Image Optimize vs Squoosh
Squoosh is an excellent single-image editor made by Google. But the moment you need to optimize more than one image, it falls short. Here's how Image Optimize fills that gap.

Where Image Optimize pulls ahead
Batch — Squoosh's biggest gap
Squoosh is a phenomenal single-image editor. But it only ever handles one image at a time, with no bulk output. Image Optimize lets you drop in up to 20 files, optimize them all with one click, and download everything as a ZIP.
One ZIP, done
After optimizing in Squoosh you save each image individually, one at a time. Image Optimize packages all your results into a single ZIP so you can move on in seconds instead of minutes.
Made for repeatable workflows
Image Optimize remembers your preferred format, quality, and width settings across sessions. Squoosh resets each time. If you're running the same optimization workflow repeatedly, Image Optimize is built for you.
History that stays with you
Image Optimize saves your recent optimization history directly in your browser. Squoosh has no history tracking; once you close the tab, that context is gone. Image Optimize lets you see exactly what you've optimized and how much you've saved over time, all stored privately in your browser.
Consistent results, any device
Squoosh processes images locally — "images never leave your device" is a genuine privacy win. The trade-off is that performance depends entirely on your browser and hardware, which can be slow on large files. Image Optimize processes server-side for consistent throughput regardless of your device.
When Squoosh is the right tool
We believe in being honest. Squoosh is a genuinely great tool and the right choice in some situations:
- You need advanced per-codec controls (OxiPNG levels, MozJPEG tuning, etc.)
- You have privacy requirements that prevent any file uploads to a server
- You're optimizing a single image as a one-off task
- You want a completely free tool with no usage limits
For everything else — recurring workflows, batches of images, and cross-platform consistency — Image Optimize is the faster choice.
Optimize 20 images in the time Squoosh does one

Start optimizing freeFrequently asked questions
Squoosh is free — why would I pay for Image Optimize?
You don't have to. Image Optimize has a generous free tier: 20 optimizations a day with no account needed. The key difference isn't price — it's batch processing. If you need to optimize more than one image at a time, Squoosh can't do it, but Image Optimize can.
Squoosh has more codec options. Does that matter?
For power users tweaking codec parameters, yes. For most workflows — web images, app assets, marketing content — the quality slider in Image Optimize gets you where you need to be without the complexity. We expose the controls that matter most.
Squoosh keeps images on my device. How do you handle privacy?
Your files are transmitted over HTTPS, used only to perform the optimization, and are not stored after processing. Squoosh's client-side model is a genuine privacy advantage — if that's a hard requirement for you, it's the right tool. If batch throughput matters more, Image Optimize is the better fit.
Can I use Image Optimize without creating an account?
Yes. The free tier requires no account and no credit card. You get 20 optimizations per day, 5 files at a time, and up to 5 MB per file. Create an account to unlock higher limits.
Does Image Optimize keep a record of what I've optimized?
Yes. Image Optimize stores your recent optimization history locally in your browser, so you can redownload your optimized images if needed. No account is needed and images are never saved on a server. Squoosh has no history tracking at all, so once you close the tab your results are gone.
