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 This Tool
JPG photos straight from a camera or phone are often much larger
than they need to be for web use. This tool re-compresses your
JPGs with a standard, well-supported lossy encoder — the same
kind of compression every photo editor uses — so you get a real
size reduction with a quality slider you control yourself. Drop
your images in and compression starts immediately, with a live
preview so you can see exactly what you’re getting before you
download anything.

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 compressed locally in your own browser and never leaves your device.
Will compressing reduce image quality?
JPG compression is lossy by nature — some detail is always
traded for file size. Higher quality settings keep more
detail with less size reduction; lower settings shrink the
file more but can introduce visible blockiness. The live
preview shows you the actual result before you download.
What quality setting should I use?
80-90% is a good starting point for most photos — a solid
size reduction with no visible quality loss. Drop lower for
thumbnails or background images where sharpness matters
less.
What if my JPG doesn’t get any smaller?
Some JPGs are already efficiently compressed. If
recompressing wouldn’t actually reduce the file size, the
tool keeps your original file rather than replacing it with
a larger one.
Can I compress multiple JPGs at once?
Yes — drop in as many as you like and each one compresses automatically, with no batch limit.
