When you need a specific width and height that no preset covers, this tool puts the numbers in your hands. Type the pixel dimensions you want and it redraws your image to match — with an option to lock the aspect ratio so nothing looks stretched.
The resize is done entirely in your browser, keeping the process fast and your files private.
How to use Resize Image by Pixels
Using Resize Image by Pixels takes only a few seconds and just four simple steps — no sign-up, no software, and nothing to learn:
- Upload your image: Add the photo or graphic you want to resize.
- Enter width and height: Type your target pixels. Keep 'lock ratio' on to scale proportionally.
- Resize: Run the tool to redraw the image at your chosen dimensions.
- Download: Save the resized file for whatever you need it for.
What you can do with Resize Image by Pixels
Resize Image by Pixels is built to do one job well, and gives you everything you need to get it exactly right:
Fully custom dimensions. Any width and height you type — no presets standing in your way.
Aspect-ratio lock. Keep proportions intact, or unlock to stretch to an exact size.
Private, in-browser resizing. Images are processed on your device and never uploaded.
Free with no limits. Resize as many images to as many sizes as you want.
Total control over dimensions
Presets are convenient until your requirement is something unusual. This tool covers every other case: enter any pixel size, decide whether to preserve the ratio, and get an exact result without opening heavy editing software.
Whether you need it once or every day, Resize Image by Pixels keeps the process quick and predictable. Because it focuses on a single task, there are no crowded menus to wade through — you open the page, set what you need, and get your result. That simplicity is exactly why a dedicated image tool beats a heavyweight editor for a job like this.
Everything runs in your browser
Unlike most online tools, Resize Image by Pixels never uploads your image to a server. The moment you choose a file, it is processed right here in your web browser using your own device's power. Nothing is sent over the internet, nothing is stored, and nothing is shared with anyone.
That gives you two real advantages. First, it is private: sensitive documents, ID photos and personal files never leave your computer or phone. Second, it is fast — there is no slow upload or download round-trip, so even large files are handled almost instantly. And it is completely free, with no watermark added to your result and no account required.
Tips for the best results
- Start from the highest-quality original you have — the better the input, the better the result from Resize Image by Pixels.
- Check the exact requirement — size, dimensions, or format — before you begin, so you only need to do it once.
- Fully custom dimensions: Any width and height you type — no presets standing in your way.
- Aspect-ratio lock: Keep proportions intact, or unlock to stretch to an exact size.
- Everything is repeatable — if the result isn't quite right, just adjust the settings and run it again. Nothing is uploaded, so you can try as many times as you like.
Frequently asked questions
What does 'lock aspect ratio' do?
With it on, changing the width updates the height automatically (and vice versa) so the image keeps its proportions and never looks squished.
Can I make an image larger?
Yes, but enlarging beyond the original size can look soft because the tool has to add pixels that were not there.
Which formats are supported?
JPG, PNG, and WebP. The output keeps your original format, including PNG transparency.
Is Resize Image by Pixels free to use?
Yes — Resize Image by Pixels is completely free. There is no account to create, no subscription, and no watermark added to your result. Use it as many times as you need.
Do I need to install anything?
No. Resize Image by Pixels runs entirely in your web browser on any modern device — Windows, Mac, Android or iPhone. There is nothing to download or install.
