About Custom Dimension Resizer

Custom Dimension Resizer is here for changing image dimensions to a target size: full control: width, height, fit or fill. It takes JPG, JPEG, PNG and 9 more and produces JPG, JPEG, PNG, WEBP. Files up to 100 MB each, 50 at a time, and the work happens on your own machine rather than on a server.

The slow route to changing image dimensions to a target size is installing something, making an account and uploading the file; this is the fast route.

How to use Custom Dimension Resizer in 3 steps

  1. Add one image or a batch of up to 50; mixed formats are accepted.
  2. Set Width (px) and Height (px), with Lock aspect ratio deciding which one follows.
  3. Press Resize image and download the result in whichever of JPG, JPEG, PNG, WEBP suits you.

Custom Dimension Resizer: questions

Is this free, or free until it asks for a card?
Free, with no upsell behind it: no account to create and no file-count quota that appears halfway through a job.
Which file types does Custom Dimension Resizer accept?
The drop area takes JPG, JPEG, PNG and 9 more. Files are read from your device in the browser, so the format has to be one a browser can decode — that is why the accepted list on this page is finite and honest rather than "everything".
What do I get back from Custom Dimension Resizer?
The result is JPG, JPEG, PNG, WEBP, offered as a download the moment the work finishes. Multiple results come back together rather than as fifty separate save dialogs.
How big a file can I use?
Up to 100 MB per file and 50 files per batch. There is no server queue behind that limit; the practical ceiling is your browser's memory, so split unusually large documents into two runs.
