A free, browser-based image toolset built for people who work with images daily and value their privacy.
Web developers, designers, and content creators need to compress, resize, or convert images constantly. The typical workflow involves either downloading desktop software, uploading files to a cloud service, or dealing with ad-heavy tools that require creating an account just to export a single file.
None of those options are great. Desktop software is often expensive or platform-specific. Cloud-based tools require trust that your images won't be stored, shared, or used to train models. Free alternatives are frequently slow and cluttered.
Free Image Tools was built to fill a specific gap: a fast, clean, browser-based toolset that covers the most common image tasks without requiring you to hand over your files. The trade-off is that you get no cloud storage, no history, and no account — but you also get complete privacy.
The site covers three main categories of image work, plus a set of specialty tools for specific tasks:
Reduce file size by adjusting quality. Target a specific file size (under 200KB, under 500KB) or let the tool find the best quality-to-size ratio for your use case.
Open compressor →Convert between JPG, PNG, WebP, AVIF, GIF, and BMP. Includes dedicated converters for common pairs like WebP→JPG and PNG→WebP.
Open converter →Resize to exact pixel dimensions or scale by percentage. Lock aspect ratio or stretch freely. Includes presets for common targets like US visa photos and Discord emoji sizes.
Open resizer →Generate descriptive alt text for images using Cloudflare AI. Useful for accessibility audits and speeding up image tagging workflows. The AI model describes what it sees in the image.
Open AI tools →Beyond the main tools, there are 11 specialty tools for specific tasks:
All image processing on this site — compression, conversion, resizing, cropping, and color extraction — runs entirely inside your web browser. Here is exactly how:
The one exception is the AI Alt Text feature. Generating alt text requires sending the image to an AI model running on Cloudflare's edge network. Cloudflare processes the image in memory and returns a text description — no image is stored after inference completes. If you are working with sensitive images, use the browser-only tools instead.
We do not set tracking cookies, fingerprint browsers, or collect image content. See our Privacy Policy for full details.
The tools work with the following image formats as input:
Output format support depends on what your browser can encode. All modern browsers support JPEG, PNG, and WebP output. AVIF output requires Chrome 94+ or Firefox 113+.
Free Image Tools is a small independent project. It was built by a developer who got tired of uploading images to cloud services to do routine tasks, and wanted something fast and private that ran entirely in the browser.
The site is hosted on Cloudflare Pages and is free to use. It is supported by Google AdSense ads, which appear on the page but do not affect how the tools work.
