What file size and format work best for face swap uploads?
Formats and sizes
Most apps accept common image formats such as JPEG and PNG. JPEG files are smaller but can show compression artifacts if saved at low quality. PNG files keep more detail but can be much larger. HEIC photos from iPhones may need converting before upload if the app does not support them.
There is no single perfect size, and limits vary by app. A face that fills a reasonable part of a clean, high-quality photo usually matters more than the raw file size.
- Use JPEG or PNG when the app supports them
- Keep the face at a readable size in the frame
- Avoid heavily compressed screenshots
- Convert HEIC files if an upload fails
Video uploads
Video files have their own limits on length, resolution, and frame rate. Long, high-resolution clips take more processing time and may fail on slower connections. Trimming the clip to the part you need often saves time and reduces errors.
Check the app's stated limits before uploading, since these change over time.
Renaming a file does not change its quality, so focus on resolution and compression settings. Many phones let you choose a higher quality setting for photos before you take them.
Common mistakes
- Uploading a heavily compressed image and expecting sharp output.
- Sending a long, high-resolution video before testing a short sample.
