Frequently Asked Questions

How do I resize an image to 100KB?
+
Start with quality at 60%, compress, and check the file size. If still above 100KB, lower quality further. For very large images (5MB+), also consider reducing the dimensions using our Image Resizer first.
Can I compress a PNG without losing transparency?
+
When you compress a PNG using our tool and set the output format to PNG, transparency is preserved. Converting to JPEG removes transparency.
