Frequently asked questions.
Practical answers for site owners, developers and agencies.
Does the free version have unlimited WebP conversion?
Yes. The free plugin is intended to convert Media Library images to WebP without artificial file limits.
Does it delete my original JPG or PNG files?
No. The plugin generates sidecar files such as image.jpg.webp and keeps the original files as fallback.
Is AVIF included in Free?
No. AVIF is a Pro feature because it needs additional server checks, fallback logic, native WebP/AVIF handling and format selection.
Will this work with custom image sizes?
Yes. The plugin is designed to track original Media Library images and generated WordPress sizes separately.
What happens if WebP is missing?
The original image remains available. The plugin only serves a generated file when it exists and is safe to serve.
Why would I need Pro?
Pro is for AVIF, Website Optimization reports, layout and delivery fixes, LCP warnings, folder scans, exclusions, scheduled maintenance, WP-CLI and restore-safe cleanup.

How to convert new WordPress uploads to WebP automatically
New image uploads are one of the easiest places to start. Titanium WebP Optimizer can convert new JPG and PNG Media Library uploads to WebP locally, including registered WordPress image sizes, while keeping the original source images untouched.
How to set it up
- Install and activate Titanium WebP Optimizer on the WordPress site.
- Open the plugin settings and check the server capability status for WebP support.
- Enable automatic WebP conversion for new JPG and PNG uploads.
- Upload a test JPG or PNG image through the Media Library.
- Open the image status or Media Library column to confirm that the WebP sidecar was generated.
- Clear page/cache plugin caches if the frontend still shows an older cached image response.
How to run 1 Click Full Optimization for a WordPress Media Library
Not every site owner wants to choose between scan, rebuild, missing-only, retry and repair tasks. The 1 Click workflow is designed to run the safe optimization path in a clear order, so beginners can optimize a Media Library without understanding every advanced queue option first.
How to use it
- Open the Convert or Optimization page in Titanium WebP Optimizer.
- Review the starting dashboard totals and any visible server warnings.
- Start the 1 Click Full Optimization workflow.
- Let the background queue process images in controlled batches.
- Watch progress, elapsed time and result tiles until the workflow is finished.
- Review missing formats, saved failures and saved space after completion.
How to build the image status database and understand the results
The status database gives you a clearer picture of what actually exists on disk. It can show source images scanned, existing generated files, missing formats, missing WordPress sizes, saved failures and estimated saved space instead of guessing from random folder checks.
How to use the status database
- Open the plugin dashboard or Convert page.
- Run the database build or full scan task.
- Wait for the scan to inspect Media Library images and generated sidecar files.
- Check the totals for existing WebP or AVIF files, missing formats and missing WordPress sizes.
- Use the result tiles to decide whether to run missing-only conversion, retry failures or rebuild tasks.
How to convert only missing WebP or AVIF files
After a full library has already been optimized, you usually do not want to regenerate every file again. Missing-only conversion focuses on the gaps found by the status database, which is useful after theme changes, custom size changes, interrupted queues or imported media.
How to run a missing-only workflow
- Build or refresh the image status database first.
- Review the missing formats and missing WordPress size totals.
- Choose the missing-only conversion task instead of a full rebuild.
- Let the background queue process the missing items.
- Refresh the dashboard totals after the queue finishes.
- Retry saved failures separately if any files still could not be generated.
How Titanium keeps original images safe with sidecar files
Titanium does not need to overwrite original JPG or PNG source files. It can generate sidecar files such as image.jpg.webp or image.png.webp while keeping the original file available for fallback, compatibility and rollback safety.
How to explain the workflow
- The original Media Library file remains in place.
- The plugin generates an optimized sidecar file beside the source file.
- Delivery rules or safe HTML replacement can serve the optimized format when available.
- If the optimized file is missing or unsupported, the original image remains available.
- Native WebP files are handled without creating unnecessary .webp.webp duplicates.
How to add AVIF conversion and fallback delivery in Pro
WebP is a strong default format, but AVIF can reduce image weight further on browsers and servers that support it. Titanium Pro adds AVIF conversion and delivery with fallback logic, so the site can use AVIF where appropriate and still fall back to WebP or the original file when needed.
How to approach AVIF safely
- Check server capability support before enabling AVIF conversion.
- Start with a small test batch or staging site if the library is large.
- Generate AVIF sidecars for existing source images.
- Confirm that AVIF, WebP and original fallback behavior works on the frontend.
- Use status totals to track existing AVIF files and missing AVIF files separately from WebP.
- Clear caches after changing delivery behavior.
How to use Website Optimization reports after conversion
Image format conversion is only one part of image performance. Pro Website Optimization reports help find issues such as layout shift risks, oversized image delivery, LCP/hero image warnings, broken images, image SEO gaps, WooCommerce image problems and social preview image issues.
How to use the reports
- Run normal WebP or AVIF conversion first so optimized formats exist.
- Open the Website Optimization area in Pro.
- Run the relevant scan, such as oversized delivery, LCP warnings or layout shift.
- Review the report before using any fix button.
- Apply safe fixes in smaller groups on important pages first.
- Clear caches and re-check the affected pages after changes.
How to find unregistered uploads and folder images
Some WordPress sites have images inside uploads folders that are not registered in the Media Library. This can happen after manual FTP uploads, migrations, page builder exports or old site moves. Titanium can help detect these files so they are not invisible during normal Media Library optimization.
How to review unregistered files
- Run the unregistered uploads scan or manager.
- Review the dated uploads folders and detected image files.
- Ignore files that should not be managed by the plugin.
- Restore ignored files if you later decide they should be reviewed again.
- Use Pro when you need imports to Media Library or optimization without Media Library import.
How to optimize large WordPress image libraries safely
Large Media Libraries need controlled processing. Instead of trying to convert thousands of images in one request, Titanium uses background queues with pause, resume, stop and live progress. Pro adds scheduling, advanced exclusions and WP-CLI workflows for larger sites and agencies.
Large-site workflow
- Run server capability checks before starting heavy conversion jobs.
- Build the status database so you know the real starting point.
- Use background queues instead of repeated manual page refreshes.
- Pause or stop the queue if the host is under heavy load.
- Run missing-only or retry tasks after the first pass instead of rebuilding everything.
- Use Pro scheduling or WP-CLI for controlled maintenance on bigger sites.
How to use cleanup and restore-safe workflows without breaking images
Image cleanup should be careful. Pro restore-safe tools are designed to review old resized sidecars, duplicate source candidates and cleanup targets before permanent deletion. The goal is to reduce clutter without removing files that the site still needs.
Safer cleanup workflow
- Run a report before deleting any generated files.
- Review the file list, paths and reason each item was detected.
- Use quarantine or restore-safe options where available.
- Delete in smaller batches instead of clearing everything at once.
- Check key pages, product pages, landing pages and mobile views after cleanup.
- Use the restore list when a cleaned file needs to be recovered.
Start with local WebP, upgrade when the site needs AVIF and deeper reports.
