PNG to TIFF Converter

PNG TO TIFF, run entirely on your device with no upload: the converter reads each PNG inside your browser tab and re-encodes it to TIFF locally, so the file is never transmitted to a server. Most people reach this page because a downstream professional workflow demands TIFF specifically, print and prepress shops, legal and medical records archival, photo and film scanning preservation, or software like GIS and OCR pipelines that only ingests TIFF. You need a guaranteed lossless result, transparency intact, and often a batch of many files, without the watermarks, caps, and risky uploads that server tools impose on exactly the sensitive documents headed for TIFF.

What this conversion actually does (and does NOT do)

Both PNG and TIFF are lossless raster formats, so a correct PNG to TIFF conversion loses zero pixel data. This is not a quality-degrading conversion the way PNG to JPG (jpeg) is. It is a lossless-to-lossless re-container: the same pixels move from one wrapper into another. Nothing is approximated, nothing is thrown away.

Expect the file to get bigger, not smaller. TIFF files are typically 2-5x larger than the source PNG even with LZW or Deflate compression, because PNG's DEFLATE filter is more space-efficient than TIFF's compression schemes. This surprises people: a 4 MB PNG can land as a 10-20 MB TIFF. That is normal and is the price of the format, not a bug. If a smaller file is your actual goal, converting to TIFF is the wrong move.

Compression choice matters. None means maximum compatibility and the largest file, LZW is the standard lossless option with the best compatibility, Deflate (also called ZIP) gives the best lossless ratio, and JPEG-in-TIFF is lossy and smallest, which you should avoid for archival. LZW is the safe default for almost every job.

Transparency survives. PNG's alpha channel is preserved because TIFF natively supports an alpha (extra sample) channel, so a transparent PNG yields a transparent TIFF with no flattening needed. Color depth carries over too: an 8-bit PNG maps to an 8-bit TIFF and a 16-bit-per-channel PNG maps to a 16-bit TIFF. Do not downconvert a 16-bit PNG to 8-bit for print or archive, because that discards tonal range you cannot recover. The one thing this conversion does not do on its own is invent capabilities the source lacks: TIFF can hold CMYK, embedded ICC profiles, multiple pages, and CCITT fax compression, but a plain RGB PNG arrives as RGB unless you have those source attributes to carry over.

When to choose PNG to TIFF vs the alternative

Choose TIFF when a downstream tool, printer, or archive mandates it. TIFF is the de facto standard for long-term archival in legal, medical, government, and insurance records, and for high-quality photo and film scanning, which is the main reason this conversion exists. Print and prepress workflows demand TIFF over PNG because TIFF supports CMYK and embedded ICC color profiles that PNG (RGB-only) cannot hold. If instead you just need a smaller or web-deliverable file, keep the PNG, since converting to TIFF only increases size with no visual benefit. To go the other direction once a TIFF needs to live on the web, use the TIFF to PNG converter, and for a JPEG source headed for the same archives, the JPG to TIFF converter covers that path.

How to convert

1. Drop one or many PNG files into the converter; they are read locally in your browser, never uploaded.
2. The output format is pre-selected to TIFF. LZW is the safe lossless default, with Deflate (ZIP) available when you want the tightest lossless ratio.
3. Transparency is carried through automatically, so PNGs with an alpha channel produce TIFF files that keep the same transparency, no flattening.
4. Click Convert. A single file downloads directly; multiple files download together as a ZIP, with no count cap.

No upload. It runs on your device.

The conversion logic is Rust compiled to WebAssembly, and it executes inside your browser tab. There are zero network requests for your file: the PNG bytes go from your disk into memory, through the Wasm encoder, and straight back to a download. After the page loads once, it works offline. There is nothing to delete afterward because nothing was ever uploaded, and you can confirm all of this yourself by watching the DevTools Network tab during a conversion. This is the whole point for the people who convert to TIFF, who are typically handling medical scans, legal records, insurance documents, and government ID images that must never touch a third-party server.

No limits

Unlimited batch conversion, no file-size cap, no daily quota, no watermark on the output, no sign-up, and no ads. Convert one PNG or several hundred in a single pass.

Frequently asked questions

Is converting PNG to TIFF lossless, or will I lose quality?

It is fully lossless, because both PNG and TIFF are lossless raster formats and the conversion just re-containers identical pixels. No quality is lost, unlike PNG to JPG (jpeg) where the image is recompressed and detail is discarded.

Why is my TIFF file bigger than the original PNG?

TIFF files are typically 2-5x larger than the source PNG even with LZW or Deflate compression, because PNG's DEFLATE filter packs pixels more efficiently than TIFF's compression schemes. A size increase is expected and normal, so a 4 MB PNG commonly becomes a 10-20 MB TIFF.

Does PNG to TIFF keep transparency (the alpha channel)?

Yes. TIFF natively supports an alpha (extra sample) channel, so a transparent PNG converts to a transparent TIFF with no flattening onto a background. This is different from converting to JPG, which has no alpha and would fill transparent areas with a solid color.

Which TIFF compression should I choose, None, LZW, ZIP, or JPEG?

LZW is the safe default: standard lossless with the broadest compatibility. None gives maximum compatibility but the largest file, Deflate (ZIP) gives the best lossless ratio, and JPEG-in-TIFF is lossy and smallest, so avoid it for archival work where fidelity matters.

Can I batch convert many PNG files to TIFF at once?

Yes, drop as many PNGs as you like and they are all converted in one pass. A single file downloads directly while multiple files come back as a ZIP, with no file-count cap and no upload bandwidth required.

Is it safe to convert sensitive or medical PNG scans without uploading them?

Yes, because nothing is transmitted: the conversion runs locally in your browser via Rust and WebAssembly with zero network requests for the file. That makes it well suited to medical scans, legal records, and insurance documents, and you can verify the no-upload behavior in the DevTools Network tab.

Does converting to TIFF keep my 16-bit color depth and ICC color profile?

Color depth carries over, so a 16-bit-per-channel PNG maps to a 16-bit TIFF and an 8-bit PNG maps to 8-bit; do not downconvert 16-bit to 8-bit for print or archive because that discards tonal range. TIFF can also hold embedded ICC profiles, which is one reason print and prepress workflows prefer it over RGB-only PNG.

Why would I convert PNG to TIFF instead of just keeping the PNG?

Convert when a downstream tool, printer, or archive mandates TIFF, since it is the de facto standard for legal, medical, government, and insurance records and for high-quality scanning. If you only need a smaller or web-deliverable file there is no reason to convert, because TIFF will be larger with no visual benefit.

Will the TIFF work for professional printing (CMYK)?

TIFF is the format print and prepress shops demand precisely because it supports CMYK and embedded ICC color profiles that PNG cannot hold, since PNG is RGB-only. The resulting TIFF is suitable for that pipeline, though a CMYK separation itself is normally done in your prepress software using the embedded profile.

Can I create a single multi-page TIFF from several PNGs?

TIFF as a format supports multi-page container files, a capability PNG entirely lacks, which is why scanned documents are often stored as one multi-page TIFF. This converter outputs one TIFF per PNG; to combine several images into a single multi-page document instead, the images to PDF tool is the closest local option.
