Features and specs

What each product offers, as listed by its team.

Sunasty 10 features
E
Ember-cli 5 features
  • 100% in-browser processing
    Every tool runs locally via WebAssembly (FFmpeg, qpdf, MozJPEG/OxiPNG/WebP/AVIF codecs). Your files never reach a server: there is nothing to upload, leak or delete.
  • 130+ tools in one place
    PDF, images, video, audio, converters, developer utilities, date tools, calculators and QR codes, all under one roof with a consistent interface.
  • No account, no quotas
    No sign-up, no daily limits, no file size tiers, no premium plan.
  • Works offline
    Once a tool's page has loaded, it keeps working with the connection cut. Installable as a PWA.
  • Full PDF suite
    Merge, split, compress (lossless or strong), organize, rotate, sign, protect, unlock with a known password, watermark, page numbers, OCR and more.
  • Smart image compression
    Pick a quality or a target size in KB, convert between JPEG, PNG, WebP and AVIF, process whole batches at once.
  • Video & audio toolbox
    Compress and convert video, trim, mute, extract audio to MP3/WAV/AAC/OGG, GIF in both directions, plus local screen, webcam and voice recorders.
  • Verifiable privacy
    Open DevTools' network tab while using any tool: no request ever carries your file. Re-encoding strips EXIF metadata (including GPS).
  • 28 languages
    Fully localized, including right-to-left Arabic. Guides even show screenshots of the tools in your own language.
  • Honest by design
    Illustrated guides, transparent competitor comparisons, and clear notes about what a browser cannot do faithfully.
  • Convention over Configuration
    Ember-cli enforces strong conventions for file structure, naming, and project organization, which reduces decision fatigue and makes it easier for developers to jump between different Ember projects with minimal onboarding time.
  • Built-in Tooling
    Comes with a robust set of built-in tools including a development server, testing framework integration (QUnit), asset compilation, and live reload, reducing the need to manually configure and integrate third-party build tools.
  • Addon Ecosystem
    Ember-cli supports a rich ecosystem of addons that can be easily installed and integrated into projects, allowing developers to extend functionality without reinventing the wheel for common features.
  • Blueprints and Generators
    Provides powerful generator commands (blueprints) that scaffold components, routes, models, and other application pieces quickly, speeding up development and ensuring consistency across the codebase.
  • Stable Long-term Support
    Ember-cli follows Ember's release cycle with clear LTS (Long Term Support) versions, providing stability and predictability for teams maintaining large applications over time.

Possible disadvantages

  • Steep Learning Curve
    The strict conventions and unique architecture of Ember-cli can be difficult for newcomers to learn, especially those coming from more flexible frameworks or with no prior Ember experience.
  • Smaller Community Compared to Alternatives
    Compared to tools like Vite, Webpack, or CRA used with React/Vue, Ember-cli has a smaller community and ecosystem, which can mean fewer third-party resources, tutorials, and community-driven troubleshooting.
  • Build Performance
    For large applications, Ember-cli's build process can become slow, and while improvements have been made with embroider, some developers still report slower build times compared to more modern bundlers.
  • Rigid Structure
    The opinionated nature of Ember-cli, while helpful for consistency, can feel restrictive for developers who prefer more flexibility in structuring their applications or adopting non-standard patterns.
  • Migration Complexity
    Upgrading between major Ember-cli versions or migrating to newer build systems like Embroider can be complex and time-consuming, particularly for older or heavily customized applications.

Questions & Answers

As answered by people managing Sunasty and Ember-cli.

Which are the primary technologies used for building your product?

Sunasty's answer

The site is statically generated with Astro and TypeScript, with lightweight Preact islands for interactivity. The heavy lifting runs client-side in Web Workers through WebAssembly builds of proven engines: FFmpeg for video and audio, qpdf and pdf-lib for PDF, the Squoosh codecs (MozJPEG, OxiPNG, WebP, AVIF) for images, and Tesseract for OCR. There is no application backend at all: the server only delivers static files.

What makes your product unique?

Sunasty's answer

The privacy is structural, not a policy promise: every tool runs entirely in your browser through WebAssembly, so your files never leave your device. You can verify it yourself by opening the DevTools network tab while using any tool: no request carries your file, and everything keeps working offline once the page has loaded. Combined with 140+ tools, no account, no quotas and 28 languages, that architecture is the product.

Why should a person choose your product over its competitors?

Sunasty's answer

Most popular alternatives (iLovePDF, Smallpdf, CloudConvert, TinyPNG) process files on their servers and monetize through limits: daily quotas, file size caps, subscriptions. With Sunasty there is no upload wait, no copy of your document on someone else's machine, and no counter to unlock, because the work happens on your own hardware. And when a competitor genuinely is the better choice (for example server-side conversion of PDF to editable Word, which a browser cannot do faithfully), our comparison pages say so.

How would you describe the primary audience of your product?

Sunasty's answer

Anyone who handles files day to day: people compressing a PDF to fit an application portal or an email cap, gamers and creators trimming and shrinking clips for Discord, anyone blurring a name on a screenshot before sharing it, developers formatting JSON or testing regexes, and privacy-conscious users working with contracts, IDs or anything confidential that should never transit through a third-party server.

What's the story behind your product?

Sunasty's answer

Sunasty is built by a solo developer in France. The trigger was a familiar frustration: every "free" online tool for a 30-second file task wanted an upload to an unknown server, an account, or a subscription to lift an artificial limit. Modern browsers can do that work themselves thanks to WebAssembly, so Sunasty was built the other way around: the file never leaves your device, by architecture. The amber cat in the logo is the developer's actual cat.

Who are some of the biggest customers of your product?

Sunasty's answer

Sunasty is a free consumer tool, so there are no enterprise contracts to name, and since there are no accounts and files never reach us, we genuinely cannot tell who uses it. It is used by individuals worldwide in 28 languages, which is exactly how a privacy tool should work.
