Frequently asked questions
Is it safe to compress my photos here?
Yes. Compression happens entirely in your browser. Your images are never uploaded to any server, so nobody else can see them.
How do I reduce an image to 100 KB or less?
Lower the quality slider to around 60–70% and choose WebP or JPG. If the file is still too big, enter a smaller maximum width such as 1200 pixels — this usually brings phone photos well under 100 KB.
Which format should I use?
WebP gives the smallest file at the same quality and works in all modern browsers. Use JPG for maximum compatibility, and PNG when you need a transparent background or pixel-perfect quality.
Will compressing reduce the quality?
Slightly, but at 70–80% quality the difference is very hard to see while the file becomes much smaller. You can always try again with a higher quality.
