How to resize a JPG image online
Resizing a JPG image changes the image's pixel dimensions, such as reducing a large photograph to 1200×800 pixels or creating a smaller image for a website, application, form, profile, or document.
With Lets Resize It, you can resize JPG and JPEG images directly in your browser. Upload your image, enter the target dimensions, choose whether to preserve the aspect ratio, and download the resulting JPG.
What is JPG resizing?
JPG resizing changes the width and height of an image in pixels. For example, an original image measuring 3000×2000 pixels can be resized to 1500×1000 pixels while maintaining the same 3:2 aspect ratio.
Resizing is different from simply cropping an image. A resize changes the dimensions of the complete image, while cropping removes part of the image.
Can I resize a JPG to a specific size?
Yes. You can enter the exact width and height required for your image. If you know the dimensions required by a website or application, enter those pixel values in the resize tool above.
How do I resize JPG without losing quality?
Image resizing can affect visual quality, particularly when a very large image is reduced substantially or a small image is enlarged. Using an appropriate output size and JPG quality setting can help maintain a good balance between appearance and file size.
When reducing an image, avoiding unnecessarily aggressive compression can help preserve details. For web use, however, a smaller JPG can often provide faster loading while still looking good.
Resize JPG while keeping the aspect ratio
The aspect ratio describes the relationship between an image's width and height. Locking the aspect ratio helps prevent the image from becoming stretched or squashed when you change one dimension.
If you need a specific square output such as 200×200 or 300×300, use one of our fixed-dimension image resizing tools.

JPG resizing vs JPG compression
Resizing and compression solve different problems. Resizing changes the pixel dimensions of an image. Compression reduces the amount of data required to store the image and can reduce its file size.
If your requirement is specifically a maximum file size such as 50 KB, 100 KB, 200 KB, or 500 KB, use one of our file-size-focused tools instead.
