Why keep original file names?
When optimizing game assets, website images, or app resources, changing file names can break references in code, CSS, Cocos Creator, Unity, or HTML5 projects. This tool keeps the same names and folder paths so you can replace assets directly.

FAQ
Will this tool change my file names?
No. Single image downloads keep the original file name. ZIP compression keeps original file names and folder paths.
Does this use my Tinify API key?
Yes. You paste your own Tinify API key locally in your browser. Requests are sent directly to Tinify.
Do you store my Tinify API key?
No. The key is stored only in your browser localStorage and is not uploaded to our server.
Can I upload a ZIP file?
Yes. The tool extracts the ZIP in your browser, compresses supported image files, and creates a new ZIP for download.
What happens to non-image files in the ZIP?
By default they are skipped. You can enable "Include non-image files" to keep them unchanged in the output ZIP.
What happens if one image fails?
The failed image is kept unchanged in the output ZIP so your project structure does not break.
Does compression consume Tinify credits?
Yes. Each compressed image may count against your Tinify API usage according to your Tinify account.
