TGA to CSS: what changes and when it makes sense

TGA is a Truevision TGA (Targa) format. It is best known for a simple, fast-to-read layout with a clean alpha channel, established in game textures and video work. The main drawbacks are large files and no browser or social platform support.

CSS is not an image format. It is a CSS snippet that wraps the image data as text. Its main appeal is keeping small icons and textures inside the stylesheet with no extra request. The main drawbacks are a bigger stylesheet that blocks rendering, and no separate caching for the image.

TGA vs CSS at a glance

Property	TGA	CSS
Type	Raster image	Text encoding of an image
Compression	Uncompressed or run-length encoded (RLE)	The image bytes are written out as Base64 text, which adds about 33 percent to the size
Transparency	Full alpha channel with soft edges	Same as the embedded image
Animation	No	Same as the embedded image
Colour depth	8, 16, 24 or 32 bits per pixel, including an 8-bit alpha channel	Same as the embedded image
Support	Supported by game engines and 3D tools, but not displayed by browsers	Works in all modern browsers
History	Created by Truevision in 1984 for the TARGA and VISTA graphics cards. It became a standard for video editing (Windows and Mac) and later game texture pipelines. Still widely used in Unity, Unreal and 3D tools.	CSS background-image with data URIs became popular around 2010 for embedding small icons and gradients in stylesheets. Modern bundlers (webpack, Vite) still support this pattern.

What actually changes in this conversion

CSS is an encoding of the image data, not a new compression scheme. The text is about a third larger than the binary file, so what you gain is portability rather than a smaller size.
Transparency follows the image data being encoded. CSS itself is only a text wrapper.
EXIF, GPS and camera data are stripped on every conversion. That is good for privacy, but you lose capture dates.

About TGA: history and technical details

Created by Truevision in 1984 for the TARGA and VISTA graphics cards. It became a standard for video editing (Windows and Mac) and later game texture pipelines. Still widely used in Unity, Unreal and 3D tools.

Technical: 18-byte header with image type, colour map, width, height, bit depth. Types 1, 2, 3, 9, 10, 11 for uncompressed and RLE variants. Supports 8-bit indexed, 15/16-bit high colour, 24-bit truecolour, 32-bit with alpha. Bottom-left origin by default.

Real-world size: A 1024x1024 32-bit TGA is 4 MB uncompressed, 1-3 MB with RLE. A 2048x2048 texture is 16 MB uncompressed. Game engines prefer DDS or KTX2 for shipping but TGA for authoring.

Popular tools: Unity, Unreal Engine, Blender, GIMP, Adobe Photoshop, ImageMagick, NVIDIA Texture Tools.

Alternatives: DDS (better for games), KTX2 (modern GPU texture), PNG (universal), WebP (web).

About CSS: what you get

CSS background-image with data URIs became popular around 2010 for embedding small icons and gradients in stylesheets. Modern bundlers (webpack, Vite) still support this pattern.

Technical: .icon { background-image: url("data:image/svg+xml;base64,..."); }. SVG data URIs can also use URL-encoded text (smaller than base64). For raster icons, base64 adds 33% overhead.

Real-world size: A 2 KB SVG icon as base64 CSS is ~2.7 KB, but as URL-encoded text is ~2 KB. A stylesheet with 20 embedded icons can be 40-60 KB, downloaded before first paint.

Popular tools: Webpack (css-loader), Vite, PostCSS, Sass (with helpers), online CSS minifiers.

Alternatives: External image URL (cacheable), Inline SVG in HTML, Icon font, SVG sprite.

Browser and software compatibility

TGA: Supported by game engines and 3D tools, but not displayed by browsers. CSS: Works in all modern browsers.

The CSS snippet works in all modern browsers. Keep it for small assets.

Why people move away from TGA

Browsers and most messaging apps cannot display TGA, so sharing it is awkward.
TGA files are large because compression is minimal.

Why people choose CSS

A CSS rule with the image embedded as a background keeps small icons in the stylesheet, no extra request.
It is handy for widgets and component libraries that ship as a single CSS file.

Common mistakes with TGA

Uploading TGA to a website — browsers will not display it
Forgetting alpha channel in TGA exports — some tools drop it
Assuming RLE TGA is fast — it is slower to decode than uncompressed

Best practices for keeping quality

A TGA from a game pipeline may use a bottom-left origin or channel-packed data. Compare against the original before relying on it.
Stylesheets block rendering, so a large embedded image delays first paint. Use this only for small assets.
For simple icons, an SVG data URI is usually sharper and smaller than a Base64 PNG.
Resize before converting if the image will be shown small. A 4000 pixel photo displayed at 800 pixels wastes bytes in any format.
Check the result at 100 percent zoom, especially around text, edges and gradients, before you replace any originals.
Keep your original files. Conversions to a lossy format cannot be undone.
When you convert a set of images, use the same quality setting for the whole batch. The converter handles up to 20 files at once.

TGA to CSS questions

Quick answers about privacy, quality, supported formats, file limits and how CSS works.

Why convert TGA to CSS?

CSS files are typically smaller than TGA, which makes them faster to share, send and load. The trade-off is a small amount of image detail at low quality settings.

Will converting TGA to CSS lose quality?

At 90% quality, most people cannot tell the difference. Use 85-95% for photos and you are fine.

Does CSS keep transparency?

CSS is only a text wrapper around the image data, so transparency depends on the image format inside it.

Are my files uploaded?

Never. Everything runs in your browser. Your files never leave your device. Open DevTools Network tab while processing — you will see no upload request.

Can I convert many files at once?

Yes, up to 20 files at once. Download them individually or all together as a ZIP.

Does the converter strip metadata?

Yes. Browsers do not pass EXIF data through a canvas, so GPS, camera model and dates are removed on every conversion. That is good for privacy.

Is it free?

Yes. No credits, no daily cap, no account, no watermark. The practical limit is your device memory.

SVG base64 or URL-encoded in CSS?

URL-encoded is usually 15-25% smaller than base64 for SVG, because SVG is text. For raster images (PNG, JPG), base64 is the only option.

Your files never leave your device

No upload, no account, no tracking. Everything happens in your browser using the Canvas API and WebAssembly. You can confirm this in your browser's DevTools Network tab while the tool runs — no request carries your file. See why ToolDeck is different.
