A TIFF file is almost always too large to send by email. Gmail has a 25MB attachment limit, Outlook has a 20MB limit, and most TIFF files from cameras or scanners are 20-100MB. The solution: convert to WebP before attaching. A 50MB TIFF becomes under 1MB at quality 85 — well within any email provider's limits. The conversion takes under 30 seconds in your browser.
Why TIFF Files Exceed Email Limits
TIFF files are large by design. A 24-megapixel camera photo saved as uncompressed TIFF is around 70MB. A full-page scan at 300 DPI is 20-40MB. Multi-page document scans can be hundreds of megabytes.
Email providers impose attachment limits to prevent server overload:
- Gmail: 25MB per email
- Outlook / Exchange: 20MB (often reduced to 10MB by IT policy)
- Yahoo Mail: 25MB
- Apple Mail: 20MB (larger files go via iCloud Mail Drop)
Even the most generous limit (25MB) is smaller than most TIFF files from modern cameras. You need to compress before sending.
Fastest Method: Convert TIFF to WebP in Your Browser
- Open the TIFF to WebP converter in your browser — Chrome, Edge, Safari, Firefox all work.
- Drop your TIFF file into the converter.
- Set quality to 85 — the default. This reduces a 50MB TIFF to under 1MB in most cases.
- Click Convert and download the result.
- Attach the WebP file to your email instead of the original TIFF.
The recipient gets a file that looks identical to the TIFF on any screen but is 50-100x smaller. If they need the original TIFF for print or editing, send it via a file sharing service (Google Drive, Dropbox, WeTransfer) with a link in the email body instead.

Three good options, in order of recommendation:
- WebP (recommended): Smallest files, excellent quality, supported by all modern email clients and browsers. Outlook on older Windows may not preview WebP inline, but recipients can still open and view the file.
- JPG: Universal compatibility — works in every email client including old versions of Outlook. About 2-4x larger than WebP at equivalent quality, but still 85-95% smaller than TIFF. Use JPG if your recipient uses old email software.
- PNG: Lossless but usually larger than JPG or WebP for photographs. Use PNG only when you need transparency or the image has sharp-edged graphics.
For most professional email scenarios, WebP is the right choice. For maximum compatibility across all recipients, JPG is the safe default. Use the TIFF to JPG converter if JPG is needed.
Alternatives: Sharing Large TIFF Files Without Compressing
If the recipient specifically needs the original full-quality TIFF (for print production or professional editing), do not compress it — use a file sharing service instead:
- Google Drive: Upload the TIFF and share a link. Free up to 15GB.
- Dropbox: Similar to Drive, good for large files up to 2GB on the free plan.
- WeTransfer: No account required, transfers up to 2GB free. The link expires after 7 days.
Send the sharing link in the email body rather than attaching the TIFF directly. This is the standard workflow when a designer, photographer, or printer needs original files.
For email delivery where the recipient just needs to view the image (not edit or print it), converting to WebP is always the right choice.

What is the fastest way to compress a TIFF file for Gmail?
Convert it to WebP in your browser. A 50MB TIFF becomes under 1MB in under 30 seconds — well within Gmail's 25MB limit. No software install needed.
Will the image look different if I send WebP instead of TIFF?
On screen, no — quality 85 WebP looks identical to the original TIFF. If the recipient needs the TIFF for print production or professional editing, share the original via Google Drive or WeTransfer instead.
Can Outlook open a WebP file attachment?
Modern Outlook (Microsoft 365) supports WebP. Older versions of Outlook on Windows may not preview WebP inline, but recipients can still download and open the file in any modern browser or image viewer.
Should I send TIFF or WebP to a graphic designer?
Send the original TIFF via a file sharing link if they need to edit or print it. Send WebP if they just need to review or approve the image visually.
