What is image resizer?
Resizing changes the pixel dimensions of an image. Sellers and creators resize photos every day — for marketplaces (Etsy, Amazon), social platforms (Instagram, Pinterest, Facebook), and document requirements.
Unlike uploading to a web service, this resizer processes the image entirely on your device. Nothing is transmitted, logged, or stored.
How to image resizer
- Drop or click to choose an image.
- Enter a width and height in pixels, or pick a preset such as Instagram post 1080×1080.
- Keep aspect ratio locked to avoid distortion.
- Compare before and after, then download.
Frequently asked questions

Instagram, Facebook, Twitter/X, YouTube, Pinterest, and Etsy dimensions — with more coming soon.
Will resizing reduce my image quality?
