Compress a PDF to the Exact Size a Form Asks For

A set of browser tools that do their work on your own device. One compresses a PDF to a precise size limit - 100 KB, 300 KB, 1 MB or anything between. The other converts a camera RAW file (ARW, CR2, NEF, DNG and more) to JPEG. Both are free, need no account, and never upload your files.

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.

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.

Most converters upload your document to a server, then queue you or charge for higher limits. MillFile works entirely on your device, which keeps confidential documents confidential and keeps the price at zero.

The smallest target you can pick here is 100 KB, so a 50 KB form cannot be answered directly. Every document also has a floor: when a file will not fit, the badge reports the smallest size actually reached instead of guessing. To get under 100 KB the source has to shrink first - scan at a lower resolution, drop blank pages, keep one page per file.

Open the tool in Chrome on Windows, Mac, Linux or Android and click the box to choose a file. On an iPhone or iPad the same tap opens the Files app, where camera scans and mail attachments live, and the finished PDF is saved back there. Neither path uploads anything. A long document takes longer on a phone, because pages are rendered one at a time.

When the lossless rebuild is enough, pages keep their text, fonts and clickable links. Pages that must be re-rendered become pictures, and the links, fillable fields and signatures on them are gone. Either way the bookmark outline and the stored document title do not carry into the new file. If a submission needs a live form, send the original.

MillFile. There is no upload step at all: the PDF is read from disk, rebuilt in browser memory and handed back as a download, so the document appears in no network request. Load the page, disconnect from the internet and compress a file - it still works, which is the quickest way to confirm nothing was sent.

Only when the file is not sent anywhere. Identity documents are the ones people most need to shrink - visa, admission and recruitment portals routinely cap them at 100 KB - and the worst ones to hand to an anonymous server. Here the scan is processed inside the tab, so the only copy that leaves your device is the one you downloaded.

Yes, once the page has loaded. The PDF engine, the zip packer and the styles are all served from this domain, so after the first load there is nothing left to fetch. Turn off Wi-Fi, drop a file, and it compresses and downloads as usual.

There is no trial and no subscription, so there is nothing that can turn into a charge. The site has no account system and no payment page at all: every target size, every batch and the RAW converter are free, with no watermark and no daily quota. The work happens in your browser, so there is no server bill for us to recover from you either.

Not here. MillFile repacks the document's internal structure first - collapsing duplicate objects and compressing the streams - and most text PDFs reach their target that way, with the text still selectable, searchable and copyable. Pages are re-rendered only when that repack alone cannot reach the target, a page that carries text is never rendered below about 94 dpi, and if the re-rendered file turns out no smaller than the repack, the repack is what you get.
