FAQ
Frequently asked questions
Everything you need to know about the Image Resizer.
Back to the toolHow do I resize an image?
Add your image, pick a preset or type the width and height you want, then click Download. You can resize many images at once.
What is the difference between Fit and Crop?
“Fit” keeps the whole picture and adds a background color around it. “Crop” fills the exact size and trims the edges that don’t fit.
What size is an Instagram post?
A square Instagram post is 1080 × 1080 px, a portrait post is 1080 × 1350 px and a story or reel is 1080 × 1920 px — all available as presets.
Will resizing reduce quality?
Making an image smaller keeps it sharp. Enlarging a small image beyond its original size can make it look soft.
Are my images uploaded?
No. Resizing happens on your device, so your photos stay private.
