A podcast cover rarely stays in one place. The square artwork submitted to a hosting platform may also appear as a tiny tile in a listening app, a large image on an episode page, and a cropped card in a newsletter. Exporting one enormous PNG for every destination is simple, but it creates slow pages and still does not prove the artwork will read at thumbnail size.
The better approach is to treat the Figma file as the visual source and create a small, named set of delivery assets. TinyImage can compress and convert those exports inside Figma, but the important decisions still happen before export: what must remain legible, which variants are genuinely needed, and what each destination accepts.
Start with the smallest place the cover will appear
Open the artwork in Figma and zoom out until it is roughly the size of a podcast tile on a phone. If the show name disappears, a guest portrait becomes unrecognizable, or a thin border turns into noise, a sharper export will not solve the problem.
At thumbnail size, prioritize:
- one dominant subject or mark;
- short, high-contrast title text;
- generous space around the edges;
- shapes that survive reduction;
- a composition that does not depend on fine print.
Episode-specific artwork can include a guest name or topic, but do not make that text the only way to distinguish the episode. Some apps display the show cover instead, while others crop or shrink episode art aggressively.
Build a compact export matrix
Do not create a different master frame for every channel. Keep one approved square master, then create only the derivatives that have a real publishing job.
| Asset | Purpose | Sensible review |
|---|---|---|
| Directory master | Podcast host and listening directories | Square, high resolution, no clipping |
| Web image | Episode and show pages | Lightweight and sharp at rendered size |
| Social card | Launch and episode promotion | Check platform crop and text safe area |
| Email thumbnail | Newsletter modules | Test at the actual narrow email width |
Confirm current pixel dimensions, file-size ceilings, color requirements, and accepted formats in each destination before exporting. Platform rules change; a filename such as show-cover-directory-v4 is not evidence that the file still meets them.
Choose formats by destination
Use the format the receiving system supports, not the newest format by default.
JPEG is often suitable for photographic cover art because it can be compressed efficiently. PNG is useful for flat graphics, hard edges, and transparency, although complex PNGs can become heavy. WebP or AVIF can be useful for a website when its publishing stack supports them, but they may not be accepted by podcast directories. Keep the directory upload separate from web-performance derivatives.
If you need a refresher on the tradeoffs, the SVG, PNG, and WebP export guide explains how image content affects the choice. Podcast artwork is normally raster output even when the source logo is vector.
Export and compress without losing the master
Name the Figma frame as the canonical artwork and preserve it at full quality. Export copies from that source instead of repeatedly compressing an already compressed file.
With TinyImage, select the approved frames, choose the required formats, and apply a target file size where the destination has a hard limit. A target is especially useful for web and email assets because it replaces repeated quality-slider guesses with a clear budget. Batch export the derivatives together so they come from the same approved design state.
A practical naming pattern is:
show-or-episode + destination + dimensions + revision
For example: field-notes-directory-3000x3000-v3.jpg and field-notes-web-1200x1200-v3.webp. Dimensions in the name help publishers avoid uploading the thumbnail as the master. The revision identifies the approved artwork without relying on “final-final”.
Review pixels and context
An exported file can look perfect at 100% and fail in use. Review every derivative in four ways:
- Open the file outside Figma and confirm its dimensions, format, and file size.
- Inspect faces, gradients, small type, and high-contrast edges for compression artifacts.
- Place it in a realistic tile, episode page, email module, or social preview.
- Check the smallest rendition on both standard- and high-density screens.
Watch for muddy dark gradients, halos around type, banding behind portraits, and sharpening that makes skin or logos look brittle. If the export misses the quality bar, simplify the artwork or allow a larger budget rather than silently changing to a format the destination cannot use.
Color also deserves a deliberate check. If the artwork changes noticeably between Figma, the exported file, and the publishing preview, review the color-profile choice and the destination’s image processing. The Figma export color-profile checklist covers that handoff in more detail.
Give publishers a handoff they can verify
Deliver a short manifest beside the files. For each asset, record its intended destination, dimensions, format, approximate size, and approved revision. Note which file is the directory master and which files are replaceable derivatives.
Before the release goes live, ask the publisher to verify:
- the correct show or episode received the artwork;
- the directory did not reject or silently recompress it badly;
- the title remains readable in a small tile;
- no platform crop removes essential content;
- the page image does not create an avoidable performance penalty;
- cached previews have refreshed where the artwork changed.
TinyImage handles the repetitive export, conversion, compression, and naming work. It cannot decide whether a listening app has cached an old cover or whether a guest approved their portrait. Keep those human checks in the release process, and podcast artwork becomes a controlled publishing asset instead of one mysterious square file passed between teams.
