About this tool
Resize photos and graphics to exact pixel dimensions for websites, documents, marketplaces, email, and social media while controlling whether the original proportions are retained.
With aspect-ratio locking enabled, changing one dimension automatically updates the other based on the source proportions.
Disabling the lock allows any width and height combination, but dimensions with a different ratio will stretch or compress the image.
Frequently asked questions
How do I resize without stretching the image?
Keep Lock aspect ratio enabled. Changing either width or height automatically calculates the matching dimension.
Can resizing improve a blurry small photo?
Increasing dimensions adds pixels but cannot recreate missing detail. For best results, begin with the largest available source.
Is the image sent to a server?
No. Resizing and PNG export take place in your browser.
