Nanofy: Photo & PDF Compressor

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 WEBP.

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

PRIVATE BY DESIGN
Nanofy uses Android's 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.
