The 2560 px limit is hard-coded, so there's no setting for it. This plugin adds one.

Which WordPress versions does it support?

It's listed for any WordPress version — the whole plugin is 106 lines of code.

Is it really free?

Yes — GPL-2.0, free forever, no upsells inside the plugin.
