Check it yourself
Your images never leave this tab.
Open your browser's developer tools, switch to the Network tab, and convert a file. You will see the encoder and its WebAssembly module load from this domain the first time, and then nothing — no upload, no image data, no request carrying your file anywhere. Turn off your Wi-Fi after the page loads and it still works.
The lossless path out of TIFF
TIFF is the format scanners, archives and print shops have used since 1986, and for good reason: it stores images without throwing anything away. The trouble is that nothing on the web can read it. No browser displays TIFF, and most upload forms reject the extension.
PNG is the natural destination when you want out of TIFF without giving anything up. It is also lossless, so every pixel transfers exactly — you are changing the container, not the image.
How to convert TIFF to PNG
- Drop your
.tifor.tifffiles onto the box above, click it to browse, or drop a folder of scans. - PNG is already selected as the output format on this page.
- Press Convert, then download the files individually or as a single ZIP.
There is no quality slider on this page. PNG has no lossy mode, so there is nothing to set and nothing to get wrong.
PNG or JPG for a scan?
This is the decision that actually matters, and it depends entirely on what was on the paper.
Choose PNG for text, forms, contracts, line drawings, engineering plans, sheet music — anything built from hard edges. JPEG compression puts a faint halo around the boundary between black ink and white paper, and on small type that reads as muddiness. Lossless keeps it sharp.
Choose JPG for photographs and artwork. A continuous-tone image compresses beautifully as JPEG and terribly as PNG — the same scan can easily be twenty times larger as a PNG for no visible benefit.
Only the first page is converted
Worth knowing before you queue up a stack. A TIFF file can hold many images, and multi-page TIFFs are the norm for scanned documents. This converter decodes the first image and writes one PNG from it; the remaining pages are not written. For single-page scans that is invisible. For a bound document scanned into one file, split it first.
What does not carry across
Pixels survive intact. Metadata largely does not — embedded ICC colour profiles, DPI resolution tags and scanner annotations are TIFF strengths that PNG either cannot store or does not store here. If a print workflow depends on the embedded profile, keep the TIFF as your master and treat the PNG as a derivative.
Nothing is uploaded
The TIFF decoder and the PNG encoder are both WebAssembly modules running in this browser tab. Your scans are never transmitted anywhere. For medical imaging, legal discovery and archival material — the things TIFF is actually used for — that is the whole reason to use a tool like this one rather than a service that wants the file on its server first.
Frequently asked questions
- How do I convert TIFF to PNG for free?
- Drop your .tif or .tiff files onto the box at the top of this page — PNG is already selected — press Convert, and download the results. No account, no watermark and no daily limit, because the decoding and encoding both run on your own machine.
- Why can't my browser display a TIFF?
- No major browser has ever supported it. TIFF was built in the 1980s for scanners and desktop publishing, and it is really a container that can hold many different compression schemes rather than one format. This site ships its own TIFF decoder compiled to WebAssembly, which is how it reads files the browser will not.
- Is anything lost in the conversion?
- No pixels are lost. Both formats are lossless, so the image data transfers exactly. What does not transfer is the surrounding metadata TIFF is good at carrying — embedded colour profiles, DPI tags and scanner annotations do not survive into the PNG.
- What happens to a multi-page TIFF?
- Only the first page is converted. TIFF is the standard format for multi-page scans and fax archives, but this converter reads the first image in the file and writes a single PNG. Split the TIFF in a desktop tool if you need every page.
- Should I convert my scan to PNG or JPG?
- PNG when the page is text, a form, a line drawing or an engineering plan — it is lossless, so the hard black-on-white edges that make text legible stay crisp. JPG when the scan is a photograph or artwork, where the file will be far smaller and the compression suits continuous tone.
- Will the PNG be smaller than the TIFF?
- Usually yes, sometimes by a lot. TIFFs are often stored uncompressed, and PNG always applies lossless compression — so a scan of a mostly-white document page can shrink enormously with nothing at all given up. A TIFF that already used LZW compression will see a more modest gain.
- Is there a size limit?
- No. Decoding happens in your browser, so the practical limit is your machine's memory rather than an upload cap. Large high-DPI scans work; they simply take a moment.
- Are my scans uploaded?
- No, and there is nowhere for them to go — this is a static site with no upload endpoint. The scans never leave your machine, which matters given that TIFF is the format of choice for legal, medical and archival documents.
Other conversions
Each converter opens with the right output format already selected, so the file you drop comes back in the format you came for.
Convert WebP to another format
Convert images to WebP
- Convert PNG to WebP Keep the transparency, drop most of the file size. Lossless mode is one click away if you need pixel-exact output.
- Convert JPG to WebP Typically 25-50% smaller than the same photo as a JPEG, at a quality most people cannot tell apart.
- Convert JPEG to WebP The same conversion as JPG — the two extensions are one format. Smaller files, same picture.
- Convert HEIC to WebP iPhone photos, converted in the browser. No app, no upload, and it works on iOS Safari where most converters do not.
- Convert AVIF to WebP Usually a compatibility move rather than a size one. WebP opens in more places than AVIF still does.
- Convert GIF to WebP Static GIFs convert cleanly and shrink hard. Animated GIFs convert to their first frame — and we will tell you when that happens.
- Convert TIFF to WebP Scans and print files, converted to something a browser can actually display.
- Convert BMP to WebP BMP stores pixels essentially uncompressed. Expect the file to get very substantially smaller.
- Convert SVG to WebP Turning vector into pixels. You choose the size, because a vector does not really have one.
Convert to PNG or JPG
- Convert HEIC to JPG Turn the photos your iPhone actually shot into the format everything else can open. The pictures never leave your device.
- Convert HEIC to PNG Convert iPhone photos into PNG when the software you are feeding demands it. Lossless, private, and free.
- Convert SVG to PNG Rasterize vector artwork into PNG at the exact size you need, with the transparent background intact.
- Convert SVG to JPG Rasterize vector artwork into JPG for the places that will not take anything else. Free, unlimited, nothing uploaded.
- Convert TIFF to JPG Turn enormous archival scans into files you can actually email. Free, unlimited, and nothing leaves your machine.
- Convert AVIF to JPG You downloaded an AVIF and nothing on your computer will open it. This turns it into a JPG that everything opens.
- Convert AVIF to PNG Convert AVIF into PNG for the software that has never heard of AVIF. Transparency intact, nothing uploaded.
- Convert GIF to PNG Convert GIF into PNG without losing a pixel — and escape the 256-colour palette for good.
- Convert GIF to JPG Convert GIF into JPG for the systems that insist on it. Free, unlimited, and nothing leaves your machine.
- Convert BMP to PNG Shrink uncompressed Windows bitmaps dramatically without losing a single pixel. Free, unlimited, nothing uploaded.
- Convert BMP to JPG Turn enormous uncompressed bitmaps into files you can actually send. Free, unlimited, and nothing leaves your machine.
