Convert PNG to TIFF
Convert PNG images to lossless TIFF for printing, publishing, and professional editing. We preserve transparent areas using alpha channels. All conversions run locally on your device, ensuring complete privacy.

How to use
- 1
Drag and drop your PNG files above, or click to choose them. You can upload multiple files at once.
- 2
Click "Convert" to process each file into an uncompressed TIFF. We automatically preserve your transparent regions.
- 3
Download your finished TIFF files individually, or grab them all in a ZIP file if you converted multiple images.
FAQ
- Do you preserve PNG transparent backgrounds?
- Yes. TIFF supports alpha channels, allowing us to keep transparent regions intact. We save them as unassociated alpha to ensure they display correctly in most professional editing programs.
- Why should I convert to TIFF?
- TIFF is the standard format for high-end printing, publishing, and archiving. While the visual quality matches a lossless PNG, many professional print and editing workflows explicitly require TIFF files.
- Why is the TIFF file so much larger than my PNG?
- TIFF saves files uncompressed, resulting in much larger file sizes (roughly width × height × 4 bytes). Use TIFF for print and archiving, and stick to PNG for web and screen use.
- Do you upload my files to a server?
- Never. We run the entire conversion process locally in your browser. We never upload files, and they clear from memory as soon as you close the page.
PNG Is Already Lossless — So Why Convert to TIFF?
Unlike converting a JPG to TIFF, this one needs justifying, because PNG is already lossless. If your goal is preserving quality, there is nothing to gain: both formats keep every original pixel. The reason for this conversion is almost never image quality. It is compatibility.
Print production specs, public records preservation standards, legacy document management systems, and the import formats of certain professional editing software sometimes name TIFF specifically. That is when you move a PNG to TIFF — not because the image gets better. If nobody asked for TIFF, leaving the file as PNG is almost always the better call.
Identical Quality, Dramatically Larger Files
The cost is size. PNG compresses runs of repeated colour; uncompressed TIFF writes out every pixel as a full 3 bytes. We saved the same 1600×1067 image in both formats and measured the actual bytes.
| Source type | PNG (lossless) | TIFF (uncompressed) | TIFF vs PNG |
|---|---|---|---|
| Flat graphic (logo, illustration) | 23 KB | 5,002 KB | 217× |
| Screenshot (mostly text) | 94 KB | 5,002 KB | 53× |
| Photograph (with grain) | 3,591 KB | 5,002 KB | 1× |
The extreme case is flat graphics like logos. An image that needs 23 KB as PNG becomes 5,002 KB as TIFF — 217 times larger. The fewer colours an image uses, the better PNG compresses it, and TIFF throws that entire advantage away. Photographs narrow the gap to about 1×, because PNG struggles to compress them either.
Notice too that all three TIFF values are the same. With no compression applied, size depends only on pixel count, never on content — which means you can work out the result before converting. Width × height × 3 bytes.
Transparency Survives the Trip
The usual worry when moving a PNG anywhere is the transparent background, and here it is not an issue. TIFF supports an alpha channel, so transparent areas carry over intact. There is no fill colour to choose the way there is when converting to JPG.
How the receiving application interprets that alpha channel is a separate question. Print workflows, where transparency has little meaning, may flatten it onto white. If the transparency matters to your final output, confirm the expectation before you submit.
When This Conversion Is the Wrong Move
- Publishing on the web — most browsers cannot display TIFF inline at all.
- Sharing by chat or email — the file grows many times over and the recipient likely can't open it.
- "Archiving at higher quality" — PNG is already lossless, so there is nothing to gain.
- Icons, sprites, and other web assets — PNG is the native standard there.
The Short Version
If someone requires TIFF, convert. If not, keep the PNG. The image is identical either way; all that changes is the file size and where the file will open.
