Email Compression Tips
Know Your Limits
Gmail: 25 MB total attachments. Outlook: 20 MB. Yahoo: 25 MB. Compress images to 200-500 KB each so you can attach multiple photos without hitting limits.
Quality: 70-80%
For email, 70-80% JPEG quality is ideal. Recipients viewing images on screens won't notice the difference, but file sizes will be dramatically smaller.
Batch for Efficiency
Select all photos for an email at once, compress them together, and download as a ZIP. Then attach the individual compressed files to your email.
100% Private Compression
Unlike online compressors that upload your images to their servers, PhotoFormatLab processes everything locally in your browser. Your files are never transmitted anywhere — they stay on your device.
Safe for personal photos, business documents, and confidential images.
