Image A Squoosh alternative for whole folders and exact file sizes
Compress a whole folder of images to a size limit in one go, in your browser like Squoosh, with the results downloaded together as a ZIP.
Drag files here, or
JPEG, PNG, WebP, AVIF and GIF. Decoded on your device, never uploaded.
Encodes at quality 76, tuned to be indistinguishable from the original at normal viewing size. This is the setting to use when you just want the file smaller.
Optional. Height follows automatically.
Ready. Runs locally on your device.
Your files stay on your device. The tool works directly in your browser, using your device to process your files. Nothing is sent to our servers, and we never receive, store, or see your files or figures.

Reembun. (2026, September 11). A Squoosh alternative for whole folders and exact file sizes. https://reembun.com/squoosh-alternative
How to use it
Drop the whole folder in
As many images as you have. Each is compressed in turn by your browser, like Squoosh, without an upload.
Choose how to compress
Smart picks a sensible quality for each image, By quality gives you one slider for all, and To a file size works backwards from a limit such as 200 KB.
Pick the format and maximum width
WebP and AVIF beat JPEG on size. Setting a maximum width shrinks oversized photos before they are compressed, which is often the bigger saving.
Download them all
Every image shows its before and after size, and the lot downloads as one ZIP.
Two good tools for two different jobs
Squoosh deserves its reputation. It is open source, it compresses in your browser rather than on a server, and its split view is still the best way to see exactly what a setting does to one image. If you are preparing a single hero image for a website and want to judge every setting by eye, use Squoosh.
The job this page is built for is different, and it is the more common one: a folder of product photos for an online shop, twenty screenshots for a report, a set of photos an upload form wants under 200 KB each. That calls for one decision applied to everything, and a way to get the whole set back at once.
| This tool | Squoosh | |
|---|---|---|
| Where it runs | Your browser | Your browser |
| Uploads your images | No | No |
| Images at a time | As many as you add | One, with a side by side view |
| Compress to a file size | Yes | No, you adjust by eye |
| Maximum width for the whole batch | Yes | Resize per image |
| Download | One ZIP for the batch | Each image on its own |
| Codec options | A few sensible ones | Extensive, per codec |
Squoosh details are from its public project page, read on 11 September 2026, and from how its web app works: one image opened at a time in its editor.
Hitting a size limit across a whole batch
To a file size is the part Squoosh does not have. Enter the limit and each image is encoded at the highest quality that still fits under it, so every file in the batch passes the same check without you tuning them one by one. It works with JPEG, WebP and AVIF. PNG has no quality dial to turn, so for PNG the tool uses Smart instead.
If the images are much larger than they will ever be shown, set a maximum width as well. A 4,000 pixel phone photo shown 1,200 pixels wide on a shop page carries more than ten times the pixels it needs, and shrinking it first saves more than any quality setting.
When to reach for Squoosh instead
- One important image. The split view lets you judge the trade between size and quality far more precisely.
- Codec tuning. Squoosh exposes options for each format that this tool deliberately keeps out of the way.
- Learning. Watching the file size change as you drag a slider is the fastest way to understand what each format does.
For everything else, especially anything with more than a handful of images, it is quicker to set the rule once and let the whole folder follow it.
Common questions
Is this Squoosh?
No, and it has no connection to Squoosh, which is an open source project from Google Chrome Labs. This is a separate image compressor that also works inside your browser.
Does Squoosh upload my images?
No. Squoosh's own project page says it does not send your image to a server and that all compression happens locally. That is the same principle this tool follows, and it is to Squoosh's credit. The difference between the two is not privacy, it is workflow.
So what is the difference?
Squoosh is built for tuning one image by eye, with a split view to compare the original and the result and a deep set of options for every codec. This tool is built for getting a whole folder done: many images at once, one setting for all of them, a target file size, and a single ZIP at the end.
Can I compress every image to under a set size?
Yes. Choose To a file size and enter the limit. Each image is encoded at the highest quality that fits. It works for JPEG, WebP and AVIF; PNG has no quality setting to lower, so a PNG target falls back to Smart.
Which format should I choose?
WebP for most things: every current browser shows it, it is smaller than JPEG, and it keeps transparency. AVIF is smaller still but slow to encode, especially on phones. JPEG when the image is going somewhere that only accepts JPEG, such as many upload forms.
