How to Convert PNG to TIFF Free — 4 Methods for Print & Archiving (2026)

How to Convert PNG to TIFF: The Print and Archival Upgrade Guide

PNG to TIFF conversion has one primary use case: you need your image in a format that professional print workflows, archival storage systems, or high-end imaging software will accept without complaint. If a print shop, medical imaging platform, or publishing tool is rejecting your PNG file and asking for TIFF, this guide covers four free methods that work on Windows, Mac, and the command line.

Before the step-by-step instructions, it is worth addressing three things that every other guide on this keyword ignores: how much larger your TIFF file will be, which TIFF compression option to choose, and how CMYK color mode interacts with PNG-sourced files. These three topics explain 90% of the confusion people encounter when converting PNG to TIFF.

PNG vs TIFF: Two Formats Serving Different Masters

PNG and TIFF are both lossless formats — but they were designed for completely different jobs.

PNG was designed for web delivery: small file sizes, universal browser support, full alpha transparency, and fast decoding. It is the correct format for logos, screenshots, web graphics, and UI assets that need to load quickly in a browser.

TIFF was designed for professional imaging workflows: print, medical, publishing, and archival. It supports multiple color modes (RGB, CMYK, Lab, Grayscale), high bit depths (8, 16, 32-bit per channel), embedded ICC color profiles, DPI metadata, layers, multiple compression schemes, and multi-page documents. No web browser renders TIFF files — that is intentional. TIFF is a delivery format for print shops and imaging software, not for the web.

The conversion from PNG to TIFF is typically a workflow transition: you created the image in PNG for web use, and now you need it in TIFF for print or archival storage. Both formats are lossless, so zero image quality is lost in either direction.

The File Size Reality: TIFF Is Larger Than PNG

This is the first thing every converter tool omits from its documentation, and it surprises users every time.

PNG uses the Deflate compression algorithm — the same algorithm used in ZIP files — to compress image data losslessly. TIFF offers several compression options, and the default in many tools is no compression at all (raw, uncompressed pixels).

Uncompressed TIFF stores pixels at 3 bytes per pixel for RGB images (red, green, blue channels at 8 bits each). The file size is entirely predictable:

Uncompressed TIFF size = width × height × 3 ÷ 1,048,576 = megabytes

For a 1920×1080 image: 1920 × 1080 × 3 ÷ 1,048,576 = 5.93 MB — regardless of content.

Here is how that compares across compression modes and image types:

TIFF with ZIP/Deflate compression is essentially the same algorithm as PNG. For flat-color graphics, logos, and screenshots, Deflate TIFF will be very close to PNG in file size. For photographs with complex color gradients, PNG is still significantly smaller because it was designed specifically for that tradeoff.

Which TIFF Compression Should You Choose?

This decision comes up every time you export a TIFF, and the right answer depends on where the file is going:

The standard choice for professional workflows is LZW. It is supported by every imaging application that opens TIFF (Adobe Photoshop, GIMP, Affinity Photo, Lightroom, InDesign, QuarkXPress, print RIPs), and it keeps file sizes manageable without introducing any quality loss.

ZIP/Deflate is the best choice for long-term archival storage where file size matters and you are confident the destination software supports it.

Never use JPEG-in-TIFF for archival purposes. It introduces lossy compression into a format people typically choose because they want lossless quality. This option exists for legacy print workflows and should not be used for new files.

Transparency: The Good News for PNG Users

Unlike the PNG to BMP conversion — where transparent areas get filled with white because BMP has no alpha channel — TIFF fully supports alpha transparency.

If your PNG has a transparent background, your TIFF output will also have a transparent background, stored as a full 8-bit alpha channel (256 levels, identical to PNG). Logos, UI assets, and design files with transparent backgrounds convert cleanly to TIFF with no white boxing or unexpected fills.

The one exception: if you are converting to CMYK TIFF for print (discussed in the next section), CMYK color mode does not support transparency. But for standard RGB TIFF output, transparency is fully preserved.

CMYK and DPI: The Print Workflow Details

This section is why designers and photographers land on this keyword — and it is completely absent from every competitor result.

CMYK Color Mode

Most PNGs use the RGB color mode — red, green, blue channels — which is correct for screen display. Print workflows, however, use CMYK (cyan, magenta, yellow, black) — the inks in a commercial printing press.

Standard online PNG to TIFF converters, including browser-based tools, convert to RGB TIFF. If your print shop requires CMYK TIFF — which many offset printing workflows do — you will need professional imaging software to perform the RGB-to-CMYK color conversion.

For CMYK TIFF conversion:

If your print shop accepts RGB TIFF, which many do for digital/inkjet printing, a standard browser-based or command-line converter is sufficient. Ask your printer which they require before converting.

DPI / PPI Resolution Metadata

TIFF files can embed DPI (dots per inch) metadata that print software reads to determine physical output dimensions. PNG also stores this metadata, and a proper TIFF converter will preserve it from your source PNG.

However, DPI metadata in an image file does not change the pixel dimensions. A 1920×1080 PNG at 72 DPI and the same image at 300 DPI contain exactly the same number of pixels. The DPI tag only tells printing software how large to render the image on paper.

For print at standard 300 DPI:

If your PNG was created for web at 72 DPI, converting to TIFF and changing the DPI tag to 300 does not magically create more pixels — it just tells the printer to print the existing pixels smaller. For genuinely high-quality print, you need sufficient pixels to begin with.

Method 1: Convert PNG to TIFF in Your Browser (No Upload)

The fastest way to convert PNG to TIFF without software is using a browser-based converter that processes your files locally on your device using WebAssembly.

Unlike FreeConvert, Convertio, CloudConvert, Zamzar, or Picflow — all of which upload your files to their servers — PhotoFormatLab's PNG to TIFF converter runs entirely in your browser. Your files never leave your device.

Steps:

Batch conversion is fully supported — drop multiple PNG files and download all TIFFs at once. Works on Chrome, Firefox, Safari, and Edge on Windows, Mac, Linux, iPhone, or Android. No account required.

Why privacy matters for PNG source files: PNG is the standard format for design exports, wireframes, UI screenshots, and internal business graphics — files that often contain confidential or proprietary information. Server-based converters transmit those files to third-party infrastructure outside your control. For a detailed explanation of how browser-based conversion works and why it is more secure, see our guide on converting images without uploading to a server.

Method 2: Convert PNG to TIFF on macOS Using Preview

Preview, built into every Mac, can export PNG files as TIFF with no additional software.

Single file:

Batch conversion on macOS:

Preview exports all selected images simultaneously. Note: Preview exports RGB TIFF by default. For CMYK TIFF, use Affinity Photo or Adobe Photoshop.

Method 3: Convert PNG to TIFF on Windows

Windows does not ship with a tool that directly exports TIFF, but IrfanView handles it cleanly and is free.

Using IrfanView (free):

Batch conversion with IrfanView:

Method 4: Convert PNG to TIFF with ImageMagick (CLI)

ImageMagick gives you precise control over compression type, bit depth, color mode, and DPI metadata — and supports automated batch processing.

Installation

macOS (Homebrew):

```bash

brew install imagemagick

```

Ubuntu/Debian:

```bash

sudo apt install imagemagick

```

Windows: Download from imagemagick.org and add to PATH.

Basic Conversion

```bash

convert input.png output.tiff

```

ImageMagick defaults to no compression. For LZW compression (recommended):

```bash

convert input.png -compress lzw output.tiff

```

For ZIP/Deflate compression (smallest lossless TIFF):

```bash

convert input.png -compress zip output.tiff

```

Setting DPI Metadata

```bash

convert input.png -compress lzw -density 300 output.tiff

```

The -density 300 flag embeds 300 DPI metadata in the TIFF. This tells print software to render the image at 300 dots per inch. It does not add or change pixels.

Batch Convert an Entire Folder

```bash

for f in *.png; do

convert "$f" -compress lzw "${f%.png}.tiff"

done

```

Windows PowerShell:

```powershell

Get-ChildItem *.png | ForEach-Object {

& magick $_.FullName -compress lzw ($_.BaseName + ".tiff")

}

```

Converting to 16-bit TIFF

For archival workflows that require 16-bit color depth:

```bash

convert input.png -compress lzw -depth 16 output.tiff

```

This produces a 48-bit RGB TIFF (16 bits per channel × 3 channels). Most PNG files are 8-bit per channel, so this conversion stores the existing 8-bit data in a 16-bit container — file size doubles but no new pixel information is added.

When Should You Convert PNG to TIFF?

Convert PNG to TIFF when:

Do not convert to TIFF for web delivery. Browsers do not render TIFF files. If you need a smaller web-ready format, consider PNG to WebP conversion for 25–35% smaller files or PNG to AVIF for up to 50% reduction.

Frequently Asked Questions

Does converting PNG to TIFF lose any quality?

No. Both PNG and TIFF use lossless compression (or no compression at all). Every pixel in your PNG is reproduced exactly in the TIFF output. The only exception is JPEG-in-TIFF — a compression option that introduces lossy quality loss. Stick with LZW or ZIP compression and quality is entirely preserved.

Why is my TIFF file so much larger than my PNG?

PNG uses Deflate compression, which is very efficient for the kind of data found in graphics and screenshots. If your converter outputs uncompressed TIFF, the file stores raw pixel data — 3 bytes per pixel for RGB — with no compression at all. A 1920×1080 image is always 5.93 MB uncompressed, regardless of how small the source PNG was. To reduce TIFF size, choose LZW or ZIP compression in your converter or export settings.

Does TIFF support transparency like PNG?

Yes — unlike BMP, TIFF fully supports alpha transparency. If your PNG has a transparent background, your TIFF output will also have a transparent background stored as an 8-bit alpha channel. The one exception: CMYK TIFF does not support transparency, because the CMYK color model used in print does not have an alpha channel concept.

Do I need to convert to TIFF for printing, or will PNG work?

Many print services — particularly digital and inkjet printers — accept PNG files directly. Offset printing and professional publishing workflows traditionally require TIFF, often in CMYK color mode. Check with your specific print shop before converting: if they accept high-resolution PNG, you save a conversion step. If they require TIFF, ask whether they need RGB or CMYK TIFF.

What is the best TIFF compression for print use?

LZW is the standard choice for print: it is lossless, universally supported by print software and RIP workflows, and keeps file sizes significantly smaller than uncompressed TIFF. ZIP/Deflate is also lossless and produces smaller files, but has slightly lower compatibility with older RIP (Raster Image Processing) systems. Ask your print shop if you are unsure — most modern print environments support both.

Can I convert a PNG with transparent background to TIFF without getting a white background?

Yes — unlike BMP, TIFF preserves alpha transparency from PNG. When you convert using PhotoFormatLab, Preview on macOS, or ImageMagick with default settings, the transparent areas in your PNG become transparent areas in your TIFF, stored as a full alpha channel. You only lose transparency if you explicitly flatten the image or convert to CMYK TIFF (which does not support alpha).
