People also use this image resizer to prepare images for websites, social media, profile pictures, email attachments, online forms, blog posts, product listings, school projects, and uploads with size or dimension limits.
What this tool is useful for
- Prepare a photo at the exact pixel dimensions an upload requires.
- Create a smaller website image from a large original.
- Export the resized image in PNG, JPG or WebP.
Practical example
To reduce a 2400 × 1600 photo to half its dimensions without stretching it, set width to 1200 and height to 800. Select Process Image and inspect the preview before downloading. The saved image will contain fewer pixels; its file size also depends on the output format and image content.
Helpful tips
- Width and height are independent controls: enter proportional values to preserve the original shape.
- Avoid enlarging a small original when sharp detail matters; resizing cannot restore missing detail.
- Choose PNG or WebP for transparency. JPG uses a white background.
- The accepted dimensions are 1 to 16,384 pixels per side; very large images may exceed your browser's memory.
