PNG vs JPEG vs WebP for video frames
The best format depends on what is inside the frame and what happens next. Resolution and format solve different problems: dimensions control pixel count, while encoding controls how those pixels are stored.

JPEG: dependable for photographs
JPEG is broadly compatible and efficient for natural scenes. Use it for thumbnails, reference photos, and ordinary camera frames when transparency is unnecessary.
Its lossy compression can create halos around text and sharp graphics. Keep a high-quality master if the frame will be edited repeatedly.
PNG: crisp and lossless
PNG is the safest option for slides, interfaces, diagrams, and frames with small text. It preserves hard edges and repeated saves do not introduce additional lossy compression.
The cost is file size. A photographic PNG contact sheet can become unnecessarily large.
WebP: efficient modern delivery
WebP often provides a useful quality-to-size balance for websites and modern applications. It can support both lossy and lossless encoding, though the exact export behaviour depends on the tool.
Check compatibility with the publishing, editing, or document system receiving the image. JPEG remains the least surprising handoff format.
Quick decision rule
Choose JPEG for photographic sharing, PNG for text-heavy or lossless editing, and WebP for web delivery when the target supports it.
The source quality still matters more than the extension. No output format repairs an out-of-focus or motion-blurred frame.
