JPG vs PNG vs WebP: Which Should You Use?
Photos, logos and the web each want a different answer. Here's the rule.
Use JPG for photographs, PNG when you need transparency or crisp text and lines, and WebP for anything on the web — it's typically 25–35% smaller than JPG at the same visual quality and supports transparency too. The one-line rule: WebP on your website, JPG when emailing photos, PNG for logos and screenshots.

Why PNG photos are the most common mistake
Look at the table: the same photo is ~6.7× larger as PNG than as JPG. That's not a quirk — it's the formats working as designed.
PNG is lossless: it reproduces every pixel exactly, which is essential for a logo with hard edges and terrible for a photo where every leaf and skin pore is unique data it must faithfully store. JPG is lossy: it discards high-frequency detail your eye can't resolve anyway.
The practical damage is real. A page with six PNG photos instead of JPGs can carry 15 MB instead of 2 MB — several seconds of load time on mobile, and page weight affects both rankings and conversions.
When PNG is the right call
PNG wins whenever exactness matters more than size:
- Logos and icons — JPG smears artefacts around hard edges, and there's no transparency, so you get a white box around your logo.
- Screenshots with text — JPG makes small text fuzzy. PNG keeps it razor-sharp.
- Anything with a transparent background. JPG simply cannot do it.
- Images you'll edit repeatedly. Every JPG re-save loses more quality; PNG doesn't degrade.

Is WebP safe to use yet?
Yes. WebP is supported by every current browser — Chrome, Firefox, Edge, Opera, and Safari from version 14 (2020) onward. Effective support is well above 95% of global traffic.
Where WebP still isn't the answer: files leaving the web. Older desktop software, some print workflows and a few corporate systems don't accept it. If you're emailing a photo to a client or sending something to a printer, send JPG. If it's going on a web page, send WebP.
The safest pattern for a website is a <picture> element with a WebP source and a JPG fallback — modern browsers take the small file, everything else still works.

Frequently asked questions
Is WebP better than JPG?
For the web, yes. WebP files are typically 25–35% smaller than JPG at the same visual quality, and WebP also supports transparency and lossless mode, neither of which JPG can do. Every current browser supports it, including Safari 14+. The exception is files leaving the web — for email attachments or print, JPG remains more universally accepted.
Should I use PNG or JPG for photos?
JPG, almost always. PNG is lossless, so the same photo can be 5–7× larger than the JPG version with no visible benefit — a 420 KB JPG can be a 2.8 MB PNG. Save PNG for logos, screenshots, line art and anything needing a transparent background, where its pixel-exact reproduction actually matters.
Does converting JPG to PNG improve quality?
No. Quality lost to JPG compression is gone permanently; converting to PNG just stores the already-degraded pixels in a much larger file. You get the file size penalty with none of the benefit. The only reason to convert a JPG to PNG is if you need transparency or you're about to do repeated edits and want to avoid further generational loss.
Which format is best for a website logo?
SVG if you have it — it's vector, so it scales to any size and stays tiny. Otherwise PNG, because you need the transparent background and crisp edges that JPG destroys. WebP works well too and is smaller than PNG, though PNG's universal support makes it the safer default for a logo that gets reused in emails, decks and documents.
