  2. Set the options you want, then run the tool.
  3. Preview the result and download it. The file never leaves your computer.

Frequently asked questions

Are there any usage caps on the Image Dimension Checker?
There is no cost and no cap. The Image Dimension Checker is not a demo of a paid product, so nothing is held back or watermarked.
Is the Image Dimension Checker safe to use with private information?
No. The Image Dimension Checker runs entirely in your browser using JavaScript. Because the work happens locally, the utility also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What is the Image Dimension Checker used for?
Typical uses: checking whether an image is big enough to print. Confirming an asset matches a required size. Comparing dimensions across a batch. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Will a big file be rejected?
There is no limit set by us, because your file is never uploaded — the only ceiling is the memory your own browser will give the tab. Very large files simply take longer to process, and a phone will give up sooner than a desktop.
