Convert TIFF to PNG Online
Open TIFF scans and print files in any browser, then export them as lossless PNG. No image viewer, no plugin, and no upload, since decoding happens entirely on your device.
How to Convert TIFF to PNG in Three Steps
Select a TIFF or multi-page TIFF file, wait while the browser decoder loads, then download a PNG you can open anywhere.
Step 1
Choose TIFF
Add a TIFF or TIF file exported from a scanner or print workflow.
Step 2
Auto Decode
The browser loads a decoder and reads the TIFF without any server.
Step 3
Download PNG
Save the PNG result and open it in virtually any application.
Why Convert TIFF to PNG — Open Print And Scan Files Without Specialized Software
TIFF is the format the print, publishing and archival worlds settled on, and for good reason. It handles very high bit depths, CMYK colour separations, layers and multiple pages in a single file, all without lossy compression. That power is exactly why browsers cannot open it natively, and why someone who receives a TIFF from a scanner, a printer or an archive often just wants to look at the thing and send it on. Being unable to open a file a client sent you is a small problem that becomes a large one on a deadline.
Since browsers ship without a TIFF decoder, this tool loads UTIF, a JavaScript TIFF library, from a content delivery network the first time you convert a TIFF file. It runs on your own machine, decodes the image to RGBA pixel data, and the result is drawn onto a canvas and re-encoded as a PNG. Expect the first conversion to pause briefly while the decoder downloads; afterwards it is cached and subsequent files process quickly. The decoding happens entirely on your own processor, so the image itself is never handed to anyone else.
One limitation deserves stating plainly. A multi-page TIFF produces a PNG of the first page rather than a separate file for every page. For single-page scans and exports, which is what most people are converting, this makes no difference whatsoever, but it is worth knowing before you feed in a forty-page document. Single-page scans, which cover the overwhelming majority of real conversions, are entirely unaffected.
You should also understand what happens to exotic colour data. Very high bit-depth sources and CMYK separations are flattened to standard RGBA, because that is what a browser canvas can represent. The PNG you get is therefore an excellent viewing, sharing and delivery copy, but it is not a faithful archival substitute for the original TIFF. Keep the source file if the colour data matters downstream. For viewing, sharing and delivery, the flattened PNG is indistinguishable in practice and far more portable.
What you gain is substantial: a lossless file that opens in any browser, image viewer or editor, and that you can email, upload or share without the recipient installing anything. Typical situations include receiving scans from a printer or a client, submitting documents to portals that reject TIFF, sharing archive images with colleagues, and previewing files without installing a viewer. Nothing is uploaded, no account is needed, and no watermark is added. Batch conversion and a single ZIP export make a folder of scans a one-pass job.

FAQ
Frequently Asked Questions
TIFF is a highly capable print and archival format supporting CMYK, very high bit depths, layers and multiple pages. Browsers never shipped a decoder for it, because that complexity is unnecessary on the web. Converting to PNG lets you view and share the image anywhere without installing specialist software.
No. The UTIF decoder is fetched once from a content delivery network and then runs entirely on your machine. Your file is decoded locally, drawn onto a canvas and encoded as PNG without any image data leaving your device. Nothing is stored afterwards.
Because browsers cannot decode TIFF natively, the tool downloads the UTIF JavaScript library the first time you convert a TIFF file. Once your browser has cached it, every subsequent file in the same session converts quickly, so the brief pause only happens once.
The converter produces a PNG of the first page. It does not split a multi-page document into separate image files. For single-page scans and exports this is irrelevant, but if you need every page saved individually, use a dedicated TIFF splitting tool.
The PNG encoding step itself is fully lossless. However, very high bit-depth and CMYK sources are flattened to standard RGBA, because that is what a browser canvas can hold. Treat the PNG as an excellent viewing and delivery copy rather than an archival replacement for the original TIFF.
Yes. Add multiple TIFF or TIF files and each is decoded and converted in the same session. Download each PNG individually or export the complete set as a single ZIP archive, which is the fastest way to handle a batch of scanner exports or archive files.
They are accepted and decoded, but the colour data is flattened to standard eight-bit RGBA for the canvas, since that is all a browser can represent. The resulting PNG is perfectly usable for viewing and sharing, but keep the original TIFF whenever colour separations or bit depth matter downstream.
Yes. There is no registration, no email requirement, no daily conversion quota and no premium tier. Convert a single scan or an entire archive under identical terms, and every PNG you download is clean with no watermark or branding applied.
Yes. The two extensions refer to the same format and the converter accepts both without distinction. Whether your file came from a scanner, a printer, a camera or an archive system, either extension is decoded the same way and exported as PNG.
Open this page in Chrome, Edge, or Safari, drop your TIFF files in, and download the PNGs. The TIFF decoder runs as WebAssembly inside the tab, so you never need a desktop viewer, a Photoshop licence, or a system-level plugin.
