Compress an image for a 100KB upload limit
A 100KB cap usually allows better quality than 20KB or 50KB, but many forms still reject large camera photos. Use this page to reduce file size while keeping enough detail for photos, documents, and general form images.
100KB compression checklist
- Resize oversized camera images before compression for a cleaner result.
- Choose a widely accepted output such as JPG unless the form says otherwise.
- Confirm text, faces, or document details remain readable after compression.
- Upload the result only after the final file size is at or below 100KB.
