Why use this tool?
- A 4000-pixel photo used as a 400-pixel avatar wastes bandwidth on every single page load.
- Upload forms frequently specify exact dimensions and reject anything else.
- Locking the aspect ratio is what stops a resized photo looking stretched.
How to use Image Resizer
- Add the image.
- Enter a width or height in pixels, or a percentage of the original.
- Leave the ratio locked unless you deliberately want to distort it.
- Choose the output format and download.
Features
- Resize by pixels or by percentage

Frequently asked questions
Can I make a small image bigger without it going blurry?
Not with a plain resize — enlarging invents pixels that were never captured. The Image Upscaler does a better job of it with stepped resampling.
Will resizing change the file size?
Yes, substantially. Halving both dimensions removes about three quarters of the pixels.
Can I try this Pro tool without an account?
Yes. Resize your image and preview it at up to 640 pixels. Pro saves the exact full-size result. Your own input is processed locally in your browser.
Will upgrading keep my work?
Checkout and login open in a separate tab. Keep the workspace open to retain inputs, settings and previews. Files stay in that tab only; keep the originals in case you close or reload it. Export access is checked with the server after payment.
