PNG vs JPG for Video Thumbnails — Which Should You Use?

Both PNG and JPG work on YouTube. The right choice depends on your frame content and whether you need to stay under the 2 MB limit.

JPG — smaller files, good for photos

Best for: talking-head frames, outdoor shots, gameplay with lots of color variation.

• Smaller file size at high quality (85–95%)
• Faster upload on slow connections
• Slight compression on hard edges and text

In FrameSnap, set JPG quality to 90% — a solid default for YouTube.

PNG — lossless, better for text and UI

Best for: screen recordings, slides, thumbnails with sharp text baked in.

• No compression artifacts on edges
• Larger files — can exceed 2 MB at 1280×720 with busy UI
• Ideal intermediate format before adding text in Canva

Quick decision guide

| Your frame contains | Use | |---------------------|-----| | Face, product photo | JPG 90% | | Screen recording, code | PNG | | Will add text in Canva later | PNG export first | | Need smallest file | JPG 85% |

YouTube’s 2 MB limit

If PNG exceeds 2 MB, either:

1. Switch to JPG at 85–90% quality, or 2. Export at 1280×720 instead of 1920×1080

YouTube recompresses all custom thumbnails anyway — starting slightly compressed in JPG is normal.

Social platforms

TikTok and Instagram covers also accept JPG/PNG. PNG is rarely required unless the platform specifies transparency (most do not for video covers).

Export both formats from FrameSnap and compare file size before upload.
