Resize Images Online in Seconds

Resizing an image isn't just about making it smaller. Whether you're preparing a photo for social media, reducing dimensions for a website, or adjusting an image for email, using the correct size helps maintain quality while meeting platform requirements.

Our Image Resizer lets you resize, rotate, flip, and convert images directly in your browser. Everything happens locally on your device, so your images stay private throughout the entire process.

Why Image Size Matters

Different platforms require different image dimensions. Uploading the wrong size can lead to blurry images, unwanted cropping, or stretched graphics.

If you're searching for how to resize images for Instagram, resize photos for Facebook, or change image dimensions for a website, using dedicated resizing tools saves time while producing better-looking results.

Instead of guessing dimensions manually, our tool provides ready-made presets for popular platforms.

Resize Images Your Way

The tool offers multiple ways to resize an image depending on your needs.

Resize by Pixels

Enter an exact width and height when you need precise dimensions for websites, presentations, or digital projects.

Resize by Percentage

Want a smaller version without calculating dimensions?

Simply resize the image by a percentage, such as 50% or 75%.

This is ideal for reducing image dimensions while keeping the same proportions.

Ready-Made Social Media Presets

Creating content for multiple platforms becomes much easier with built-in presets for:

• Instagram

• Facebook

• YouTube

• LinkedIn

• Pinterest

• TikTok

• Twitter (X)

• WhatsApp

Each preset automatically applies the recommended dimensions, helping you prepare images faster.

Rotate, Flip, and Convert Images

Sometimes resizing isn't enough.

Our Image Resizer also allows you to:

• Rotate images by 90°, 180°, or 270°

• Flip images horizontally

• Flip images vertically

• Convert images to JPG

• Convert images to PNG

• Convert images to WebP

These features help prepare images for websites, social media, documents, or presentations without switching between multiple editing tools.

If you also want to reduce file size after resizing, try our Image Compressor.

Maintain the Right Dimensions

The built-in aspect ratio lock automatically keeps your image proportional while you edit width or height.

When using a social media preset, the tool intelligently unlocks the ratio so platform-specific dimensions can be applied exactly as required.

For users who need to calculate custom proportions before resizing, our Aspect Ratio Calculator can help determine the correct dimensions.

Private Image Processing

Privacy matters, especially when working with personal or business images.

Unlike many online services, this Image Resizer performs all processing directly in your browser.

That means:

• Images are never uploaded.

• No files are stored on external servers.

• Your photos remain on your own device.

• The tool continues working after loading, even without an internet connection.

Tips for Better Image Quality

For the best results:

• Resize from the original image whenever possible.

• Avoid enlarging very small images.

• Use PNG for graphics with transparency.

• Choose JPG for photographs.

• Select WebP when optimizing images for websites.

• Use exact social media presets to prevent unwanted cropping.
