Online Image Resizer

Our tool supports the most common image formats including JPEG, PNG, GIF, and WebP. You can upload any of these formats and also convert between them.

Yes, absolutely! Our image resizer processes all images directly in your browser using JavaScript technology. This means:

• Your images are never uploaded to our servers
• No copies of your images are stored anywhere
• We have no access to your images or metadata
• All processing is performed locally on your device

To maintain the best quality when resizing, consider these tips:

• When making images smaller, use the quality slider to adjust the compression (90% or higher for best quality)
• For images with text or sharp details, PNG format often preserves clarity better than JPEG
• WebP format offers a good balance between quality and file size
• Always keep aspect ratio locked when you want to avoid distortion
• Avoid excessive enlargement as it will always reduce quality - try to stay under 200% of the original size

Resizing images has several benefits:

• Faster website loading times - smaller images load quicker, improving user experience and SEO rankings
• Reduced storage usage - save space on your devices and cloud services
• Better social media presentation - each platform has optimal image dimensions for posts
• Email attachments - smaller images are less likely to be blocked by email size limits
• Proper printing dimensions - adjust images to fit specific printing sizes

Pixel resizing allows you to specify the exact dimensions of the output image. This is useful when you need images to fit a specific space, like a website template or a social media profile picture.

Percentage resizing adjusts the image size relative to its original dimensions. For example, resizing to 50% will make the image half its original width and height. This is helpful when you want to maintain the same proportional reduction across multiple images of different sizes.

Here are the recommended dimensions for common social media platforms:

• Facebook: Profile picture (170x170px), Cover photo (820x312px), Shared posts (1200x630px)
• Instagram: Profile picture (110x110px), Square post (1080x1080px), Landscape (1080x566px), Stories (1080x1920px)
• Twitter: Profile picture (400x400px), Header image (1500x500px), Post image (1200x675px)
• LinkedIn: Profile picture (400x400px), Cover photo (1584x396px), Shared posts (1200x627px)
• YouTube: Channel profile (800x800px), Banner (2560x1440px), Thumbnail (1280x720px)

The best format depends on your needs:

• JPEG: Ideal for photographs and images with many colors. Good balance between quality and file size.
• PNG: Best for images with transparency, logos, text, or illustrations with sharp edges. Provides better quality but larger file sizes.
• WebP: Modern format that offers excellent compression while maintaining quality. Great for web use, but not as widely supported in older software.

Currently, our tool processes one image at a time to ensure the highest quality and performance. This approach allows for precise control over each image's settings. If you need to resize multiple images with the same settings regularly, you might consider:

• Using our tool sequentially for each image
• For very large batches, a desktop application might be more suitable
