I have upgraded my plugin, and now you can directly import pptx into Figma Slides using my plugin while maintaining the original visual effects and editability. I have submitted the new version, you can try it again, and this will save you a lot of time!

i build a plugin so You can now Directly import Powerpoint .pptx to Figma！

Hello designers!

Many times, I have to visually upgrade some old pptx files in Figma, but the need to rebuild them every time is very tedious, so I wrote this plugin to import .pptx files into Figma with one click while maintaining the visual effects. If you're tired of rebuilding in Figma, you can try this plugin and happy to see you feedback!

I tried to build a “trustless” file sharing app (browser-only)

I tried to build a “trustless” file sharing app (browser-only)

I build Figma plugins, but recently I ran into a problem:

I needed to share files (PDF / PPT / assets),
and I realized I don’t actually trust any file sharing service.

Not because they’re bad — but because:

they can technically read your files.

So I tried something different

I’m building a file sharing flow where:

everything happens in the browser
files are encrypted before upload
server stores only opaque blobs
the decryption key is in the URL (#key=...)

Meaning:

if you don’t have the link, you literally can’t read the file
even I (the developer) can’t access it

The interesting parts

Client-side processing is painful

Users upload anything:

PDF / PPT / Word / images

Trying to normalize formats inside the browser is way harder than expected
(WASM helps, but still messy)

Encryption is the easy part

Web Crypto API works great.

The real issues are:

large files (100MB+)
memory spikes
blocking UI

→ solution: chunking + Web Workers

UX is the hardest problem

Users don’t care about encryption.

They want:

drag & drop
click “create link”
done

Making something secure feel this simple is the real challenge.

Why I’m sharing this

I’m starting to think:

“trustless apps” might be a real category

Where you don’t need to trust:

the platform
the backend
even the developer

Curious if anyone here has built:

browser-only file processing
large file encryption pipelines
WASM-heavy apps

Would love to hear how you handled performance.
