What is Resize Image?
Resize Image lets you change the width and height of any photo or graphic to exact pixel dimensions — entirely in your browser. Enter custom dimensions or choose from common presets for social media, profile photos, or standard web sizes. Lock the aspect ratio to prevent distortion.
Preview the result before downloading, and save the resized image as JPG or PNG. No upload, no account, no waiting. Because processing happens in your browser, images are never transmitted to any server.
Common Use Cases
- Creating thumbnails for web pages and blog posts
- Resizing profile photos to meet platform pixel requirements
- Preparing banner and cover images for social media
- Scaling product photos to e-commerce listing dimensions
- Resizing images to pass form upload size requirements
How to Use Resize Image
- Upload a JPG, PNG, or WebP image from your device.
- Enter the target width and height in pixels, or select a preset size.
- Lock the aspect ratio if needed, then download the resized image.

FAQ
Is my image uploaded to a server?
No. Resizing runs entirely in your browser using the Canvas API. Your image never leaves your device.
Which image formats are supported?
You can upload JPG, PNG, and WebP images. The resized output can be downloaded as JPG or PNG.
Can I maintain the original aspect ratio?
Yes. Enable the aspect ratio lock — changing either width or height will automatically update the other dimension proportionally to avoid stretching.
Can I make an image larger (upscale)?
Yes, but upscaling beyond the original resolution will reduce sharpness since new pixels are interpolated. The maximum supported dimension is 8000 px on either side.
What size presets are available?
The tool includes presets for 1:1 square, 800×600, 1280×720, and 1920×1080. You can also type in any custom dimensions you need.
What is the difference between resize and compress?
Resize changes the pixel dimensions of the image — making it physically smaller or larger. Compress reduces the file size by lowering quality without necessarily changing dimensions. Both affect file size, but resize changes how large the image appears on screen while compress affects visual sharpness at the same display size.
