Cross-Platform Publish Workflow

One source image, every platform's optimal size. The full loop from sourcing a frame (or uploading your own) through composing the master, exporting at five platform-native sizes, and validating the share card — without juggling Photoshop, Figma, or paid SaaS.

1

Source your base image

Two paths in: you either have the visual you want to use (a product shot, a graphic you designed, a frame from your own footage), or you're repurposing from a video that's already published.

For the repurposing case, paste the YouTube, TikTok, Vimeo, or Spotify URL into ThumbCrafted Grab. The tool returns every available cover size plus auto-extracted frames from the video — pick the strongest one. For the uploaded case, head straight to the editor and drag your file onto the canvas.

Compose at 1280×720

Build your master at 1280×720 in the editor. Two reasons this is the right canvas to compose at: it's YouTube-native (so the YT thumbnail is just an export), and the 16:9 aspect ratio downsamples cleanly into every other platform's size without weird crops or stretch artifacts.

Treat this canvas as your master: the strongest version of the image, with your subject, headline, and brand element all positioned where you want them. You'll resize from here, never compose from scratch per platform.

Export the master

Hit export from the editor. For a master file you're going to resize from, PNG is the safer choice — lossless, preserves any transparency, and downsamples without compounding compression artifacts. If your image has zero transparent regions and you want a smaller file, JPG at quality 95 is fine.

Save the master locally with a clear name (episode-42-master.png beats untitled.png) — you'll be loading it back in repeatedly during step 4.

Resize for each platform

Open Image Studio, drop the master in, and export at each target platform's size. The studio supports custom dimensions and remembers aspect-ratio lock per session — set it once per platform and re-export.

Five sizes covers the vast majority of where most creators publish:

Validate the share card

Before posting the link anywhere — your blog post, landing page, product page — paste the URL into ThumbCrafted Preview. It checks that the og:image is set correctly, the dimensions are large enough, the title fits each platform's truncation limit, and the image won't crop awkwardly on Twitter's tighter 1.91:1 large card.

If anything fails, the Preview Debug Workflow walks through the diagnose → fix → re-scrape loop for broken share cards specifically.

Common pitfalls

Never start small and upscale Always compose at the largest target size and downsample to the smaller ones. Upscaling introduces blur and edge artifacts that no platform compression can fix. 1280×720 → 1080×1080 is fine; 800×450 → 1280×720 is not.
Square and 9:16 may need recomposition, not resize Cropping from 16:9 down to a 1:1 square or a 9:16 vertical can chop off your subject or headline. For those two formats, sometimes the right move is to recompose in the editor with the new aspect ratio rather than crop-resize from the master.
Text size doesn't survive equally across sizes A headline that reads cleanly at 1280×720 may be illegible at 1080×1080 when the canvas shrinks and the text is forced smaller. Verify each export at actual size — and consider a separate, larger-headline composition for vertical formats.
1080×1920 covers both IG story and TikTok cover One export, two destinations. Both platforms use the same 9:16 vertical at 1080×1920 (TikTok actually crops in slightly more aggressively in-feed, so keep critical content centered). Don't waste a separate export.

Frequently asked

Why 1280×720 as the master instead of 1920×1080?
1280×720 is YouTube's documented native thumbnail size — that's the size YT serves to viewers. Composing at this size means your YouTube export is 1:1 from master, no scaling. 1920×1080 looks "higher quality" but YouTube downsamples it to 1280×720 anyway, so you're just doing the resize twice (once on your end, once on theirs). Master at the lowest actual delivery size for your largest target.
Can I use one image for both Instagram square and Facebook share?
Technically yes, but the aspect ratios are different (1:1 vs 1.91:1), so the Facebook version will have empty top and bottom bars OR you'll lose the left and right edges of the Instagram version. Two separate exports almost always look better than one stretched/cropped compromise.
What about YouTube Shorts and Reels covers?
Both Shorts and Reels render covers in 9:16 vertical (1080×1920) — the same export covers TikTok, IG Reels, IG Stories, YT Shorts, and Facebook Reels. The single 9:16 export from step 4 takes care of all five.
Do I need to optimize file size before uploading?
YouTube and the major social platforms re-encode everything you upload, so you don't need to pre-compress aggressively. But the og:image you put on your own site should be optimized — under 1 MB ideally — since browsers fetch it on every page load. Image Studio has a quality slider for JPG and WebP that handles this in one step.
What if my share card preview is still wrong after all this?
If you've shipped the new og:image to your site but the share card still looks broken on Facebook or Twitter, jump to the Preview Debug Workflow — it covers the re-scrape step that forces each platform to refresh its cached preview.
