# Server Module import anvil.media from PIL import Image import io @anvil.server.callable def fix_image_asset(file): # 1. Load the uploaded media img_bytes = file.get_bytes() img = Image.open(io.BytesIO(img_bytes)) # 2. The "Fix": Resize if too large (e.g., max 1920px) max_size = (1920, 1080) img.thumbnail(max_size, Image.Resampling.LANCZOS) # 3. Convert to WebP for optimization out_io = io.BytesIO() img.save(out_io, format="WEBP", quality=80) # 4. Return as Anvil Media object return anvil.BlobMedia("image/webp", out_io.getvalue(), name="fixed_image.webp") Use code with caution. 3. UI/UX Component
Creates a low-res blurred version (LQIP) to show while the main image loads.
Scales oversized images down to the maximum display size needed in your app to improve load times. # Server Module import anvil
A slider showing the original file size vs. the "fixed" file size. Status Indicator: "Fixed," "Optimized," or "Repaired." Why this is useful:
A simple area where users drop "broken" or heavy images. Convert to WebP for optimization out_io = io
Converts heavy PNG/JPG files to modern WebP or AVIF formats.
In many "Anvil" projects (or similar low-code platforms), developers often upload raw photos from cameras that are 5MB+. This feature ensures the app stays fast and responsive by "fixing" those assets automatically. UI/UX Component Creates a low-res blurred version (LQIP)
