Open .TIFF files online
A .tiff is a Tag Image File Format image — the format scanners, fax machines, and the publishing world standardized on decades before the web. Drop it on the page and it renders immediately, decoded entirely in your browser: multi-page documents open with page-by-page navigation, and the page on screen exports as a PNG. Nothing is uploaded.
TIFF is also the format browsers famously refuse to render: Chrome, Firefox, and Edge show a blank box where a .tiff should be. A page with its own decoder is the fix — same as this site's HEIC and camera-RAW viewers, the engine runs locally and your image never touches a server.
What is a `.tiff` file?
A TIFF is a container of pages, each described by an IFD (image file directory) listing tags — dimensions, compression, bit depth, resolution — followed by the pixel data. The format (Aldus/Adobe, 1986) supports many compressions: uncompressed, LZW, PackBits, Deflate, CCITT G3/G4 fax coding, and old-style JPEG-in-TIFF, which is why a complete decoder is a real program and browsers never shipped one.
MIME type: image/tiff. Multi-page files chain IFDs one to the next — the structure office scanners mean when they emit a single .tiff per document. The viewer here decodes only the page on screen, so a long scan costs one page of memory at a time.
- Scanner and fax output (often many pages per file)
- Print-shop and DTP interchange (Photoshop layers aside, .tif is the default)
- Archival and document-management systems
- Viewing a format the browser itself cannot display
How to open a `.tiff` online
Open ZipTool in a new tab, then drop your .tiff onto the page — or click to browse for it, or paste a URL. The file opens in the TIFF viewer, page by page for multi-page files, read entirely on your device.
- Drag your
.tiffonto the page — or click to browse, or paste a URL. - It opens immediately in the TIFF viewer, page by page for multi-page files. No install, no sign-up.
- Read, search, or copy it. Your file never leaves your browser.
Open `.tiff` without uploading
Most "open tiff online" sites work by uploading your file to a server and processing it there. ZipTool does the opposite: it loads its parser once, then reads your .tiff locally in the browser tab. The contents stay on your device.
You can prove that in seconds. Open the page, press F12 for DevTools, switch to the Network tab, and open your file — no request carrying the file's contents is sent. You can also turn off Wi-Fi after the page loads and the file still opens. See security and privacy for the full picture.
Frequently asked questions
How do I open a .tiff file online?
Drag the .tiff onto the page (or click to browse, or paste a URL). The first page renders immediately in the TIFF viewer, decoded entirely in your browser. Multi-page files get a page counter with prev/next navigation, and the page on screen downloads as a PNG.
Why doesn’t my .tiff display in Chrome?
Chrome, Firefox, and Edge do not implement TIFF decoding at all — the format predates the web and its many compression variants were never adopted by browsers. The viewer on this page carries its own decoder, so the image renders in any modern browser without an upload.
Can I view every page of a multi-page .tiff?
Yes — the page counter walks the whole document with prev/next, decoding each page on demand. Only the page on screen is decoded at a time, which keeps even a long fax scan light in the browser tab.
Can I download the image as PNG?
Yes — the status bar offers the page you are viewing as a .png, the format every tool accepts. That covers the common “convert this TIFF to something usable” errand for a single page.
Does the viewer show a .tiff's metadata?
When the file carries EXIF — many scanner and camera TIFFs do — an Info panel reads out the device identity (make and model), timestamps, capture settings, and GPS coordinates if present, parsed from the file's own IFD tags locally. Fax-stripped and tool-exported TIFFs carry none, and the viewer shows no panel rather than empty rows — the honest answer about what the file actually contains.
Can ZipTool read the text inside a scanned .tiff?
Yes — scanned documents are what TIFF and OCR are both for. Open the folder holding the file(s) and press “Extract text from images”: each .tiff is decoded and recognized entirely in your browser (a multi-page file contributes its first page), and the extracted text lands in the archive’s content search as well as a .txt download. No upload, no server-side OCR.
Can I cut a .tiff's subject out of its background?
Yes. The viewer’s eraser button runs an in-browser salient-object model (u2netp on WebAssembly) on the page you are viewing and hands you a transparent PNG — the background never touches a server. A folder batch does the same for every TIFF’s first page; see remove background from image.
Do you upload my .tiff?
No. The TIFF engine is JavaScript running in your tab; the file never leaves your machine. Confirm it with DevTools (F12, Network tab — no request carries your image) or by going offline after the page loads: viewing keeps working.
