Supports: DOC
A .doc file is a Word document: reflowable text, styles, and layout instructions stored in a binary container. A .tiff file is the opposite — a fixed grid of pixels with a rich tag-based header, the format document-imaging and preservation systems have standardised on since the early 1990s. Converting between them means rendering the document's pages and freezing them as images, which is exactly what archives, records-management systems, and print bureaus ask for when they say "send it as TIFF". This page explains what both formats actually are, then how the conversion runs.
| Property | Value |
|---|---|
| Full name | Microsoft Word Binary File Format |
| Specification | Published by Microsoft as the [MS-DOC] Open Specification |
| Container | OLE Compound File binary storage — multiple internal streams in one file |
| Era | Word's default save format through Word 2003; still readable by current Word |
| Stores | Text, styles, tables, headers and footers, embedded objects, revision marks, macros |
| Text model | Real characters — reflowable, searchable, editable |
| Superseded by | .docx (Office Open XML, ECMA-376 / ISO/IEC 29500), Word's default since 2007 |
| Property | Value |
|---|---|
| Full name | Tagged Image File Format |
| Specification | TIFF Revision 6.0 (1992), originally from Aldus, now maintained by Adobe |
| Structure | Header plus Image File Directories (IFDs) of tagged fields; one file can hold multiple images |
| Colour models | Bilevel, greyscale, palette, RGB and CMYK, at a range of bit depths |
| Compression | LZW, Deflate, PackBits, CCITT Group 3/4, lossy JPEG, and newer WebP/ZSTD/JP2K options |
| Maximum file size | 4 GB in classic TIFF (32-bit offsets); BigTIFF lifts this with 64-bit offsets |
| Browser support | Not a web format — of the major browsers, only Safari displays image/tiff |
| Extensions | .tiff and .tif — identical data, two spellings |
| Best for | Archival masters, document imaging, prepress and print workflows, OCR input |
.doc onto the drop zone or click "Add Files". Every page of the document is rendered separately, so a 20-page file returns 20 numbered images.Our pipeline lays the document out with LibreOffice on the server, prints it to an internal PDF so pagination is fixed exactly as Word would print it, renders each page at your chosen DPI, and encodes each of those page images as a separate TIFF. Two consequences are worth stating plainly. First, the output is one TIFF per page — TIFF can hold many images in a single file, but this conversion does not build a multi-page container, so a 20-page document gives you 20 files plus a zip option. Second, the "Image Transparency" colour applies before encoding: pages are composited onto White by default, which is what you want for documents that will be printed or archived.
The Quality Preset only bites when the chosen compression is lossy. On JPEG, WebP, or JP2K it sets the encoder quality — Very High (Recommended), the default, drives it at 95. With LZW, Deflate, PackBits, or None there is nothing to discard, so the preset makes no difference to the output.
Because a lot of institutional systems only accept images. Records-management and document-imaging platforms, court and government e-filing systems, prepress workflows, and long-term preservation repositories all standardised on TIFF, and they want a page image with a known resolution rather than a file whose appearance depends on which fonts the reader has installed. Rasterising also freezes the layout: nobody downstream can accidentally reflow or edit it.
One file per page. The format itself supports multi-image files — that is what the IFD chain is for — but this converter writes each rendered page as its own TIFF. Use "Download All (Zip)" to keep the set together, or convert to PDF if a single paginated file is what the recipient actually needs.
.tiff the same as .tif?Yes. The two extensions describe the same format; .tif exists because MS-DOS filenames allowed only three characters. The page's "File extension" control lets you choose which spelling the output files use, and readers accept both regardless.
LZW unless you have a specific reason not to — it is lossless, well compressed on text pages, and the codec every TIFF reader implements. Deflate is also lossless and can be slightly smaller. JPEG makes the smallest files but is lossy and is rejected by some viewers and print workflows, which is why the interface warns about it. None writes raw uncompressed pixels: universally readable, very large.
Generally not. TIFF was never adopted as a web image format; among the major browsers only Safari renders image/tiff, so a TIFF linked from a web page will usually download instead of displaying. If the images are destined for a website, chat, or email body, convert to PNG or JPG instead.
No. The pages become pixel grids, so the characters are gone as characters — no selecting, no searching, no screen-reader access. Getting text back out of a page image requires OCR, which is why archival scanning guidance leans on 300 DPI or better: OCR engines need enough pixels per glyph to recognise them reliably.
Most document-imaging programmes work at 200 to 300 DPI for everyday records and 400 to 600 DPI for preservation masters or pages with very small type. Our presets are labelled to match that thinking — 200 DPI (Office Standard), 300 DPI (High Quality / Print Recommended), 400 DPI (Small Text / OCR), 600 DPI (Ultra High / Archival). Since pixel count rises with the square of the DPI, jumping from 300 to 600 roughly quadruples the raw image data.
Rendering is done by LibreOffice on our servers. When a document references a font that is not installed there, a metrically similar face is substituted: pagination and line breaks normally hold, but glyph shapes can differ. Embedding fonts in the document, or using widely available families, produces the closest match. Password-protected .doc files cannot be opened for rendering at all — remove the protection in Word first.
It is uploaded over an encrypted connection, converted on our servers, and deleted automatically after a few hours. No sign-up, no watermark, and files are never shared or made public.
