1FileTool vs Squoosh
Squoosh already keeps your images in the browser. The difference shows up at the second image.
1FileTool
1FileTool is a native desktop app with 37 image tools among 265+ total. Drop a folder, compress or convert every file in it, and see the size before and after for each one — with a file that grew flagged in amber instead of buried in the total. Save the settings as a recipe, or attach them to a watched folder and stop thinking about it.
Squoosh
Squoosh is Google’s image compressor, and it is a genuinely clever piece of engineering: the codecs are compiled to WebAssembly and run inside your browser tab, so your images are not uploaded. The visual before/after slider is the best way to eyeball quality trade-offs that exists. It handles one image at a time, and it only does images.

The verdict
There is no single winner — it depends on what you need.
Choose 1FileTool if…
- You have a folder of images, not one image.
- You want the same compression settings applied again next week without re-deciding them.
- You also need to resize, strip EXIF, convert, or remove a background.
- You want a watched folder to handle exports the moment they land.
Choose Squoosh if…
- You are tuning one hero image and want to see the quality trade-off with your own eyes.
- You want zero install and zero cost.
- You are on a borrowed machine.
- You want to compare codec output side by side before committing to a setting.
Frequently asked questions
Does Squoosh upload my images?
No, and it deserves credit for that — Squoosh runs its codecs in your browser through WebAssembly, so the image never leaves the tab. On privacy the two tools agree. They differ on how many images you can put through at once.
Is there a batch version of Squoosh?
Not in the app itself. There is a command-line package for scripted use, but the web app is one image at a time. 1FileTool takes a whole folder, processes files in parallel, and reports each one’s size before and after.
Why pay when Squoosh is free?
If you compress one image a week, do not. The case for 1FileTool is volume and repetition — folders instead of files, saved recipes instead of re-picking settings, watched folders instead of remembering, plus 228 tools for everything that is not an image.
Does 1FileTool have a visual quality slider?
No. Squoosh’s side-by-side slider is better for eyeballing a single image than anything 1FileTool offers. 1FileTool reports the numbers — original size, new size, exact percentage saved — which is the more useful readout across fifty files.
