Convert PNG to TIFF Online
This page turns your PNG into a .tif file for the print shops, scanning systems and document portals that ask for TIFF. Read the quality note first: the TIFF we write uses JPEG compression and drops the alpha channel, so transparent areas come out black and the result is not a lossless archive copy of your PNG.

What a PNG to TIFF Conversion Really Gives You
PNG and TIFF both store pixels without a visible quality loss in principle, so people rarely convert between them for picture reasons. The reason is almost always a receiving system: a prepress operator who only takes .tif, a document management or OCR intake that rejects PNG, a GIS or imaging package that reads TIFF and nothing else, or a submission form that lists TIFF as the required format. TIFF has been around since 1986 and is the format those workflows standardized on.
Here is exactly what happens on our servers. The PNG is decoded with sharp, built on libvips, auto-oriented, and written out as a TIFF. That TIFF is produced with sharp's default encoder settings, which means the pixel data inside is JPEG-compressed at about quality 80, stored as 8-bit YCbCr, and the alpha channel is discarded. Transparent regions of your PNG become black, not white and not transparent. We do not currently offer LZW, Deflate or uncompressed TIFF output, and there is no option to change the compression or quality.
So the honest summary: this is a container change with a quality cost, not an upgrade. If your PNG is an opaque photo or a flat screenshot and the destination simply demands a .tif file, the output will look fine; if you need a lossless master, or a TIFF that keeps transparency or 16-bit depth, keep the PNG as your archive copy or write the TIFF in a desktop editor where you can pick LZW or Deflate and store an alpha channel.
A few other things to expect. A 16-bit PNG is written out as 8 bits per channel. Palette PNGs become full-colour. An animated PNG contributes only its first frame. We write no EXIF and no ICC profile into the TIFF, and wide-gamut source data is converted to sRGB. Pixel dimensions are never changed: there is no resampling, no upscaling and no DPI control on this page, which is why the searches for a 300 or 600 dpi TIFF cannot be satisfied here.
How to Convert PNG to TIFF
- Decide whether lossy is acceptable. For a print proof or a form upload it usually is; for an archival master it is not, and you should keep the PNG instead.
- If your PNG has transparency, flatten it onto the background colour you want in an image editor before uploading. Otherwise those pixels will be black in the TIFF.
- Add your PNG files on this page. Up to 10 per request as a guest, at 50 MB each; a free account lifts the per-file ceiling to 100 MB, and very large pixel dimensions over roughly 268 megapixels are rejected.
- Run the conversion. Small and medium files are normally done a few seconds after the upload completes, and each PNG produces its own .tif file.
- Download the results within about four hours, then open one in your target application to confirm the colours and edges are what the recipient needs.
Capabilities and Limits
- Reads 8-bit and 16-bit PNG, palette PNG and PNG with alpha, using sharp and libvips on our servers
- Writes a JPEG-compressed TIFF (8-bit YCbCr) that mainstream editors and viewers such as Photoshop, Preview and ImageMagick read directly
- Keeps the exact pixel width and height of the source; no resampling or cropping
- Applies any orientation flag so the TIFF is stored the way the image is displayed
- Converts several PNGs in one request, each downloaded as a separate .tif
- No install and no sign-up: the work happens server-side after upload

PNG to TIFF: Questions We Get
Can I convert PNG to TIFF without losing quality?
Not on this page. Our TIFF output is JPEG-compressed at roughly quality 80, so there is a generational loss, which is most visible on sharp text, line art and large flat colours. For a truly lossless result, keep the PNG, which is already lossless, or write the TIFF in a desktop tool with LZW or Deflate compression.
Can I get a 300 dpi or 600 dpi TIFF?
There is no DPI or resolution setting here, and we do not resample the image. DPI is a number that tells a printer how large to render a fixed grid of pixels, so a 3000-pixel-wide image is a 10-inch print at 300 dpi and a 5-inch print at 600 dpi. If a printer asks for 300 dpi, what they need is enough pixels for the physical size, which means exporting at the right dimensions from the original artwork, then setting the resolution field in your editor.
What happens to my PNG's transparency?
It is lost. The alpha channel is dropped and transparent pixels end up black. If you want white behind a logo, flatten the PNG onto white before uploading. If the transparency itself must survive, keep the PNG or write the TIFF in an editor that lets you store an alpha channel.
Which TIFF compression do you use, and can I pick LZW?
The output uses JPEG compression inside the TIFF container, stored as 8-bit YCbCr. LZW, Deflate, uncompressed and CMYK TIFF are not available as options on this page. A side effect is that the .tif is often smaller than an uncompressed TIFF would be, which can help with portals that have tight size limits.
Will a 16-bit PNG stay 16-bit?
No. The TIFF is written at 8 bits per channel, so a 16-bit PNG loses that extra tonal depth.
Does the TIFF keep the file's metadata?
No EXIF and no ICC profile are written into the TIFF, and non-sRGB source data is converted to sRGB. If a workflow depends on an embedded profile, add it in your editor after conversion.
How many files can I convert, and what are the size limits?
Guests and free accounts convert up to 10 files per request, Plus up to 25 and Pro up to 50. Per-file size is 50 MB for guests, 100 MB with a free account, 200 MB on Plus and 1 GB on Pro. Guest and free usage is also capped at 10 conversion jobs per hour per IP address.
What happens to the files I upload?
Conversion runs on our servers. Your uploaded PNG is deleted as soon as the job ends, and the TIFF can be downloaded for about four hours through a random, unguessable link before it is deleted automatically. File names, sizes and outcomes are recorded in our logs, and signed-in users also get a history entry on their account.
