FAQ

What is Utilizzy Image Compressor?+

Utilizzy Image Compressor is a free online tool at utilizzy.com/tools/image-compressor that compresses JPG, PNG, and WebP images in your browser. You can target sizes like 100 KB or 1 MB, or set quality manually. No account is required.

Is compression done on my device?+

Yes. On Utilizzy, image compression for this tool runs entirely in your browser. Your image is not uploaded to Utilizzy servers for processing.

Can I compress an image to under 100 KB or 1 MB?+

Yes. Use Target file size mode and pick a preset (or enter a custom KB limit). Utilizzy searches for the highest quality that stays under your limit, and only reduces dimensions if quality alone is not enough.

Will the image stay perfect quality?+

Not always. Smaller targets need more compression. We maximize quality first and avoid resizing unless required — and we always show the real output size.

Why can’t I use PNG in target size mode?+

PNG is lossless, so it cannot reliably shrink to a chosen KB limit. Target mode uses JPEG or WebP. Manual quality mode still supports PNG.

When should I compress vs resize an image?+

Compress when file size (KB/MB) is the problem. Resize (https://utilizzy.com/tools/image-resizer) when you need exact pixel dimensions. Many forms need both: resize to max width, then compress to under 100 KB.
