Image Resizer
Resize an image to a target width, with the aspect ratio preserved by default — entirely in your browser, the image is never uploaded anywhere.
Resize an image to a target width, with the aspect ratio preserved by default. Choose an image below — it’s processed entirely in your browser and never uploaded anywhere.
How it works
Your image is decoded and redrawn using the browser’s built-in Canvas API — the same technology behind most in-browser image editors. The file never leaves your device: there is no upload, no server round trip. Choose a target width (or keep the original), then click Resize.
FAQs
Is my image uploaded anywhere?
No. The entire resize happens in your browser using the Canvas API. Your image file is never sent to a server.
What image formats are supported?
Any format your browser can display natively — JPG, PNG, WebP, GIF, and more. The resized image is saved in the same format as your original.
Is there a file size limit?
Yes, 25 MB — large enough for virtually any photo, while keeping the browser’s memory use reasonable during processing.
