About FreeTinyPNG

Our mission

FreeTinyPNG was built around a simple belief: basic image tools should be free, fast, and private. Every web designer, blogger, marketer, and student needs to compress and convert images, and yet the most popular tools online either charge a subscription, impose strict file-size limits, or upload your private images to a remote server.

We do none of those things. Every tool on this site runs entirely inside your browser. Your files never leave your device, there is no signup, and there is no usage limit beyond what your own hardware can handle.

[!NOTE] Trademark Disclaimer: FreeTinyPNG.org is an independent browser-based image processing service. We are not affiliated with, sponsored by, or associated with TinyPNG or Tinyify. All tools and software on this site are engineered independently.

What we offer

We focus on a small set of tools, done well:

• Image compression for PNG and JPG, including bulk processing.
• Format conversion between PNG, JPG, and the modern WebP format.
• In-depth guides and tutorials explaining how image formats work and how to choose the right one for your project.

We deliberately keep the toolset small. We would rather have three excellent tools than thirty mediocre ones. If a tool is on this site, you can trust that it has been thought through carefully.

How we work

Our tools are built on three principles:

Privacy first. All processing is performed in the browser using the native Canvas and WebAssembly APIs. We have no servers that handle your image data. We couldn’t see your files even if we wanted to. You can confirm this yourself by opening your browser’s Developer Tools and watching the Network tab as you process a file.

No artificial limits. We don’t gate features behind paywalls or restrict the number of files you can process per day. The web should be a place where useful tools are available to everyone.

Honest engineering. Compression is governed by the laws of information theory. We don’t promise impossible savings, and we don’t recompress files in ways that would degrade them invisibly. When a file can’t get smaller without losing quality, we tell you.

How we’re funded

FreeTinyPNG is supported by display advertising shown alongside the tools and articles. We do not sell user data, place tracking pixels for third-party advertisers, or operate any subscription tier. Ads pay for the domain, hosting, and the time it takes to write and maintain the site.

If our advertising ever begins to interfere with the tools (slow page loads, intrusive overlays, deceptive placements), we consider that a bug and want to hear about it. Email us at [email protected].

Meet the team

FreeTinyPNG is built, written, and maintained by a group of web performance enthusiasts and front-end developers. We deal with media library optimization, CDN caching, and Core Web Vitals in our day jobs, and we created this project to make simple, browser-based, privacy-first image compression and conversion tools accessible to everyone.

Our editorial standards

Every guide and article on this site is written and reviewed by our team members. We:

• Verify every technical claim and test our code examples before publication.
• Cite primary sources (W3C specifications, browser documentation, academic papers) where appropriate.
• Update articles when the underlying browser APIs or image format support expands.
• Disclose limitations and trade-offs honestly. We don’t promise impossible file size savings and explain what our browser-based Canvas tools can and cannot do.

Contact us

We welcome questions, feedback, bug reports, and suggestions. The best way to reach us is by email at [email protected], or via the form on our contact page.

If you found an issue with a tool, please include:

• Which tool you were using.
• Your browser and operating system.
• The approximate size and format of the file you were processing.
• A description of what went wrong and what you expected to happen.

We aim to respond to every email within a few business days.
