How to Make Large Files Easier to Email and Upload
Practical steps for reducing file size before sending documents and images through size-limited services.
Check the limit first
Different email, application, and upload services impose different file-size limits. Knowing the target limit helps you decide how aggressively to compress a file instead of reducing quality more than necessary.
Compress the right file
Use PDF compression for documents and reports. Use image compression for photos, website assets, and other raster images. Pick the file-specific tool so you can control the settings that matter for that format.
Keep the original
Save the original file separately and treat the compressed version as a distribution copy. This makes it easy to create another version later with different quality settings.
