About this tool
Free Image Resizer to Exact Dimensions
Use this free Image Resizer to Exact Dimensions to change the width and height of JPG, PNG, and WebP files directly in your browser. Enter custom pixel dimensions or choose a useful preset for a square profile image, passport-style photo, Instagram post, YouTube thumbnail, or Facebook sharing image. The tool creates an output file with the exact width and height you select, then shows a preview, final dimensions, file size, format, and resize mode before download. An aspect-ratio lock helps you resize an image without distortion. When the lock is enabled, changing the width automatically calculates the matching height from the original image, and changing the height updates the width. Unlock the ratio when a website, application form, marketplace, or social platform requires a fixed size such as 300 by 300 pixels, 600 by 600 pixels, 1080 by 1080 pixels, or 1280 by 720 pixels. Choose Crop to Fill when the output frame must be completely filled without stretching. The resizer keeps the image proportions and crops equal areas from the center when necessary. Choose Fit with Padding when the complete image must remain visible inside the exact canvas; unused space remains transparent for PNG and WebP or white for JPG. Stretch to Fill forces the image into the requested dimensions and may distort objects when the original and target aspect ratios differ. JPG is widely supported and works well for photographs, forms, websites, and email. PNG is useful for graphics, screenshots, text, and transparent images, although PNG quality is lossless and the quality slider does not apply. WebP often creates efficient files for modern websites while supporting transparency. Output quality controls are available for JPG and WebP so you can balance visual detail and file size. All resizing happens locally on your device. The selected image is not uploaded to WebToolsEdge for processing. This makes the tool suitable for personal photographs, application images, product pictures, document scans, and other files you prefer to keep private. For a strict upload limit after resizing, continue with the Image Compressor to Specific KB to reduce the resized file below a required maximum.
Start by removing unwanted edges with the Image Cropper Online, then reduce the resized download below a strict upload limit with the Image Compressor to Specific KB.

How do I resize an image to exact dimensions?+

Yes. Select the 300 × 300 preset or enter 300 for both width and height.
How can I resize an image without distortion?+
Keep the aspect-ratio lock enabled for proportional dimensions, or use Crop to Fill or Fit with Padding for a fixed frame.
