Why Use an Online Image Resizer?

Whether you are uploading a profile picture, submitting a document for a job application, or optimizing images for a website, you often face strict dimension and file size limits. Using an image resizer allows you to instantly adjust your photos without needing desktop software like Photoshop. You can resize image online free directly from your browser.

Many online forms require files to be under a specific size. If you need to resize an image to 100KB, resize an image to 50KB, or even resize an image to 20KB, the most effective way is to reduce its pixel dimensions. By lowering the width and height, you directly reduce image size in KB. Our tool lets you resize pixel dimensions by exact numbers or by percentage, ensuring your images meet any requirement while maintaining the best possible quality. All processing happens locally, ensuring 100% privacy.

How to Resize an Image Online

  1. Upload Your Images: Drag and drop your JPG, PNG, or WebP files into the upload zone. You can batch upload up to 50 images at once.
  2. Choose Resize Mode: Select "PX" to enter exact Width and Height in pixels, or select "%" to scale the image by a percentage (e.g., scaling by 50% halves the dimensions).
  3. Adjust Settings: If using pixels, toggle the link icon to lock the aspect ratio so your image doesn't stretch. Check "Don't enlarge" to prevent small images from becoming pixelated.
  4. Resize and Download: Click the "Resize Images" button. Check the new file size in KB on the image cards, then click "Download" or "Download All".
