FAQ for 45 KB JPEG Compression
Common questions about 45 KB JPEG sizing.
45 KB is ideal for community posts, forum previews, and announcement cards where you need clear thumbnails without heavy page weight. It keeps feeds fast and cards readable in busy discussion lists. It works well for mobile community apps.
45 KB gives a touch more clarity than 40 KB while staying lighter than 50 KB for faster feeds. Use 45 KB when you want readable preview cards without adding much extra payload. It is a safe middle target for community platforms.
Short labels can remain readable if the image is clean and uses strong contrast. Avoid tiny fonts and busy backgrounds. Preview at the final card size to confirm clarity before publishing. Check on mobile to verify small text.
Often yes. A small downscale is usually enough to reach 45 KB without visible artifacts. Keep the aspect ratio locked so cards remain aligned across the feed. Small reductions help keep file size consistent across a set.
No. 45 KB is designed for small preview cards, not for full width hero images. Use larger targets for hero sections and keep 45 KB for feeds and listings. Cover images need more detail. Event banners should use higher targets.
If the file is already under 45 KB, it exports unchanged to avoid recompression. That preserves current quality while keeping the file lightweight for community pages. This avoids recompressing assets that are already optimized.
Yes. Compression runs in your browser, so images are not uploaded or stored. This keeps community assets private and lets you iterate quickly on preview cards. Local processing also speeds moderation workflows.
Use simple backgrounds, clean crops, and avoid heavy noise. Clean scenes compress better and stay sharp at 45 KB. If the preview looks soft, reduce dimensions slightly and recheck at final size. If needed, simplify backgrounds before export.
