Puluno Images
A standalone WordPress plugin for safe JPEG/PNG compression and resize — original backups, rollback, a queue for heavy files, and optional WebP / AVIF sidecars next to the original.
In WP admin: Puluno Images → Guide and Setup guide — this site react to your scan and installed plugins. This page is the general reference on puluno.io.
Quick start
- Install Puluno Images (download ZIP) and activate.
- Open Puluno Images in the menu — let the library scan finish.
- Run the queue for heavy photos (originals stay in backup).
- In Settings, enable WebP sidecar; after saving, backfill older files with Backfill WebP.
- Use the plugin Guide tab for step order and cache notes.
Recommended order (efficient)
| Step | What | Why |
|---|---|---|
| 1 | Fix conflicts (red banner) | Two JPEG optimizers can corrupt originals |
| 2 | Shrink heavy JPG/PNG in the queue | Biggest LCP and disk win |
| 3 | Soft photos — replace in Media | Compression cannot fix blur |
| 4 | WebP sidecar + backfill | Smaller download for browsers |
| 5 | AVIF (Pro, optional) | Even smaller files; more disk use |
WebP/AVIF counts: Center → Modern formats.
WebP and AVIF — on disk vs. what visitors download
- WordPress still exposes URLs like
photo.jpg. - Puluno creates
photo.webp(and optionallyphoto.avif) beside the file — not a new Media Library item. - Visitors download one format: best supported (AVIF → WebP → JPG) via
.htaccesscontent negotiation. - Extra files on the server are normal — you trade disk for speed.
LiteSpeed Image Optimization already delivers WebP/AVIF? Puluno skips sidecars — turn off image optimization in LiteSpeed, keep page cache.
Cache and hosting (when you are not sure)
| Situation | Action |
|---|---|
| Puluno shows a conflict | Follow the banner — disable compression in the other plugin |
| LiteSpeed Cache | Page cache OK; disable its image optimization if you use Puluno |
| WP Rocket / SG Optimizer / Smush… | Same rule: one JPEG pipeline; keep HTML cache |
| Cloudflare Polish / CDN image opt | Either CDN or Puluno on origin — not both on the same photos |
| After first WebP or bulk optimize | Purge page cache once on host/CDN |
Puluno cannot see your host type, but it detects plugins — use Setup guide — this site in admin.
Free vs Pro
| Free | Pro | |
|---|---|---|
| Optimizations / month | limited | unlimited |
| Original resize | typically up to 1920 px | up to 2560 px |
| On upload | limited | yes |
| AVIF sidecar | — | yes |
| VPS worker (mozjpeg) | optional | optional |
Images Pro / Shop / Complete license: Settings → License.
When to use (or skip) Images
- Yes — camera JPG/PNG, shops, heavy media libraries.
- Skip / careful — you already upload WebP only; photos are soft (replace original); disk is full (queue first, AVIF later); another plugin already rewrites JPEG.
Family integration
- Pulse — prioritizes heavy images affecting LCP.
- SEO Media — alt text; Images handles bytes and formats.
