The Complete Guide to Beautiful Code Screenshots

Python is one of the most-shared programming languages on social media. With SnapPolish-Canvas you can turn any Python script into a share-worthy image in under 30 seconds.

1. Paste your code — Open the editor and paste your Python snippet into the code area.
2. Pick a dark theme — Dark backgrounds create higher contrast against Python's colourful syntax, making keywords like def, import, and class pop.
3. Export — Click "Export / Preview" and choose the format that matches your platform (Square for Instagram, Landscape for Twitter).

Pro tip: use the custom background feature to match your brand colours for a consistent feed aesthetic.

Whether you're sharing a clever React hook or an Express middleware, JavaScript snippets perform exceptionally well on Twitter/X. SnapPolish is designed to make your JS exports look crisp at any resolution.

• Resize the window — Drag the code window handles to eliminate trailing whitespace and create clean line breaks.
• Use Landscape mode — Twitter's timeline favours wide images. The Landscape (16:9) export fills the feed perfectly.
• Add your brand — Upload a custom logo (Pro) so viewers always know who wrote the snippet.

The result is a high-resolution, watermarked image ready for viral engagement.

Instagram is a visual-first platform, and beautifully formatted code images can drive serious engagement from the design community.

• Square mode — Select the 1:1 Square export to match Instagram's native post dimensions.
• Vibrant gradients — Pair your HTML/CSS snippets with eye-catching gradient backgrounds (Pink-Purple or Neon Fire work great).
• Tip cards — Keep your code short (5-10 lines) and focus on a single CSS trick per post for maximum saves and shares.

Combine this with SnapPolish's viral hook generator to craft the perfect caption.

Backend languages like Rust and Go are gaining massive traction in the developer community. SnapPolish supports full syntax highlighting for both, so your systems-level code looks just as polished as front-end snippets.

• Rust — The dark theme pairs beautifully with Rust's ownership syntax and lifetime annotations.
• Go — Go's clean, minimal syntax shines on light backgrounds. Try the "Emerald Blue" gradient for a fresh look.
• Export all formats — Use Batch Export (Pro) to generate Square, Landscape, and Portrait versions in one click.

LinkedIn carousels are one of the highest-engagement formats on the platform. Code-focused carousels regularly outperform text posts by 3-5×.

1. Portrait mode — Select the 9:16 Portrait/Story export. This creates tall images that look native in carousel swipe format.
2. High resolution — SnapPolish exports at full resolution so your code stays razor-sharp even after LinkedIn's compression.
3. Batch export — Create multiple slides with different code sections, then upload them as a carousel document.

Pair each slide with a numbered caption for maximum readability and engagement.
