A few key concepts are helpful when resizing images:

• Resolution: Refers to the number of pixels in an image, typically expressed as width x height (e.g., 1920x1080 pixels). Resizing changes this.
• Aspect Ratio: The proportional relationship between an image's width and its height. Maintaining aspect ratio prevents images from looking stretched or squashed.
• Pixelation: Occurs when an image is enlarged too much, causing individual pixels to become visible and the image to appear blocky or blurry. It's generally better to downscale (make smaller) than to significantly upscale (make larger) raster images.
• File Size: Resizing an image, especially making it smaller, will usually reduce its file size (in kilobytes or megabytes), which is beneficial for web performance.

1. Navigate to the Image Resizer: Ensure you are on this page.
2. Upload Your Image: Click the drop area or drag and drop your image file. The image will appear in the preview area.
3. Select Resize Method:
   • Percentage (%): Click the "%" button. Enter the desired percentage (e.g., 50 for half size).
   • Pixels (PX): Click the "PX" button. Enter the maximum dimension for the longest side.
   • Custom (W x H): Click the "W x H" button. Enter your desired width and height. Check/uncheck the "link" icon to maintain/ignore aspect ratio.
4. Observe Preview: The image in the drop area will update to reflect the new dimensions. The dimensions overlay will show original and new sizes.
5. Download: Click the download icon ( ) to save the resized image.
6. Clear (Optional): Click the clear icon ( ) to remove the current image and start over.

• Web Optimization: Reduce image dimensions and file sizes for faster website loading times, improving user experience and SEO.
• Social Media Posts: Resize images to meet the specific dimension requirements for platforms like Instagram, Facebook, Twitter, LinkedIn, etc.
• Email Attachments: Shrink images to reduce file sizes for easier and faster email sharing, avoiding attachment size limits.
• Blog Content: Optimize images for blog posts to ensure they fit layouts and load quickly.
• Online Profiles: Adjust profile pictures to the correct dimensions for various websites and apps.
• Thumbnails: Create smaller preview images for videos, products, or articles.
• Presentations: Resize images to fit slides without distortion or excessive file size.
• Digital Portfolios: Ensure images are optimized for online viewing in portfolios.
• E-commerce: Prepare product images with consistent sizing for online stores.
• Print Preparation (Basic): Adjust dimensions for simple print jobs, though for professional printing, dedicated software is often preferred for color management (CMYK etc.).

• Downscaling (Making Smaller): Generally preserves quality well. Our tool uses algorithms to average pixel data, resulting in a clear smaller image.
• Upscaling (Making Larger): Can lead to loss of sharpness or pixelation, as new pixels must be interpolated (guessed). While our "PX" mode allows upscaling, it's best to start with a source image that is at least as large as your desired output if quality is critical.
• Aspect Ratio: Maintaining the aspect ratio is crucial to avoid distorting your image. Our tool defaults to maintaining it in "Custom WxH" mode and always maintains it in "Percentage" and "Pixels" modes.
• Original Image Quality: The quality of the resized image heavily depends on the quality of the original. A low-quality original will result in a low-quality resized image.
• File Format: Resizing a lossy format like JPG multiple times can degrade quality. If you need to perform many edits, consider working with a lossless format if possible, or do all resizing in one step.

What image formats can I resize?

You can resize JPG, JPEG, PNG, WEBP, GIF, BMP, and TIFF images.

Is there a limit to the image file size I can upload?

While there's no strict limit, very large files (e.g., over 20-30MB) might be slow to process in the browser. For best performance, try to use reasonably sized source images.

Will resizing an image reduce its quality?

Making an image smaller (downscaling) generally maintains quality well. Making an image significantly larger (upscaling) can lead to some loss of sharpness or pixelation. The tool aims to provide the best possible quality for the chosen dimensions.

How do I maintain the aspect ratio?

The "Percentage" and "Pixels" modes always maintain aspect ratio. In "Custom W x H" mode, the aspect ratio is maintained by default (link icon is active). You can click the link icon to "unlink" and set width and height independently, which may distort the image.

Are my images uploaded to a server?

No. All image processing and resizing happen directly in your web browser. Your images never leave your computer, ensuring your privacy.

Can I resize multiple images at once (batch processing)?

Currently, this tool is designed for resizing one image at a time to provide an interactive preview. For batch processing, you might need to use a different tool or desktop software.

Why does the "New" dimension in the overlay sometimes not exactly match my input in "Pixels" mode?

In "Pixels" (Max Dimension) mode, the tool sets the LONGEST side of your image to your input value, and then calculates the OTHER side to maintain the aspect ratio. So, if you have a 1000x500 image and input 800px, the new dimensions will be 800x400px. If you input 400px, the new dimensions will be 400x200px. The overlay shows the actual resulting width and height.

Can I use this tool on my mobile device?

Yes, the Image Resizer is designed to be responsive and should work on most modern mobile browsers.

We prioritize your privacy and data security:

• Client-Side Processing: All resizing operations are performed directly in your web browser. Your image files are not uploaded to or stored on any server.
• No Data Collection: We do not collect or store any personal data or the images you process.
• Secure Connection: Our website uses HTTPS to ensure a secure connection between your browser and our site.
• Instant Deletion (Implicit): Since files are processed in-browser, they are effectively gone from the tool's context once you clear the image or close the page.

You can use our Image Resizer with confidence, knowing your images remain private.

• Start with a Good Quality Original: The better the quality of your source image, the better the resized result will be.
• Avoid Excessive Upscaling: If possible, avoid making images much larger than their original size to prevent significant quality loss.
• Know Your Target Dimensions: If resizing for a specific platform (like a social media banner), find out the recommended dimensions beforehand.
• Check Aspect Ratio: For most purposes, you'll want to maintain the original aspect ratio to prevent your image from looking stretched or squashed.
• Preview Before Downloading: Use the live preview to ensure the resized image looks as expected.
• Consider the Purpose: For web use, smaller dimensions and file sizes are generally better. For print, higher resolution might be needed (though this tool is primarily for screen-based resizing).
• Save a Copy: It's often a good idea to work on a copy of your original image, so you always have the original file intact.
