Question 1

Is this a TinyPNG alternative that does not upload textures?

Accepted Answer

Yes. Image Compress batch-shrinks PNG/JPG/WebP/AVIF in your browser with no account. Open https://gameimagekit.com/en/tool/compress

Question 2

Are my images uploaded to a server?

Accepted Answer

No. Image decoding, compression, resizing and packaging all happen locally in your browser — files are never uploaded to any server, secure and fast.

Question 3

How does "target size" work?

Accepted Answer

The tool uses binary search to automatically adjust the compression quality, encoding multiple times to approach your target size (KB). If the target is very small, it gets as close as possible while keeping usable quality.

Question 4

Why is PNG compression not very effective?

Accepted Answer

PNG is lossless, so re-encoding rarely reduces size much. If transparency is not needed, output as JPG; if it is, choose AVIF or WebP — AVIF usually compresses better.

Question 5

Will quality drop after compression?

Accepted Answer

JPG / WebP / AVIF are lossy — lower quality means smaller size but more visible quality loss. Use the preview and size comparison to pick a suitable quality that balances clarity and size.
