The Squoosh alternative that takes the whole folder
Squoosh keeps your image in the browser and shows you a beautiful quality slider — for one image. 1FileTool takes the folder, compresses every file locally, and tells you exactly what each one saved.

Why people look for a Squoosh alternative
Squoosh is Google’s image compressor. Its codecs are compiled to WebAssembly and run inside your browser tab, so images are not uploaded, and its side-by-side quality slider is the clearest way to judge a compression trade-off. It works on one image at a time and does images only.
One image at a time
Squoosh is built around inspecting a single image closely. That is the right design for a hero image and the wrong one for the forty screenshots in your export folder.
Settings you re-pick every time
There is nowhere to save “this is how we compress blog images” so the next person — or you next month — makes the same decisions from scratch.
Images only
The PDF, the screen recording and the audio file in the same handoff need a different tool each. Squoosh does one job well and stops there.
Nothing to automate
No watched folder, no recipe, no way to have the work happen when files land. Every batch is a manual batch, one file at a time.

Why switch to 1FileTool
- Compress a folder in one run instead of opening images one at a time.
- See the exact percentage each file saved, with a file that grew flagged rather than hidden.
- Save the settings as a recipe so the next batch is one click.
- Point a watched folder at your exports and stop doing it manually.
- Resize, convert, strip EXIF and remove backgrounds in the same app.
Frequently asked questions
Common questions about switching from Squoosh to 1FileTool.
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 volume.
Is there a batch version of Squoosh?
Not in the web app. A command-line package exists for scripted use, but the app itself handles one image at a time. 1FileTool processes a folder in parallel with per-file progress.
Why pay when Squoosh is free?
If you compress one image occasionally, do not. The case for 1FileTool is repetition — folders instead of files, saved recipes instead of re-deciding, watched folders instead of remembering — plus 248 tools for what is not an image.
Does 1FileTool have a visual quality comparison?
No. Squoosh’s slider is better for judging one image by eye. 1FileTool reports the numbers instead — original size, new size, exact percentage saved — which is what you actually need across fifty files.
Does 1FileTool work offline?
Yes, completely, as an installed app. Squoosh needs the page loaded first, though it works from cache afterwards.
