Pro Tips for Resize Image
Get the most out of your resize image experience
Upscaling
Enlarging images cannot add detail. Keep enlargements under 200% for acceptable results.
Social sizes
Presets for common sizes (1080×1080, 1200×630, 1920×1080) are one click away.
Quality
High-quality downsampling is used, so shrunken photos stay sharp.

Frequently Asked Questions — Resize Image
Everything you need to know about how to resize image online
Will resizing distort my image?
Not with the aspect ratio lock on. Turn it off only if you deliberately want to stretch.
Can I resize many images to the same size?
Yes. Drop them all and choose 'Fit within' or exact dimensions.
Are my files secure while I resize images?
Yes. Everything happens inside your browser using JavaScript and WebAssembly. Your file is never uploaded, and nothing is stored on a server.
Do you keep a copy of my document?
No. The file lives in your browser's memory only. When you close or refresh the tab it is gone. We cannot see it, and neither can anyone else.
