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 or click in the image to select the file, enter the target width or height (pixels), and other dimensions will be automatically calculated proportionately. You can also switch to percentage mode and enter the zoom ratio directly. 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 pack it into Zip and save in batches.
It is suitable for scenarios such as unifying product map sizes before e-commerce launches, trimming social media covers, and compressing blog map images. Design drafts that require precise pixel control can also be easily output.
The online image zoom tool supports image size adjustment by pixels or percentage, processing in batches, and runs purely on the browser side without the need to upload files.
