Run the resize
The tool redraws each image in your browser and shows the new dimensions and output file size.
Download single files or ZIP
Save one result at a time, or package a resized batch into one ZIP file.
Why Use This Free Online Image Resizer?
Use it when you need a quick, private way to change image dimensions for uploads, websites, forms, product photos, thumbnails, or content batches.

Set a specific width and height in pixels when an upload form or layout requires fixed dimensions.
Percentage scaling
Scale images up or down from 1% to 400% while keeping the original proportions.
Batch resize with ZIP
Resize multiple images with the same settings, then download individual files or one ZIP package.
Browser-side processing
For normal use, images are decoded and resized locally in your browser instead of being uploaded for server-side processing.
Output dimensions visible
Check each result's original dimensions, output dimensions, input size, and output file size before saving.
Works with common image files
JPG files export as JPG, WebP files export as WebP, and other supported browser image inputs are exported as PNG.
Image Resizer FAQ
Answers about exact pixels, percentage resize, batch downloads, privacy, formats, and KB limits.
How do I resize an image online?
Upload your image, choose Exact pixels or Percentage, then click Resize Images. The tool shows the new output dimensions and file size before you download.
How do I resize an image to exact width and height?
Upload your image, choose Exact pixels, enter the target width and height, then click Resize Images. The result shows the new output dimensions before you download.
Can I resize multiple images at once?
Yes. Add several images, choose one pixel or percentage setting, resize the batch, then download each result separately or save everything as one ZIP package.
Can I resize an image without uploading it?
No. This image resizer uses browser-side image decoding and canvas resizing, so selected files are processed locally on the page during normal use.
Can I resize JPG, PNG, and WebP images?
Yes. You can select common browser-supported image files. JPG input exports as JPG, WebP input exports as WebP, and other supported image inputs export as PNG.
Can this resize an image to 100KB or 200KB?
Not directly. This tool resizes image width and height, not exact file weight. For targets such as 100KB, 200KB, or 500KB, resize dimensions first if needed, then use Image Compress to reduce file size.
Will resizing change image quality?
Reducing dimensions usually keeps images clear for smaller display sizes. Enlarging an image can make it look softer because the browser has to create extra pixels from the original.
How do I keep the aspect ratio when resizing?
Use Percentage mode when you want to keep the original aspect ratio automatically. Exact pixels mode uses the width and height you enter, so choosing a different aspect ratio can stretch or squeeze the image.
Does resizing reduce file size in KB?
Often, especially when you reduce pixel dimensions, but this page does not target an exact KB or MB value. It changes dimensions first. Use Image Compress when the upload limit is about file size.
Should I use pixels or percentage?
Use pixels when a site gives you a required width and height. Use percentage when you want proportional scaling, such as making every image 50% smaller or 200% larger.
Will exact width and height stretch my image?
It can. Exact pixels mode uses the width and height you enter, so choosing dimensions with a different aspect ratio can stretch or squeeze the image. Use percentage mode when you want to preserve the original proportions automatically.
Why did my resized image export as PNG?
When the input is not JPG or WebP, this tool exports the resized result as PNG. This keeps the workflow predictable for browser-supported image types that do not map directly to JPG or WebP output.
Can I download all resized images as a ZIP?
Yes. After resizing a batch, choose ZIP package from the batch download control. If there is only one resized file, the tool downloads that single file.
What should I do if the resized image is still too large?
If the dimensions are correct but the file is still over a KB or MB limit, send the resized file through Image Compress. If the upload still complains about width or height, return here and resize to smaller pixel dimensions.
Can I enlarge an image above 100%?
Yes. Percentage mode supports scaling up to 400%. Enlarging can make photos or screenshots look softer because the browser has to create extra pixels from the original image.
