Frequently asked questions
How much file size reduction can I expect?
Most high-resolution smartphone photos see 70% to 90% file size reduction with negligible visible difference to the human eye.
Should I choose JPG or WebP?
WebP offers 25-35% smaller file sizes than JPEG at the same visual quality. Use JPEG if uploading to older legacy government portals, and WebP for websites and modern apps.
Is there any limit on image uploads?
No. You can compress as many images as you like with zero daily caps or hidden fees.
