About Free Image Tools

A free, browser-based image toolset built for people who work with images daily and value their privacy.

๐Ÿ”’

Everything runs in your browser

Your image files are processed locally using the Canvas API and FileReader API. Nothing is uploaded to a server. Not ever.

Why this site exists

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 โ€” but you also get complete privacy.

What you can do here

The site covers three main categories of image work, plus a set of specialty tools for specific tasks:

Compress

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 โ†’

Convert

Convert between JPG, PNG, WebP, AVIF, GIF, and BMP. Includes dedicated converters for common pairs like WebPโ†’JPG and PNGโ†’WebP.

Resize

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.

AI Alt Text

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.

Specialty tools

Beyond the main tools, there are focused utilities for specific tasks:

Our privacy commitment

All image processing on this site โ€” compression, conversion, resizing, cropping, and color extraction โ€” runs entirely inside your web browser. Here is exactly how:

  • FileReader API reads your image file into browser memory. The file data never leaves your computer at this step.
  • Canvas API renders, resizes, and re-encodes the image. The browser handles the compression codec natively.
  • Blob URLs provide a download link pointing to data that exists only in your browser tab. Closing the tab deletes it.

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 โ€” 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.

Supported formats

The tools work with the following image formats as input:

JPG / JPEG
Photos, gradients
PNG
Transparency, graphics
WebP
Modern web format
AVIF
High compression
GIF
Short animations
BMP
Uncompressed 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+.

Who built this

Free Image Tools is built and maintained by Rui Bian, an independent developer who got tired of uploading images to cloud services for routine tasks. The project began with one practical goal: make common image work fast, private, and available without installing software or creating an account.

The site is hosted on Cloudflare Pages and is free to use. It may use clearly separated advertising to help cover hosting and maintenance, but ads never change the output of a tool or receive the images processed by the browser-only tools.

Open source project

FreeImgTools is open source under the MIT License. The public repository includes the browser tools, guide pages, Cloudflare Pages Functions, sitemap, redirects, and project documentation.

Developers can review the code, suggest improvements, report bugs, or contribute focused privacy-friendly workflows on GitHub. Public issues are best for product feedback; security-sensitive reports should be sent privately through the contact options.

How the tools are tested

Every release is checked in current desktop and mobile browser layouts before it is published. For processing tools, the test is not limited to whether a button responds: the downloaded file must open, use the selected format, and report the expected dimensions or target size.

  • Input and output checks: sample JPG, PNG, WebP, AVIF, GIF, and PDF files are used where the browser supports them.
  • Result checks: dimensions, MIME type, file size, filenames, transparency, and multi-file ZIP downloads are inspected.
  • Privacy checks: browser-only tools are reviewed for unexpected image upload requests; AI features are treated separately because inference requires a server request.
  • Page checks: internal links, canonical URLs, structured data, mobile overflow, dark mode, and browser console errors are tested.

Browser image encoders are not identical, so two browsers can produce slightly different file sizes at the same quality setting. Target-size compression therefore reports the actual result instead of promising an exact byte count that every browser cannot guarantee.

Guide and correction policy

Guides are written for a task a user can complete, not merely to create another search page. Platform specifications are checked against first-party documentation when available, examples are written for this site, and materially updated guides receive a new review date. When a platform changes its requirements, the related tool preset and guide should be updated together.

Corrections are welcome through the Contact page or GitHub Issues. Please include the affected URL and, for a specification change, a first-party source. Last reviewed: July 13, 2026.
