Google's Squoosh is a genuinely impressive image compression tool. It runs entirely in your browser using WebAssembly, supports advanced codecs like AVIF and WebP, and gives you a real-time side-by-side quality preview. For a single image, it's hard to beat.
But Squoosh has real limitations that push many users to look for alternatives. It processes one image at a time, has no batch mode, and its toolset ends at compression — there's no resizing, format conversion, background removal, or watermarking. If you need more than one thing done, you're opening multiple tabs and repeating yourself for every file.
This guide covers five free alternatives that fill those gaps — including tools that go far beyond what Squoosh offers, while keeping your images off of remote servers.
What Makes a Good Squoosh Alternative?
Not every image tool that calls itself "browser-based" actually keeps your data local. Here's what to look for when evaluating a Squoosh replacement:
- True browser-based processing — images should be processed using JavaScript or WebAssembly in your tab, not uploaded to a cloud server. Open DevTools and watch the Network tab to verify.
- Batch support — processing 20 images one at a time defeats the purpose. A good alternative lets you drop a folder or select multiple files.
- Broader toolset — compression is one task. Resizing, format conversion, HEIC support, background removal, and PDF tools mean fewer apps open.
- No signup required — account walls slow you down. The best tools work immediately on arrival.
- No file limits — free tiers that cap you at 20 images per month are not truly free for regular use.
1. QuickImg — Best All-in-One Alternative
QuickImg is the most comprehensive browser-based image toolkit available in 2026. Unlike Squoosh, which focuses entirely on compression, QuickImg offers 14 tools covering every common image task — all processed locally in your browser using the Canvas API and JavaScript. Nothing you drop into QuickImg ever leaves your device.
Key capabilities include:
- Compress JPG, PNG, WebP, and GIF — with batch support for multiple files at once
- Resize images to exact pixel dimensions or by percentage
- Convert between formats including WebP, PNG, JPG, and more
- Remove image backgrounds using on-device AI
- Convert HEIC/HEIF files from iPhone to JPG or PNG
- Convert PDFs to images and images to PDF
- Add watermarks, crop, rotate, and flip images
- Generate favicons and code screenshots
It's 100% free with no account required. For anyone who was using Squoosh just for compression but needed other tools from separate sites, QuickImg consolidates everything into one place without the privacy trade-off of cloud tools.
Compress images in your browser — no upload, no limits, no account
Try QuickImg Compression →2. TinyPNG
TinyPNG is one of the most recognized names in image compression, and for PNG and JPG files it delivers reliable results with a clean drag-and-drop interface. The compression quality is excellent, and it now supports WebP output as well.
The trade-off is that TinyPNG is fully cloud-based — your images are uploaded to their servers for processing. The free tier limits you to 20 files per session, and images larger than 5 MB on the free plan are rejected. If privacy is a concern or you regularly work with batches larger than 20 files, you'll hit walls quickly. A paid API is available for heavier usage.
3. Squoosh (the original)
It would be unfair to list alternatives without acknowledging where Squoosh excels. For a single image where you want granular control — choosing between MozJPEG, OxiPNG, AVIF, WebP, or even JPEG XL — Squoosh's codec selector and real-time quality slider are unmatched. You can see the exact byte size at every quality level before committing.
But that precision is also Squoosh's ceiling. There is no batch mode, no resize tool, no conversion pipeline, and no way to process 50 product photos quickly. If you find yourself returning to it for one image at a time while using three other tools for everything else, it may be time to consolidate.
4. iLoveIMG
iLoveIMG is a comprehensive image toolkit covering compression, resizing, cropping, format conversion, and more through a clean web interface. The breadth of tools rivals QuickImg, and the UI is straightforward for non-technical users.
The major downside is that all processing happens on iLoveIMG's cloud servers — your images are uploaded, processed remotely, and then a download link is returned. There are daily processing limits on the free plan, and the terms of service grant them certain rights over uploaded content. For sensitive or confidential images, this is a significant consideration.
5. Picflow
Picflow is a modern browser-based image converter with a clean, fast interface and good WebP conversion support. It processes images locally in the browser, which is a genuine privacy advantage over cloud tools. The tool is fast and works well for straightforward conversion tasks.
Where Picflow falls short relative to QuickImg is breadth — it focuses primarily on conversion and basic compression, without the resizing, background removal, HEIC support, PDF tools, or watermarking that a complete image workflow requires. It's a solid single-purpose tool but not a full Squoosh replacement for users who need more.
Quick Comparison
| Tool | Browser-Based | Batch Support | Free Limits |
|---|---|---|---|
| QuickImg | Yes (Canvas API) | Yes | Unlimited |
| Squoosh | Yes (WebAssembly) | No | 1 image at a time |
| TinyPNG | No (cloud) | Yes (up to 20) | 20 files / 5 MB each |
| iLoveIMG | No (cloud) | Yes | Daily limits apply |
| Picflow | Yes | Limited | Mostly free |
Conclusion
Squoosh set a high bar for browser-based image tools, but its narrow focus on single-image compression has left a wide gap for tools that handle the full range of image tasks people actually need. For users who want compression, conversion, resizing, background removal, and more — all in one place, all processed locally with no uploads — QuickImg is the most complete free alternative in 2026.
If you only ever need to compress one image at a time with maximum codec control, Squoosh remains excellent at that specific task. But for any workflow involving multiple images, multiple operations, or privacy-sensitive files, QuickImg covers everything without limits or cloud uploads.
