How to Reduce Attachment Size
Most email systems reject oversized attachments. Reduce size with format-aware tools — image/PDF/video compressors — instead of hoping a ZIP alone will magically shrink already-compressed media.
Quick take: Resize/compress media → compress PDFs → convert video → ZIP last if bundling.
Images
Resize huge camera photos, then use the Image Compressor or JPG/WebP tools. Convert HEIC → JPG for compatibility and smaller shares.
PDFs
Image-heavy scans shrink with the PDF Compressor. Split or extract pages if the recipient only needs part of the file.
Video
Convert MOV → MP4 and run the Video Compressor. Shorten clips when possible — duration drives size.
Key points
- ZIP doesn’t shrink JPEGs/MP4s much.
- Attack the biggest media first.
- Keep originals; attach delivery copies.

FAQ
Why didn’t zipping help?
ZIP shines on uncompressed folders of documents. Already-compressed JPG/MP4/PDF streams barely shrink further.
