Compress TGA Textures

Many TGA files from renderers and texture tools are saved uncompressed, 4 bytes per pixel. TGA has its own lossless run-length encoding, and re-saving with it keeps the alpha channel and every pixel while collapsing flat areas. Game engines read both forms.

Best-in-class encoders

MozJPEG for JPG, OxiPNG and palette quantisation for PNG, libwebp and libavif for WebP and AVIF, all compiled to WebAssembly.

Live before/after

See the result and its file size on your actual image before processing the batch.

Processed on your device

Your images are decoded, edited and encoded inside this browser tab by Web Workers. Nothing is uploaded to a server.

Never bigger than the original

If compression cannot beat your file, the original is returned unchanged with a note.

Frequently asked questions

How much smaller will it get?

It depends on the picture. Run-length encoding collapses runs of identical pixels, so flat-colour textures and masks shrink a lot, while noisy photographic textures barely change; then the original is kept. PNG usually compresses better and keeps alpha too, if your pipeline accepts it.

Is the alpha channel preserved?

Yes. The file is written as a 32-bit TGA with its alpha channel.

Are my images uploaded anywhere?

No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.

Can I process many files at once?

Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.

Is it free? Is there a file limit or watermark?

It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
