Question 1

What is the difference between lossy and lossless compression?

Accepted Answer

Lossless compression reduces file size without any loss of quality, perfect for technical drawings or medical images. Lossy compression provides much larger size reduction by intelligently removing data that the human eye is unlikely to notice, ideal for web photos.

Question 2

Is it safe to upload my images here?

Accepted Answer

Absolutely. Our image compressor is 100% client-side, meaning your images are never uploaded to our servers. All compression happens directly in your browser, ensuring your data remains private and secure.

Question 3

What image formats can I compress?

Accepted Answer

You can upload and compress JPEG, PNG, and GIF files. The tool will output the compressed image in the same format you uploaded.

Question 4

How much can I reduce my image file size?

Accepted Answer

The amount of compression depends on the image and the quality setting you choose. For JPEGs, it's common to see a 50-80% reduction in file size with minimal noticeable quality difference. PNGs and GIFs will see smaller, but still significant, reductions.

Question 5

Will compressing my images affect their dimensions?

Accepted Answer

No, the compression process only reduces the file size (in kilobytes/megabytes), not the pixel dimensions (width and height) of your image. Your image will look the same, just load faster.

Question 6

Does this image compressor work offline?

Accepted Answer

Yes. Once the page has fully loaded, our tool uses your browser's built-in capabilities to compress images. You can disconnect from the internet, and it will still function perfectly, enhancing your privacy.
