How to convert TIFF to PNG
- Add your
.tifor.tifffile. Every page gets a thumbnail, so finding the page you want is quick even in a long scan. - Select the pages to export. Picking a few pages is usually what you want — a whole scanned book turns into a lot of image files.
- Press Export PNG.
- One selected page downloads as a single PNG. Two or more come back as a ZIP, with each file named after its page number in the original document.
What each image looks like
Each PNG is a picture of the finished page: the page keeps its proportions, and a page you rotated is exported rotated. Pages of different sizes stay different sizes — nothing is padded or cropped to make them uniform, and a page carrying an orientation tag is turned the right way up first.
PNG stores the rendered page without adding compression artefacts, so black-and-white text pages stay crisp. The trade-off is size: PNG files are larger than photographic formats, and exporting many pages of a scan produces a ZIP noticeably larger than the TIFF you started from.
Which TIFF files work here
The compression types scanners and document systems actually produce are covered: uncompressed, LZW, Deflate, PackBits, CCITT Group 3 and Group 4 fax compression, and JPEG-compressed TIFF. Single-page and multipage files both work, and pages inside one file may differ in size, resolution and colour.
TIFF is an old and very wide format, so some variants fall outside what this tool reads. When that happens the message says which kind of problem it is — an unreadable file, a compression method that isn't supported yet, a variant that isn't supported yet, or a file too large to process safely.
What an image file doesn't carry
A PNG holds pixels and nothing else. If the TIFF came from a scanning workflow that stored text alongside the image, that text is not part of the PNG, and the page tags, resolution metadata and any other TIFF fields are left behind too.
So this is the right tool when you need a page as a picture — to drop into a document, post online or edit. It is the wrong one when what you actually need is the text.
Everything happens on your device
The TIFF decoder runs inside your browser tab and the images are written locally. Nothing is uploaded and there is no account to create.
Pages are only decoded when you actually look at them or export them, so opening a long document stays quick, even on a phone.
Frequently asked questions
Can I get one image per page of a multipage TIFF?
Yes — that is exactly what a multi-page export does. Select the pages you want, export, and the ZIP contains one PNG per page, numbered by its page number in the source document.
Why do I get a ZIP instead of separate downloads?
Because a browser asking to save thirty files one after another is worse than one archive. A single selected page skips the ZIP and downloads as a plain PNG.
Are BigTIFF files supported?
Not yet. BigTIFF is a separate 64-bit variant of the format, and files that use it are refused with a message saying the variant isn't supported rather than being reported as damaged. Older JPEG-compressed TIFF (the pre-1994 'old JPEG' encoding) is not supported either.
Is my file uploaded to convert it?
No. The decoder and the image encoder both run in your browser tab, so the file bytes never leave your device.
