What image formats are supported?

This tool supports all common image formats including JPEG, PNG, GIF, WebP, BMP, and SVG. You can upload any image format your browser supports, and the resized output will be saved as a high-quality PNG file.

Will resizing reduce image quality?

Our resizer uses high-quality image smoothing algorithms to preserve as much detail as possible. When scaling down, quality is generally maintained well. When scaling up, some softness may occur as new pixels are interpolated. For best results, avoid enlarging images significantly beyond their original size.

Is my image uploaded to a server?

No, all image processing happens entirely in your browser using client-side JavaScript. Your images never leave your device and are not uploaded to any server, ensuring complete privacy and security. This also means resizing works offline once the page is loaded.

What is the maximum image size I can resize?

There is no hard limit imposed by our tool, but extremely large images (over 50MB) may cause performance issues or browser memory errors. For best performance, we recommend images under 50MB. The tool can handle dimensions up to 10,000 pixels in width or height.

Can I resize multiple images at once?

Currently, this tool processes one image at a time. After resizing an image and downloading it, you can click "Upload New Image" to resize another image. This ensures each image gets individual attention and optimal quality settings.

What is the difference between resize and compress?

Resizing changes the dimensions (width and height) of an image, while compression reduces file size by lowering quality or using better encoding. Resizing can reduce file size as a side effect of having fewer pixels, but compression focuses specifically on reducing bytes. Use our Image Compressor tool if you want to reduce file size without changing dimensions.

How do I resize images for social media?

Different social platforms have recommended image sizes. For Instagram posts, use 1080x1080 pixels (square). For Facebook posts, use 1200x630 pixels. For Twitter posts, use 1200x675 pixels. For best results, enable "maintain aspect ratio" and resize to these dimensions, or use our preset sizes for common formats like Full HD (1920x1080).

FAQ

Is this image resizer free?

Yes, this tool is 100% free with no limits on usage or file size restrictions.

Is my image data safe?

Absolutely. All image processing happens locally in your browser. Your files are never uploaded to any server, ensuring complete privacy.

What does "maintain aspect ratio" mean?

When aspect ratio is locked, changing the width automatically adjusts the height (and vice versa) to preserve the original image proportions. This prevents distortion and stretching.
