Sunasty is a suite of 130+ free utilities for everyday file tasks: PDF (merge, split, compress, sign, unlock), images (compress, resize, crop, redact, HEIC to JPG), video and audio (compress, convert, trim, extract audio, screen recording), plus developer, date and calculator tools.

The difference is structural: every tool runs entirely in your browser using WebAssembly (FFmpeg, modern image codecs, qpdf). Files are never uploaded to a server, which you can verify in your browser's network tab. Tools keep working offline once loaded. No account, no file size tiers, no daily quotas. Available in 28 languages.

Sunasty features and specs

  • 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.

Thread Notes features and specs

  • Simple and Focused
    Thread Notes offers a clean, minimalist interface designed specifically for note-taking and organizing thoughts in threaded conversations, making it easy to use without a steep learning curve.
  • Threaded Organization
    The app organizes notes in a threaded format, which helps users keep related ideas and thoughts connected and structured in a logical, hierarchical manner.
  • Lightweight Tool
    Thread Notes is a lightweight application that doesn't require heavy system resources or complex setup, making it accessible and quick to start using.
  • Ideal for Brainstorming
    The threaded structure is well-suited for brainstorming sessions, allowing users to branch off ideas and explore different trains of thought while maintaining context.
  • Web-Based Accessibility
    Being a web-based tool, Thread Notes can be accessed from any device with a browser, offering flexibility and convenience without needing to install dedicated software.

Possible disadvantages of Thread Notes

  • Limited Brand Recognition
    Thread Notes is a relatively niche and lesser-known tool compared to established note-taking apps like Notion, Evernote, or Obsidian, which means fewer community resources and integrations.
  • Limited Feature Set
    Compared to more full-featured note-taking platforms, Thread Notes may lack advanced features such as rich media embedding, extensive formatting options, or collaboration tools.
  • Uncertain Long-Term Viability
    As a smaller, independent product, there may be concerns about long-term maintenance, updates, and whether the service will continue to be supported over time.
  • Lack of Integrations
    Thread Notes may not offer robust integrations with other productivity tools, calendars, or project management platforms that many users rely on in their workflows.
  • Limited Offline Support
    As a web-based tool, Thread Notes may have limited or no offline functionality, which can be a drawback for users who need to access their notes without an internet connection.

Questions & Answers

As answered by people managing Sunasty and Thread Notes.

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.
