Show HN: I've built a web based pdf/docx/pptx editor, the format .ldf

Posted by yeargun on Friday October 31, 2025 @07:36PM
from the show-hn dept.

When compared to pdf, it's:

- Fully editable, collaborative

- Faster

- Smaller in size

- Fully streaming (you only load the pages you view/about to view)

- Most importantly its not IRREVERSIBLE. Meaning, you dont need to do llamaindex or use pdf parsers. Its some protobuf schemes

- Fully HTML ally

- Might take less resources (greener)

- AI native.

I am planning to make it like canva+. And its also for education.

Please do register and upload some pdf/pptx/docx at page https://learny.academy/doc

if you dont want to 'google sign in'. username:ppl pw:12345

I am gradualy making it more stable. For very very text heavy pdfs, texts go a little corrupted. Its better for slide like pdfs

remove the friction of registration (or at least create a demo page just for the purpose of trying your editor) & we'll try :)
