TIFF to PNG Converter
Drop TIFF files, get lossless PNGs back — 100% in your browser. No uploads, no accounts, no limits. Batch convert, multi-page TIFFs, every page as its own PNG.

Scans and print files saved as TIFF are pixel-perfect but huge — and many apps, forms and the web only accept PNG. PNG is lossless, so nothing is thrown away, and it keeps transparency — but the files are usually larger than JPGs.

How to convert TIFF to PNG without uploading it
- Drop your TIFF files above — or paste one straight from your clipboard. You can add up to 20 at once.
- Pick an output width (800 px is a good default for the web; Original keeps every pixel). PNG is lossless, so there is no quality setting to choose. Multi-page TIFFs become one PNG per page, numbered in order.
- Download each page, or grab everything as one ZIP. Your originals are untouched and your file data never leaves your device.
Why convert TIFF to PNG at all?
TIFF is the format scanners, cameras and print shops use because it keeps every pixel — but that makes files huge, and many upload forms, email clients, messaging apps, websites and older programs only accept PNG. PNG is the lossless web format: it keeps every pixel exactly, and it keeps transparency, so a scanned document, diagram or logo converts without the artefacts JPG would add. For photos where smallest size matters more than pixel-perfect quality, JPG is the better choice — this converter is for when nothing may be lost.
Honest limitations
- PNG is lossless — but usually larger than a JPG of the same image. If smallest size matters more than pixel-perfect quality, convert to JPG instead.
- 16-bit TIFFs are tone-mapped to 8-bit — PNG only stores 8 bits per channel, so the extra depth is gone. On a standard display the result looks the same, but keep the original if you need the depth.
- CMYK TIFFs use a simple conversion — the decoder converts CMYK to RGB without a colour profile, so colours can shift slightly compared with a colour-managed application. The tool tells you on the file when it happened.
- JPEG-compressed TIFFs are untested with this decoder — the old JPEG-in-TIFF flavour may fail or decode wrongly. Convert the source to an uncompressed or LZW TIFF first if it does.
- TIFF orientation tags are read and reported but NOT applied — a sideways scan stays sideways. Rotate it in an editor first if that matters.
- TIFFs with large flat areas may not shrink much — scanned documents and line art already compress extremely well, so the PNG can come out larger. The tool says so on the file instead of hiding it.
- EXIF metadata is dropped on re-encode — keep the original if you need camera or scan settings.
- Estimates are estimates — the size shown while converting is a rough model; the real size is shown once conversion finishes.
Frequently asked questions
How can I convert TIFF to PNG without uploading it anywhere?
This converter runs entirely in your browser: it decodes your TIFF with a TIFF decoder running on your device and re-encodes it as PNG on a canvas. Your file data never leaves your device — the only third-party requests are the site's own analytics, which load at page open and never see your files. Verify it in the Network tab while it works.
What happens to a multi-page TIFF?
Each page becomes its own PNG, named after the original file with the page number added — for example scan.tif becomes scan-page-01.png, scan-page-02.png, and so on. You can download pages one by one or grab them all in a single ZIP.
Which TIFF files can this converter open?
Uncompressed, LZW, Deflate and PackBits TIFFs in 8-bit RGB or greyscale, including multi-page files. 16-bit TIFFs are accepted and tone-mapped to 8-bit, which looks the same on a standard display. CMYK TIFFs are converted with a simple profile-free conversion, so colours may differ slightly from a colour-managed application. JPEG-compressed TIFFs are untested with this decoder. Files that are not really TIFFs — a JPEG renamed to .tif, for example — are refused with a message naming the real format.
Does converting TIFF to PNG lose quality?
No — PNG is lossless, so every pixel of the decoded image survives exactly. There is no quality slider because there is nothing to trade off. The price is file size: a PNG is usually much larger than a JPG of the same image, so keep the original TIFF as your master copy and use JPG when smallest size matters more than pixel-perfect quality.
What happens to 16-bit TIFFs and CMYK TIFFs?
PNG only stores 8 bits per channel, so a 16-bit TIFF is tone-mapped to 8-bit — the difference is imperceptible on a standard display, but the extra depth is gone, so keep the original if you need it. CMYK TIFFs are converted with a simple profile-free conversion rather than a colour-managed one, so colours can shift slightly; the tool tells you on the file when it happened.
Does the PNG keep transparency?
Yes. PNG stores an alpha channel, so transparent areas in the TIFF stay transparent in the PNG — the preview shows them against a checkerboard so you can see it. A JPG of the same image would flatten transparency onto a solid colour, which is one reason to choose PNG.
Why is my PNG larger than the original TIFF?
TIFFs with large flat areas — scanned documents, line art, diagrams — already compress extremely well, so PNG has nothing to gain and can come out larger. PNG also keeps every pixel exactly, while JPG throws detail away to shrink. The tool tells you honestly on each file when the PNG is larger.
Is there a file size or daily limit?
No daily limit, no account. A 25 MB cap per file and 20 files per batch apply, because browsers cannot safely hold larger images in memory. Very large TIFFs are also limited to 50 megapixels for the same reason.
Does converting strip EXIF data or change orientation?
Re-encoding drops EXIF metadata (camera settings, location, scan settings) — keep the original if you need it. TIFF orientation tags are read and reported but NOT applied, so a sideways scan stays sideways; rotate it in an editor first if that matters.
How do I verify my files really never upload?
Open developer tools (F12), go to the Network tab, then convert a file. Your file data never leaves your device — the only third-party requests are the site's own analytics, which load at page open and never see your files. The live counter above shows the same number.
