How to Send Large Files by Email — Free Solutions (2026)

Most email services in 2026 have a maximum attachment size of 25MB. If your files are too large, you need to either reduce the file size or find an alternative. Here are the best free solutions.

Method 1: Convert Images to WebP Before Attaching

If you are attaching images to your email, convert them to WebP format first. WebP images are up to 35% smaller than JPG, which means you can attach more images without exceeding the limit.

Method 2: Convert PDF Pages to WebP

If you are sending a PDF that contains mostly images, convert the PDF pages to WebP and share the images instead of the heavy PDF file.

Method 3: Merge and Compress

Instead of sending multiple loose files, merge them into one compressed PDF. A single well-organized PDF is easier to send and often smaller than many separate image files.
