About this tool
Image Resizer is a free online image tool. Resize images online with quality control. Edit and create images right in your browser. It runs entirely in your browser — no download or sign-up needed.
After opening the page, drag in the image or click to select a file, enter the target width or height (pixels), and the other dimension will be automatically proportional calculated. You can also switch to percentage mode and directly enter the zoom ratio. Support adding multiple pictures in batches and outputting them at one time.
All processing is done locally in the browser, and pictures will not be uploaded to any server. The bottom layer uses the Canvas API for resampling, and the output format can be PNG, JPEG or WebP. After processing, click directly to download, or package it into ZIP and save in batches.
It is suitable for scenarios such as unifying product map size before e-commerce launches, trimming social media covers, and compressing blog map images. It is also convenient to export design drafts that require precise pixel control.
Online image zooming tool supports adjusting image size by pixels or percentages, processing in batches, and running purely on the browser side without uploading files.
