Frequently Asked Questions about Image Tools
Do image tools upload my photos to a server?
Most image tools on GMC Tools run entirely in your browser — your images never leave your device. Background removal uses secure server processing and deletes files immediately after download.
Is there a maximum image file size?
No. GMC Tools does not enforce a file size limit on image tools. Very large files (over 50 MB) may be slower depending on your device.
Can I convert between image formats for free?
Yes — PNG to JPG, JPG to PNG, WebP conversion, and Image to Base64 are all free with no limits.
Will compression reduce my image quality?
At the default 80% quality setting, most images show no visible quality loss. You can adjust the quality slider from 1-100%.
