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

October 20, 2026

Choosing an image format sounds technical, but it comes down to what is in the picture and where it will be used.

JPG (JPEG)

Best for: photographs and images with smooth colour gradients.
How it works: lossy compression that throws away fine detail to save space.
Weak at: sharp lines and text (they can look smudgy) and transparency (not supported).

PNG

Best for: logos, icons, screenshots, diagrams and anything with transparency.
How it works: lossless compression, so every pixel is preserved.
Weak at: photographs, where files become very large.

WebP

Best for: websites that want smaller files. It can store photos (lossy) or graphics (lossless) and supports transparency.
How it works: modern compression that is typically smaller than JPG or PNG at similar visual quality.
Weak at: compatibility with some older software, although current browsers support it widely.

Quick decision guide

  • A photo for a website: WebP (or JPG if you need maximum compatibility).
  • A logo with a transparent background: PNG or WebP.
  • A screenshot with text: PNG.
  • A photo to print or share by email: JPG.
  • An image you will edit again and again: PNG, so no detail is lost between saves.

Converting between formats

You can change formats with JPG to PNG, PNG to JPG, WebP Converter or the general Image Converter. Two things to remember: converting PNG to JPG replaces transparency with a solid colour, and converting JPG to PNG does not restore detail that was already discarded; it only stops further loss.

What about HEIC and SVG?

Photos from iPhones are often stored as HEIC, which many websites and Windows programs cannot open. Convert them with HEIC to JPG. SVG is a vector format for simple graphics that scale to any size without blurring; you can preview one with SVG Viewer or turn it into a bitmap with SVG to PNG.

Frequently asked questions

Is WebP always better than JPG?

It is usually smaller at similar quality, but JPG is understood by absolutely everything. For files you will email or open in older software, JPG is the safe choice.

Why is my PNG so large?

PNG is lossless, so photos stored as PNG are big. If transparency is not needed, convert photographs to JPG or WebP.

Does converting JPG to PNG improve quality?

No. The detail lost when the JPG was made is gone. The PNG simply prevents further loss when you save again.

Which format is best for printing?

Use the highest-quality original, often a high-quality JPG or a lossless format such as PNG or TIFF, at the resolution your printer requires.

Key takeaways

  • Photos: JPG or WebP. Graphics and transparency: PNG or WebP.
  • Converting does not restore lost detail.
  • Keep a lossless master for images you edit often.
