👋 I'm Vitaliy, and I built formatmath: a free file converter with no limits. Here's the idea behind it. Almost every online converter works the same way: you upload your photo or document to their server, they convert it there, and you download the result. That means your private files...

Questions & Answers

As answered by people managing WebViewGold and FormatMath.

Why should a person choose your product over its competitors?

FormatMath's answer:

Privacy and no limits. Popular converters like CloudConvert, Convertio, FreeConvert or Zamzar upload your files to their servers and limit free use by file size, number of conversions or waiting time. FormatMath converts locally, so private photos, scans and documents stay on your device, and you can batch-convert hundreds of files and download them as one ZIP for free. It also covers formats many converters skip, such as camera RAW (CR2, CR3, NEF, ARW, DNG and more), PSD, JPEG XL and CBZ.

Who are some of the biggest customers of your product?

FormatMath's answer:

Individual users (no accounts required, so we don’t track customers)

What makes your product unique?

FormatMath's answer:

Every tool runs entirely in your browser. When you convert a file, it’s read and processed on your own device and saved straight back to it, so it’s never uploaded and our server never sees it. Because there’s no server-side processing to pay for, there are also no file size caps, no daily limits, no watermarks and no sign-up. It works offline once a page has loaded.

How would you describe the primary audience of your product?

FormatMath's answer:

iPhone users who need HEIC photos as JPG for websites, forms and Windows PCs Photographers who need quick JPG previews from camera RAW files Office workers and students who merge, split, rotate or compress PDFs Privacy-conscious people who don’t want to upload personal files to a server Developers who need quick JSON, YAML, CSV, Base64, UUID or regex tools

What's the story behind your product?

FormatMath's answer:

I kept needing to convert iPhone photos and PDFs, and every online converter wanted me to upload private files to an unknown server, then limited me by file size or number of conversions. Modern browsers can decode and encode most formats themselves, so I built FormatMath to do all the work on the user’s device instead. It started with HEIC to JPG and grew into image, RAW, PDF, compression, photo-privacy and developer tools, in English and Ukrainian. I also run fee-math.com, a set of free fee calculators for online sellers built on the same no-upload principle.

Which are the primary technologies used for building your product?

FormatMath's answer:

TypeScript and Astro (static site) Cloudflare Workers and D1 (hosting, blog and anonymous usage stats) WebAssembly codecs (libheif for HEIC, jSquash for JPEG XL and WebP) pdf.js and pdf-lib for PDF rendering and editing Canvas and Web Workers for in-browser image processing fflate (ZIP), UTIF (TIFF), ag-psd (Photoshop files), exifr (metadata), yaml
