About UploadOff and FileConvertLab

In their own words, as submitted to SaaSHub.

FileConvertLab

That also means no daily limits, no file size caps and no account. Image converters: HEIC to JPG or PNG (date taken kept); WebP, PNG...

Questions & Answers

As answered by people managing UploadOff and FileConvertLab.

What makes your product unique?

UploadOff's answer

The converters run in your browser, so files are never uploaded. A result can also go straight on to the next tool: remove pages from a slide deck, then turn the pages into images, with no download and re-upload in between.

How would you describe the primary audience of your product?

UploadOff's answer

People who need a quick conversion on whatever device they have: iPhone photos (HEIC) a form won't accept, phone photos of documents that need to be one PDF, slides that need to become images. Nothing to install, so it also works on shared or work computers.

What's the story behind your product?

UploadOff's answer

I wanted to turn a few phone photos of documents into one PDF without handing them to some converter's server, so I built converters that run entirely in the browser tab.

Why should a person choose your product over its competitors?

UploadOff's answer

Most online converters upload your file and cap how many you can do. UploadOff does the work on your device, so there are no file limits, no size caps and no sign-up, and private documents like pay stubs never leave your phone or computer.

Which are the primary technologies used for building your product?

UploadOff's answer

A web app with compiled (WebAssembly) decoders and encoders running in the page, plus per-browser handling so the same file comes out right in Safari, Chrome and Firefox.
