Resize Image in Pixels or KB
Resize an image by exact pixel width and height, and compress it to a target file size in KB. Lock the aspect ratio so nothing stretches, then resize and download. Runs in your browser, no upload, no account, no limit.
How to Resize an Image
Upload Your Image
Drag and drop your image or click to choose one. Its current pixel size fills in automatically.
Set the New Size
Type the width and height in pixels. Keep Lock Aspect Ratio on so the shape stays, and set a target KB if a form needs it.
Resize and Download
Click Resize and Download to save the image at the new size, compressed to your target file size.
Resize an Image to Exact Pixels and File Size
Designers, marketers, and developers all need precise pixel dimensions for hero images, banners, avatars, and thumbnails. Type the target width and height, and the resizer outputs an image at exactly that size, with no rounding errors. Lock the aspect ratio and one side follows the other, so faces and logos never stretch.
When a form or upload caps the file size, set the target in KB. The default is your uploaded file size, so lower it to compress further. The tool steps the JPEG quality down, and shrinks the pixels only if needed, until the file fits, so you can resize an image in KB without guessing the quality.
Everything runs in your browser, whether you are here in India or anywhere else, so the image never leaves your device. Need many files at once? The bulk image resizer handles a whole folder, while this single-image flow stays the fastest path for one-off assets. To hit only a KB limit, use the reduce image size tool.

Frequently Asked Questions
Common questions about resizing images online.
How do I resize an image to exact pixels?
Upload your image, type the target width and height in pixels, and click Resize and Download. The image is resized to those exact dimensions. It is free and runs in your browser.
How do I keep the image from stretching?
Keep Lock Aspect Ratio turned on. When it is on, changing the width updates the height automatically, so the picture keeps its original shape and nothing looks squashed.
Can I resize an image to a specific KB size?
Yes. The target size field defaults to your uploaded file size, and you can lower it. The tool tunes the JPEG quality, and shrinks the pixels only if needed, to match the KB you set.
What image formats can I resize?
You can upload JPG, PNG, WebP, and GIF images. Whatever you upload, the resized result downloads as a JPG, which keeps the file small for the web and uploads.
Does resizing lower the image quality?
Making an image smaller keeps it sharp. Making it much larger than the original can look soft, since there are no extra pixels to add. For best results, resize down or keep close to the original size.
Is my image safe when I resize it?
Yes. The whole process runs inside your browser, so the image never leaves your device and is never uploaded to a server. Nothing is stored or shared.
