Is PNG better quality than JPG?

PNG keeps every pixel, so it's better for text, logos and graphics. For photos, a good-quality JPG looks the same to the eye at a fraction of the size.

Which format has the smallest file size?

For photos, usually WebP, then JPG. For graphics with flat colours, PNG or lossless WebP. HEIC is also small but less widely supported.

Does converting an image reduce its quality?

Converting to a lossy format (JPG, lossy WebP) can lose a little detail depending on the quality setting. Converting to PNG loses nothing, but can't bring back detail that's already gone.

Can I convert many images at once?

Yes. The Image Converter converts up to 30 images in one go, in your browser.

JPG vs PNG vs WebP vs HEIC: Which Image Format Should You Use?

Updated 28 September 2026 · 3 min read

The same picture can be a 300 KB JPG, a 2 MB PNG or a 200 KB WebP. None of them is "best" — each format is built for a different kind of image. Choosing well keeps files small, keeps logos crisp and avoids the "can't open this file" problem. When you need to switch, the Image Converter converts between JPG, PNG and WebP in your browser.

The short answer

Photos: JPG for sharing anywhere, WebP for websites.
Logos, icons, screenshots and anything with text: PNG (or WebP).
Anything that needs a transparent background: PNG or WebP — never JPG.
iPhone photos (HEIC): convert to JPG before sending to someone on Windows or uploading to a website.

The formats compared

Format	Compression	Transparency	Best for	Watch out for
JPG / JPEG	Lossy	No	Photos, sharing, printing	Blurry edges around text; quality drops each time it's re-saved
PNG	Lossless	Yes	Screenshots, logos, graphics, editing	Very large files for photos
WebP	Lossy or lossless	Yes	Websites — photos and graphics	Some older software can't open it
HEIC / HEIF	Lossy	Yes	iPhone camera photos	Limited support on Windows and many websites
GIF	Lossless, 256 colours	Yes (on/off)	Simple animations	Poor for photos; big files
SVG	Vector (not pixels)	Yes	Logos and icons that scale to any size	Not for photos

Lossy vs lossless

Lossy formats (JPG, lossy WebP, HEIC) throw away detail your eye is unlikely to notice, which is why photos become so much smaller. Lossless formats (PNG, lossless WebP) keep every pixel exactly, which matters for sharp text, flat colours and images you'll keep editing. Saving a JPG again and again slowly degrades it; a PNG can be re-saved forever without change.

Why WebP is worth using on websites

WebP was designed for the web. Google's published tests found lossy WebP files around a quarter to a third smaller than JPGs of similar quality, and it supports transparency too. Every current major browser displays it, so for images on your own site it's usually the best choice. Keep a JPG copy for email and older software. The JPG to WebP converter does the switch.

Why your iPhone photos are HEIC

Since iOS 11, iPhones save photos as HEIC by default because it stores similar quality in roughly half the space of JPG. Apple devices open it without trouble, but many Windows PCs, websites and upload forms don't. Converting with HEIC to JPG fixes that — our HEIC to JPG guide also shows how to make your iPhone save JPGs instead.

Converting between formats

PNG → JPG: smaller files for photos and screenshots of photos. Transparent areas become white. Use PNG to JPG.
JPG → PNG: useful before editing or adding transparency, but it won't restore detail the JPG already lost — and the file gets bigger. Use JPG to PNG.
Anything → WebP: smaller images for your website. Use the Image Converter.
