Frequently Asked Questions
How do I compress an image to a specific size like 50 KB?
Use the Compress Image to KB tool — enter your target size in KB and it will compress the image as close to that size as possible, which is perfect for online form uploads.
Do these tools reduce image quality?
Compression always trades some quality for size, but you control the target size or quality level. Resizing and converting are done at the highest quality your browser supports.
Is it safe to edit private photos here?
Yes. Images are processed entirely in your browser and never uploaded to any server.
