Nanofy: Photo & PDF Compressor

Need a photo under 100 KB for a form? Set the exact size you want and Nanofy gets there — on your device, with nothing uploaded.

Nanofy makes your photos and PDFs smaller — quickly, and without sending a single file anywhere.

Everything happens on your device. No account, no upload, no waiting on a server. That matters when the file is an ID scan, a contract or a medical form.

PHOTO COMPRESSOR Reduce photo size from MB to KB in seconds. Pick a preset — High Quality, Balanced, Small Size — or let Auto choose for you.

REACH AN EXACT FILE SIZE Need a photo under 100 KB for an application form? Choose the size you need — 20 KB, 50 KB, 100 KB, 200 KB, 500 KB, 1 MB or 2 MB — and Nanofy works toward it. If that size isn't reachable without wrecking the image, we tell you the closest we managed instead of pretending we hit it.

And if a photo is already small enough, Nanofy leaves it alone rather than handing back a bigger file.

BATCH COMPRESSION Select many photos and compress them in one pass. Every file gets its own before-and-after size, and one unreadable file never sinks the rest of the batch.

PDF COMPRESSOR Shrink PDF file size for email limits and upload forms. Text stays selectable and searchable — Nanofy re-encodes the images inside the document instead of flattening your pages into pictures. When a PDF turns out to be mostly text, it tells you there was little to compress rather than reporting a meaningless result.

PHOTO TO PDF Turn one photo or a stack of them into a single PDF. Choose A4, Letter, or keep the original page size.

PDF TO PHOTO Export every page of a PDF as a JPG or PNG.

MERGE AND SPLIT PDF Combine several PDFs into one, split a PDF into single pages, or pull out a page range. Pages are copied, not re-rendered, so nothing is degraded.

RESIZE AND CONVERT Scale photos to 25%, 50% or 75%, with the aspect ratio kept. Convert between JPG, PNG and HEIC — useful when an upload form rejects the HEIC photos your iPhone takes by default.

WORKS OFFLINE Nanofy needs no connection. Your files never leave your device and are never uploaded for processing.

PRIVATE BY DESIGN Nanofy uses the system photo picker, so it only ever sees the files you pick — it never asks for access to your whole photo library. This version contains no ads and no analytics, and collects nothing about you.

16 LANGUAGES English, Spanish, Turkish, Portuguese, Hindi, Indonesian, German, French, Japanese, Korean, Italian, Arabic, Russian, Vietnamese, Thai and Polish — switchable inside the app.
