What characters should I avoid in clipart file names?

Skip \ / : * ? " | entirely. Windows won't let you save a file name containing any of them, and Mac blocks the colon specifically because macOS uses it internally as a path separator. Leaving all of them out means a name that works on your system will not misbehave on someone else's.

Should I use hyphens, underscores, or spaces in file names?

Hyphens, with everything lowercase. Spaces turn into %20 the moment a file is shared as a link, and Google's own guidance for naming image files recommends hyphens over underscores for exactly that kind of small, avoidable friction.

Do matching PNG and SVG files need the same name?

Yes, ideally. Give both formats of the same design the identical base name and change only the extension, like farm-animals-03.png and farm-animals-03.svg, so a buyer can tell at a glance which files go together.

Does a file's name affect Etsy search rankings?

Not directly. Etsy's search ranking runs on your listing title, tags and description, not on the literal name of the file inside the zip. Good file names are about the experience after someone buys, not about getting found before they do.

How should I number files within a set?

A two-digit number starting at 01 works for almost any pack size: farm-animals-01, farm-animals-02, and so on. It keeps the set in a sensible order and leaves room to grow without the numbering looking uneven.

Do I have to rename every file by hand?

No. Once you've settled on a pattern, a tool that renames a whole folder in one pass applies it to every file at once, which is far faster than typing out names one by one, especially when your AI tool or camera hands you a folder of files like IMG_4021.png to begin with.

How to Name Your Clipart Files Like a Pro

Your file names are invisible until a buyer unzips your pack, and then they are the first thing that reads as either professional or rushed. But naming clipart well is not only a style choice. Get the characters wrong and a file can behave differently the moment it lands on a different operating system than the one you made it on.

Here are the actual naming rules worth knowing, the ones about compatibility and consistency, not just a preference for tidy-looking names.

It's not just style, it's compatibility

A file name that looks fine on your own computer can misbehave the moment it reaches somebody else's. Windows will not let you save a file name containing any of these characters: \ / : * ? " < > |. Mac blocks just one, the colon (:), because macOS's file system uses it internally to separate folders in a path. The simplest fix is to leave all of them out of your clipart file names from the start, so nothing you name on your own system ever trips up on someone else's.

Hyphens and lowercase, not spaces or underscores

Spaces and underscores are not banned anywhere, but they carry small annoyances. A space in a file name turns into %20 the moment that file is ever shared as a link, which is part of why Google's own guidance for naming image files recommends hyphens between words instead, along with lowercase letters throughout. Farm-animals-03 reads cleanly everywhere. Farm_Animals_03 or "Farm Animals 03.png" both work, technically, right up until one of them doesn't.

Etsy's search ranking runs on your listing title, tags and description, not on the literal name of the file inside the zip. Naming files well is about the experience after a buyer opens your pack, not about getting found before they buy it.

Keep multiple formats in sync

If a pack includes more than one format, say a PNG and an SVG version of the same design, give both files the exact same base name and change only the extension: farm-animals-03.png sitting next to farm-animals-03.svg. A buyer can then tell at a glance which files belong together, instead of guessing whether an oddly named SVG matches the PNG they already opened.

A pattern that still makes sense at 500 files

A single pack is easy to keep tidy by hand. A shop with dozens of packs and hundreds of files is not, unless every file follows the same simple pattern from day one.

Pick a short theme word for the set, like farm-animals or spring-floral.
Add a two-digit number for each design, starting at 01.
Keep every word lowercase and separate them with hyphens, never spaces or underscores.
Leave out the characters Windows and Mac won't allow: \ / : * ? " < > |.
Give matching PNG and SVG files the same base name, and change only the extension.

farm-animals-01.png, farm-animals-02.png, farm-animals-03.png: a whole set, instantly readable.
spring-floral-01.svg next to spring-floral-01.png: obviously the same design, two formats.
IMG_4021.png or grid-output-3.png: exactly what most AI tools and cameras hand you by default, and exactly what to rename before it ships.
