File Types - A brief summary

As an illustrator I work in lots of different formats for clients. Usually a particular file type will be specified by the client from the start of the project, other times I will help guide the client to different types of files that best suit their needs. This is a brief outline of the different types of files I use, and when I would use each type of file. All the images you see on my website are saved/uploaded as JPEG files.

JPEG File = Best for internet/website use.

JPEG’s were designed to make images smaller and easier to load quickly. A JPEG works by compressing the file by removing some image data.

JPEG’s are commonly found used on:

  • Social media & Blogs

  • Website images/online shops

  • Online portfolios

A JPEG should not be used when you need to preserve every bit of image data. .

 

PNG File = Widely used for printing

PNG preserves the artwork exactly as it exists. The file maintains the full integrity of your artwork. The file size will be larger than JPEG.

PNG also uses transparent backgrounds, which means if I am creating graphics for your website, I will save it as a PNG so no background colour will appear when you upload it to your website.

You will use PNG files predominantly for:

  • Prints/stickers

  • Companies that sell your image on items (print on demand products)

  • Images with transparent backgrounds (Logos)

TIFF file = A very large file!

TIFF files retain a gigantic amount of image data.  TIFF files are very large. TIFF files are most commonly used in professional publishing and photography. As they they store so much information, TIFF files are often used when an image may go through a lot of editing. I don’t tend to use TIFF files often unless it is required by the client.

PSD files = Used for keeping artwork editable (layers)

PSD stands for Photoshop Document.  I work in layers and can have over 100 layers in one double page illustration. A PSD file preserves layers so the file can be opened and edited again.  This is useful when collaborating with another designer and they need to add typography or additional imagery/information.

PDF: For consistency

PDFs are designed to keep layouts consistent, which makes them great for print. PDF is the most requested type of file clients ask for when setting up illustrations and artwork for print. I also use PDF’s to preserve quality and colour.
