About
Resizes an image by pixel dimensions or percentage, entirely in your browser using the Canvas API. The output keeps the original file format (PNG, JPEG or WebP). Nothing is uploaded.
Change an image to exact pixel dimensions or scale it by a percentage. Keep the aspect ratio locked to avoid distortion, preview the output, and download it in a browser-supported format.
What you can do
- Resizes by width and height or by percentage.
- Optionally locks the original aspect ratio.
- Limits oversized output to safe browser dimensions and processes files locally.
Common uses
- Prepare a hero image or thumbnail for a website.
- Resize an image for a profile or social post.
- Create a smaller copy for documentation or email.
Frequently asked questions
Will resizing stretch my image?
Keep the aspect-ratio lock enabled and the matching dimension will update automatically, preventing accidental stretching.
Is the image sent to a server?
No. Loading, resizing, previewing, and exporting all happen in your browser.
