Question 1

Is this image compressor free to use?

Accepted Answer

Yes — completely free, with no sign-up, no account, and no limit on how many images you compress.

Question 2

Does compressing reduce image quality?

Accepted Answer

For JPG and WebP, yes — those formats trade detail for file size, which is what the quality control adjusts. At higher settings the difference is usually hard to see; at lower ones it becomes visible, especially around sharp edges and text. The preview updates as you move the slider, so you can judge it yourself before downloading.

Question 3

Why does my PNG offer JPG and WebP instead of just compressing?

Accepted Answer

PNG is a lossless format, so re-saving a PNG as a PNG usually produces a file that's the same size or larger — there's no quality dial for the browser to turn. Converting to JPG or WebP is what actually reduces the size. JPG can't store transparency, so transparent areas get filled with a background color you choose; WebP keeps transparency.

Question 4

What if the compressed file isn't smaller than the original?

Accepted Answer

Then the tool tells you so. The result is measured from the actual output file, not estimated from the quality setting, so an image that's already near-minimal will honestly report no reduction rather than claiming a percentage it didn't achieve. Lowering the quality setting is usually what helps.

Question 5

Will my photo's rotation come out right?

Accepted Answer

Yes — the tool reads the rotation information your camera or phone embeds in the photo and applies it automatically, so the compressed image should end up facing the same way as it does in your gallery. If you ever spot one that doesn't, rotating the photo yourself before compressing it will fix the output.

Question 6

Is my image uploaded anywhere?

Accepted Answer

No. The file is read, compressed, and downloaded entirely inside your browser — it never leaves your device, and nothing is stored on a server.
