MillFile compresses PDFs to exact size limits from 100 KB to 20 MB and converts camera RAW files to JPG, all in your browser with no upload or account needed.
What it is
MillFile is a browser-based PDF compression and RAW image conversion tool. It rebuilds PDFs to exact size limits that web forms demand, from 100 KB to 20 MB, using a two-step process: first a lossless rebuild that preserves selectable text, then adaptive page rendering only if needed. The tool also converts camera RAW files (ARW, CR2, CR3, NEF, DNG, ORF, RAF, RW2) to full-resolution JPG. All processing happens in your browser with no file upload, no account creation, no subscription, no watermark, and no daily quota. The project is built and maintained by one independent developer.

Questions from the bench
- What is MillFile?
- MillFile is a browser-based tool that compresses PDFs to precise size limits from 100 KB to 20 MB and converts camera RAW files to JPEG. Both features run entirely on your device with no upload, no account, and no fees.
- How is MillFile different from other online PDF converters?
- Most converters upload your document to their server, creating queues, daily limits, and charges. MillFile works entirely in your browser on your device, which keeps confidential documents confidential and keeps the price at zero.
- Can I use MillFile without an internet connection?
- Yes, after the initial page load. The PDF engine, zip packer and styles are all loaded from the site's domain, so once the page is loaded you can disconnect and compress files normally.
- Why do websites reject my PDF?
- They cap file size, commonly somewhere between 100 KB and 1 MB, while scanners and Word export well above those numbers. Compressing to the stated cap is the whole fix.
- Is there a file size or usage limit?
- There is no account, no watermark and no daily quota. Larger files simply take longer, because pages are rendered one at a time on your own device.
