Image Upload Failing or Corrupted in Lovable
When users try to upload images in your Lovable app, the upload either fails entirely, succeeds but the image appears broken or corrupted, or the image uploads but never displays correctly on the page.
Image uploads are a core feature for many apps — profile pictures, product images, gallery uploads. When they break, users can't complete essential tasks and the app feels unreliable.
The issue may appear in different ways: a spinner that never completes, an error message after selecting a file, a broken image icon where the photo should appear, or images that upload fine on desktop but fail on mobile.
Error Messages You Might See
Failed to upload image
Payload too large
Error: new row violates check constraint
The resource could not be loaded
net::ERR_FAILED 413
Common Causes
- File size too large — Mobile phone photos can be 5-15MB, exceeding default upload limits
- Wrong MIME type — HEIC images from iPhones aren't handled, or the server expects specific image formats
- Storage bucket not configured — Supabase storage bucket doesn't exist or has wrong permissions
- Missing image transformation — Images aren't resized before upload, causing timeout on large files
- Base64 encoding issues — The app converts images to base64 for database storage, hitting text column size limits
How to Fix It
- Check Supabase storage configuration — Verify the bucket exists, is set to public (if images need to be displayed), and has correct RLS policies
- Add client-side image compression — Use a library like browser-image-compression to resize images before upload
- Handle HEIC format — Add HEIC to JPEG conversion for iPhone users using heic2any library
- Increase upload size limits — Configure your server and Supabase to accept larger files if needed
- Verify the image URL — Check that the stored URL is correct and accessible by opening it directly in a browser

Get HelpFrequently Asked Questions
Why do iPhone photos fail to upload?
iPhones save photos in HEIC format by default, which many web apps don't support. You need to either convert HEIC to JPEG before upload or configure your storage to accept HEIC files.
Should I store images in the database or storage?
Always use dedicated storage (like Supabase Storage or S3). Storing images as base64 in the database is slow, expensive, and hits size limits quickly.
