Free Online Image Resizer
This image resizer changes the width and height of photos and graphics directly in your browser. You can resize by pixels, scale by percentage, keep aspect ratio, convert output format, and batch process multiple images at once.
For the free version, images are processed locally in your browser. Your files do not need to be uploaded to a server before resizing.
Resize by Width, Height, or Percentage
Set exact pixel dimensions when a website, form, email, or social media platform requires a specific image size.
Use percentage resizing when you want a quick 25%, 50%, 75%, or 200% scale change while preserving the original proportions.
Batch Resize Images
Upload multiple images and resize them with the same settings. Each result shows before and after dimensions, file size, output format, and download status.
When more than one image is ready, you can download all resized files as one ZIP archive generated in your browser.
JPG, PNG, and WebP Output Options
Choose original format, JPG, PNG, or WebP. JPG and WebP include a quality slider so you can balance file size and visual quality.
Use PNG or WebP when you need transparency. Use JPG or WebP for photos when smaller file size matters.
Resize vs Crop vs Compress
Resizing changes image dimensions. Cropping removes part of the image. Compressing reduces file size, usually by lowering quality or optimizing encoding.
This tool focuses on resizing, but the output format and quality controls can also reduce file size.
Privacy and Security

Can I resize an image without losing quality?
Downscaling usually keeps good visual quality. Upscaling can reduce sharpness because the browser must create new pixels. For best results, avoid enlarging small images too much.
What is the difference between resize and crop?
Resize changes the image dimensions. Crop removes part of the image to fit a target shape or ratio.

Can animated GIFs be resized?
Browser-only canvas usually captures only one frame of animated GIFs. This MVP warns users that animated GIF resizing is not supported.
Can I change image file size in KB?
You can reduce file size by changing dimensions, output format, and JPG/WebP quality. Exact KB targeting can be added later with iterative compression.
