Question 1

Is this image compressor free?

Accepted Answer

Yes. Every tool on this site is completely free with no sign-up and no watermark.

Question 2

Are my images uploaded to a server?

Accepted Answer

No. Compression, resizing, converting, and cropping all happen inside your own browser. Your photos never leave your device.

Question 3

Which formats are supported?

Accepted Answer

JPG (JPEG), PNG, and WebP. PNG files are saved as WebP when compressed because WebP gives much smaller files.

Question 4

What quality setting should I use?

Accepted Answer

For most photos, 60–80% gives a big reduction in size with no visible loss. Use a lower value if you must meet a strict KB limit.

Question 5

Can I compress many images at once?

Accepted Answer

Yes. Select several images together, then download them one by one or all together as a single ZIP file.

Question 6

How do I get an image under 100 KB or 200 KB?

Accepted Answer

First resize it to smaller dimensions with the Resize tool, then lower the quality slider in the compressor until the size is under the limit.

Question 7

Does it work on mobile phones?

Accepted Answer

Yes. The site works in any modern browser on Android, iPhone, tablets, and computers.

Question 8

Is there a file size limit?

Accepted Answer

Each image can be up to 10 MB in the compressor and 20 MB in the other tools.
