Cómo optimizar imágenes de blog antes de subirlas
Checklist práctico para reducir peso sin perder claridad en tus artículos.
Subir imágenes sin ajustar suele ralentizar el blog. Un proceso corto antes de publicar mejora velocidad y experiencia.
Set a target width per content block
Define a default width for hero images and inline images.
This avoids random image sizes across posts and reduces file waste.
Pick format by content type
Use JPG/WebP for photos and PNG for diagrams needing crisp edges or transparency.
Avoid using one format for everything just out of habit.
Compress with readability in mind
Blog screenshots must keep text readable after compression.
Test a small quality range and keep the lightest acceptable version.
- Check text labels at normal zoom.
- Review mobile view once.
- Avoid aggressive compression on charts.
Rename and organize files before upload
Use clear file names so your media library stays maintainable.
Consistent naming also helps when replacing old files later.
Preview the post before publishing
Open the draft on desktop and mobile to confirm quality and loading.
If an image still looks heavy, optimize that file again before publishing.
Use this when
- Publishing tutorials with screenshots.
- Preparing long-form blog posts.
- Improving mobile readability.
- Updating older slow articles.
Optimize once, publish faster
A 2-minute image check before uploading prevents most blog image performance issues.
