Frequently Asked Questions
Does compress image to 500kb reduce image quality?
Lossy compression (JPEG) slightly reduces quality to achieve a much smaller file size. For most web use cases, the difference is imperceptible. Use the quality slider to find the sweet spot for your image.
Is my image uploaded to a server?
No. All compression is done using the HTML Canvas API directly in your browser. Your images never leave your device and are never sent to any server.
How do I compress an image to exactly 500KB?
Use the quality slider to reduce the file size. Start at 80% quality and work down until the file size meter shows under 500KB. Most images can reach 500KB with 70-85% quality settings.
