About the Image Resizer
Our free online image resizer lets you change the width and height of any PNG, JPEG, or WEBP image in just a few clicks. Whether you need to shrink a photo for a website, fit an image to a specific size for social media, or scale up a graphic for print, this tool gives you precise, pixel-perfect control over the final dimensions.
Unlike most online tools, resizing happens entirely inside your browser using the HTML5 Canvas API — your image is never uploaded to a server. That means it's fast, works without an internet round-trip, and keeps your files completely private and secure.

Frequently Asked Questions
Is my data safe?
Yes. Resizing happens entirely in your browser using the HTML5 Canvas API — your image is never uploaded to a server, so it stays completely private.
What image formats are supported?
You can upload most common image formats and export the resized result as PNG, JPEG, or WEBP.
Does it cost money?
No. The resize tool is 100% free to use, with no registration or account required.
Will resizing reduce my image quality?
Resizing to smaller dimensions typically reduces file size with minimal visible quality loss. Enlarging an image beyond its original size may introduce some blurriness, since no new detail can be created.
