NanoFormatZero

Universal Image Converter — JPG, PNG, WebP & AVIF

One converter for every common image format: pick a target — JPG, PNG, WebP or AVIF — drop your images and download the results. HEIC photos from iPhones are decoded automatically before conversion.

Everything runs on a local canvas: no uploads, no waiting in a queue, no watermarks. Convert a single photo or a whole batch — multiple files come back as one tidy ZIP.

FAQ

Why are GIF and TIFF not supported?

GIF conversion would destroy the animation (only the first frame survives) and TIFF support is unreliable in browsers. For those formats use a desktop tool — everything else works here.

Does AVIF export work in every browser?

AVIF export needs a modern Chromium browser (Chrome, Edge, Opera). If your browser can't encode AVIF, you'll get a clear warning — PNG and WebP work everywhere.

Frequently Asked Questions

Everything you might want to know before dropping your first file.

Six privacy-first modules cover the most common file jobs: compress, merge, split, redact and watermark PDFs (Document Surgery); convert HEIC, PNG, WebP and AVIF images (Media Rescuer); scrub EXIF/GPS and PDF metadata (Privacy Shield); count, convert and clean text (Text Tools); sort messy files into folders by real signatures (File Organizer); and create or safely open ZIP archives (Archive Tools). Everything runs in your browser — no installs, no accounts.

Open Document Surgery and choose PDF Compressor, then drop your file. The Smart WASM Engine recompresses images and streams inside the PDF locally on your device, and you download a smaller file in seconds. Nothing is uploaded, and you stay in control of the quality-versus-size balance.

Drop your iPhone photos into Media Rescuer's HEIC to JPG tool. The HEIC decoder runs entirely in your browser and outputs universally readable JPGs — process a whole batch and get everything back in one ZIP. It works on Windows, Mac, Android and any modern browser.

Open Privacy Shield and drop the photo — the EXIF/GPS cleaner strips embedded location, camera, device and date information, then you download a clean copy. Not sure what a file hides? Run it through the Metadata Viewer first to see every tag before you clean it.

In Document Surgery, PDF Merger combines as many PDFs as you like into one document in the order you choose, while PDF Splitter cuts a file into single pages or custom ranges. Both run locally, so confidential contracts and records never leave your device.

Use the Universal Converter in Media Rescuer: pick a target format, drop your images and download the results — HEIC input is decoded automatically. PNG and WebP work in every browser; AVIF export needs a modern Chromium browser like Chrome or Edge, and you get a clear warning if yours cannot encode it.

Drop the archive into Archive Tools' ZIP Opener. You get a full content listing with a safety report first — executable files are flagged, suspicious path entries are neutralized and unusual expansion ratios trigger a zip-bomb warning — then download only the files you need.

Use PDF Redactor in Document Surgery: draw over names, amounts or passages and the tool removes the underlying text data, not just the visible pixels. A cover-up box can be lifted in other editors — true redaction cannot.

Yes — every tool runs on your device using WebAssembly modules, Web Workers and JSZip. Your files go straight from your disk into browser memory and back out as downloads; no server ever sees them. An internet connection is needed to load the tools themselves (libraries come from a CDN), but your files never travel over the network.

Yes — any modern browser on phone, tablet or desktop, with nothing to install. You need an internet connection to load the tools; from then on your files are processed entirely on your device and never uploaded.

Completely free: no accounts, no daily limits, no watermarks and no premium tier. Because all processing happens on your hardware instead of our servers, the cost of running the site stays near zero — that is the whole business model.

PDFs for all document tools; JPG, PNG, WebP, AVIF and HEIC for image conversion and compression; any file type for organizing and ZIP packaging; and plain text for the text tools. ZIP archives can be created and opened, with encrypted (password-protected) ZIPs as the one documented exception.
