Why Compress to 3MB?
Standard DSLR web exports from Lightroom Classic and Capture One typically land between 2MB and 5MB at quality 80-90. Targeting 3MB gives photographers a consistent, bandwidth-friendly file weight for delivering client proofs via galleries on Pixieset, ShootProof, and Pic-Time. Professional portfolio platforms like Format and Cargo recommend images in the 2-4MB range for optimal page-load speed without sacrificing the sharpness that art directors expect. Slack and Microsoft Teams handle 3MB image uploads smoothly in channels, making it a practical cap for sharing project visuals with remote teams.
Tips for Compressing to 3MB
For client proofs, 3MB preserves enough detail for on-screen review at 100% zoom while keeping gallery pages responsive.
If exporting from Lightroom, skip the export quality slider entirely and let SizeSnap handle the targeting — it will find the optimal quality more precisely.
