Resize an image online

This free image resizer changes the width, height and file size of your picture in seconds. Enter the exact dimensions you need in pixels, centimetres, millimetres or inches, then choose whether to keep the best quality or shrink the file to a size limit such as 20 KB, 50 KB, 100 KB or 1 MB.

It is useful for photo and signature uploads on exam forms, job applications, ID and passport photos, websites, emails and social media. Everything runs in your browser, so your photo is never uploaded.

How to resize an image

Click Select image or drag and drop your picture.
Enter the new width and height. Keep aspect ratio on to avoid stretching.
Pick JPG or WebP, then choose Set a maximum file size and type your limit in KB or MB.
Click Resize image and download the result.

How to reduce an image to a specific size in KB or MB

Many forms ask for a photo between 20 KB and 200 KB. Choose Set a maximum file size, type the number, and select KB or MB. The tool lowers the image quality step by step until the file fits under your limit, and keeps the best quality that still fits.

Tips for the best result

Use JPG for photos. It gives the smallest files and supports a size limit.
For print sizes in cm or inches, set the DPI to 300.
If the tool cannot reach a small limit, lower the width and height first.
Avoid making a small image much larger, because it will look blurry.

Frequently asked questions

How do I resize an image to 50 KB?

Upload your image, choose Set a maximum file size, enter 50 and select KB, then click Resize image. The tool lowers the image quality until the file is 50 KB or smaller.

Can I resize an image in cm or inches?

Yes. Choose cm, mm or inches as the unit and set the DPI, usually 300 for print. The tool converts the size to pixels for you.

Are my images uploaded to a server?

No. The image is resized inside your browser on your own device. It is never uploaded or stored.

Does resizing reduce image quality?

Making an image smaller in pixels or file size removes some detail. Use High quality for the best result, or set a file size when a form or website has a strict limit.

Which format gives the smallest file?

JPG and WebP give the smallest files for photos and let you set an exact size limit. PNG keeps transparency but cannot be compressed to a target size.

Why can’t the tool reach my target size?

If the width and height are very large, even the lowest quality can stay above a small limit. Reduce the width and height, or raise the size limit, and try again.
