PNG to TIFF converter: lossless, with DPI, free and private
To convert PNG to TIFF free and private, pick a Compression type (LZW by default) and a DPI value (300 by default), drop your PNG files on the dashed upload area or click Select PNG Files, then download each .tif file or Download All (ZIP). The conversion runs in your browser. Nothing is uploaded, and the Network tab in DevTools will show it.
TIFF (Tagged Image File Format) is a container whose tags record how pixels are arranged, how they are compressed and how large the image should print. All three compression choices here are lossless, so the TIFF holds the same 8-bit colour and alpha values as the PNG. Transparency stays as an alpha channel, an embedded ICC colour profile is copied (except in a greyscale PNG with transparency, which is converted to sRGB), and the DPI is written as a print-size tag that changes no pixels.
The output is always 8-bit and single-page, one file per PNG. To go back to a web-friendly format, use the TIFF to PNG converter. For photographs that must be small rather than exact, the PNG to JPG converter is the better fit.
Table of Use: PNG to TIFF settings for common jobs
| Job | Setting | What you get |
|---|---|---|
| Artwork for a print shop that asks for TIFF | LZW, DPI 300 | Lossless .tif tagged for 300 pixels per inch; pixel count unchanged |
| Archive or document-system master | ZIP / Deflate or LZW | Lossless TIFF; ZIP is usually the smaller of the two |
| Old software that reads only basic TIFF | None, or LZW | None is the simplest file but the largest; try LZW first |
| Logo or cut-out with transparency | Any compression | RGB + alpha, 8-bit, with straight alpha as in the PNG |
| Wide-gamut screenshot with a colour profile | Any compression | The card adds "ICC profile kept"; the profile is embedded in the TIFF |
| 16-bit PNG | Any compression | 8-bit TIFF; an amber note says each channel was rounded to 256 levels |
| A batch of PNG files | Add them all, then Download All (ZIP) | converted-tiff.zip; duplicate names become scan.tif and scan-2.tif |
DPI only decides the printed size: width in inches = width in pixels / DPI. A 3000 x 2000 pixel image prints 10 x 6.67 inches at 300 DPI and 20 x 13.33 inches at 150 DPI, and a 2550 x 3300 pixel image fills a US Letter page at 300 DPI. If the pixel count is wrong for your print size, change it first with the image resizer.
Features
- Three lossless compression types. LZW is the default; ZIP / Deflate and None are the alternatives. LZW and ZIP both use TIFF Predictor 2 (horizontal differencing) for smaller files.
- DPI from 1 to 10,000. Presets are 72, 96, 150, 300 and 600, or type any whole number. It is stored in inches and never resamples the image.
- Exact PNG values. A full PNG decoder reads the file instead of a canvas, because a canvas rounds the colour of semi-transparent pixels.
- Smallest lossless layout. Opaque grey images become Greyscale, opaque colour images RGB, and anything with transparency RGB + alpha. A colour PNG with an RGB colour profile stays RGB even when every pixel is grey, so the profile still fits. Each card names the layout.
- ICC profile copied. The profile in the PNG is embedded in the TIFF. The exception is a greyscale PNG with transparency: a grey profile cannot describe its RGB + alpha TIFF, so the colours are converted to sRGB exactly as your browser shows them. Gamma and chromaticity chunks and text comments are not copied.
- Orientation handled. If your browser rotates a PNG by its EXIF orientation, the TIFF is written upright.
- Batch queue. Files convert one after another, a setting change converts all of them again, and Download All (ZIP) stays disabled while any file is converting.
Not included: multi-page TIFF, JPEG-compressed TIFF, CMYK, 16-bit output and GeoTIFF. The three compression types compare like this:
| Compression | Lossless | Typical size | Compatibility |
|---|---|---|---|
| LZW | Yes | Small to medium | Read by almost every TIFF program |
| ZIP / Deflate | Yes | Usually the smallest | Current editors and libtiff-based software; some older systems cannot read it |
| None | Yes | Largest: width x height x channels bytes | Simplest possible file |
A TIFF can be several times the size of its PNG. If the aim is simply a lighter file, the image compressor or the PNG to WebP converter do that job.
How to convert PNG to TIFF, step by step
- Under Conversion Settings, choose a Compression: LZW, ZIP / Deflate or None.
- Set the DPI (print resolution tag) from the preset list, or type any whole number from 1 to 10,000 in the box beside it; the list then shows Custom for non-preset values.
- Drop PNG files on the dashed area or click Select PNG Files. Add PNG Files appears once the list has entries.
- Wait for each card under TIFF Files to show its TIFF size, its layout (for example RGB + alpha, 8-bit) and the percentage smaller or larger.
- Click Download on a card, or Download All (ZIP) to get converted-tiff.zip. Clear All empties the list.
Prepare the picture first if it needs it: straighten a sideways scan with the image rotator, trim margins with the image cropper, or turn a BMP source into PNG with the BMP to PNG converter.
Who can use it
- Designers and marketers sending web graphics to a commercial printer that wants TIFF.
- Archivists and records teams adding PNG captures to a repository whose policy names TIFF.
- Authors, publishers and office staff preparing figures at a stated resolution or feeding a document system that accepts only TIFF.
- Developers and testers who need sample TIFFs with known compression, such as LZW or ZIP, to exercise a reader or importer. For another legacy format, see the PNG to BMP converter.
FAQs
How do I convert PNG to TIFF?
Choose a Compression type and a DPI value, then drop your PNG files on the dashed upload area or click Select PNG Files. Each file is converted in your browser straight away. Download the .tif files one at a time, or click Download All (ZIP). Changing the compression or DPI afterwards converts every file again with the new setting.
Does converting PNG to TIFF lose quality?
No. LZW, ZIP and uncompressed TIFF are all lossless, and the PNG is read with a real PNG decoder rather than through a browser canvas, so each 8-bit value is written exactly as the PNG stores it. There are two exceptions. A 16-bit PNG is rounded to 256 levels per channel, because the TIFF is 8-bit, and the card warns you. A greyscale PNG with both transparency and a grey colour profile is converted to sRGB, because that profile cannot describe an RGB + alpha TIFF; its card says sRGB as your browser shows it.
Should I choose LZW, ZIP or no compression?
LZW is the default and the safest choice: it is lossless and the most widely readable. ZIP (Deflate) is also lossless and usually gives smaller files, but a few older or specialised programs read only LZW or uncompressed TIFF. Pick None only when a system demands it, because the file then holds the full pixel data. If unsure, keep LZW.
What DPI should I set when converting PNG to TIFF?
Use 300 for most professional printing, 150 for draft prints and 600 for line art. DPI is only a tag that tells layout software how large to print the image; it adds and removes no pixels. Printed width in inches is pixel width divided by DPI, so 3000 pixels at 300 DPI prints 10 inches wide.
Does PNG to TIFF keep transparency?
Yes. A PNG with transparent or semi-transparent pixels becomes an RGB TIFF with an alpha channel, tagged as unassociated (straight) alpha, the way PNG stores it. Fully opaque images are saved as plain RGB, and opaque grey images as single-channel greyscale (unless an RGB colour profile needs RGB), so no space is spent on channels that carry no information.
Why is my TIFF larger than the PNG?
A TIFF applies one predictor to the whole image, while a PNG can choose a filter for every row, so a well-optimised PNG is often smaller than the same pixels in a compressed TIFF. An uncompressed TIFF is width x height x channels in bytes: 2000 x 1500 RGB is 9,000,000 bytes. Each card shows both sizes and the percentage difference.
Is it safe to convert PNG to TIFF online? Are my files uploaded?
Nothing is uploaded. The PNG is decoded and the TIFF is written by code running in your browser tab, a WebAssembly PNG decoder plus JavaScript, and then saved straight to your downloads. You can check the Network tab in DevTools while converting: no request carries your image. Nothing is sent to ZipConvert or anyone else.
Why does the preview show my PNG and not the TIFF?
Most web browsers cannot display TIFF files, so each card previews the source PNG and labels it Source PNG. The TIFF itself is built correctly and downloads as a .tif file. Open it in an image editor, a print or layout program, or an image viewer that supports TIFF, such as Preview on a Mac.
