Resize Image
Set exact pixel dimensions or scale by percentage without stretching.
Resize to the exact size you need
Upload forms that reject anything over 2 MB. Product listings that demand 1200 by 1200 pixels. A profile photo that needs to be square. The fix is a resizer that respects the aspect ratio and tells you what you are getting.

How to resize an image
- Add your image.
- Enter a width or a height. With the ratio locked, the other value follows.
- Choose the fit mode. Contain keeps the whole image. Cover fills the frame and crops the edges.
- Press Resize and download.
Pixels, print and screens
Screen images are measured in pixels. Print images are measured in pixels per inch as well. A photo that looks crisp on a phone can look soft on a poster because the same pixels are spread over a larger area.
- A website hero image is often 1600 pixels wide.
- A social post is usually 1080 by 1080 or 1080 by 1350.
- A printed A4 page at 300 dpi needs about 2480 by 3508 pixels.
- A favicon is 32 by 32 or 512 by 512 for modern devices.
Shrinking versus enlarging
Shrinking is safe. The browser averages neighbouring pixels and the result usually looks clean.
Enlarging cannot create detail. It interpolates, which softens edges. If you need a bigger version of a small photo, start from the original file if you still have it, or use an upscaler designed for the job.
Keep the file small
Resizing down and compressing are different jobs that work well together. Resize first to the dimensions you actually need, then run Compress Image to reduce the file size. Doing it in the other order wastes quality.
If you need to send several images as one document, Image to PDF packages them in a single file, and Merge PDF can join that with other documents.
Frequently asked
Will resizing make the image blurry?
Shrinking an image looks sharp because pixels are removed. Enlarging always softens detail because new pixels have to be invented. No tool can add real detail that was never captured.
Does it keep the aspect ratio?
Yes by default. Lock the ratio and the second dimension updates automatically. Unlock it if you deliberately need a different shape.
What units can I use?
Pixels. For print, 300 pixels per inch is the usual target, so an A4 page at 300 dpi is about 2480 by 3508 pixels.
Are my images uploaded?
No. Resizing happens in your browser on a canvas element.
Can I resize several images at once?
Yes, the same settings apply to the whole batch.
