Lighter WordPress media. Every original kept.
Downsize finds the heavy images on your site, shrinks them, and keeps every original safe to restore in one click.
Built on infrastructure you already trust
Connect once. See everything. Shrink it safely.
Downsize runs from a dashboard and a lightweight connector plugin on your site. Here is exactly what happens, start to finish.
Connect
Install the connector plugin and pair it with a one-time code. No WordPress password ever leaves your site.
Scan
Every file in your media library, listed by real size on disk, heaviest first. It flags what to leave alone.
Optimize, protected
Each file is backed up, shrunk, verified on disk, and swapped in atomically. Same URL, same dimensions.
See every file at its real size.
Most WordPress libraries are full of images nobody ever optimized. One upload can be 40 MB. Downsize reads the actual bytes on disk and sorts the heavy ones to the top.
- ✓Heaviest first. The 71 MB monster hiding in 2019's uploads surfaces in seconds.
- ✓Knows what to skip. Animated GIFs, files other plugins own, anything offloaded.
- ✓Savings before you commit. See what each file will roughly save before optimizing.

Nothing is ever lost. Nothing is ever broken.
Optimizing means overwriting files on a live site. That is only safe if the original is always recoverable. So every job follows the same order, and it never skips a step.
1 · Back up first
The original is copied to a protected folder and checksum-verified before anything else runs.
2 · Replace atomically
The smaller file is written to a temp file, verified, then swapped in with a single atomic rename.
3 · Verify on disk
Downsize re-reads the live file and confirms the bytes and dimensions are exactly what it expected.
Always · Restore
The exact original comes back byte for byte, on-site or from off-site copies, whenever you want it.
A real photo on a live WordPress site. 79% lighter, and the original came back byte for byte when we restored it.
- ✓Dimensions unchanged. 6200 x 4200 before and after. No layout shift.
- ✓Original preserved on the server, verified by checksum.
- ✓Restored perfectly. The recovered file matched the original hash exactly.
- ✓Works without us. Restore from your own wp-admin, even offline.
Every original, one click away.
Browse every backup Downsize has taken, restore a single file or a whole batch, and keep optional off-site copies. The backup manifest lives on your server, so restore works even if Downsize is unreachable.
- ✓On-site always. Originals stay on your server in a protected folder.
- ✓Off-site optional. Add encrypted cloud copies for belt and suspenders.
- ✓Kept as long as you choose. Retention is your call, forever by default.
