Exact pixel dimensions
Prepare an image for a space that needs a specific width or height, without opening a full image editor.

How it works
Set the width and height your image needs, or start with a practical preset. Keep the aspect ratio to preserve its proportions, check the new dimensions, and download the result—all on your device.
- 01
Open your image
Choose a JPG, PNG, or WebP. The original width and height help you decide how much to resize it.
- 02
Set dimensions or a preset
Enter a width or height in pixels, or choose a preset. Keep the aspect ratio enabled to calculate the matching dimension automatically.
- 03
Review and download
Check the resized image and save it to your device. If a form also limits the file size, continue with Compress to Size.
SMALL TOOL. USEFUL DIFFERENCE.
Why use Resize Image?
Keep its proportions
The aspect ratio lock links width and height so your subject stays naturally proportioned as you resize.
A smaller starting point
Reducing dimensions lowers the number of pixels to encode and can help reduce file size. Pair resizing with compression for a tight upload limit.
A FEW GOOD QUESTIONS
Good to know.
Answers before you hit download.
How do I resize an image without stretching it?
Keep the aspect ratio lock enabled and change one dimension. The tool calculates the other dimension from the original proportions. Turning the lock off allows a custom width and height but may stretch or squash the image.
Does making an image larger improve its detail?
No. Enlarging creates more pixels by interpolation, but it cannot recover detail missing from the source. For the clearest result, use a sufficiently large original and resize down when possible.
Is resizing the same as compressing to a file size?
Resizing controls pixel dimensions; compression controls how the image is encoded. A 1000-pixel-wide image does not have one predictable file size. If you need a result below 100 KB, 500 KB, or another limit, use Compress to Size.
