Quick answer. Paint on Windows and Preview on Mac both save a PNG as TIFF for free. For a folder of images, free batch converters handle it on your own PC, and a paid tool adds preview and support. Worth knowing, PNG is already lossless, so TIFF is about print and archive workflows, not better quality.

Why convert PNG to TIFF?
PNG is built for screens, and it is very good at that. TIFF earns its place elsewhere, in printing, scanning and long term archiving, where it has been the expected format for decades. Print shops and layout apps ask for TIFF, archives standardise on it, and it handles things PNG simply does not, like CMYK colour for press work and, most usefully, holding many images inside one multipage file. That last one is the genuine reason a lot of people convert, turning a folder of PNG scans into a single TIFF document. The goal is fitting the workflow, not chasing a sharper picture.
What TIFF actually changes?
Here is the part a lot of guides get wrong. PNG is already a lossless format, so your image has lost nothing, which means converting it to TIFF cannot add quality or bring back detail that was never missing. A lossless PNG converted to a lossless TIFF is the same picture in a different wrapper. It is also worth knowing that TIFF is not automatically lossless either, since it can carry JPEG compression inside, so if quality matters, pick a lossless compression option like LZW or ZIP, or none at all, when you save. Set expectations honestly, you are converting for compatibility, multipage support and print workflows, and the file will usually get larger, not better.
Converting buys you multipage support and print compatibility, not extra sharpness.
“Going from one lossless format to another is a container change, nothing more, so nobody should expect a PNG to look better once it is a TIFF. The one setting that genuinely matters is the compression you pick on the way out, because TIFF will happily accept JPEG compression and quietly throw away data. Choose LZW or none, and the file you get back is a faithful copy.” Shubham Dixit, Data File reviewer (draft, pending approval)
Convert a PNG to TIFF free on Windows or Mac
For one image, your computer already has everything you need and it costs nothing.
On Windows, with Paint. Open the PNG in Paint, go to File then Save as, choose TIFF as the file type, name it and save.
On Mac, with Preview. Open the PNG in Preview, go to File then Export, pick TIFF in the format menu, and save. Preview also lets you choose the compression, which is worth setting to a lossless option.
Both are free, both stay on your machine, and both are perfect for a file or two. Neither does batches, which is the only real snag.
Batch convert PNG to TIFF free
If you have a folder of PNGs, you do not have to pay to convert them all, and you do not have to upload them anywhere either. Free desktop converters handle batches locally.
IrfanView has a batch conversion window where you point it at a folder, choose TIFF as the output and run the lot in one pass. XnConvert does much the same across Windows, Mac and Linux, with output settings you can tune. GIMP can do it too, though it takes a script, so it suits people who like that sort of thing. All three are free, run on your own PC, and upload nothing.
These are genuinely good answers for most bulk jobs. Where they ask something of you is setup and fiddling, IrfanView’s batch dialog is powerful but dated, XnConvert has a lot of knobs, and none of them hold your hand. If that is fine, you are done here at no cost.
One image, use what you already have. A folder, reach for a batch converter.
A word on online converters
Online PNG to TIFF sites are convenient, and for a random image off the internet they are fine. The thing to understand is what they do, which is take a copy of your file and put it on someone else’s server. That is a poor idea for client work, scanned documents, anything with personal details, or material you are contractually obliged to keep private, and some free sites also cap file sizes or stamp the output. Since Paint, Preview and the free batch converters above all run on your own machine and upload nothing, there is rarely a reason to take the risk in the first place.
Batch convert PNG to TIFF with a tool
A paid converter is not the only safe way to do bulk work, and it would be dishonest to say otherwise. What it buys you is smoothness, a preview so you can check images before they convert, a plain interface with no batch scripting, and someone to ask when something misbehaves. The PCDOTS Image Converter loads a folder of PNG files, previews them, and writes them all to TIFF in one run on your own PC, keeping the image as it was. It runs on Windows and there is a free version to try first. If the free batch tools above already suit you, use those with our blessing.
Batch converting a folder of PNG images into TIFF without uploading anything.
Here are the steps with the screens.
Step 1. Download, install and run the converter on your Windows PC.
Step 2. Click Open and add your PNG files or a whole folder, then preview them.
Step 3. Select TIFF as the output format.
Step 4. Choose a destination on your PC and hit Save to convert the files.
The same tool handles other image jobs too, for instance if you later need to convert PNG to WebP for the web.
The methods compared
Match the route to how many images you have.
| Method | Best for | Good to know |
|---|---|---|
| Paint or Preview | One image, free, already installed | No batch option |
| Free batch converters | A folder, free, stays local | Setup and settings to learn |
| Image Converter | A folder, preview and support | Paid, simple, runs on your PC |
Frequently asked questions
How do I convert a PNG to TIFF on Windows?
Open the PNG in Paint, go to File then Save as, and choose TIFF. That is free and covers a single image. For a folder, use a batch converter instead.
How do I convert a PNG to TIFF on Mac?
Open the PNG in Preview, choose File then Export, and pick TIFF in the format menu. Preview also lets you set the compression, so choose a lossless option.
Can I batch convert PNG to TIFF for free?
Yes. Free desktop converters such as IrfanView and XnConvert convert a whole folder at once on your own PC, with nothing uploaded and nothing to pay.
Does converting PNG to TIFF improve image quality?
No. PNG is already lossless, so nothing was lost to recover. The conversion is about print and archive compatibility, and the TIFF will usually be a larger file than the PNG.
Are online PNG to TIFF converters safe?
They upload a copy of your file to someone else’s server, so avoid them for client work, scanned documents or anything private. Free local tools do the same job without the file ever leaving your machine.
Can I put many PNG images into one TIFF?
Yes, that is a real strength of TIFF, which PNG cannot match. A multipage TIFF holds many images in a single file, which suits scanned documents and archives.
Your PNGs, ready for print and archive
The honest version of this job is short. One image, Paint or Preview already does it for nothing. A folder, a free batch converter handles it locally, and a paid tool is there if you would rather have a preview and a support line than a settings panel to learn. Whichever you use, pick a lossless compression on the way out and skip the upload sites. And keep the original PNGs, because once you understand that TIFF is a workflow choice rather than a quality upgrade, the rest of it is just picking the tool that annoys you least.
