PNG vs JPG: Which Image Format Should You Use? | Bsbshs
Open the tool →PNG or JPG — which should you use? The right choice depends on what's in the image and where it's going. Here's a clear, practical comparison so you always pick the best format.
The core difference
JPG uses lossy compression: it discards data your eye barely notices to make small files. It's ideal for photographs. PNG is lossless: it keeps every pixel exactly and supports transparency, making it ideal for graphics, logos, screenshots, and anything with sharp text or lines.
When to use JPG
- Photographs — smooth colour gradients compress well with no visible loss.
- Uploads with size limits — JPG is far smaller.
- Sharing and email — smaller files send faster.
When to use PNG
- Logos and graphics — crisp edges stay sharp.
- Transparency — PNG can have a see-through background; JPG cannot.
- Screenshots with text — text stays clean and readable.
- Images you'll edit repeatedly — lossless means no quality loss each save.
File size difference
For the same photo, JPG is usually several times smaller than PNG. For a simple graphic with few colours, PNG can actually be smaller. Match the format to the content for the best size and quality.
Converting between them
You can convert either way in your browser. Convert PNG photos to JPG to save space; convert to PNG when you need transparency or maximum sharpness. Nothing is uploaded — it all happens on your device.

Summary
Use JPG for photos and size-limited uploads, and PNG for logos, screenshots, transparency, and sharp text. Matching the format to the content gives you the best balance of quality and file size — and you can convert either way privately in your browser.
