About this tool
Designed for the moment you need a document changed quickly and privately. Resize images by pixel or percentage with aspect-ratio lock. Everything runs locally in your browser. Processing runs locally in your browser's memory — the document is never transmitted, and closing the tab clears it completely. The workflow is deliberately short: load the file, choose the options on the page, run the operation, and save the result. Every choice is applied before the file is written, so re-running with different settings takes seconds. Output covers JPG, JPEG, PNG, WEBP and more; it pairs well with the related tools linked beside this page when one step is not the whole job. Key facts — Processing: runs entirely in your browser, client-side; Access: free with no account required; Privacy: the file never leaves the device.
How to use
Upload an image

FAQ
Will my file be uploaded?
No. Everything runs locally in your browser — your file is never uploaded.
What formats are supported?
Supports common image formats including JPG, JPEG, PNG, WEBP, and AVIF. The resized image is exported in its original format.
Will it lose image quality?
Resizing uses in-browser Canvas resampling; entering width or height auto-scales the other dimension to prevent distortion, exporting in the original format with default quality encoding. If you need a specific target file size or side-by-side quality comparison, please use the dedicated Image Compress tool.
Can I process multiple files in bulk?
This tool is designed for individual image resizing. For resizing multiple images at once, please use the Batch Image Processing tool.
Is the processed file still editable?
The result is a new resized image file; the original image is left unchanged.
