DescriptionThe TIFF (Tagged Image File Format) is a widely-used file format for storing digital images, developed by Aldus Corporation (now owned by Adobe Systems). It is a versatile format that supports a wide range of color depths, resolutions, and image types, making it suitable for use in a variety of applications.

TIFF files can contain multiple images, each with their own characteristics such as resolution, compression, and color depth. They can also be uncompressed or compressed using a variety of methods, such as LZW, ZIP, and JPEG compression. Additionally, TIFF files can store metadata such as keywords, descriptions, and copyright information.

One of the key benefits of the TIFF format is its support for high-quality, lossless image compression. This makes it a popular choice for archiving and sharing images, especially in fields such as graphic design, printing, and photography. TIFF files can also support transparent backgrounds, making them ideal for use in web graphics and other applications where transparency is important.

TIFF files can be opened and edited using a wide variety of software programs, including Adobe Photoshop, GIMP, and Microsoft Paint. They are also supported by many operating systems and web browsers.

Overall, the TIFF format is a robust and versatile format for storing digital images. Its ability to support multiple images, high-quality compression, and metadata make it a popular choice for a variety of applications, especially those requiring high-quality images.

OST to TIFF Converter — Frequently Asked Questions ▼

OST (Offline Storage Table) is Microsoft Outlook's proprietary local cache format, storing emails, calendar events, contacts, and tasks for offline use. TIFF conversion is chosen specifically when you need a non-editable, fixed visual record of an email — for legal holds, e-discovery, compliance archiving, or feeding documents into an imaging workflow or DMS that accepts TIFF but not raw email formats.
Each TIFF page renders one email as it would appear printed: the message headers (From, To, Date, Subject) at the top, followed by the body. Long messages flow across multiple pages. Inline images embedded in the HTML body are rendered in position. File attachments that are common document types (PDF, DOCX, PNG, JPG) can be rendered as additional pages; other attachment types are noted on a cover sheet.
300 dpi is the standard for text-heavy business email destined for document management systems or legal review. It balances legibility and file size. Use 200 dpi for quick reference copies where storage is limited. For fine-print disclaimers, small fonts, or documents that will be subjected to OCR, use 400 dpi to ensure characters are distinguishable at the pixel level.
The converter produces an accurate visual rendering of the email content, suitable for record-keeping and review workflows. However, TIFF images created this way are visual snapshots — they do not carry cryptographic metadata or digital signature validation. For legally admissible evidence or chain-of-custody requirements, consult your legal team about the applicable standards in your jurisdiction before relying solely on TIFF images.
The online converter accepts files up to 50 MB. Most OST files used in business accumulate gigabytes of email over months or years, far exceeding this limit. For full mailbox archiving, use the CoolUtils desktop mail converter, which processes arbitrarily large OST files, supports folder and date filtering, and integrates into automated archiving pipelines.
The online converter handles one file at a time. For high-volume or recurring archiving — compliance exports, legal hold preservation, IT decommissioning workflows — use the CoolUtils desktop mail converter on Windows 7–11. It processes OST files from the command line, applies consistent DPI and compression settings across all messages, and runs silently without user interaction.
