Convert PNG to TIFF
PNG and TIFF can both store exact pixels, but they belong to different working habits. PNG is the convenient exchange format for screens and graphics; TIFF is the roomy, well-documented container that scanners, archives, and image editors have trusted for decades. This conversion changes the container without adding detail, and that distinction matters when a TIFF requirement is really a request for a durable editing master.

- No watermark and no sign-up
How to use PNG to TIFF
- 1
Add the PNG
Choose the original PNG rather than a screenshot or a copy that has already been resized. A PNG contains one image, so this page accepts one still image and will create one TIFF image from it.
- 2
Convert to TIFF
The file is decoded and its pixels are written into a TIFF on our server. Because the output is lossless, the download can be much larger than the upload even when the image looks exactly the same.

Check the workflow requirement
Open the result in the editor or archive system that requested TIFF. Confirm color mode, resolution metadata, compression preference, and file size too; changing the extension alone does not satisfy those separate requirements.
How it works
The PNG is decoded into image pixels and those pixels are encoded as a TIFF. The conversion is not an enlargement, restoration, or color correction step. It is a change of container and a change of the way the image is packaged for the next piece of software in the workflow.
That makes the result lossless in the useful, forward-looking sense: opening and resaving the TIFF does not have to discard another generation of pixels. It does not make the original PNG more detailed. If the PNG came from a lossy source, its artifacts are already part of the pixels and will be preserved faithfully.
Why TIFF is useful for archives
An archive wants a format that can be documented, validated, migrated, and opened by more than one generation of software. TIFF has a long history in scanning, publishing, microscopy, and cultural-heritage workflows. Its structure can hold different color depths, alpha channels, metadata, and compression choices without forcing every use case into one web-oriented profile.
That flexibility is also why an archive's TIFF specification needs to be read carefully. “TIFF” may be followed by requirements for 8-bit or 16-bit channels, RGB or CMYK, a color profile, 300 dpi metadata, or LZW compression. This page changes the file format, but it does not turn RGB into CMYK, add a profile, or invent a higher bit depth. Treat those as decisions for the imaging workflow.
Editing without another generation loss
TIFF is a sensible working copy when an editor or print process expects it. A PNG can also be edited losslessly, but TIFF is more widely used for large raster masters and can accommodate the conventions of prepress and scanning applications. Keep the original PNG as well: converting is not a reason to throw away the source, and the source may be more convenient for a website or a lightweight handoff.
The practical limit is storage and transport. A lossless TIFF can be many times the size of a PNG, so a large scan may hit upload, download, email, or application size limits even though the pixels are valid. TIFF itself can describe very large images, but a particular reader, archive intake form, or server may impose a smaller limit. Check the destination rather than treating the format name as a guarantee.
The multipage boundary
TIFF can represent multiple pages, but that capability does not mean every TIFF conversion creates them. This route receives one PNG and produces one still. For a scanned packet, first obtain one image per page, then use a tool that explicitly assembles and orders a multipage TIFF. That distinction prevents a common mistake: assuming a single image file can somehow carry pages that do not exist in its input.
Examples
A scan being placed in an archive
The output is larger because it keeps the decoded pixels in a format the archive can inspect and reprocess later. It does not recover detail beyond what was already present in the PNG, but it meets a TIFF intake requirement.
A transparent illustration for editing
The editor receives the same canvas and alpha information in a container designed for repeated saves. The increase in storage is the tradeoff for a lossless working file, not evidence that the illustration became sharper.
Frequently asked questions
Does converting PNG to TIFF improve image quality?
No. PNG already stores its image losslessly, so the TIFF receives the same decoded pixels rather than a sharper or higher-resolution version. The useful change is workflow compatibility: a scanner archive or professional editor may accept TIFF features and conventions that a PNG-based process does not. Any blur, missing detail, or small dimensions in the source remain unchanged.
Why is the TIFF file larger than the PNG?
TIFF is a flexible container, and lossless TIFF storage often compresses a graphic less efficiently than PNG, especially when the image contains large photographic areas or noisy scans. A larger file is normal here. It is not a conversion error, and it does not mean extra pixels were invented. If an archive specifies LZW or ZIP compression, that is a separate TIFF setting.
Can this create a multi-page TIFF from a PNG?
No. A PNG is a single-image source and this page writes one TIFF image for that source. TIFF as a format can hold multiple pages or frames, which is why it is common for document scans, but creating such a file requires a sequence of images and an explicit page-order workflow. Convert or merge those pages with a multipage tool instead of expecting one PNG to supply them.
