Vizua vs Squoosh: Controls, Batch Workflow, and Privacy
Vizua and Squoosh both transform the selected image in the browser, but they organize the work differently. This comparison was reviewed on July 17, 2026 and separates observed product behavior from quality claims that depend on the source and settings.
What Each Tool Does
Squoosh is an open-source image-compression web app from Google Chrome Labs. Its current interface takes one active image, lets you choose an available output codec and preprocessing options, and provides a split comparison with file-size feedback. Treat the live codec menu as authoritative because experimental formats can be added or removed.
Vizua has 93 distinct tools plus three compatibility routes. Compression is one part of a broader suite that covers format conversion, resizing, cropping, effects, text overlays, social presets, selected batch workflows, background removal, and OCR text extraction.
Compression: Head to Head
Output quality and size depend on the image, encoder build, parameters, dimensions, color handling, and metadata. The table compares exposed workflows, not a universal compression winner:
| Aspect | Vizua | Squoosh |
|---|---|---|
| JPEG compression | Yes — quality slider with preview | Yes — advanced encoder with granular controls |
| PNG compression | Yes — optimized lossless | Yes — advanced lossless optimizer |
| WebP compression | Yes — adjustable lossy quality | Yes — controls depend on the current encoder |
| AVIF support | Yes — convert to AVIF | Yes — full AVIF encoding |
| Experimental codecs | No JPEG XL tool | Check the current codec menu |
| Side-by-side preview | Before/after with file size | Slider comparison with pixel-level detail |
| Codec parameter control | Quality slider (simplified) | Full codec-level parameters |
Squoosh exposes more encoder-specific and preprocessing controls. Vizua uses a simpler workflow in which the available controls depend on the dedicated tool. More controls can help an experienced user explore a target, but they do not automatically produce a smaller or better-looking file. Test representative images with matched output requirements.

Batch Processing
This is where the tools diverge most sharply.
Squoosh used one active image in the reviewed web interface. That is convenient for close inspection of a single asset but is not the same as a browser queue that applies one configuration to several selected files. Historical issue or CLI status is not needed to establish the current interface behavior.
Vizua supports multiple selected files in tools including JPEG compression, PNG compression, WebP compression, and format conversion. Output and ZIP options vary by tool, while practical capacity depends on file dimensions, browser memory, and the device. Test a representative batch before committing a large job.
Beyond Compression
Squoosh is a compression tool. Vizua is a full image editing platform. Here is the scope difference:
| Feature | Vizua | Squoosh |
|---|---|---|
| Compression | Dedicated JPEG, PNG, and WebP tools | Codecs exposed by the current build |
| Resize | Yes (with presets) | Yes (basic) |
| Crop | Yes | No |
| Format conversion | Dedicated format-pair and batch tools | Between codecs in the current menu |
| Image effects | Dedicated effect and filter tools | No comparable effect suite |
| Text on image | Yes | No |
| Background removal | Yes (AI-powered) | No |
| OCR text extraction | Yes | No |
| Social media presets | Instagram, Facebook, X, LinkedIn, YouTube | No |
| EXIF viewer | Yes | No |
| Batch processing | Yes (select tools) | No |
| Product scope | 93 distinct tools plus three compatibility routes | One focused compression web app |
Squoosh is not trying to be a full editor — it does one thing and does it well. Vizua is built for users who need compression as part of a broader image workflow and want everything in one place. For more on how format choice affects file size and quality, see WebP vs AVIF.
Privacy and Architecture
Both tools process the selected image in the browser. Vizua does not send the selected file to our image-processing servers; the page can still use the network for required code, site features, analytics, and error monitoring.
Squoosh states that images do not leave the device for compression. Its public repository also discloses Google Analytics collection of basic visitor data, before-and-after image sizes, and some PWA details. Local image transformation therefore should not be confused with an offline page or a promise that no telemetry exists.
Avoid treating browser-side processing as automatic approval for sensitive client, medical, legal, or personal material. Device security, page code, extensions, telemetry, output metadata, and organizational policy still matter.

UX and Workflow
Squoosh uses a focused comparison workspace with an active image, preprocessing controls, codec choices, settings, and a split preview. The exact controls and layout depend on the current build and selected codec.
Vizua organizes 93 tools by category: compress, convert, edit, effects, AI tools, social media. Each tool has its own dedicated page. The trade-off is that you navigate between pages rather than having everything in a single view. The upside is that each tool is purpose-built for its task and not cluttered by unrelated controls.
The Bottom Line
Choose Squoosh when you want a focused single-image comparison and the current build exposes the codec controls you need.
Choose Vizua when you need a supported batch workflow or editing tasks beyond compression. Its 93 distinct tools cover work from JPEG compression to background removal and social-media resizing, with tool-specific inputs and limits.
Both tools are free. The choice comes down to whether you need a scalpel (Squoosh) or a full toolbox (Vizua).
Frequently Asked Questions
Is Squoosh still available in 2026?
Yes. The web app at squoosh.app was reachable when this comparison was reviewed on July 17, 2026, and its source repository remained public. Availability does not prove a particular maintenance cadence. Check the current app, repository activity, and open issues if long-term support matters to a production workflow.
Which tool has better compression quality?
Neither tool wins every image. Squoosh exposes more encoder and preprocessing controls in a focused comparison interface; Vizua offers simpler controls across dedicated tools. Compare the same source, dimensions, codec, metadata policy, and quality target, then inspect both visual output and bytes instead of comparing slider numbers.
Can Vizua create AVIF files like Squoosh?
Yes. Vizua creates AVIF output through Convert to AVIF, while the reviewed Squoosh build also exposed AVIF encoding. Both perform the selected image transformation in the browser. Codec lists can change, so verify the current interface if a particular encoder or experimental format is required.
Does Squoosh support batch processing?
The Squoosh web interface reviewed on July 17, 2026 used a single active-image workflow rather than a multi-file batch queue. Vizua supports multiple files in selected compression and conversion tools, subject to tool, browser-memory, and device limits. Verify both current interfaces before building a recurring production process around that distinction.
Are both tools free to use?
Both web apps were usable without payment or an account when reviewed. Squoosh states that image compression is local, while its repository discloses analytics including basic visitor data and before-and-after sizes. Vizua processes selected files in the browser without sending them to its image-processing server; both pages still make ordinary network requests.
