Convert TIFF to PNG Online
Upload a TIFF and get back a PNG whose pixels are stored losslessly, with any alpha channel carried over. One thing to know first: if your TIFF holds several pages, only the first one is converted.

Why convert TIFF to PNG
TIFF is less a single format than a container with decades of options inside it: LZW, JPEG or uncompressed data, CMYK or RGB or grayscale, 8-bit or 16-bit channels, one page or a stack of scans, with or without an alpha channel. That flexibility is why scanners, microscopes and prepress shops all write TIFF, and it is also why a TIFF will not display in a browser tab or in most web uploaders. PNG is the opposite: one well-defined RGB/RGBA structure that every browser, editor and platform reads. So this is the conversion you want when a scanned receipt, a logo saved out of a print layout or a lab image has to go somewhere that only takes PNG, and anyone searching for TIFF to PNG with a transparent background is in the right place too, because an alpha channel that already exists in the TIFF survives.
Here the TIFF is decoded by libvips (through sharp) first. The pixels are auto-oriented, then written as PNG with zlib compression level 6 and the alpha channel kept intact. PNG compression is lossless, so the pixel values that come out of the decoder are the values stored in the file, with no quality setting and no generation loss. When libvips cannot read a particular TIFF variant, ImageMagick takes over as a second decoder, which is what handles CMYK TIFFs, older LZW layouts and JPEG-2000-in-TIFF files; that path also keeps alpha.
Some things change on the way out, and it is better to know than to be surprised. A 16-bit-per-channel TIFF read by libvips, the kind a film or flatbed scanner produces, is written as an 8-bit PNG. A CMYK or Adobe RGB TIFF is converted to sRGB, so colors can shift slightly compared with a prepress proof. EXIF and ICC profiles are not written into the PNG on the libvips path, indexed-color TIFFs are written out as ordinary RGB PNG rather than a palette PNG, and a multi-page TIFF yields one PNG from page 1 only.
How to convert a TIFF file to PNG
- Check the TIFF first. If it is a multi-page scan and you need every page, split it in an editor (or export each page separately) before uploading, because the converter takes page 1.
- Drop the .tif or .tiff file onto the upload area. Both extensions are treated the same. Without an account a file can be up to 50 MB; a free account raises that to 100 MB, and up to 10 files can go in one batch.
- Start the conversion. The file is uploaded to our servers and converted there in a worker process, not in your browser. Small TIFFs like a page scan usually finish within a few seconds of the upload completing.
- Download the PNG. Each input gets its own PNG file, and the download link stays valid for about four hours.
- Open it and check two things if the source was a high-end scan: that the transparency looks the way you expect, and that the 8-bit color is acceptable for your use.
What this converter does
- Writes lossless PNG: pixel data is compressed with zlib at level 6, with no quality slider to lose detail to.
- Keeps an existing alpha channel, so logos and cutouts stay transparent instead of being flattened onto white.
- Two decoders behind the page: libvips for ordinary RGB and grayscale TIFFs, ImageMagick as fallback for CMYK, older LZW and JPEG-2000 TIFF variants.
- Auto-orients the image, so a TIFF carrying a rotation tag comes out upright rather than sideways.
- Accepts .tif and .tiff equally, plus palette, grayscale, 16-bit and alpha TIFFs, converting them all to standard 8-bit RGB or RGBA PNG.
- Runs on our servers with nothing to install and no sign-up needed for files under 50 MB; up to 10 TIFFs can be queued in one batch.

TIFF to PNG questions
Is TIFF to PNG conversion lossless, without losing quality?
The compression itself is lossless: PNG stores exact pixel values, so for a plain 8-bit RGB or grayscale TIFF the PNG matches the source pixel for pixel. Two honest caveats: a 16-bit TIFF read by libvips is written as 8-bit, and a CMYK or Adobe RGB TIFF is converted to sRGB, which can shift colors slightly.
Will a transparent background survive the conversion?
Yes, if the TIFF actually has an alpha channel. Both decoder paths carry alpha into the PNG. If the TIFF has no alpha, a transparent background cannot be created here; you would need to cut out the background in an image editor first, then convert.
My TIFF has several pages. Will I get a PNG for each one?
No. Only the first page is converted; the rest are ignored, and there is no page-range option. If you need every page, export the pages individually from an editor or a multi-page TIFF splitter and upload them as a batch of up to 10 files.
The conversion failed with "ImageMagick conversion failed (The file may be corrupt or unsupported)". What now?
That message means neither decoder could read the file: usually a truncated download, an unusual compression scheme inside the TIFF, or a file renamed to .tif that is not a TIFF. Open it in an image editor and re-export it as a plain uncompressed or LZW TIFF, or save it as PNG directly from that editor.
Can I choose the resolution, DPI or compression level?
No. This page has no settings; it decodes the TIFF and writes PNG at a fixed compression level, at the TIFF's own pixel dimensions. If you need smaller pixel dimensions, use the resize-image tool on the PNG afterward (it works on one file at a time and never enlarges).
Can I convert many TIFFs at once, or use Python instead?
Up to 10 TIFFs go in one batch and each PNG is downloaded individually, since there is no zip-all button. For hundreds of files a local Pillow script is more practical, and on macOS Preview can export a TIFF to PNG with no upload at all.
What happens to my file after the conversion?
The TIFF is uploaded to our servers over HTTPS, converted there, and deleted as soon as the job finishes; the PNG and its download link are removed automatically after about four hours. File names, sizes and outcomes are logged for operations, and signed-in users also get a row in their conversion history.
Should I pick PNG, or is JPG better for my scan?
PNG is the right choice for line art, screenshots, logos, text scans and anything needing transparency, because nothing is smoothed away. For a continuous-tone photograph scan where file size matters, our TIFF to JPG page gives a much smaller file at similar apparent quality.
