What each product offers, as listed by its team.

abox.tools 11 features
StackMail 5 features
  • Everything runs in your browser
    No file is ever uploaded. Each tool does its work on your own machine — there is no server to send it to.
  • Tools available
    24, across six categories: images & video (14), GIF & animation (3), documents & PDF (3), audio (2), codes & data (1), text & code (1).
  • Works offline
    Every tool registers a service worker, so it keeps working after the first visit with no connection at all.
  • No account, no signup
    Nothing to register, nothing to install. Open a tool and use it.
  • Price
    Free. No paid tier, no usage quota, no trial.
  • Verifiable, not just promised
    Every page ships a Content-Security-Policy of default-src 'none' whose connect-src omits 'self', so the page cannot send your file anywhere even in principle.
  • No Watermarks
    Nothing is stamped onto the files the tools produce.
  • Languages
    11 — English, German, Spanish, French, Hindi, Italian, Japanese, Korean, Dutch, Portuguese (BR), Simplified Chinese.
  • File size limit
    et by your own device's memory, not by a server quota or an upload cap.
  • Source published
    The generator and every tool's source are public, and the built site is committed, so you can diff what's served against a build of the sources.

  • Custom Domain Support
    Users can easily set up email addresses with their own custom domain names, enhancing brand professionalism and consistency.

Possible disadvantages

  • Limited Brand Recognition
    As a newer or lesser-known provider compared to Google Workspace or Microsoft 365, StackMail may lack the trust and reputation that larger providers have established.
  • Fewer Third-Party Integrations
    Compared to major email service providers, StackMail may offer fewer integrations with third-party apps and services, limiting its versatility for some businesses.
  • Limited Advanced Features
    It may not offer the same breadth of advanced productivity and collaboration tools that come bundled with larger platforms like Microsoft 365 or Google Workspace.
  • Smaller User Community
    Due to a smaller user base, there may be fewer community resources, third-party tutorials, or troubleshooting forums available online.
  • Uncertain Long-Term Support
    As a smaller company, there might be concerns regarding the long-term viability, updates, and continued support of the service compared to more established providers.

Questions & Answers

As answered by people managing abox.tools and StackMail.

Who are some of the biggest customers of your product?

abox.tools's answer

None — abox.tools is free and has no accounts, no signup and no server, so there are no customer records.

What makes your product unique?

abox.tools's answer

All tools do their work entirely inside your browser. The claim isn't "we promise not to look at your files" — it's that there is no code path that could send them anywhere. Every tool page ships a Content-Security-Policy of default-src 'none', and its connect-src does not include 'self', so the page cannot open a connection back to its own origin even if code were added that tried. The site is open source and the built output is committed to a branch, so anyone can diff what's actually served against what a build of the sources produces.

Why should a person choose your product over its competitors?

abox.tools's answer

The usual online converters — CloudConvert, iLovePDF, Smallpdf, the various online EXIF removers — upload your file to a server, process it there and hand back a download link. That buys you a queue, a file-size cap, usually an account, and a copy of your file on somebody else's disk.

abox.tools does the same work on your own machine instead: no upload, no account, no file-size limit, and it keeps working offline after the first visit because every tool registers a service worker. It's free, and there's nothing to install.

How would you describe the primary audience of your product?

abox.tools's answer

People who need a one-off file job done and would rather not hand the file over: converting iPhone HEIC photos, stripping GPS and EXIF data before posting a picture, trimming a video or an audio clip, merging PDFs, making a favicon or a QR code.

Two groups over-index. Privacy-conscious users, who want the guarantee rather than the promise. And developers and IT staff, who can read the source and check the claim rather than take it on faith. It's also used by people handling material they're not permitted to upload at all — client documents, medical scans, anything under an NDA. The site is available in 11 languages.

What's the story behind your product?

abox.tools's answer

It started from a small observation: "free online converter" almost always means "upload your file to our server." Modern browsers can do nearly all of that work themselves — WebCodecs, Canvas, Web Audio, WebAssembly — so for most of these jobs the upload is a business decision rather than a technical necessity.

So it was built as a static site with no backend at all, which makes the privacy claim structural instead of a policy someone has to trust. It's deliberately kept small and readable: no dependencies, no lockfile, no JavaScript build step, so the code in the repository is byte-for-byte what the browser runs.

Which are the primary technologies used for building your product?

abox.tools's answer

  • Static site generated by a Python 3.11+ script using only the standard library — no runtime, no database, no backend of any kind.
  • Vanilla JavaScript ES modules. No framework, no dependencies, no lockfile, no bundler; tools//src/ is byte-for-byte what the browser executes.
  • Browser APIs do the actual work: WebCodecs (VideoEncoder/VideoDecoder/AudioEncoder), Canvas and createImageBitmap, Web Audio, ImageDecoder, and Service Workers for offline use.
  • One vendored WebAssembly engine, libheif, for HEIC decoding — it runs on the visitor's machine like everything else.
  • Hand-written format code where the browser offers no API: GIF LZW encoder and decoder, MP4 reader and writer, PDF reader and writer, EXIF/TIFF parser, QR and barcode generation.
  • Served as static files from GitHub Pages, with DNS at Cloudflare.
