A named platform preset works when the destination is Instagram or a LinkedIn banner, but sometimes the actual requirement is a specific pixel width and height typed in directly, decided by a form's upload rules or a design spec rather than any named platform, and applied across a whole batch of files at once rather than one image at a time. This tool resizes images to exact pixel dimensions with an aspect ratio lock and batch support, built around typed-in target dimensions applied to many files together rather than a single platform preset. Useful for resizing a whole batch of product photos to one exact required pixel size at once, locking the aspect ratio so a resize stays proportional instead of distorting, or hitting a precise width and height dictated by an upload form's rules rather than any named social platform.
Resize images to exact pixel dimensions with aspect ratio lock and batch support. The Image Size Resizer is one of 900+ free developer tools on Toolblip - all open to use without a signup.
