What Uses Bandwidth on a Webflow Site and How to Find It

Why it matters

Webflow sets bandwidth limits per site, based on your Site plan. If you go over, your plan can change.

Webflow's surge protection means Basic and Premium Site plans (and legacy CMS or Business plans) are not charged for going over in one billing month. If you go over again the next month, your plan or bandwidth tier is upgraded at the start of the following billing month. The upgrade is based on the lower of your last two months' usage.

Here is what counts toward bandwidth:

• Page loads. Each load sends the page and its assets.
• Bots. Webflow counts all user agents, bots included.
• Status codes. 200s, 404s and redirects all count.

Analytics, embeds and social widgets generally do not use your bandwidth. They can still slow the page down.

How to check it

1. Open Site usage. Go to Site settings, then Site usage.
2. Pick a date range. You can choose up to 366 days. The earliest date is April 1, 2024.
3. Read the summary tiles. They show Total used, Avg per day, Peak day, Active traffic and Trend.
4. Check the asset donut chart. It splits asset bandwidth into Images, Videos, Fonts, Scripts, Stylesheets and Other.
5. Open the assets table. Switch between By top assets and By asset type. Click View details to search, filter by Top bandwidth or Biggest movers, and export with Export CSV.
6. Read the Where column. It shows whether an asset lives in a Font, CMS, Assets or Code. An em dash means Webflow could not match the file.
7. Know the limits of the data. The dashboard does not separate bot traffic. Webflow's article also describes breakdowns by asset, not by page. If total bandwidth is high and no single asset stands out, bots or page-load volume may be the reason.

How to fix it in Webflow

1. Start with the biggest asset. Use the Top bandwidth filter first. Then check Biggest movers for anything that changed recently.
2. Shrink images. Compress images in the Assets and CMS panels. Convert them to WebP. Resize images over 2,000 px. Webflow suggests inline images with object-fit instead of background images.
3. Replace large GIFs. Webflow recommends MP4 video for GIFs over 1 MB.
4. Move or compress video. Compress videos before uploading. You can also host them on YouTube, Vimeo or Cloudflare Stream, or use a Marketplace app such as Flowdrive or Vidzflow.
5. Trim fonts. In Site settings, then Fonts, delete unused fonts. Remove unused weights and styles.
6. Clean up code. Minify HTML, CSS and JavaScript. Remove unused styles and interactions. Move page-specific scripts from Site settings, Custom code, to that page's Page settings, Custom code.
7. Delete unused assets. Remove them from the Assets panel.
8. Handle bots with care. Use robots.txt rules to block unwanted crawlers. You can also use the Traffic control toggles in Site settings, SEO, Indexing. Webflow warns that blocking search engine or AI bots may reduce your visibility in traditional and AI search.
9. Check again. Return to Site usage later and compare the Trend tile.

FAQ

Do 404 errors and redirects use bandwidth?

Yes. Webflow counts responses with any status code, including 200s, 404s and redirects.

Do analytics scripts and embeds use my Webflow bandwidth?

Generally no. Webflow says third-party services do not usually affect bandwidth. They can still slow pages down.

Can I see which bots are using my bandwidth?

Not in the dashboard. Webflow counts traffic from all user agents and does not separate bot traffic. You can use robots.txt to allow or block specific bots.
