About ChangeSizeImage

ChangeSizeImage was built on a simple idea: everyone should be able to resize, compress, and convert images without giving up their privacy.

Most online image tools force you to upload your files to a remote server. That means your personal photos, business assets, or client work sit on someone else's hard drive — often in another country — with no clear idea of who can access them or for how long.

We do things differently. Every single pixel of your image stays on your device. Our tools run entirely in your browser using modern web technologies. Your files never touch our servers. We literally cannot see your images even if we wanted to.

Privacy isn't a feature we bolted on — it's the foundation everything is built on.

• No uploads — all processing happens locally in your browser
• No accounts — we don't ask for your email, name, or any personal info to use the tools
• No storage — we have zero servers dedicated to storing user images
• No tracking of your images — we only collect anonymized usage stats via Google Analytics to improve the site

This approach means you can process sensitive images — client headshots, confidential documents, personal photos — with complete peace of mind.

ChangeSizeImage is a client-side web application built with modern JavaScript and WebAssembly technologies. When you drag an image into our tool:

1. The image loads into your browser's memory (not our server)
2. Our code processes the image using your device's CPU
3. The result is generated and offered for download
4. When you close the tab, the image data is gone — we never had a copy

This is the same technology that powers offline-capable apps. The only difference is you access it through your browser instead of installing software.

Our platform includes three core tools, each designed to handle a specific image editing need:

We understand that trust is earned, not given. Here's what we do to earn yours:

• Transparent practices — our Privacy Policy and Terms of Service are written in plain English, not legalese
• Open about tracking — we use Google Analytics and AdSense, and we tell you exactly what data is collected and how to opt out
• Cookie consent — we ask for your permission before enabling non-essential cookies, as required by EU law
• No dark patterns — we don't trick you into signing up, subscribing, or sharing data you didn't intend to
• Responsive support — reach us via our contact form or on X (Twitter)

We're always listening. Whether you have a feature request, found a bug, or just want to say hello, we'd love to hear from you.
