# Why your Simplebooklet is Taking a Long Time to Load

# **Why your Simplebooklet **i**s Taking a Long Time to Load**

If your Simplebooklet feels slow to open or pages take time to display, the issue is usually related to file size, device performance, or optimization settings — not a platform error.

This guide walks through the most common causes and how to fix them.

|| Available on all plans.

## **Common Reasons a Simplebooklet Loads Slowly**

### 1. Your File Is Large

The most common cause of slow loading is a large uploaded PDF.

This typically happens when:

* The PDF contains high-resolution images

* The file includes many pages

* The file was exported in “Print Quality” settings

* The PDF includes embedded design layers

### How to Fix It

We strongly recommend compressing your PDF before uploading.

You can use a free tool like:

Steps:

1. Upload your PDF to ilovepdf.com

2. Choose compression

3. Download the new file

4. Re-upload it to Simplebooklet

In many cases, this instantly improves loading speed.


### 2. Large Images Inside the PDF

Even if the page count is low, extremely high-resolution images can cause slow performance.

If your PDF was designed for print at 300 DPI, it may be much heavier than necessary for web viewing.

Compressing usually resolves this.


### 3. GIFs Can Slow Things Down

Animated GIFs are surprisingly heavy files.

Multiple GIFs — or large ones — can significantly increase load times.

#### Recommended Alternative

Instead of uploading a GIF, upload it as a **video file** inside your Simplebooklet.

Video compression is much more efficient and performs significantly better than GIFs.


### 4. Device or Browser Limitations

Sometimes the issue isn’t the file — it’s the viewer’s device.

Loading may be slower if:

* The device has limited memory

* The browser has many tabs open

* The connection speed is low

* An older browser version is being used

#### What to Try

* Refresh the page

* Close unused tabs

* Try a different browser (Chrome works best)

* Clear browser cache

* Test on another device


## **Use Built-In Optimization Tools**

If your booklet has many pages or large visuals, you can enable performance optimization inside the Design tab.

### **Enable Optimize Page Load**

This setting loads only the pages currently being viewed instead of loading the entire booklet at once.

To enable:

1. Open your **Dashboard**

2. Select your Simplebooklet

3. Click the **Design** tab

4. Select **Advanced**

5. Toggle on **Optimize Page Load**

When enabled, only the three visible pages load at a time, improving performance significantly.


### **Enable Optimize Image Load**

This setting loads images only when they are needed instead of all at once.

To enable:

1. Open your **Dashboard**

2. Select your Simplebooklet

3. Click the **Design** tab

4. Select **Advanced**

5. Toggle on **Optimize Image Load**

This is especially helpful for image-heavy booklets.


## **When Is It Not a File Issue?**

If:

* Only one viewer reports slowness

* It works well for others

* The booklet loads normally after refresh

It is likely device or connection related.


## **Quick Performance Checklist**

Before contacting support, check:

* Compressed PDF?

* Reduced image size?

* Avoided large GIFs?

* Enabled Optimize Page Load?

* Enabled Optimize Image Load?

* Tested on another browser?

Most performance concerns are resolved with one of these steps.
