Heavy images and mismatched layouts hurt store presentation
Standard product photos are often too large, use legacy formats, and carry generic camera filenames that search engines ignore. Making different supplier images look uniform by hand takes hours of tedious manual work.
- Raw camera files are far larger than a product grid needs, consuming storage and bandwidth.
- Unoptimized filenames like IMG_4920.jpg miss out on valuable search-engine image traffic.
- Mismatched product crops and busy backgrounds make catalog grids look messy and unaligned.
Modern formats, uniform layouts, and built-in AI tools
Rotozoom Image Optimizer automates your media workflow. It converts images to modern AVIF and WebP formats, replaces generic camera filenames with descriptive search-readable names, and standardizes your layouts — all while keeping your original files completely safe.
Next-gen format conversion
Convert your JPEG and PNG uploads to AVIF and WebP. Conversion runs in the background as part of your media workflow.
SEO filename renaming
PROReplaces generic camera filenames with descriptive, search-readable ones.
Local & cloud AI background removal
Remove busy backgrounds from product photos. Use on-board, local browser-based AI to edit images one by one, or upgrade to Pro for cloud-based bulk background removal.
Uniform product imagery
Trim dead space, resize, and pad images to a square aspect ratio so every product card in your grid lines up, whatever the original photo dimensions.
Reversible original backups
Every optimized image keeps its high-resolution original safely stored. Because every original is preserved, nothing you convert is a one-way door.
Where it fits
A store uploads raw supplier photos with different background styles and mismatched dimensions.
→ They use the renamer for clean filenames, pad images to square so the grid aligns, and use AI background removal for a uniform look.
A long-running WooCommerce store has legacy JPEG uploads that were never converted to modern formats.
→ They run the bulk library optimizer to convert every historical image to AVIF and WebP in the background, keeping original backups safe.
How Rotozoom Image Optimizer compares
Many popular optimizers process your images on their own servers, priced by sites or metered by monthly usage. Rotozoom converts on your own hosting instead — here's the trade-off.
A mature optimizer with a built-in image CDN and a large install base, backed by WPMU DEV; priced by number of sites.
Rotozoom → Rotozoom runs unlimited bulk AVIF and WebP conversion on your own server and keeps every original safely backed up.
A simple SaaS optimizer from the WP Rocket team; plans allow unlimited sites but meter a monthly image-data allowance.
Rotozoom → Rotozoom processes locally at one flat yearly price, with no monthly data allowance to track.
Choose Smush or Imagify if you'd rather offload processing to an external service and your host CPU is limited. Choose Rotozoom to keep conversion on your own server, unlimited, at €49/yr.

Frequently asked
Does this plugin delete my original images?
No. It keeps a backup of every original image, so any conversion is reversible.
What is the difference between AVIF and WebP?
Both are modern formats. AVIF is the newer of the two; WebP has the longer track record. The plugin converts to both, so your library holds the modern versions alongside your originals.
How does the AI background removal work?
Free users remove backgrounds from individual images inside their browser using local machine learning. Pro adds cloud-based bulk background removal to process many images at once.
What do I get in Free vs Pro?
There is no daily limit. Free covers AVIF and WebP conversion, trimming, resizing, pad-to-square, bulk library processing and local in-browser AI background removal. Pro adds SEO filename renaming, image size limits, product-only scoping, and cloud AI bulk background removal.
Can it automatically resize large image uploads?
Yes. Trimming, padding to square and resizing are included in the free version; Pro adds an upload size limit that automatically caps the longest side of new images, so oversized uploads are scaled down as they come in.
Does it replace my images with WebP, or keep the originals?
It converts your JPEG and PNG images to AVIF and WebP and serves those modern formats, while keeping every original safely backed up — nothing is overwritten, so any conversion can be reversed.
