Home / Blog / Image Tools ImageGates vs Squoosh — Honest Comparison (2026)
By Abdulkeni Abdelwahid Updated 2026 10 min Try it now: Try the free compressor
Open tool Squoosh is Google's browser-only image compressor — genuinely great, privacy-friendly, and beloved by developers who want to experiment with codecs. ImageGates competes in the same on-device lane but is built for a different job. Both are free and both process locally, so this comparison is about workflow fit rather than trust — here's where each one actually wins, with specifics rather than vague marketing claims.
The 30-second summary
Pick Squoosh for one-file-at-a-time, side-by-side codec experimentation — MozJPEG vs WebP vs AVIF vs JXL — with fine-grained encoder controls. Pick ImageGates for batch work, KB-target compression, purpose-built pages for specific specs (visa photos, A4 print, Instagram), and anything beyond the codec-tinkering use case.

| Exact KB target | Yes — 12 KB-target tools | No — manual slider only |
| Purpose-built pages | Yes — Instagram, A4, 2×2, YouTube, LinkedIn… | No — one generic UI |
| Passport / visa photo tools | 193 countries | No |
| Actively maintained | Yes, weekly | Yes, but slower cadence |
Why developers love Squoosh
Squoosh's split-view preview is best-in-class. You drop one image, pick a codec on the right pane, and drag a slider to see visual artifacts appear in real time. If your job is "figure out how low can I push the quality on this hero image before it looks bad," Squoosh is the right tool. It also supports experimental codecs (AVIF, JXL) that ImageGates doesn't ship yet, because browser support outside Squoosh's own polyfill is still spotty for most visitors.
Where Squoosh falls down
Two hard limits stand out for everyday, non-developer workflows:
- One file at a time. There's no batch upload. If you have 20 product photos to compress for a Shopify store, that's 20 open-tab-drag-save cycles.
- No KB targeting. Every form that says "upload a photo under 100 KB" turns into a slider-and-check loop, re-exporting until the number happens to line up. ImageGates hits the target directly via a dedicated page.
Both are conscious design choices — Squoosh is a codec playground, not a production tool. But they're the reason most people who try Squoosh once for a real task end up using something else for their actual workflow.
A practical test: compressing 15 product photos to under 150 KB each
On Squoosh, this means opening each image individually, dragging the quality slider, checking the resulting KB counter in the corner, re-adjusting, and repeating — roughly 15 separate multi-step sessions. On ImageGates, you'd open the 150 KB compressor page, drop all 15 files at once, and download a single zip with every file already under the target. The end quality is comparable; the time spent is not.
Where ImageGates wins
- Batch of 20+ files. Drop them all; get a zip back.
- KB target for a form. Visa, exam, job portal — pick the size, done.
- Purpose-built pages. "Resize for Instagram" is one URL; the dimensions are baked in, no manual entry.
- Passport / visa specs. Country-by-country, with a free compliance checker.
- Non-developer UX. No codec choices, no jargon — just a slider and a download button.
Where Squoosh wins
- AVIF and JPEG-XL. If you need experimental codecs today, Squoosh is one of the only free browser tools that ships them polyfilled.
- Codec comparison. The split-view slider is unmatched for A/B'ing encoders side by side.
- Encoder controls. Chroma subsampling, filter passes, effort levels — Squoosh exposes them all for fine-tuning.
When Squoosh is genuinely the better fit for you
If you're a developer optimizing a hero image or icon set for a production website and you care about squeezing out the last few percent using AVIF or JPEG-XL with exact encoder parameters, Squoosh remains the better tool for that specific job — full stop. ImageGates isn't trying to replace that workflow; it's built for the much larger set of people who just need a photo compressed, resized, or made passport-compliant without learning what chroma subsampling means.
The verdict
Squoosh is one of the best free codec playgrounds available. ImageGates is built to be the most convenient free image-utility site for everyday tasks. They're both privacy-safe browser-only tools, so pick by workflow, not trust: use Squoosh when you want to think about the encoder, use ImageGates when you want to think about the result.
History and origin of each project
Squoosh was built by the Google Chrome team as a demonstration of what WebAssembly-compiled codecs could do directly in a browser, and it remains a reference implementation for the industry — many other in-browser compressors, ImageGates included, exist because Squoosh proved the concept was viable without a server round trip. ImageGates was built specifically to solve everyday, non-developer image tasks — resizing for a platform, hitting a KB limit for a form, prepping a passport photo — rather than to showcase codec technology, which explains why the two tools diverge so much in UI philosophy despite sharing the same underlying browser-based approach.
Output quality at the same target size
Because both tools ultimately rely on similar underlying encoders (MozJPEG for JPEG output, for example), a compressed file from either tool at the same file size looks nearly identical to the eye. The practical difference isn't the encoder quality — it's how quickly and reliably you can hit your intended size and dimensions. If you compress the same photo to 150 KB on both tools, expect comparable sharpness and comparable artifacting around fine detail; the meaningful gap is entirely in workflow speed, not pixel quality.
Handling edge cases: transparency and animation
Squoosh supports transparent PNG and WebP encoding with fine control over the alpha channel compression, useful for developers optimizing icon sets or sprite sheets. ImageGates preserves transparency in PNG output as well, though it doesn't expose separate alpha-channel quality controls, since the target audience is generally optimizing a whole image rather than tuning transparency compression specifically. Neither tool handles animated formats (GIF, animated WebP) — both are built for static images.
Choosing between them for a specific job
| Job | Better tool | Why |
|---|
| Compress 30 product photos for a store | ImageGates | Batch upload, no per-file re-export |
| Fine-tune a hero image with AVIF | Squoosh | Codec choice and encoder controls |
| Hit an exact 100 KB visa photo limit | ImageGates | Dedicated KB-target page |
| Compare MozJPEG vs WebP visually side by side | Squoosh | Split-view slider built for exactly this |
| Prep a passport photo to spec | ImageGates | Country-specific dimension and background tools |
Long-term maintenance and reliability
Squoosh's original core team has moved on to other projects at Google, so while the tool remains functional and hosted, update frequency has slowed noticeably compared to its early years. ImageGates is actively maintained with weekly updates, meaning new tools, edge-case fixes, and country-specific requirement updates ship continuously — important for something like passport photo rules, which occasionally change and need to be reflected quickly.
