Why Compress to 15MB?
Raw photo competition entries from organizations like the International Photography Awards (IPA) and Prix Pictet allow submissions up to 15-20MB, and compressing to 15MB ensures your entry passes size validation while retaining maximum quality. Medical imaging workflows — radiology department image sharing, dermatology documentation, and dental X-ray archives — often require JPEG exports under 15MB for PACS (Picture Archiving and Communication System) compatibility. Large-format document scans of architectural blueprints, engineering drawings, and historical manuscripts at 300-600 DPI produce files that need precise compression to 15MB for digital archive systems. WeTransfer's free tier processes 15MB files instantly, making this a practical target for professional file exchange.
Tips for Compressing to 15MB
For competition entries, verify whether the portal measures file size in MB (1,000,000 bytes) or MiB (1,048,576 bytes) — SizeSnap uses standard MB.
Medical images should be compressed in consultation with your facility's IT department to ensure compliance with diagnostic image quality standards.
Large scans at 15MB retain enough resolution for zooming into fine text and line work in architectural drawings.
