JPEG, PNG, TIFF, WebP or RAW: Which Photo File Format Should You Use?

The same photo can exist as a RAW file, a TIFF, a JPEG or a WebP, and each version serves a different purpose.

The main differences are simple: how much image information the file keeps, how much it is compressed, whether it supports transparency, how large it is and where it will be used.

For most professional workflows, choosing the right format is less about finding the “best” file type and more about using the right one at the right stage.

RAW: the source file

A RAW file contains the image data captured by the camera sensor before the camera turns it into a finished JPEG.

That makes RAW particularly useful during editing because adjustments such as white balance, exposure and color can be changed with much more flexibility while preserving the original capture data. Adobe describes RAW files as unprocessed sensor data combined with shooting metadata.

RAW is therefore primarily a working format, not the file delivered for print, a website or social media.

Different camera manufacturers use different RAW formats. DNG is an alternative publicly documented RAW format designed to improve compatibility and long-term access.

JPEG: practical and widely compatible

JPEG is still one of the most common formats for finished photos.

It uses lossy compression, meaning some image data is discarded to reduce file size. Higher compression creates smaller files but can also reduce image quality.

Its main advantage is compatibility. JPEG works well for websites, e-commerce, presentations, email and many digital delivery situations.

Adobe describes JPEG as a common format for photographs and continuous-tone images used in web galleries, presentations and online services.

For many clients, JPEG is the most useful format for everyday final delivery.

PNG: useful when transparency matters

PNG uses lossless compression, so image data is not discarded in the same way as JPEG.

It also supports transparency, which makes it useful for logos, graphics, cut-out elements and images that need a transparent background.

For standard photography, however, PNG files are often larger than necessary.

If the image is simply a Photo with no transparency requirement, JPEG will usually be more efficient.

TIFF: high quality for professional workflows

TIFF is commonly used when image quality and compatibility with professional software are more important than file size.

It can use lossless compression and is widely supported by photo-editing and page-layout applications. Adobe describes TIFF as a flexible bitmap format with broad compatibility.

TIFF can be useful for:

professional retouching
high-quality master files
print workflows

The downside is simple: TIFF files can be large.

They are usually not the format you would upload directly to an e-commerce site or social network.

WebP: built for the web

WebP was designed for efficient web delivery.

It supports both lossy and lossless compression, as well as transparency. Modern browsers support it widely, and it can often produce smaller files than JPEG or PNG while maintaining similar visual quality.

That makes WebP particularly useful for websites where file size affects loading speed.

It is a delivery format rather than a working master file.

For a photography website, for example, a high-quality master may be kept as TIFF or another working file, while the website version is exported as WebP.

So which format should you use?

A simple way to think about it:

RAW for capture and editing.
TIFF for high-quality masters, retouching or print workflows.
JPEG for general delivery, e-commerce and digital use.
PNG when transparency or lossless graphics are needed.
WebP for optimized website delivery.

There is no single format that replaces all the others.

A professional workflow often uses several versions of the same image: one for editing, one as a master, and another optimized for the final destination.
