How to use the Image Resizer

Image Resizer handles your images right in your browser. Pick a file, adjust the settings, and see previews update in real time. Your images never leave your device — complete privacy.

Why use the Image Resizer

Image Resizer gives you the confidence that your images are not being stored, analysed, or used by a third-party service. For photographers, designers, and developers working with client assets, this privacy guarantee is essential. The tool simply reads the file, processes it in your browser, and discards it when you close the tab.

When to use Image Resizer

Reach for Image Resizer during content creation when you need to quickly optimise images for the web. Reduce file size without visible quality loss, convert to modern formats, and add metadata — all in your browser without launching a full image editor or relying on an online service that stores your uploads.

Key features of Image Resizer

Image Resizer processes images entirely in your browser using Canvas APIs, so your files never reach a server. You get unlimited file size, instant processing, and complete privacy — ideal for sensitive or proprietary image assets.

Common use cases for Image Resizer

Image Resizer is used when: converting a screenshot from PNG to JPEG to reduce file size before attaching it to a support ticket; resizing product photos to match e-commerce platform dimension requirements; and stripping EXIF metadata from images before sharing them publicly.
