Question 1

Are image files sent externally?

Accepted Answer

No. Image compression runs in the browser, and files are not sent externally.

Question 2

Can I choose the output format?

Accepted Answer

No. This tool keeps the same format as the input. Use Image Format Conversion if you need to change formats.

Question 3

Can I compress multiple images at once?

Accepted Answer

Yes. You can select multiple images and check file-by-file results and total reduction.

Question 4

Can compression increase file size?

Accepted Answer

It can happen for formats such as PNG or GIF. By default, the original file is kept when compression would make it larger.

Question 5

Can it compress SVG and GIF?

Accepted Answer

Yes. SVG stays vector-based, and GIF is optimized without intentionally removing animation.

Question 6

Can it compress HEIC / HEIF?

Accepted Answer

The initial version does not support same-format HEIC / HEIF compression. Format conversion is handled by Image Format Conversion.
