Free online EML to TIFF converter

Document-management, court-filing, and imaging systems may accept TIFF files but not email files. Rendering an EML message as TIFF creates a page image for archiving, printing, or submission, while attachments usually require separate handling.

What the EML format is

EML is a plain-text email file based on RFC 5322 and MIME. It stores message headers such as sender, recipients, date, and subject, plus the body, inline images, and attachments encoded within the file.

Mozilla Thunderbird, Windows Mail, Apple Mail, and other MIME-aware mail clients can create or open EML files. EML files commonly come from exported messages, saved email, and systems that preserve individual messages in a portable format.

What the TIFF format is

TIFF (Tagged Image File Format) is a raster-image format used for scanned records, document-management systems, publishing, and print workflows. It supports monochrome, grayscale, and color images and can store multiple pages in one file.

TIFF can use lossless LZW or ZIP compression, preserving rendered text and line detail. For black-and-white pages, CCITT Group 4 compression can produce smaller files. TIFF normally does not preserve an email's searchable headers, links, message structure, or editable text; OCR is required to add searchable text to the rendered image.

Convert an EML file with 101convert

1. Open the EML-to-TIFF converter on 101convert.com. It can be used free without installing software.
2. Select or drag a .eml file into the upload area.
3. Start the conversion and wait for the message to be rendered.
4. Download the resulting .tif or .tiff file.

The TIFF normally contains the visible message body and rendered inline content. An attached PDF, image, spreadsheet, or other file may not be included as TIFF pages; save and convert attachments separately when the receiving system requires them. Do not upload confidential or regulated email unless the service's handling policy meets your requirements.

Convert locally through PDF

For confidential messages, open the EML in Thunderbird or another MIME-aware mail client, then choose File → Print and select a PDF printer. Convert the resulting PDF locally with ImageMagick:

magick -density 300 email.pdf -compress LZW email.tiff

For black-and-white documents, this command creates a bilevel TIFF using Group 4 compression:

magick -density 300 email.pdf -colorspace Gray -threshold 50% -compress Group4 email.tiff

The PDF delegate must be installed for ImageMagick to read PDF files. Use a separate output filename for each message. A multi-page TIFF can hold all pages of one rendered email, but attachments generally need separate output files.

Quality and compatibility limits

• Use 300 DPI for ordinary archival and printing. Around 200 DPI may be sufficient for screen-only records; 400–600 DPI usually increases file size without improving normal email text.
• Rendering captures appearance rather than email semantics. Headers, selectable text, hyperlinks, signatures, and conversation relationships may not remain machine-readable.
• Use one multi-page TIFF when the destination system expects one document. Use separate files when it indexes pages or attachments independently.
• TIFF applications differ in their support for compression, color models, multi-page files, and BigTIFF. For broad compatibility, use standard TIFF with 8-bit grayscale or RGB and LZW compression.
• HTML layout, fonts, remote images, embedded images, and signatures can render differently between mail clients and conversion engines. Review every page after conversion.
• Keep the original EML and all attachments alongside the TIFF when legal, evidentiary, or complete archival preservation matters; TIFF is a visual derivative, not a replacement for the source message.
