LocalResizer

LocalResizer is a free browser-based toolkit for practical static image tasks: resizing and compressing JPEG, PNG, and WebP files. The image is processed privately in your browser instead of being sent to a remote processing server. You can set dimensions, work toward common upload-size limits, and download the result without creating an account. Focused pages cover frequently requested targets such as small profile photos, document-upload limits, and social-media image sizes. Related workflows handle cleaning up and resizing an existing signature image, and splitting a static image into a grid of separate tiles. The site explains the tradeoffs between dimensions, file format, transparency, visual quality, and strict file-size targets, so you can choose an appropriate output instead of relying on a hidden preset. It is built for creators, students, site owners, and anyone who needs a quick one-off image adjustment without installing desktop software.
