Best Image Formats for Clean Text Capture

When PNG, JPG, WEBP, BMP, or PBM makes sense for text extraction and how each format affects sharpness.
The best format depends on where the image came from. Screenshots usually work best as PNG, while photos can still perform well as high-quality JPG.
When PNG is the better choice
PNG keeps edges crisp, which helps with app screenshots, UI labels, and exported slides. Thin fonts stay cleaner than they do in compressed formats.
When JPG is good enough
JPG is fine for camera photos when the source is already photographic. Problems show up when the file is small, over-compressed, or repeatedly re-saved.
- Use PNG for screenshots and interface captures.
- Use high-quality JPG for camera photos of documents.
- Re-export poor images instead of repeatedly uploading the same compressed file.
