Free Online Image Resizer - Make Pictures Smaller

To reduce image size to specific dimensions, select your image from your phone or computer and choose "Max Size (px)" under Step 2. Enter your desired values in the Width and Height input fields. Keep the aspect ratio locked to scale proportionally without distortion, or unlock it to set dimensions freely. If you need to fit specific dimensions without stretching by cropping the edges, use our Image Cropper. To reduce image size by shrinking the file size while maintaining the original dimensions, use our Image Compressor.

To change photo size proportionally by percentage, select the "Scale (%)" option under Step 2. Use the slider or enter a number in the input box to scale the image up or down (for example, set it to 50% to reduce the width and height by half). This method ensures that the original aspect ratio is perfectly maintained.

To resize multiple images at once, select multiple files together from your phone or computer. Under Step 2, configure your resizing settings (either by maximum width/height or by scale percentage) to apply them across all selected images. After processing, click "Confirm Resize" and download the resized images individually or as a single ZIP archive.

To customize the file type and quality of your resized image, locate the output settings under Step 2. Whether you need to resize jpg photos or resize png graphics, you can choose from supported formats like JPG, WebP, AVIF, or PNG. For lossy formats (JPG, WebP, AVIF), adjust the quality slider to find the optimal balance between visual quality and file size.

To check the quality and details before saving, use the preview area below the configuration options. In single-image mode, click the toggle button to switch between the original and resized previews, or hover over the image to activate the magnifier tool on desktop to compare fine details.

Enable Fast Mode under Step 2 to speed up the resizing process, which is particularly helpful when processing a large batch of images or when time is limited. Fast Mode utilizes your browser's native encoding capabilities for rapid turnaround, whereas turning it off uses advanced software encoders to achieve the smallest possible file sizes.

Disable Fast Mode when your images require maximum visual clarity and compression efficiency, such as product photography, professional portfolio displays, and detailed marketing assets. This runs advanced encoding algorithms to optimize file size while preserving fine visual details.

To resize images on your smartphone, open the tool in any modern mobile browser (such as Safari or Chrome). Select your photos directly from your device library, configure your resize options, and download the output. On iOS and Android devices, you can save the resized images directly to your photos app.

If you need to reduce your image size to a specific file limit like 200kb or 500kb (such as when resizing a passport or visa photo), you can enter the maximum width and height in Step 2. Decreasing picture size by changing the dimensions will usually reduce the overall file size. If the resized image is still larger than your target size, you can adjust the quality slider in Step 2 to lower the output quality. Always check the preview area to ensure the image remains clear and legible. If you do not want to change the dimensions but only want to decrease the file size, use our Image Compressor. While the Image Resizer adjusts the physical width and height dimensions, the Image Compressor is designed to reduce the file size to a target limit (like 200KB) by optimizing compression settings and quality, keeping your image dimensions intact.

Image resizing helps you fit exact width and height requirements for websites, forms, profile pictures, product images, CMS platforms, and social media layouts. This online photo size reducer lets you resize images by exact dimensions or by percentage without installing extra software. If you only want to decrease picture size without changing the visual dimensions, you can use our Image Compressor. If you need to cut out specific parts of the photo, try our Image Cropper.

Resizing your images to consistent dimensions prevents layout shifts and ensures that Shopify stores, e-commerce product listings, blog thumbnails, and galleries load predictably. Using optimized, properly-sized images improves user experience and page speed, which benefits SEO. Combine resizing with the Image Cropper to crop to uniform aspect ratios and the Image Compressor to shrink file sizes further.
