S Converter
Convert any file on Windows: offline, free, one click
All-in-one file converter for Windows. Images (HEIC, RAW, WebP), video with GPU speed, audio, Word/PowerPoint to PDF without Office, PDF tools, watermarks and ZIP passwords. Everything runs on your PC: no uploads, no ads, no account.
Hi Product Hunt! 👋 I'm Sujith, and S Converter is my first public app.
I built it because every converter I tried either wanted my files uploaded to someone's server, covered them in ads, or only did one thing. I was using five different tools for photos, videos and PDFs. So I made one app that does it all, entirely on your own PC.
What it does:
• Images: HEIC (iPhone), WebP, AVIF, RAW, PNG, JPG, TIFF, in batches
• Video: MP4, MKV, MOV, WebM, GIF, sped up by your graphics card
• Audio: MP3, FLAC, WAV, AAC, or pull the sound out of any video
• Word, PowerPoint and Excel to PDF, without Office installed
• PDF tools, watermarks, and ZIPs with passwords
My favourite part is Quick Convert: select files in File Explorer, press Ctrl+Alt+C (or right-click), and a wheel pops up at your mouse. Pick a format, and it's done without even opening the app. That's what the video shows.
It's free, with no ads and no account, and nothing is ever uploaded. It's on the Microsoft Store, and updates install automatically.
I'd love to hear what you think: which formats or tools would you want next? I'm here all day to answer questions!
