Drop some images above to get started!
Drag and drop one or more images onto the tool, or click to browse your files. Supports JPEG, PNG, WebP, GIF, and BMP formats up to 50 MB per image.
Enter custom width and height in pixels, or select a preset for popular platforms like Instagram (1080x1080), Facebook cover (820x312), YouTube thumbnail (1280x720), or LinkedIn banner (1584x396).
Lock the aspect ratio to prevent distortion, choose between resize or crop mode, and set the output quality. The preview updates in real time so you can see the result before downloading.
Download each resized image individually. The original files are never modified since all processing happens on copies in your browser.
One-click presets for Instagram posts, Facebook covers, Twitter headers, LinkedIn banners, YouTube thumbnails, and Pinterest pins. No need to look up platform-specific dimensions.
Resize multiple images at once to the same dimensions. Upload an entire folder of product photos and have them all sized consistently in seconds.
See exactly how your resized image will look before downloading. Toggle between the original and resized version to compare quality and composition.
Lock the aspect ratio to maintain proportions when changing dimensions. Unlock it for exact pixel dimensions when you need a specific crop.
Adjust output quality from 1-100% to balance file size against image clarity. The file size estimate updates as you move the slider.
Images are resized entirely in your browser using the Canvas API. Nothing is uploaded to any server, keeping your photos private and processing instant.
Social media managers resize content daily for different platforms. A single product photo might need to be sized to 1080x1080 for Instagram, 1200x628 for Facebook link previews, and 1024x512 for Twitter. The preset system eliminates guesswork and ensures every post meets platform requirements without trial and error.
E-commerce sellers prepare product listings that require consistent image dimensions. Marketplaces like Amazon, Etsy, and Shopify each have specific size requirements, and product images that do not meet them look unprofessional or get rejected. Batch resizing lets sellers process entire product catalogs in minutes.
Web developers and designers optimize images for website performance. Uploading a 4000x3000 photo when the layout only needs 800x600 wastes bandwidth and slows page load times. Resizing images to their display dimensions before uploading is one of the simplest performance improvements for any website.
Enlarging images beyond their original resolution can introduce blur since the tool has to create new pixels. Reducing image size generally preserves quality well. The quality slider lets you fine-tune the compression level for the best balance between file size and clarity.
Each image can be up to 50 MB. Since processing happens in your browser, very large images may take a moment depending on your device's performance. For best results with batch operations, keep individual files under 20 MB.
Yes, the aspect ratio lock is enabled by default. When you change the width, the height adjusts automatically to maintain the original proportions. Unlock it only when you need exact non-proportional dimensions.
The resizer supports JPEG, PNG, WebP, GIF, and BMP input files. Output is available in JPEG, PNG, and WebP formats. You can change the format during resize if needed, such as converting a BMP to a compressed JPEG.
No, all resizing happens locally in your browser using the HTML5 Canvas API. Your images never leave your device, which means processing is instant and your photos remain completely private.
