Unsupported file format
Check the destination’s accepted formats. Convert HEIC, AVIF or WebP to JPG for photos, or to PNG for graphics that need transparency.
File is too large
Use the form’s exact size limit. Compress to that target, then check the actual size and target status before uploading.
Invalid width, height or resolution
Check the required pixel dimensions. Resize to fit, or crop to the required aspect ratio before resizing.
Transparent background turned white
JPG fills transparent areas. Use PNG or WebP when the destination accepts it and you need to keep transparency.
Renaming the extension did not work
A new suffix does not change the file contents. Re-encode the original in a format the form accepts.
The tool cannot process the image
Try a still image within 20 MiB, 25 megapixels and 10,000 pixels per side. Process big batches in smaller groups. If the file will not open, export a fresh copy from the source app.
