How to resize images online
Resize any photo to exact pixel dimensions or pick from our built-in social media presets — Instagram square, Facebook cover, Twitter header, YouTube thumbnail and more. The aspect ratio is locked by default so your image won't stretch or distort.
Drop one or more images above. Enter your target width or height — or pick a preset — and we'll process the files instantly in your browser. Choose your output format (JPG, PNG, or WebP) and download.
Tips for resizing
- Going smaller is great. Shrinking images keeps quality and reduces file size.
- Going bigger has limits. Upscaling beyond the original dimensions makes images soft.
- Lock the ratio. Keeps people's faces and landscapes looking natural.
- Use WebP for the web. Smaller files, same visual quality as JPG.
