Reduce Image Size for Email

Most email providers limit attachments. That limit covers all attachments combined, not each file individually.

Individual images from modern cameras can be 5–15 MB each, so a few photos can exceed the limit quickly.

• → Compress — Re-encode at lower quality. JPG at quality 75 is often 40–60% smaller with minimal visible difference. Use the JPG compressor or WebP compressor.
• → Convert format — Switch to a more efficient format. WebP or AVIF files are 30–50% smaller than JPG at similar quality. Use the WebP converter. Caveat: the recipient needs a browser or app that supports the format.
• → Both — Convert to WebP or AVIF and compress for maximum reduction. This gives the smallest possible files.

For maximum compatibility: compress your JPG files to quality 75 using the JPG compressor. Every email client and device can open JPG.

For tech-savvy recipients: convert to WebP at quality 70. The files will be noticeably smaller.

• → Don't compress multiple times — Each round of lossy compression degrades quality further. Compress once from the original file.
• → Send a link instead — For many large files, upload them to a cloud service and share the link rather than attaching each file.
• → Consider the use case — Does the recipient need full resolution? For viewing on screen, quality 75 is usually more than enough.
