How to Choose the Right Image Format
A simple decision guide to picking the best image format every time — based on the type of image, transparency, and where it will be used.
With so many image formats around, choosing the right one can feel confusing. But a few simple questions will point you to the best format almost every time.
Start with the type of image
Is it a photograph or a graphic? Photos with smooth color gradients compress best as JPG or WebP. Graphics with flat colors, sharp edges or text — logos, icons, screenshots — look best as PNG or lossless WebP, which keep edges crisp.
Do you need transparency?
If part of the image must be see-through, you need a format with an alpha channel: PNG, WebP or AVIF. JPG cannot store transparency and will fill those areas with a solid background.
Is it for the web or for print?
For the web, prioritize small files: WebP or AVIF. For print or archiving, prioritize quality: a lossless format such as TIFF or PNG is the safer choice.
Quick decision checklist
- Photo for the web → WebP (or AVIF with a fallback).
- Photo for sharing anywhere → JPG.
- Logo, icon or screenshot → PNG, or SVG if it is a vector.
- Needs transparency → PNG, WebP or AVIF.
- Print or archive master → TIFF or PNG.
Once you know the format you want, converting is instant and private here — your files never leave your browser.
