Why resize to exact pixels?
Different places need different image dimensions: a blog post might want 1200px-wide images, a video thumbnail 1920×1080, and a profile picture 300×300. This free tool resizes your photo to any exact width and height, with the aspect ratio locked by default so nothing gets stretched.
Enter the two numbers you need — or change just one and let the lock fill in the other — and the tool redraws your image with high-quality smoothing. Shrinking keeps photos sharp, and the download is ready instantly.
All processing happens locally in your browser, so your photo is never uploaded. Try Resize in Pixels or Resize by Percentage.

Frequently Asked Questions
What is the difference between pixels and KB?
Pixels measure the image's width and height, like 1920×1080. KB measures the file size on disk. Smaller pixel dimensions usually mean a smaller file, but compression also matters — which is why resize-to-KB tools adjust both.
What does a photo resizer do?
It changes the width and height of a photo in pixels so it fits a specific use — like 800×600 for a blog or 1920×1080 for a video thumbnail. This tool also lets you control quality and format.
What size should I resize my photo to?
For email, 800–1200px wide is plenty. For websites and social media, 1200–1920px wide covers most layouts. For printing at 300 DPI, use the print size in inches × 300 to get pixels.
Will resizing make my photo blurry?
Shrinking a photo keeps it sharp. Enlarging it adds blur, so try to keep the largest source you have and resize down to your target.
Can I keep the aspect ratio?
Yes — the aspect ratio lock is on by default, so changing one dimension automatically adjusts the other and your photo is never stretched.
