Frequently Asked Questions

Yes. Every available tool is free to use without an account.

No. All current image and PDF tools run in your browser, so files stay on your device.

Upload a JPG, PNG or WebP image, choose a target file size, click Compress Image, then download the result.

Upload your image, select 100 KB as the target size and click Compress Image. Fylix lowers quality and, if needed, dimensions until the file is under 100 KB.

Compression removes detail that is usually hard to notice. Moderate targets look nearly identical to the original; very small targets can show visible softness. Choose Higher Quality if detail matters most.
