Lower quality = smaller file size. PNGs reduce the color palette for a real size cut (best on photos without transparency); JPG/WebP/AVIF use standard lossy compression.
About Image Compressor
This free image compressor shrinks your JPG, JPEG, PNG and WebP files
right inside your browser — no upload, no waiting, no account needed.
Drop in your images and compression starts instantly. For PNGs, it
intelligently reduces the color palette to cut file size without the
washed-out look you get from generic compressors; for JPG, JPEG and
WebP, it uses standard adjustable-quality compression so you can
balance file size against sharpness with a simple slider.

Frequently Asked Questions
Is this tool free to use?
Yes, completely free, with no sign-up and no limit on how many images you compress.
Are my images uploaded to a server?
No. Every image is processed locally in your own browser and never leaves your device.
Can I compress multiple images at once?
Yes — drop in as many as you like and each one compresses automatically, with no batch limit.
Will compressing reduce my image quality?
You control that with the quality slider — higher settings keep more
detail, lower settings shrink the file further. A live preview
shows you the result before you download, so there are no surprises.
Does this work well on PNG files?
Yes — PNGs are compressed using smart color-palette reduction, which
gives a real size cut while keeping photos and graphics looking clean.
It works best on fully opaque PNGs; images with transparency use a
safer, more conservative compression pass.
What image formats can I compress?
JPG, JPEG, PNG and WebP are all supported.
