About StackMail and Gottrix.app

In their own words, as submitted to SaaSHub.

No description of StackMail yet.

Almost every "free" online file converter works the same way: you upload your file to a server, it gets processed there, and you download the result. gottrix works differently. Every single conversion, from compressing a PDF to trimming an MP3 to converting a HEIC photo, runs entirely inside your...

Questions & Answers

As answered by people managing StackMail and Gottrix.app.

Which are the primary technologies used for building your product?

Gottrix.app's answer:

Astro and TypeScript for the site itself, Tailwind CSS for styling, and WebAssembly for the actual conversion engines (ffmpeg.wasm for audio/video, pdf.js and pdf-lib for PDF, libheif and Squoosh for images), all running inside sandboxed Web Workers with zero network access.

How would you describe the primary audience of your product?

Gottrix.app's answer:

Anyone handling files they'd rather not hand to a third-party server: freelancers and professionals working with contracts, invoices or client documents, students and privacy-conscious individuals doing everyday conversions, and international users thanks to 25+ language support. Also a good fit for regulated or confidential business contexts where uploading a file anywhere isn't an option.

What's the story behind your product?

Gottrix.app's answer:

gottrix started from a simple frustration: nearly every "free" online file converter requires uploading your document to someone else's server, even for something as routine as compressing a PDF or converting a photo. gottrix was built to remove that requirement entirely. Everything runs in the browser via WebAssembly, so the file never leaves the device in the first place.

What makes your product unique?

Gottrix.app's answer:

Every conversion runs 100% client-side in WebAssembly - files never touch a server, provably so (you can verify it yourself in DevTools' Network panel, or just try it in airplane mode after the first visit). Most converters ask you to trust a privacy policy; gottrix lets you check. On top of that: 500+ tools across PDF, image, audio, video, data and 3D formats in one place, no account, no signup, available in 25+ languages.

Why should a person choose your product over its competitors?

Gottrix.app's answer:

Competitors like Smallpdf, iLovePDF, Convertio and CloudConvert upload your file to their servers to process it - fine for a random image, risky for a contract, medical record, or anything confidential. gottrix never uploads anything, so there's nothing to leak, no server log of what you converted, and no need to trust a third party with sensitive documents. It's also free without the usual catches: no per-file limits, no watermarks, no forced account, and it keeps working offline once loaded.
