Image Resizer

This free Image Resizer lets you change the width and height of any picture quickly, without installing an app or signing up. Resizing is useful in everyday situations: a website form may reject a photo that is too large, an online shop may need product images at an exact size, a school or job application may ask for a passport style picture with fixed pixels, or you may simply want a smaller file that uploads faster and takes less space on your phone.
The tool works completely inside your browser. When you pick an image, it is read on your own device, resized on a hidden canvas, and offered back to you as a download. Nothing is uploaded to a server, so your personal photos stay private. You can keep the original shape of the picture by leaving the aspect ratio option ticked, which prevents faces and objects from looking stretched or squeezed. You can also choose the output format: JPEG is best for most photos and gives a small file, PNG keeps sharp edges and transparency, and WebP often gives the smallest size with good quality for websites.
How to use
- Click the file box and choose an image from your phone, tablet, or computer.
- Note the original dimensions shown, then type the new width you want in pixels.
- If keep aspect ratio is ticked, the height fills in automatically to match.
- Or tap a quick size button, such as 50 percent, to halve both dimensions instantly.
- Choose JPEG, PNG, or WebP, click Resize Image, check the preview, then download.
Frequently asked questions
Will resizing reduce the quality of my image?
Making an image smaller usually keeps it looking clear, especially on screens. Making a small image much bigger can look blurry, because the tool cannot invent detail that was never in the original picture.
What does keep aspect ratio mean?
It keeps the same relationship between width and height as the original. When it is on, changing one side adjusts the other automatically, so your image does not get distorted.
Which format should I choose?
Choose JPEG for photos and sharing, PNG if you need transparency or very crisp graphics, and WebP if you want the smallest file for a website and your browser supports it.
Are my images uploaded or stored?
No. All processing is local in your browser. Your image never leaves your device, and nothing is saved by this tool after you close the page.
