How do I keep my page loading fast?
A page in a Maglr publication loads faster when it holds fewer elements and smaller files. The more content you put on a page, the longer that page takes to load.
What affects how fast a page loads
When a visitor opens a Maglr publication, the page they open first is sent ready to display. The viewer then loads only the pages directly before and after the page being viewed, in the background, so the next or previous page is usually ready by the time the visitor moves to it. A page further away, for example one reached through the menu or a link, is loaded when the visitor opens it.
Because only a few pages are loaded at a time, how fast a page opens depends mostly on:
- Elements and effects: how many elements the page holds, and the effects and animations on them.
- File sizes: how large the images, GIFs and videos on the page are.
- The visitor's connection: how fast the visitor's internet connection is.
Keeping the number of elements and effects down
Every element on a page in a Maglr publication has to be loaded along with its settings. This is usually fast, but a page with many elements, each with its own effects and animations, can take longer than usual to load. If a page loads slowly, check whether some elements, effects or animations can be removed or combined.
Using images at the right size
An image in a Maglr publication only needs to be twice the size, in pixels, of the box it's shown in. For example, an image shown in a box of 100 × 100 pixels never needs to be larger than 200 × 200 pixels. A larger file looks no sharper on screen, but every visitor still has to download it, so the page takes longer to load.
Maglr compresses JPEG, PNG and WebP images automatically when you upload them, but it doesn't shrink them to the size they're shown at. Resize large images yourself before you upload them.
Keeping GIFs and videos light
GIFs and videos in a Maglr publication are stored as you upload them: Maglr doesn't compress them. They are often the heaviest files on a page, so keep them short and compress them before you upload them. A GIF can be at most 10 MB, and a video at most 100 MB.
Visitors with a slow connection
Not every visitor to a Maglr publication has a fast internet connection, and that is outside your control. Maglr serves publications through a content delivery network (CDN), which stores copies closer to your visitors. The best way to help visitors on a slow connection is to keep each page light: fewer elements and effects, and smaller images, GIFs and videos.
Frequently asked questions
Does the number of pages slow down my publication?
Not much. A Maglr publication loads the page the visitor is viewing plus the pages directly before and after it, not all pages at once. Pages further away are loaded when the visitor opens them. How heavy each page is matters more than how many pages the publication has. Still, leave out pages that don't serve your message.
Does Maglr compress my images?
Yes. When you upload a JPEG, PNG or WebP image in the editor or file manager, Maglr compresses it and scales it down so its long side is at most 5760 pixels and its short side at most 3240 pixels. JPEG and WebP images are saved at 80% quality, and a PNG without transparency is converted to JPEG. GIFs and SVGs are not compressed. Because these limits are far larger than most images are shown at, resize large images yourself before you upload them.
