TinyPNG vs Squoosh: Best Image Compressor Compared in 2026

TinyPNG and Squoosh are two of the most widely used image compression tools. Both are free, but they take very different approaches. Here is a detailed comparison.

Compression Quality

We tested both tools with 50 images. TinyPNG consistently reduces file sizes by 60-80% with minimal visible quality loss. Squoosh offers more control with adjustable quality sliders and multiple compression algorithms. For most users, TinyPNG produces better results out of the box, while Squoosh gives professionals more control over the compression settings.

Privacy Comparison

Squoosh runs entirely in your browser, processing images locally without uploading them to any server. This makes it ideal for sensitive or confidential images. TinyPNG uploads images to its servers for processing, which may be a concern for privacy-conscious users. TinyPNG states that uploaded images are deleted after processing, but the images do leave your computer.

Supported Formats

TinyPNG supports PNG, JPEG, and WebP. Squoosh supports JPEG, PNG, WebP, AVIF, and JPEG XL. Squoosh also lets you convert between formats, which TinyPNG does not offer in its free version. If you need AVIF compression, Squoosh is the clear winner.

Verdict

Use TinyPNG for quick, high-quality compression of JPEG and PNG images without adjusting settings. Use Squoosh when you need more control, privacy, or support for modern formats like WebP and AVIF. For most website owners, both tools are excellent, and you can use both depending on the task.
