FORMAT COMPARISON
PNG vs JPG vs SVG, settled.
The three formats every project juggles, resolved by three questions: Is it drawn or photographed? Does it need transparency? Will it be scaled? Answer those and the format picks itself – the table and scenarios below make it automatic.
The three-question test
Drawn or captured? Transparency needed? Scaling expected? Three answers, one format – it never takes longer than five seconds.
Scenario cheat sheet
Logo, hero photo, screenshot, social card, favicon, print asset – the right call for each, with reasons, below.
Every common scenario, decided
- Website logo → SVG (sharp, tiny, themeable)
- Hero/product photo → JPG or WebP (photo compression)
- Screenshot in docs → PNG (lossless text edges)
- Icon set → SVG (one file, all sizes, recolorable)
- Photo needing transparent cutout → PNG (alpha) – WebP where accepted
- Email graphics → PNG at 2× (clients strip SVG)
- Social media post → JPG/PNG per platform spec (rasters only)
- Favicon → SVG + ICO fallback
- Print logo handoff → SVG master → vector PDF
The mistake matrix – what goes wrong with the wrong pick
Logo as JPG: white box, edge halos, blur at scale – the most common branding error on the internet. Photo as PNG: 5–10× the bytes for invisible benefit, slow pages. Photo as SVG: a posterized art piece where a photo should be. Screenshot as JPG: smeared text. Each mistake is reversible with the converters above – but knowing the test, you won’t make them.
The three formats compared
| SVG | PNG | JPG | |
|---|---|---|---|
| Type | Vector | Raster, lossless | Raster, lossy |
| Best for | Logos, icons, UI graphics | Screenshots, transparency, crisp raster | Photographs |
| Scaling | Infinite | Degrades | Degrades |
| Transparency | Yes | Yes | No |
| Photo efficiency | Poor (posterizes) | Poor (huge files) | Excellent |
| Graphic efficiency | Excellent | Good | Poor (artifacts) |
| Editable later | Fully | Pixels only | Pixels only, degrades |
| Universal uploads | Often blocked | Yes | Yes |
VERDICT
Drawn → SVG. Photo → JPG (or WebP). Pixel-content needing transparency or sharpness → PNG. When a platform blocks SVG, export PNG at 2× as the stand-in.
FAQ
Frequently asked questions
Which is best – PNG, JPG, or SVG?
Wrong question – they’re for different content. Drawn graphics → SVG, photos → JPG, lossless pixel content (screenshots, transparent cutouts) → PNG. The three-question test above settles every case.
Which format is smallest?
Depends on content: a logo is smallest as SVG (KBs), a photo is smallest as JPG/WebP. Forcing the wrong format inflates size dramatically in both directions.
What about WebP and AVIF?
Modern replacements for the raster side: WebP/AVIF beat both PNG and JPG at their own jobs where accepted. The vector side remains SVG. Comparison: SVG vs WebP.
Why do some sites block SVG uploads?
SVG is scriptable XML, so unsanitized uploads are a security risk. Platforms block the format wholesale; that’s when PNG at 2× becomes your delivery format.
