Image Upload and Display Performance Issues in Base44
Images in your Base44 app are causing performance problems. Uploading images takes a very long time or fails entirely, and pages with multiple images load extremely slowly. Users with slower internet connections experience the worst effects, with images taking 10+ seconds to appear.
Image-heavy apps (portfolios, product catalogs, real estate listings, etc.) are particularly affected. Each full-resolution image can be several megabytes, and a page displaying 20+ images may need to download 50MB or more of data.
Thumbnail views that should show small preview images are instead loading the full-resolution versions, wasting bandwidth and dramatically slowing down the page.
Error Messages You Might See
Common Causes
- Images are stored and served at their original full resolution without compression or resizing
- No thumbnail generation is configured, so gallery views load full-size images
- Lazy loading is not enabled, so all images on the page load simultaneously on page open
- The image storage location has slow delivery (no CDN or edge caching)
- Image upload has no file size limit, allowing users to upload very large files
How to Fix It
Compress images before uploading using a tool like TinyPNG or Squoosh. Aim for images under 200KB for gallery/list views and under 1MB for full-screen display.
If Base44 supports lazy loading, enable it so images only load as the user scrolls to them. This dramatically reduces initial page load time for image-heavy pages.
For apps that handle many images, a developer can implement automatic image compression on upload, generate thumbnails at multiple sizes, and configure a CDN for fast delivery.

I've been working at a large software company named Kainos for 2 years, and mainly specialise in Platform Engineering. I regularly enjoy working on software products outside of work, and I'm a huge fan of game development using Unity. I personally enjoy Python & C# in my spare time, but I also specialise in multiple different platform-related technologies from my day job.

Get HelpFrequently Asked Questions
Why are images loading slowly in my Base44 app?
Images are likely being served at full resolution. Compress them before uploading (aim for under 200KB for thumbnails) and enable lazy loading if available.
How do I optimize image uploads in Base44?
Set a maximum file size for uploads, compress images before uploading, and consider using an external image CDN service for faster delivery.
