Big pixels cost real seconds

Visitors bounce when hero images weigh 3–8 MB. Email clients choke on huge attachments. Social platforms re-compress anyway—so feeding them the right dimensions up front keeps your work looking sharp.

Quick dimension cheat sheet

Open Graph / link previews: ~1200×630—great for share cards.
Instagram square: 1080×1080; portrait 1080×1350.
Website hero: often 1600–1920px wide; always compress after resize.
Email graphics: keep width 600–800px and aim small file sizes.

Workflow that works: resize → compress

Resize to the largest size you will ever display. Use Image Resizer, lock aspect ratio, and avoid upscaling tiny sources.
Compress with Image Compressor. Start around 80–85% quality for photos; go lower only if you need a hard cap.
Spot-check at 100% zoom on faces, text in photos, and logos.

Lossy vs lossless (plain English)

Lossy (JPEG, WebP lossy) throws away invisible detail—great for photos. Lossless (PNG) preserves edges—better for UI shots with text. Pick the format that matches the subject, then compress.
