TinyTool vs Squoosh
Squoosh is an open-source image compression app built by Google Chrome Labs that runs entirely in the browser using WebAssembly codecs.
Both TinyTool and Squoosh take the same fundamental stance: image compression should happen in your browser, not on a server. Your files stay private, results are instant, and there are no upload limits. So why might you choose one over the other?
Squoosh is a focused, opinionated compression tool from Google Chrome Labs. It uses high-quality WebAssembly implementations of codecs like MozJPEG, OxiPNG, WebP, AVIF, and JPEG XL to deliver best-in-class compression. Its side-by-side before/after view and granular per-codec sliders make it the favourite of developers and designers who want maximum control over output quality and file size.
TinyTool's image compressor trades some of that fine-grained control for breadth and convenience: batch compression across multiple files at once, format conversion in the same workflow, and access to 80+ other tools — image resizing, background removal, OCR, PDF tools, QR codes, and developer utilities — all from one place. If compression is part of a larger workflow rather than the whole task, TinyTool keeps everything in one tab.

Privacy advantage
TinyTool processes everything 100% in your browser. Your files are never uploaded to any server. No account needed, no usage limits, and no data collection. When you close the tab, your data is gone.
The verdict
Choose Squoosh when you need the absolute best compression quality for a single image and want detailed codec control — it is the gold standard for that use case. Choose TinyTool when you need to compress multiple images at once, work within a larger image or PDF workflow, or want one tab that handles everything from compression to QR codes to JSON formatting.
Frequently asked questions
Does Squoosh upload images to Google servers?
No. Despite being made by Google, Squoosh is fully client-side and open source. Your images stay in your browser. TinyTool takes the same approach — both tools are safe for sensitive images.
Why is Squoosh compression sometimes better than TinyTool?
Squoosh uses WebAssembly builds of best-in-class codecs like MozJPEG and OxiPNG, which are fine-tuned specifically for maximum compression efficiency. TinyTool uses the browser's built-in Canvas API, which is faster and more compatible but may produce slightly larger file sizes at the same quality setting for some images.
Can TinyTool batch-compress images like Squoosh cannot?
Yes. TinyTool lets you drop in multiple images at once, compress them all in one click, and download the results as a ZIP archive. Squoosh processes one image at a time. For compressing a folder of photos or a set of assets, TinyTool saves significant time.
Is Squoosh still actively maintained?
Squoosh is open source and has seen reduced active development in recent years. TinyTool is actively maintained with regular tool additions and updates. For the core compression task both tools work reliably today.
