What This Tutorial Covers

This tutorial walks you through converting PNG images to TIFF format using the browser-based tool on this site. No software installation required. You will learn how to add files, understand the per-file status system, use batch ZIP download, and verify your output TIFFs for print and archiving workflows.

For background on why you might want TIFF and when to use it, see the companion PNG to TIFF Complete Guide.

What You Need

• One or more .png files to convert
• A modern browser: Chrome, Edge, Firefox, or Safari (2023 or later)
• No account, no software, no subscription

Step 1: Open the Converter

Navigate to dataconversioncenter.com/image-tools/png-to-tiff/. The page loads the JSZip library from CDN for optional ZIP bundling — no other plugins are needed. The TIFF encoder is written in pure JavaScript and runs entirely in your browser. No data leaves your device at any point.

Step 2: Add Your PNG Files

You have two ways to add files:

• Drag and drop: Open your file manager and drag one or more .png files directly onto the drop zone labelled "Drop PNG files here". The zone highlights in blue when you hover over it with files.
• Browse: Click anywhere on the drop zone (or the "Browse Files" link) to open your file picker. Select multiple files using Ctrl+click (Windows) or Cmd+click (Mac).

After adding files, thumbnail previews appear in the Input Files grid. Each card shows the filename, file size, and a "Ready" status badge. Thumbnails are generated client-side from the PNG data — this does not upload anything.

Step 3: Choose Download Options

Below the drop zone is the options bar:

• Download as ZIP (unchecked by default): Leave this unchecked to download each TIFF file individually after conversion. Check it to bundle all converted TIFFs into a single timestamped ZIP file for convenient batch downloading.

You can always change this setting before clicking the Download All TIFFs button — you do not need to decide before converting.

Step 4: Convert to TIFF

Click the blue Convert to TIFF button. The tool processes files in pairs for efficiency. As each file converts:

• The status badge in the Input grid changes from "Ready" → "Converting…" → "Converted" (green) or "Error" (red)
• The progress bar advances and shows "Converted X of Y…"
• Converted files appear in the Output Files grid with a thumbnail and a per-file download button

For typical PNG files the conversion is near-instant. Larger files (high-resolution print-quality PNGs) may take a second or two per file while the browser reads and encodes the pixel data.

Step 5: Download Your TIFFs

Once conversion completes, a summary banner confirms the results. You have several download options:

• Per-file download: Click the "⬇ Download TIFF" button on any output card to download that file immediately.
• Download All TIFFs: Click the bulk download button to trigger individual downloads for all converted files in sequence.
• Download ZIP: If you checked "Download as ZIP" earlier, the button reads "Download ZIP" and packages all TIFFs into a single archive named dataconversioncenter_png_to_tiff_YYYYMMDDHHMM.zip.

After downloading, the tool automatically resets so you can start a new batch.

Step 6: Verify Your TIFF Output

Before sending TIFFs to a print lab or archiving system, it is good practice to verify the output:

• macOS: Open the TIFF in Preview. Check Tools → Show Inspector → General tab to confirm dimensions, colour space (RGB), and DPI.
• Windows: Right-click the TIFF → Properties → Details tab to see image dimensions and DPI.
• Photoshop: Open the file and check Image → Image Size to verify pixel dimensions and resolution.
• GIMP: Open the file and check Image → Image Properties for all metadata.

If your print provider requires CMYK colour mode, open the TIFF in Photoshop and convert via Image → Mode → CMYK Color, selecting the appropriate ICC colour profile for your print process.

Batch Conversion Tips

• There is no hard limit on the number of files you can add. For very large batches (50+ high-resolution files), convert in groups of 20–25 to avoid browser memory pressure.
• File naming is preserved. Each output TIFF is named identically to its source PNG, with only the extension changed to .tiff. This makes it easy to match inputs and outputs in a batch workflow.
• Use ZIP for large batches. If you are converting many files, the ZIP option is far more convenient than triggering dozens of individual browser downloads.

Troubleshooting

File shows "Error" status: The file may not be a valid PNG, or it could be a corrupted or truncated file. Try opening it in an image viewer first to confirm it is readable, then retry the conversion.

Output TIFF is very large: Uncompressed TIFF files can be significantly larger than their PNG source. This is expected — TIFF without compression stores raw pixel data. For a 3000×4000 pixel RGBA image, expect around 48 MB uncompressed. If your workflow requires smaller files, use GIMP or Photoshop to re-save with LZW compression after conversion.

Browser asks to block multiple downloads: When downloading many files individually (not via ZIP), your browser may show a prompt to allow multiple downloads from this site. Click "Allow" to proceed. Using the ZIP option avoids this prompt entirely.
