The short answer

To change small case to uppercase in ordinary text, paste the text into an online case converter, choose the uppercase option and copy the result. That works only on typed characters. It does not change the letters inside a logo file. Uppercasing logo lettering depends on how the lettering is stored: as live text, as outlined vector paths, or as a raster image.

Converting typed text

A text case converter suits the wording around a logo, such as a draft wordmark, a tagline, a brand name for a style guide, or file and layer names. The output is plain characters. It carries no font, spacing or styling, so you see the visual result only after you set the text in the intended typeface.

Some characters do not convert one-to-one. In German, the lowercase ß is traditionally written as SS in capitals, though a capital form also exists. In Turkish, dotted and dotless i have separate uppercase forms. If a brand name uses accented or language-specific letters, check the converted output by hand before using it.

When the lowercase letters are part of a logo file

How the lettering is stored | What changing to uppercase involves | What to check
Live text in a vector file | Retype the text or use the editor's change-case command | The same font must be installed and licensed on your machine
Text converted to outlines (vector paths) | There are no characters left to convert; set new text in the original typeface or draw new letterforms | Whether the original typeface is identified and available
Raster image (or a raster embedded in a vector or PDF container) | The letters are pixels and cannot be edited as text; the lettering must be recreated | Whether an editable source file exists elsewhere

Don't judge editability from the file extension alone. An SVG, PDF, EPS or AI file can contain live text, outlined paths, an embedded raster image, or a mix of these. To find out, open the file in a vector editor and try selecting the lettering. You can also use an outline or wireframe view: true vector paths show up as shapes, while an embedded image shows up as a single box. A raster preview or thumbnail of a vector file is an image, not the editable artwork.

Why uppercase is a design change, not just a toggle

Capital letters take up different space from lowercase. Capitals sit on a uniform height and lack ascenders and descenders, and many are wider. A wordmark that was balanced in lowercase usually needs new letter spacing, sizing and alignment against any symbol once it is set in capitals. Custom-drawn lettering may have no matching uppercase forms at all. In that case the new capitals have to be designed, not converted.

Small caps and true capitals also differ. Small caps are capital-shaped letters drawn at a smaller size, and not every typeface includes them. Scaling down regular capitals to imitate small caps usually makes the strokes look too thin next to full-size letters.

Websites can display a brand name in capitals without changing the underlying text by using a CSS rule like the one below. This only affects how live web text is shown. It does not alter logo artwork or image files.

.brand-name {
  text-transform: uppercase;
}

Permission to download is not permission to modify

Being able to download a logo does not give you the right to change it. Changing a logo's lettering from lowercase to uppercase alters the artwork. Whether you may do that depends on the brand owner's guidelines and on trademark rights, which are separate from download access. Retyping or editing the lettering also depends on the font license, which governs installing and using the typeface. For a logo you do not own, ask the brand owner for an approved uppercase version rather than creating one.
