About Image Resizer
Resize images by exact pixel dimensions or down to a target file size in KB, entirely on your device. Lock the aspect ratio to resize proportionally, or set an exact width and height, then export as PNG, JPG or WebP. Perfect for shrinking large photos for a website, meeting an upload size limit, or preparing consistent thumbnail dimensions.
- Resize by exact width/height or aspect-locked scale
- Target a specific file size in KB automatically
- No upload — resizing happens in your browser
Frequently asked questions
How does target-file-size resizing work?
The tool adjusts JPG/WebP quality (and dimensions if needed) and re-encodes the image repeatedly until it lands at or under your target size in KB.
Will resizing distort my image?
Not if you keep "Lock aspect ratio" enabled — the tool scales width and height together so proportions stay correct.
