Optimage vs Squoosh — Which Free Image Optimizer Should You Use in 2026?
Squoosh excels at single-image fine-tuning with advanced codec sliders. Optimage wins for bulk processing, client galleries, and a full suite of editing tools.
Squoosh is Google's browser-based image optimizer and one of the best free tools available for fine-tuning a single image — it offers live side-by-side quality comparisons and codec-level controls that no other free tool matches. Optimage is the better choice the moment you need to process more than one image at a time, deliver files to clients, or use tools beyond compression such as resize, crop, watermark, or rotate. The two tools are complementary rather than competing.
What Squoosh Does Exceptionally Well
Squoosh deserves its reputation. It is a Progressive Web App built by the Google Chrome team that runs entirely in your browser — no server upload, no sign-in, no file size limits imposed by a server. You drop one image and get a live split-view where you can scrub through codec settings (MozJPEG, WebP, AVIF, OxiPNG, and more) and see exactly how each quality setting affects the output in real time.
If you are a front-end developer optimising a hero image for a landing page and you need to squeeze every byte while keeping the result visually perfect, Squoosh is a genuinely excellent tool. That use case is where it shines.
Where Squoosh Hits Its Limits
Squoosh processes one image at a time. There is no batch mode, no queue, and no way to apply the same settings across a folder. There are no client galleries, no resize or crop controls, no watermark, no metadata stripping toggle. It is a compression and conversion tool — a very good one — and nothing more.
For photographers delivering 300 images from a shoot, e-commerce teams optimising 500 product photos, or marketers building asset libraries, Squoosh is impractical. The one-by-one workflow simply does not scale.

| Resize tool | Yes | Basic (pre-encode resize) |
| Crop tool | Yes | No |
| Watermark | Yes | No |

Format Support: Where They Are Even
Both tools support the formats that matter in 2026 — AVIF, WebP, JPEG, and PNG. This is one area where Squoosh and Optimage are genuinely matched. Squoosh's codec library is arguably broader (it exposes OxiPNG, JPEG XL experiments, and raw quality curves), while Optimage focuses on the four production-ready formats with sensible defaults rather than low-level controls.
For most workflows the practical output is the same: well-compressed AVIF or WebP files ready to drop into a <picture> element. Optimage's convert tool applies format conversion across your entire batch in one pass.
The Gallery Difference
Squoosh has no sharing or delivery layer. Once you compress an image you download it to your device and share it however you normally would.
Optimage includes client galleries: a photographer or designer uploads a set of images, sets a PIN, chooses whether clients can download full-resolution or web-resolution files, and shares a link. Clients browse the gallery, mark favourites, and download — no app installation required. This is a feature category that Squoosh does not attempt to address.
Workflow Fit
Squoosh is right for you if:
- You are optimising one or two hero images for a specific page and want pixel-level control over the output.
- You prefer to keep your images local (Squoosh processes client-side without uploading to a server).
- You want to experiment with bleeding-edge codecs.
Optimage is right for you if:
- You process images in batches — product photos, event photography, social media assets.
- You need to resize, crop, rotate, watermark, or strip metadata alongside compression.
- You deliver images to clients and want a professional, branded gallery link instead of a raw download.
- You want consistent quality defaults without tweaking codec sliders for every file.
Verdict
Squoosh is among the best single-image optimisation tools available, full stop. If fine-grained codec control for a single file is your priority, use it. If your workflow involves more than one image at a time, or if you need any tooling beyond compression, Optimage fills the gaps Squoosh leaves open — at no cost and without a sign-in.
Frequently Asked Questions
Is Squoosh better than TinyPNG? For single-image quality and codec variety, yes — Squoosh gives you live previews and more format options including AVIF. TinyPNG is faster for quick batch jobs up to 20 files with no configuration. Both are free.
Can Squoosh handle multiple files? No. Squoosh processes one image at a time. There is no batch mode or queue. For bulk compression, Optimage or TinyPNG are better suited.
What is Squoosh? Squoosh is a free browser-based image optimiser built by the Google Chrome team. It runs entirely in the browser (no server upload) and lets you compare compression codecs side by side with real-time quality previews.
Does Squoosh support AVIF? Yes. Squoosh supports AVIF encoding via its browser-side codec library. Encoding large images to AVIF can be slow in the browser, but the output quality is excellent.
What is the best alternative to Squoosh for bulk image processing? Optimage supports up to 50 files per batch with WebP and AVIF output, plus resize, crop, watermark, and client gallery features — all free, no sign-up required.
