# ๐๏ธ Image compression
{% hint style="info" %}
**Who can use this feature?**
* Image compression is available on **all plans**.
* Monthly limits depend on your plan:
* **Free** (100)
* **Basic** (10,000)
* **Pro** (50,000)
* **Expert** (unlimited).
{% endhint %}
### What is Image compression?
Big image files are usually the biggest reason a store loads slowly. A single uncompressed product photo can be several megabytes.
Image compression squeezes those files down to a fraction of their size while keeping them looking sharp. Customers see the same photos โ they just arrive much faster.
If you don't like how an optimized image turned out, you can roll back to a previous version in seconds.
### Why use Image compression?
* **Faster page loads** โ smaller image files are the single biggest speed win for most stores.
* **No visible quality loss** โ Automatic mode keeps photos sharp while cutting file size.
* **Full control when you want it** โ choose fixed quality levels or compress specific images by hand.
* **Saves your quota** โ "Optimize unoptimized" skips already-processed images.
* **Risk-free** โ revert to any earlier version in seconds.
### โ๏ธ How to use Image compression
#### Step 1: Open the Compression tab
Go to **Image optimizer โ Compression**.
#### Step 2: Check your image quota
Check the **Image quota** bar near the top to see how many images you have left this month and when your quota resets.
#### Step 3: Review your Report
Look at the **Report** card to see your current savings โ **Total compression** % (with a status badge like "Good") and **Saving** in MB.
#### Step 4: Choose your image quality
In the **Image compression** card, choose your **Image quality**:
* **Automatic โ 92%** *(default)* โ keeps your photos looking sharp while still cutting the file size. Best for most stores.
* **92%**, **80%**, and other fixed levels โ pick a specific quality if you want full control. Lower numbers mean smaller files but more visible quality loss.
#### Step 5: Run the optimization
Click **Optimize now** and pick one of two options:
* **Optimize all** โ recompresses every image in your store. Use this when you've changed the **Image quality** setting and want to re-run on everything.
* **Optimize unoptimized** โ only compresses images that haven't been processed yet. Faster, and saves quota.
Want to compress specific images only instead? Click **Optimize manually** to pick them by hand.
#### Step 6: Let it run in the background
While the job runs, you can keep using the app โ it works in the background. Click **Notify me** to get a notification when the optimization is done.
#### Revert to a previous version
Didn't like how the compression turned out? You can go back to any earlier version.
1. Click the **revert icon** (the circular arrow) next to **Optimize manually**.
2. Pick which version to go back to:
* **Revert to original version** โ restores your images before any compression.
* A recent version from the list โ restores from a specific date.
* **View more versions** โ opens the full History page.
3. Confirm the revert. The card switches to a progress view while your images are restored. You can keep browsing โ the job continues in the background.
4. When it's done, your store's images are back to the chosen version automatically. A success toast confirms the revert.

### ๐ Merchant Notes
* Click **History** at the top right of the page to see a full log of every optimization and revert.
* **Automatic โ 92%** is the best choice for most stores; only drop to lower fixed levels if you specifically want smaller files and accept some visible quality loss.
* Use **Optimize unoptimized** to save quota โ it skips images that have already been processed.
* Compression counts against your **monthly quota** (Free: 100 ยท Basic: 10,000 ยท Pro: 50,000 ยท Expert: unlimited); the quota bar shows when it resets.
* You can **revert any time** to your original images or an earlier version โ reverts run in the background.
* To improve your image alt text for SEO and accessibility, see [**Alt text optimizer**](https://app.gitbook.com/o/J4yqZKSNdRshQVCe8UnM/s/e2UyZIDUxUYqjZFfFANX/~/edit/~/changes/20/speed-optimizer/image-compression/alt-text-optimizer).
