Frequently asked questions

Is there a limit on how often I can use the Image Resizer?
It is free, with no account, no trial and no daily cap. Every image tool on inputtesthub.com works the same way: open the page and use it.
Does anything I enter leave my computer?
No. The Image Resizer runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
Who is the Image Resizer for?
The most common reasons people reach for it: fitting an image to a platform's required dimensions. Shrinking a camera photo for the web. Resizing a batch to a consistent width. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Is there a file size limit?
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.
