Image Resizer
Resize images by exact pixel dimensions or to a target file size in KB — all processing happens on your device
Resize images by exact pixel dimensions, by percentage, or down to a target file size in KB, entirely on your device. Aspect ratio is always preserved, so your images never get stretched or squashed. Set a width or height in pixels, scale by a percentage, or let the tool auto-adjust quality to hit a target size, 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 pixels or by percentage — aspect ratio always locked
- 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?
No — aspect ratio is always preserved, whether you resize by exact pixels or by percentage, so your image never gets stretched or squashed.
