About This Tool
The Image Resizer changes the pixel dimensions of JPG, PNG, WebP, and other browser-readable images. You can enter an exact width and height, preserve the original aspect ratio, or resize the image by a percentage. Side-by-side previews and dimension summaries make the result easy to check before downloading.
ToolPool runs this utility in your browser, so your input stays on your device and is not uploaded to our server.

Workflow Tips
Image Resizer is designed for quick browser work, but it is still worth reviewing the result before you use it in a live project, client document, public page, or production workflow. Keep an original copy of important source material, compare the output with what you expected, and repeat the task with slightly different settings when quality, formatting, or accuracy matters.
For larger workflows, pair this page with Image Compressor, Image Cropper, WebP Converter, Image Converter. Moving between related utilities can save time when you need to clean source data, prepare web assets, create supporting IDs, check calculations, or package output for another system. Internal links also make it easier to stay in one private workspace instead of jumping between several single-purpose sites.
The local processing model helps protect sensitive content because ToolPool does not need to receive your files, text, or form values to complete the task. Good privacy habits still matter after the result leaves the page: avoid pasting unnecessary secrets, check downloaded files before sharing them, and clear the workspace when you are finished on a shared computer.
