| GitHub | Square | 400×400px+ | Transparent or solid bg |
| LinkedIn | Square | 400×400px+ | Professional bg recommended |
| Conference Badge | Passport style | Varies | Usually white bg, specific size |
| Dev.to | Square | Any | Keep it friendly |
The tool I used supports custom sizing for all of these. For ID-style photos with specific dimension requirements (passports, visas, official documents), there's a dedicated ID photo maker tutorial that covers every standard photo size and background color.
What I Learned
The biggest lesson: professional photos don't require professional photographers anymore. AI background removal and basic editing tools have democratized this completely. You just need decent lighting and 5 minutes.
I now update my profile photos every few months instead of using the same 3-year-old headshot. My conference badge photo actually looked better than the ones taken by the "professional" photographer at last year's event.
If you're a developer who's been putting off updating your online presence because you don't want to deal with photo editing, the barrier is basically zero now. Phone + AI tool + 5 minutes = done.
For more detailed comparison between different photo editing approaches (mobile apps vs desktop software vs AI tools), this Meitu vs Photoshop deep comparison breaks down what each tool is actually good for in 2026.
