TGA to HTML: 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.

HTML is not an image format. It is an HTML snippet that wraps the image data as text. Its main appeal is a ready-to-paste img tag with the image embedded, and no separate file to host. The main drawbacks are a larger document, no separate caching and the need to add alt text and dimensions yourself.

TGA vs HTML at a glance

Property	TGA	HTML
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 any browser and most email clients, though some mail clients block inline images
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.	HTML img tags with data URLs have been supported since the early 2000s. The pattern became mainstream with the rise of single-file HTML tools and email marketing in the 2010s.

What actually changes in this conversion

HTML 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. HTML 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 HTML: what you get

HTML img tags with data URLs have been supported since the early 2000s. The pattern became mainstream with the rise of single-file HTML tools and email marketing in the 2010s.

Technical: Produces <img src="data:image/..." alt="..." />. Can also be a background-image in inline style. Alt text and width/height attributes should be added manually. No server request needed.

Real-world size: A 5 KB icon inline is ~7 KB in HTML. Ten icons add 70 KB to the HTML, which is fully downloaded before first paint. For comparison, ten external icons via HTTP/2 cost ~10 KB + one round trip.

Popular tools: VS Code (paste image), Markdown editors with image paste, Online tools.

Alternatives: External img src (cacheable), CSS background-image, SVG inline, Next.js Image component.

Browser and software compatibility

TGA: Supported by game engines and 3D tools, but not displayed by browsers. HTML: Works in any browser and most email clients, though some mail clients block inline images.

The HTML snippet works in any browser. Some email clients block inline images.

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 HTML

An HTML snippet gives you a ready-to-paste img tag with the image embedded, which suits email templates and single-file pages.
There is no separate image file to host or link.

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.
Add meaningful alt text and width and height attributes after pasting, so layout does not shift and screen readers get a description.
Large embedded images slow the page and bloat the document. Keep them small.
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 HTML questions

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

Why convert TGA to HTML?

HTML 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 HTML lose quality?

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

Does HTML keep transparency?

HTML 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.

Do email clients display data URL images?

Some do, some do not. Gmail and Outlook.com generally display them; Outlook desktop blocks them; Apple Mail varies. For critical email images, use hosted images with absolute URLs.

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.
