Resize Image

Simply upload your image, then enter new width and height (or choose a preset size). Check "Maintain aspect ratio" to keep proportions. Click "Apply Resize" to see the result, then download your resized image. No registration required!

We support JPG, JPEG, PNG, WebP, and GIF formats. Maximum file size is 50MB. You can also export your resized image as JPG, PNG, or WebP with adjustable quality settings.

Maintaining aspect ratio keeps your image's proportions (width to height ratio) when resizing. When enabled, changing width automatically adjusts height, and vice versa. This prevents your image from looking stretched or squashed.

For web use: Full-width hero images: 1920x1080px, Blog post images: 1200x630px, Thumbnails: 800x800px or 640x480px, Social media: 1024x1024px for Facebook/Instagram, 1024x512px for Twitter/X. Use our preset sizes for quick selection!

Resizing down (making smaller) usually doesn't affect visual quality. Resizing up (making larger) can cause blurriness as the software has to add new pixels. For best results, start with the largest size you need and resize down as required.

No! Your images never leave your device. All resizing happens locally in your browser using HTML5 Canvas. This means 100% privacy, no upload delays, and complete security for your sensitive images.
