Flashdown
Convert PDF, DOCX & TXT to Markdown — right in your browser
Drop in a PDF, DOCX, or TXT file and get clean Markdown back in seconds. No uploads, no signup, no server — everything runs client-side in your browser tab. Built for devs, technical writers, and Obsidian/Notion/Logseq users who live in plain text.
Hey everyone 👋
I built Flashdown because I kept converting docs to Markdown for my Obsidian vault and every existing tool wanted me to upload my file to some server first. That felt unnecessary for something as simple as text extraction.
Flashdown does the whole conversion in your browser — no backend, no file ever leaves your machine. Drop a PDF, DOCX, or TXT file in, get clean Markdown out. Works offline once the page loads.
Right now it handles:
PDF (extracts real text layers — not OCR yet, that's next)
DOCX (headings, bold/italic, links, lists, tables)
TXT (cleans up spacing/line breaks into proper Markdown)
Would love feedback on:
What other formats you'd want (HTML? RTF? Google Docs export?)
Edge cases where the Markdown output looks wrong
Whether OCR for scanned PDFs is worth building next
Try it here: https://flashdown.co.in — no signup needed, just drop a file.
The client-side approach is genuinely useful since nothing leaves your machine, and the Markdown output was surprisingly clean on a messy PDF I threw at it. Will be keeping this bookmarked.
The fact that everything runs client-side with zero uploads is such a thoughtful call, especially for anyone handling sensitive docs. Love that it just respects your privacy without making a big deal about it.
One thing I'd love to see is batch processing, drag in a whole folder of mixed files and get a zip of converted markdowns back. Would save a ton of time when migrating older notes into Obsidian.
Dragged a 40-page PDF in and the headings and code blocks came out clean, no server hop needed. Love that I can close the tab and keep my docs private.
runs locally in the browser and still gives me clean markdown from a messy pdf, exactly the kind of tool i wish existed an hour ago.
