Question 1

Is the Image Compressor free?

Accepted Answer

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

Question 2

Are my images uploaded to a server?

Accepted Answer

No. Compression happens entirely in your browser using your device's own processor, so your images never leave your computer or phone. Nothing is uploaded, stored, or seen by us.

Question 3

Which formats can I compress?

Accepted Answer

JPG, PNG and WebP. You can keep the original format or convert to JPG (usually the smallest) or WebP (modern, great quality-to-size). You can compress a whole batch at once and download them together as a zip.

Question 4

Will it keep PNG transparency?

Accepted Answer

Yes — if you keep the PNG format or convert to WebP, transparency is preserved. JPG can't store transparency, so if you convert a transparent PNG to JPG we fill the transparent areas with white (never black).

Question 5

How much smaller will my images get?

Accepted Answer

It depends on the image, but photos typically shrink by 40–80% with little visible difference. You set the quality, and we show the exact before/after size and the percentage saved for each image before you download.

Question 6

Does compressing reduce quality?

Accepted Answer

You're in control. Drag the quality slider down for smaller files or up to stay near-original, optionally cap the dimensions or aim for a target size — then check the result before downloading. If a file wouldn't actually get smaller, we hand back your original untouched.
