Print shops, framers and some POD suppliers still specify TIFF. This free converter writes an uncompressed TIFF from your PNG in the browser, keeping every pixel intact — both formats are lossless, so the conversion is a change of container rather than a change of image. Expect the TIFF to be considerably larger than the PNG: that is the format doing what it was designed to do, storing samples plainly so no decoder can disagree about them. Nothing is uploaded.

How to use it
- Check the output is set to TIFF — This page opens with the output format already set to TIFF, so there is nothing to configure if that is what you came for. If you actually wanted something else, change it here — the same page converts to PNG, JPG, WebP, TIFF and PDF.
- Add your PNG files — Drag them onto the drop area or click to choose them — one file, or up to thirty at once. They are read in your browser, so nothing is uploaded, there is no queue and no account is needed.
- Let it convert — There is no Convert button — conversion starts as soon as a file is added, and the results panel shows the total size going in and coming out so you can see what the change cost or saved.
- Download the results — Each converted file has its own download link. If you converted several, "Download all as ZIP" saves the whole set in one action.
The problem this solves
A supplier's spec sheet says "TIFF, 300 DPI, no compression" and your artwork is a PNG. The usual routes are a Photoshop licence you do not need, or an upload-based converter you have to trust with unreleased artwork.
What it does
Uncompressed, maximally compatible
The TIFF is written with plain uncompressed samples, which is what a RIP or a print shop's workflow reads without argument. Exotic TIFF compression is where compatibility problems usually start.
Nothing is lost
PNG and TIFF are both lossless. The pixels that go in are the pixels that come out — no re-encoding, no artefacts.
Alpha kept
A transparent PNG becomes a TIFF with its alpha channel intact rather than being flattened first.
Whole folders at once
Drop in up to thirty files and every one is converted. Multiple outputs download together as a ZIP, so a set of listing images is one action rather than thirty.
Nothing is uploaded
The conversion runs in your browser using the same image pipeline the browser uses to show you a photo. Your file never reaches a server, there is no queue, and there is no account to make. It also means a large file is limited by your own machine's memory rather than by an upload cap.
Where it lives in PSDmate
Free and open on this page. Inside PSDmate, print-ready files are produced as part of publishing rather than exported by hand.
Questions
Why is the TIFF so much bigger than the PNG?
Because it is uncompressed. PNG spends effort compressing losslessly; an uncompressed TIFF stores every sample plainly, which is exactly why print workflows like it. A ten-megabyte PNG routinely becomes a hundred-megabyte TIFF.
Does this change my DPI?
No, and neither does any converter. DPI is the relationship between pixel dimensions and the physical size you print at — it is decided when the job is placed, not stored as a property of the image. If your printer wants 300 DPI at A2, what they need is enough pixels, not a different tag.
Does my artwork stay in CMYK?
No. This converter works in RGB, because browsers do. If your print shop requires a CMYK TIFF with a specific profile, that conversion has to happen in a colour-managed application.
Is TIFF better than PNG for printing?
Not inherently — both are lossless, so image quality is identical. TIFF is asked for because print workflows standardised on it decades ago and it carries print metadata that PNG does not.
