Privacy Policy

1. Overview

Resizeify (“we”, “our”, “the tool”) is a free, browser-based image resizing and compression utility. This Privacy Policy explains what information we collect, how we use it, and the choices you have.

Because all image processing runs entirely on your device using the browser’s built-in HTML5 Canvas API, we are structurally incapable of accessing, storing, or transmitting your image files — even if we wanted to.

2. Image & Document Processing

All file operations — resizing by pixel dimensions, compressing to a target file size, format conversion (JPG, PNG, WebP, HEIC), and any other transformation — are performed 100% locally inside your web browser. Specifically:

• Your image files are read directly from your local device via the browser File API.
• Pixel manipulation is performed using HTMLCanvasElement and the Canvas 2D rendering context — browser-native technology that requires no network connection.
• The processed image is written to a temporary Blob URL in browser memory and offered as a direct download. It is never serialised and sent over the network.
• HEIC conversion uses heic2any, a JavaScript library that also runs entirely client-side. No HEIC data leaves your device.
• EXIF metadata embedded in your photos (GPS coordinates, camera model, timestamps, etc.) is neither read nor transmitted by Resizeify.
• When you close or navigate away from Resizeify, all temporary Blob URLs are revoked and the image data is discarded from memory. Nothing persists.

3. Data We Do Collect

Resizeify itself does not collect, store, or transmit any personal information. However, the following third-party services operate on this site and may collect anonymous usage data:

3a. Vercel Analytics

This site is hosted on Vercel. Vercel Analytics collects anonymous, aggregated page-view data (page URL, referrer, country, device type) to help us understand how the site is used. No personally identifiable information is collected. See Vercel’s Privacy Policy for details.

3b. Google AdSense & Advertising

Resizeify uses Google AdSense (publisher ID: ca-pub-1435687773201080) to display advertisements. Google AdSense may use cookies and similar tracking technologies to serve ads that are relevant to your interests based on your browsing history across sites.

4. Cookies

Resizeify itself sets only one first-party cookie: a small theme preference cookie (theme) that records whether you have selected light or dark mode. This cookie contains no personal information and never leaves your browser.

Google AdSense may set third-party cookies as described in Section 3b above.
