Get the right image format for government forms, passport photos, and web uploads. Compare JPG, PNG, WebP, and BMP to choose the best option for compatibility and compression.
Which Format Should You Use?
| Format | Best for | Strength | Use case |
| JPG / JPEG | Photographs | Small file size, wide compatibility | Passport photos, exam uploads |
| PNG | Logos & graphics | Lossless quality, transparency | Signatures, documents with sharp edges |
| WebP | Modern web images | Strong compression with quality retention | Website images, fast downloads |
| BMP | Legacy applications | No compression | Rare desktop tools and archives |
For exam-focused uploads, prioritize JPG unless the portal explicitly accepts PNG. WebP is great for web content but may not always be accepted by government upload forms.
When to Choose JPG
- Most exam and passport portals accept JPG without compatibility issues.
- It compresses photographs effectively while keeping file size low.
- JPG works best for real-life face photos and signature images when transparency is not required.

Frequently Asked Questions
Is JPG better than PNG for exam uploads?
Yes. JPG is typically the best choice for exam photo uploads because it balances file size and compatibility.
Should I use WebP for official documents?
Only if the portal explicitly supports WebP. Otherwise convert to JPG to avoid upload rejection.
Can I use BMP for document uploads?
BMP is rarely accepted and produces large files. Convert BMP to JPG or PNG before uploading.
