Hi Product Hunt! I'm Jason, a solo developer from the UK.
Every "free online compressor" I tried wanted me to upload my files to someone else's server first, often with size caps, queues, watermarks or an account wall. For client PDFs and personal photos that never sat right with me, so I built nanofile.
Everything runs inside your browser tab. There is no upload endpoint at all, so there is nothing to intercept or retain. Load the page, pull your wifi, and it still works.
What it does:
36 formats: JPG, PNG, WebP, AVIF, HEIC, GIF, PDF, DOCX, XLSX, PPTX, MP3, WAV, FLAC, fonts, SVG, HTML/CSS/JS, EPUB, GLB, STL, ZIP and more
Drop a batch of mixed files and it detects each format by its magic bytes, then routes you to the right tool
Before/after slider so you can check quality before saving
Format conversions too (HEIC to JPG, WebP to PNG, Word to PDF, WAV to MP3 and others)
No account, no watermark, no daily limit
Under the hood it's real codecs compiled to WebAssembly (MozJPEG, libwebp, oxipng, libheif, pdf-lib and friends), only loaded on the page that needs them.
I'd love to hear which formats or conversions you'd like next, and any files where the results disappoint you.
